They knew, there would have been a puddle somewhere. we have seen many cars come to Ivan with a ' customer complaint ' then it turn out they should have shared much more knowledge of the problem, could have wiped hours of work/ diagnosis.
That was my exact question to the owner. Where did 2 GALLONS of ATF go?? 🤔 He had no idea, and neither did the previous shop who had it for 9 MONTHS... We'll never know the full story, but regardless it needs a replacement transmission! 😮
It needs a new transmission? You forcing up your driveway had nothing to do with that? Ivan come on I love you but you’re just killing me on this one. No shop under the sun starts a car without checking the fluids. What are you thinking, sir, you left yourself open to get sued for a transmission and an engine.
I'm an automotive locksmith and made more for lost keys for this system than I can remember. First off it's odd they only listed 13 values. There were actually 15 but Caddy may not have used all the values on this vehicle. I had an interrogator box. Basically it was decade box with all 15 values preset on a dial and a timer. You would obviously need a cut key. We used plastic temp keys with wires coming out of them. We hooked the interrogator to them and went through the values. If the car didn't start you set the timer wait and go to the next one. I found starting in the middle and working outwards resulted in finding the value quicker. Once you found the correct value you would copy the key or cut it by code on a properly valued metal key. This was basically the first attempt at vehicle theft security before transponders. Many years after VATS as this was called was introduced someone came out with a universal bypass box. That would have been nice to have back in the day. The engineerds who gave locksmiths factory training on these told us they were impossible to defeat. lol
I was reading the wiring diagram the other day on that era theft. It appears the theft module provides a ground signal to the ecm if theft criteria is met. Can you just ground that signal and the car will fire up?
That smile on your face when the engine started is priceless. The moments like that are the ones that makes you able to grind past the hard times and not so glamorous jobs. Simply priceless, happy new year Ivan! 🎆
Burning up the clutches like that, with the fluid low.. Was not the play. I was gritting my teeth seeing you high rev like that when you know it's slipping.
@@Bryan-Hensley I think Ivan has forgotten more about cars than what we know. The owner knew about the transmission and told Ivan, "before I fix the tranny, see about getting the engine running before I sink serious money into this". Also, there's a few strange things about that car. It's been repainted (see the turquoise shock struts and firewall) and there's far too much wrong with the car to only have 58k miles on it. Its odometer has been diddled with.
@@adotintheshark4848 what are you talking about? The owner never said anything about the transmission and only asked Ivan about the no start condition.
@@Jonathan-bk3dq you don't know what the owner told Ivan behind closed doors, especially when the owner first gave the car to Ivan. You can bet Ivan looked this car over even before starting any repairs, as well.
Boy, that was hard to watch when you kept revving the engine and trying to limp it up the drive. Imagine if you were just dealing with a leak at the cooler, which caused all the fluid to drain out. That would've been a relatively minor repair. But since you continued to rev the engine while in gear, it's very possible that the 1st gear clutch pack was only partially engaged and you smoked the clutches. Those gear clutches and bands and NOT designed to slip. As I'm sure you know, the torque converter does all the slipping. Partially engaged clutch packs in an automatic can burn up in literally a matter of seconds under the right circumstances. Luckily the customer needs a new transmission anyways, so whatever damage you might have done doesn't really matter, but if it was indeed just a cooler/line leak, I'd say the customer would have good reason to blame you for any burnt clutches/bands from your repeated attempts at forcing it to drive without fluid. You got lucky on this one, but you could very well damage somebody's transmission in the future. You should really make it a habit to check trans fluid levels, and if necessary tow/push vehicles into the shop when you're in a situation like this.
I said the same thing.. I don't know what he was thinking. I was gritting my teeth, watching him burn up the clutches like that. I bet he could smell them burning
I'm an old GM guy, but when Ivan didn't check fuel or spark I knew that vats wasn't a concern for him. That told me he knew more than he was letting on. This car isn't much different in vats than many GM's that he has worked on. Chances are the replacement ecu has vats eliminated, because vats is a looming 'issue' on every GM vehicle. I know of lots of GM vehicles that went to the junkyard because they weren't worth the price to repair. 90% of the time a vats failure was a Failed ram in the ecu, the other 10% was due to a failed ignition switch, either way it was always diagnosed as a failed ECU and billed accordingly, around 2010 the price was generally $1,400, The price of a mid to late 90's GM car at the time was under $2k.
@@crisprtalk6963 the old GM guys were right. It only started because the pass key system was bypassed. It would never start until that was fixed as he showed we he hooked it back up. He intentionally didn’t mention the bypass to generate those comments. Which is about as sad as reving the hell out of a slipping transmission before checking the fluid.
Ivan, this car reminds me of the time I was driving a 59 Pink (yes, that color pink!) Cadillac in a parade and it decided to blow a transmission line right in front of the Grand Stand. The entire crowd was yelling "there's something red coming out from under your car!" Well I made it about 100 foot farther and pulled out of the parade line. The next couple of hours was spent towing the car home and fixing it. I think that mess was a memorable event for the Mayor as well. Thanks for Sharing! 🙃🙂
I had an Oldsmobile with that key security system problem. I did the same exact hack with a bunch of resistors. It worked fine for years. My problem was a poor connection between the key and reader. Great video. Thanks
I refuse to believe that Ivan reved that engine like that, I believe he knew the transmission was bad, and he did all of that we saw just to engage us to comment.. great job, as always. Ivan, enjoy your content
That's actually an issue as well. The people weren't wrong. The videos are just split into many parts. Old theft deterrent systems on most makes of this vintage or even newer come with a whole slew of problems.
Hi Ivan, Someone is not telling the truth about the transmission. Anyway, not your problem. Kudos to getting the engine running and making a work around for the ignition key immobilizer. You and Amanda have a Happy New Year.
It probably got parked many years ago for this exact problem, then over the years that goofy map sensor lost its seal and the car would not start. Ivan commented that the trans case was cracked, so I'm willing to bet that's why it sat for so long and is still in great shape with 53k miles on it...
Don’t need to be a transmission expert to know that high revving and constant shifting of an automatic w/ no fluid will burn it up in seconds. Proof is in the video. As soon as it wouldn’t go in D or R, he should have shut it down immediately and checked the fluid.
A+ on the diagnosis to get it running. F on revving it to the moon to try to get it to move without first checking the trans fluid. You knew it had been sitting for over 18 months. You check ALL FLUIDS before moving the car even with that low a mileage. It's an interesting car. I didn't check the 1st video again of the window sticker to see if that car was originally teal vs the red it is now.
I thought about that. But then it would still instantly stall and flood itself out unless you manually turned down the MAP Signal voltage at precisely the right time after start up 😂
@@PineHollowAutoDiagnostics I do simply unplug them and light them up to test if I have a completely dead one.....however, every car I do that to has a MAP sensor that I can actually unplug and plug back in real quick.....not hidden under a sealed cover!
They make a sensor signal generator I was considering buying through launch. I haven’t seen a ton of info on it yet so I haven’t been reserved to buy it
@@PineHollowAutoDiagnostics I had a dodge Dakota that had low compression from overheating hence low vacuum. I could make it run good by hooking a map sensor to a hand operated vacuum pump. A thought to keep in mind.
Thanks Ivan for the video. I've never seen the amount of folks "knowing for sure" that you were making a mistake about the theft light. After all of the vehicles you have fixed, I figured you knew what you were doing. Something slapping you in the face like that security warning and you ignoring it should have been enough for the naysayers because there is little that gets passed you. Anyway, maybe we will see this vehicle again once the transmission is fixed. Great job as usual. Happy New Year!
Agree with comments about forcing the transmission on zero ATF all the way into the shop is crazy - it's like running an engine without OIL - it will be cooked in seconds, if you get metal on metal contact anywhere.. I would not have moved the car at all, if it was not going into gear - I would check ATF level before anything else. That transmission might have been fixed with just a new case before, but now it could be destroyed.
Hey Ivan; this series is of particular interest to me, as that Allante technology is very similar to my 89 Olds Toronado Trofeo restoration project, which I am at the end of now (consumed this retired old guy's time for the past year). If I figured it out right, that power module for the blower motor is a power transister on a large heat sink, that receives PCM or maybe PWM signal from the HVAC Programmer, and that transister pulses the battery voltage at much higher current to the motor. There is also a feedback signal for the system to monitor the blower motor "battery" voltage, so it can vary it as needed. Mine works same as that : VIC sends driver requested internal temperature to the BCM, which sends signals to the HVAC Programmer which operates the blend door with a mechanical rod, then routes the vacuum signals to open the required vents in the air box. The Programmer then sends pulse signals to that blower motor power module to control the speed of the motor. Have I mentioned how much I love this Toronado ? I had to stop adding up the costs of this restoration, before I ended up shooting myself. Luckily we still have shops in my area that are willing to work on these old transmissions.
Another great series of video's. Thank you Ivan for sharing this with us and indeed thanks for all the videos over the past year.....Happy New Year to you and the family and hopefully 2025 will be good to you.....cheers
Dear Ivan, in the near future for the love of God always please check your transmission fluid level before putting it in gear even on front wheel drive they have some sort of a fluid level check on the side of the transmission. You should never ever be rev the engine that high and not be moving. Some simple tips which automatic transmission when you check the fluid level if the fluid level is way above the fill line don't worry about it that is pretty normal for the converter to drain back the fluid into the pan the car needs to be in park or neutral and running to do a proper check and then once you get it at that level then cycle the gears few time and recheck, Based on the amount of fluid that is coming out I'm pretty sure that the transmission converter seal popped off because the retainer clip was either missing or didn't hold due or due the fact that it wasn't able to drain back into pan, Usually this is caused by a worn out torque converter pump bushing as the pressure is so great that it literally can't drain back in pan fast enough so it blows the seal out. Sidenote because the amount of dirt around Transmission case and pan suggests that it was already been leaking previously.
@joeyh7796 what? All older vehicles have a way to check fluids. The guy is right always check fluids especially the engine oil . Especially the trans fluid when you put vehicle in gear and it doesn't move. It doesn't take much to smoke the clutches on an auto trans.
Mixed feelings, Ivan! On one hand, you were right and the car runs ( 👏👏). On the other, there is something more wrong with the blower control, and the cascade of transmission fluid is something that customer (or the other shop) must have known all along - it's not a missable problem (car doesn't move without fluid, and new fluid goes straight to the ground). Hope there will be a follow up on this - I'm very curious 🙂 Happy New Year!!
The VATS security has been a pain in the ass for the 4th Generation F-body (Camaro and Firebird) community for years. What often happens is that the wire that goes from the ignition cylinder through the steering column breaks, and then you cannot start the car. It gets broken over time because the wire rubs inside the column. You can replace it and the new cylinder has a new key without the resistor. You have to get a locksmith to get you the right key and cut that key to match the key that came with the cylinder. A real pain. Several small companies sell a bypass kit that does what you did with the resistors. It makes the car "easier" to steal, but who is stealing those cars these days.😂 Nice work on bypassing it with a low cost solution.
Oh my young man Ivan I also sensed a problem with the no start two episodes ago with those funky readings! I went to a one week diagnostic workshop at the GM training center in Hinsdale, Illinois back 35 years ago. The knowledge that I learned was invaluable. I can’t believe so many technicians are lacking in simple electronic diagnostics. Well played.
Will 2025 be the year Ivan treats himself to a 4 post lift??? 2 post... ;-) Love the channel man, really appreciate your technical ability and transparency in your diagnostic approach to the crates people bring/dump on your drive!!
I said the same thing.. He needs to build a separate shop right next to the garage.. At an angle, so that you can still use the same driveway.. And just make it a 3 or 4 car garage -- with a dedicated lift. Leave your old garage for 'parking cars" -- and put all your tools in the new shop. He deserves to have a dedicated shop setup. Make it at least 30 ft deep, so you can have a work bench all along the back wall.. and tool boxes, etc. Depending on how much work you do yourself, you could get it built for 40k to 100k... You could even get fancy and put an apartment above, in the attic.
I'm going to lose my mind watching Ivan slipping that poor transmission over and over again. At least that transmission is rebuildable/replaceable. Should be a 4T80E. And I guess it's possible it was already hurt before Ivan touched it.
@PineHollowAutoDiagnostics Ah. Well slipping clutches or not it will have needed a new one anyway. It'll be harder to find a junkyard one for this. Also it's a bit of a bear given the size of the transverse engine/trans setup.
@@PineHollowAutoDiagnostics There used to be a ton of Northstar/4T80E cars roaming the streets. I don't think it's anything too unusual for any shop that can R&R a transmission.
Ivan…I’m only 4:30 into the video….what a great way to DESTROY a customer’s transmission. Just keep on shifting from gear to gear and flooring the accelerator without checking transmission fluid. If you didn’t burn up the pump, the wear you just put on it is unacceptable. I humbly admire your diagnostician skills, but come on brother….apply some common sense in these mechanical situations. There is obviously something wrong…continued revving and shifting is not going to magically fix the problem….good grief! I know it’s not your car, but you should treat it as such. On edit: @ 5:10 “it’s smoking”…no 💩 Sherlock. @ 5:50 “it needs transmission fluid NOW”….you think?
Dude! NEVER..NEVER..NEVER rev the engine trying to get a vehicle who's transmission wont go into gear because of low fluid to move .. lawd have mercy! Burned up pump...clutch packs..trash afterwards!
The countdown is a purposeful delay to stall any theft attempts. In different cars, it's also timed differently for some reason. The car will allow you to "attempt" to start it, and if you're unsuccessful after a certain amount of times, it'll shut off attempts. It thinks you're trying to steal the vehicle. There were about 10 different codes GM used in some of these vehicles. The "chip" key designs used in these were a royal pain. Buick was also early in using electronic dashboards, along with certain Oldsmobile models, mainly the Toronado and the Riveria. As to MAP sensors, I've had them go on those years of GM. Almost all others used a vacuum hose with the sensor mounted on the firewall. They had polarized plugs on them so that even though they looked the same, the plugs were different. Electric EGR valves of different designs were also coming out then and they too were a pain. Not very good years for electrical experimentation. Bad years for a lot of cars made back then.
I think Ivan fooled us. He knew all along the transmission was toast, was probably informed by the owner, who wanted him to fix other issues first. So he proceeded to "burn up" the transmission to see what kind of reaction he'd get. Well, it seems he got one!
@adotintheshark4848 The transmission was not his task, the car was towed and unloaded in his driveway identified as a no start, 9 months at a different repair facility. He was not taking it for a trip to town but moving it indoors. You would think the owner or previous shop staff members would have checked and corrected the fluid levels.
@wayneessar7489 but even just to bring the car into the shop like that, you don't " force" it. First thing, you check for fluid. I think Ivan knew all along that car was a " no go" and just wanted to see if the car would actually get to the garage.
VATS system: I bought an 89 Firebird brand new. At 40k miles the security light would illuminate and car wouldn't start. Cycling a couple of times got me home. I found the same wires under the column you did, no key measured. Found one of the wires had broken off at the key tumbler. I owned the car up until 160k miles. The wires would break at roughly every 40 to 50K miles. The wires at the tumbler were so small and got flexed with every key cycle. Poor design.
Ivan, I know you have permitting issues to deal with but you REALLY need a lift if you are going to continue to work on cars. Believe me, it will further your career because, even though you are young now, your body will catch up to you. Ask me how I know😊😊
Boy are you right! I'm 78, and if I was Ivan's age, with his incredible knowledge, I would find a way to build a conditioned three high bay butler building with three bendpack lifts in it. I'd also build a bed and breakfast right on his land where his clients could stay as he waved his magic wand over their vehicles. Were I him, I would talk to the town muck-e-mucks about the revenue he would bring in to the town. Money Talks.
@@jedclampett6466 sure, engaged just fine after dumping in a gallon of ATF 😂 It was puking it back out about a quart per minute though... What a waste of good ATF 😆
Actually, no that's not how that works, usually what happing to clutch is burn out as they wear out overtime, they get too thin with too much clearance and the piston cannot stay sealed any more or you're not getting enough pressure to apply the pistons There are a few things that can cause this. More than likely they were actually transmission is fine it just needs to have the pump rebuilt but it's all gonna depend on what happened If there is what I think happened then the torque converter seal blew out there's a couple things that can cause this issue
Every Transmission builder on the Planet’s eye’s just popped out of there head and with all those rev’s. You have just cost this customer a Transmission guaranteed all those friction disc’s are fried…..Time for a Rebuild. You should have checked the level before even starting this car…….Pump Seal is blown out. 😳😳🙄🙄
Interior took some cues from Alfa Romeo. Beautiful car with some awesome technology. I don't think the public knew how much engineering was behind this car.
As soon as he tried driving and I knew the trans was probably dry I ran to the comments. 😂😂😂 Yep Ivan, you bought this customer a transmission!!!! Crazy rookie move man.
Ivan, Thanks for another great year of PHD videos! Looking forward to more great case studies in 2025. Wishing you and your family a Blessed and Happy New Year!
The layers of the onion are unfolding. Those 4T80 transmissions are no fun to replace. I’ve done a few. I place the resistors in the harness right where you did. The pump bushing probably worked its way out and pushed the seal out. Seen it before. I call them “Junkallac”. Great job Ivan!
look inside of the lock cylinder. There are two tabs where the key resistor touches. People push the key too hard and bend them Add a resistor where the meter is plugged in
So now I am curious how the transmission case got cracked! I have a hate-hate relationship with almost every 4-speed GM front wheel drive transmission...except the 4T80E which were pretty stout.
I'm willing to bet that is why the car got parked many years ago.... Trans was broken and extremely expensive to repair. Then over the years the map sensor failed, and it turned into a no start at which point it was sold and the new owner had no idea about the underlying trans issue?
@@volvo09watch Part 1 again... Owner said it was driving fine last year, then wouldn't rev after sitting for 4 months at which point he took it to his buddy's shop. After 9 months there, now it doesn't start at all and apparently has a busted transmission... 😮😬
Sure..if you wanna pay 164,000 bucks. Looks like this car was the first to have many of the modern systems we think are standard these days. It looks like the allante was a gm test bed for the innovations they were trying and adopted later
Chrysler has been doing codes for years search RUclips Chrysler triple click key code or something along those lines.. Volvo does some stuff to RUclips it lol
Here's and FYI This issue pertains to The Buick Rivera's of the late 80's early 90"s with the Touch screen Green colored MonoChrome CRT Monitor Screen in the dash EG 1989 Buick Rivera Plus the 1992 Cadilliac STS/CTS with the 4.9 L V8's or 300 CUI V8. There is other GM Vehicles of the same Era's that use the Passkey Anti Theft system too that are affected as well. To tell if your GM vehicle has the Anti theft system look at your ignition key for a weird bump/bubble towards the key ring end . In the center of that bump is 2 metalic contacts on each side of the key. This is a Resistor inside the Tumbler there's a sensor in there that contacts those 2 contact points on the key. The sensor is connected to the pats module in the Trunk Mounted to rear of the backseat behind a cover you pull off from inside the trunk. The theft module has a preset from factory Resistance Value it looks for from the resistor in the key via the sensor in the tumbler. The issue is its a bad design because there's 2 really thin wires that exit the tumbler that actually move when you turn the key and they get weak and after a while they break and they don't always brake and show visible signs of being broken as they can/will brake with insulation intact which is something to take note of. I found this out from helping a Relative with his 92 Cadilliac CTS. which left him Stranded thankfully in a Parking Lot and not on the side of the road.
I could see you being an instructor for automotive electrical systems troubleshooting/diagnosis courses. In my opinion you could offer some of the best training out there. Fancy systems are easy to overthink and take a wrong direction, way to go on keeping it simple and zeroing in on the map sensor!
I am really surprised the PCM did not have a default strategy when the MAP was disconnected. Usually a MAP, MAF, TPS etc all have a limp mode to still run the car.
Interesting that they sent the car to you knowing it bleeds trans fluid. They should have mentioned that to you. Interesting the MAP was toasted like a hot dog in that cavity. Based on the evidence from past work and modules galore, electrical clusters and so forth...I doubt working any further on this car is going to be worth the time. Unless the customer has said he was done with the other shops and his plans were to get the car into completely normal operation and functions, I'd pass working on it due to parts availability. As long as the owner is going to pay for the labor its going to take just to diagnose this pig, it will make money but I'd want to be sure the owner isn't going to call it quits half way into spending much money.
Time for the owner to punt this car. An Allante' enthusiast with knowledge, experience and needed resources would love this very low mileage, rare gem.
Def not original key. It has a GM logo on it. Cadillacs all have keys with a caddy symbol on them. Cadillacs are status symbols and even need to show that status when you throw your keys on a table somewhere. Being a GM key they have 15 different pellet resistor sizes. Key value 14 is 9540 ohms. In pro demand it shows 15 different keys for the Allante as well. Doesnt make sense that the amount of resistance to make it start falls between #13 and 14. Ive bypassed several of these but i add a toggle switch inline so customer can still disable the ignition and at least slow someone down trying to steal it. Forgot to add i reallty did not think map would fix it. Thought they had a default parameter to use when faults were detected. Figured unplugged would run on a default value. Learned something today.
Fluid was exiting way too fast for a seal failure. Think main seal on the engine. The input seal does not hold pressure. The large stream suggested a breached fluid passage or cooler line.
Love the 14 yrs expired PennDOT inspection sticker! If I'm not mistaken, Eric O. had a pretty good work around/hack for that pass key system a couple yrs back (I may very well be thinking of a different generation, though. Not sure.)
I think you could rebuild / improve the HVAC Power Module over the factory version and the Rock Auto version. You would need to measure the characteristics of the cooling fan; current at voltage, resistance, inductance, etc. and take apart the original bad unit to see how it is packed / designed. If the unit is not potted than the repair / upgrade could be a simple output power switch replacement. I say this because automotive power device design has improved greatly from when the car was originally sold. What do we know from the Rock Auto replacement HVAC Power Module: The output power switch is a Bipolar Junction Silicon Transistor 2N5684G PNP 50 Amp 60-80V 300W in a TO-3 Power Package from ON Semiconductor. Being the output power switch is PNP we know that the fan motor switching power amplifier drive is high side, just like the wiring diagram indicated. When the fan is commanded full on the module will probably dissipate around 13 Watts of power, which is a lot for a high side power switch. With a smart high side automotive driver, depending on the switching frequency you could probably get this down to 2 Watts or lower, and have many more protection features than the 2N5684G.
It blows my mind that a mechanic would keep trying to move this car without immediately checking trans fluid at the first signs the trans wasn't engaging properly.🤯🤯
Yes that may be exactly what blew out the front seal? Low fluid, and reving it up like that. Car's sit a long time, you better check for tranny fluid when it doesn't want to move? It was probably going bad, even before sitting. Poor Ivan! He did a good job on bypassing the key reader module.
This car went from a snowflake to a damn avalanche real quick lol 😂 Some fire starter and a box of matches will fix that thing up really quick 🔥🔥💥 What a nightmare that car is .... Happy New Year's Eve Ivan and to all of the YT community😊
The 4T80E front wheel drive Transmission can be rebuilt if you can source parts such a new oil pump for it. Richard Crich of Precision Transmissions ln Amarillo Texas is a good person to talk to about rebuilding the transmission but you would have to tow it for 1 day from State College in the U.S to get there !.
Usually, what happens is the contacts in the switch fail. My son, who is an automotive locksmith, uses the resistor module in a spare key, solders leads to each side, then cuts the two wires going to switch and inserts the resistor module. The security system is now forever happy.
That thing is a PITA & if you remember I asked the rhetorical question why transverse engine mount for the obvious reason of transmission mounting would have been able to put a known more robust one inline to a rear wheel drive kudos for all the effort to even get that PIG to start & run.Also someone must have known about the trans can not believe that it failed just sitting around for how ever it did.Cheers Ivan you win more than you lose.😂
Wiring a resistor in place of the key was the way to bypass the pass lock when installing an after market remote starter. The pass lock module will relearn the new resistance value after 10 minutes.
This is Vatts which the voltage value is a non relearnable hard coded into the module. It is one of 15 different values. You are thinking about Passlock1 in which a magnet in the lock cylinder rotates past a hall effect sensor pulling down the 5V from the BCM into a value. This value can be relearned after 10 minutes with key on after start fail.
Smart to leave transmission issues to someone else. Too many parts if you need to rebuild it. For those of you who do, you guys played with too many rubics cubes growing up
All the internet expert warriors saying about the theft system in the last 2 episodes as if Ivan's some sort of complete dunderhead.......Careful people they walk amongst us!
The car had a theft system problem , that had a bypass box done prior that still kept the antitheft light on. This was not known or looked into until after the MAP sensor problem was discovered. The original antitheft module, if not bypassed, would have prevented the car from cranking and running. In the end there was nothing wrong with the original antitheft module ,but there was a problem with the key pellet reader in the ignition switch. Adding the correct resistance, as a substitute fixed that very real problem. This antitheft , aka VATS, Passkey etc, has driven people crazy since about 1986 on the Corvette.
Just read up about the Allanté, what a crazy production process. I think it's a cool looking car but damn it was expensive but not surprising as the production costs must of been through the roof.
What is wrong with people? How the hell is Ivan supposed to know that transmission was cracked and leaked out? The car was brought to him for a no start problem and not a transmission problem. He's not psychic, how was he supposed to know?
Seeing that transmission puking ATF fluid reminds me of our 97 Taurus...it had a huge crack in the case. When i drove it at hiway speed the torque converter would lock up and it drove OK, but once speed was reduced, it barely moved. Is why i will never own another Ford.
Love your diagnostics but Was cringing the whole time trying to drive it. Ida checked fluid immediately once i realized it wasn’t moving or moving well. Sounds like trans was broken already…needed a case?
If that transmission is a 440 and it really is the input seal, the input shaft bushing is wasted. Needs a torque converter, seal and new bushing. In some cases, metal fragment damge also. Replace transmission. GM T.S.B
The owner was lucky to find someone to work on this dinosaur lol I’ll doubt there’s a factory service manual that’s even available for it!! GM sent them to us before the cars were even delivered as well as any special tools needed to work on them. I did a PDI on a new Allante!! Great video Ivan !!!!
ALLDATA has most of the original GM shop manual information for the vehicle. I think for this vehicle the complete printed version of shop manuals includes the manual Ivan has and a Electrical Diagnosis Service Manual Supplement.
Broken wires inside the tilt column is probably at fault causing theft deterrent. The a/c heater control modules were a problem since day one. Trans front pump seal is old and cracked and leaking. Welcome to Cadillac's money pit car!
Wow! Ivan, I cannot believe what you did to that transmission! Smoked it! You even said that the fluid needed to be checked after you rev'd it to the moon, in forward and reverse a bunch of times. Did you check it? No! You just kept reving it until it moved a bit down the lane and really started smoking with no further movement. Then, you check the fluid level to find a dry stick. You checked the engine oil at that point as well. This all goes against your typical M O of checking all fluids before starting and driving a vehicle brought to you. How is the coolant level? Did you check that? In my opinion, you owe the owner transmission service to replace all affected friction components that are very likely damaged by your irresponsible actions. What the heck was that, a momentary loss of consciousness? You are better than that. Or at least you were.
@@douganderson7251 No. How would he have known the tranny had a crack in it? He would have stated so if he'd discovered it. He was surprised by the fact that the car wasn't moving in any gear. Plus, crack or no crack, wisdom dictates that you ought not to try to drive a car that is out of tranny fluid. Besides, us viewers don't know for a fact that the tranny has a crack in it.
UPDATE: For everyone down here jumpng down Ivans neck about him supposedly breaking the transmission, see the first comment here in the comments. Ivan states that a large crack was later discovered in the transmission housing. Eeeeeeeeveryone take a deep breath and eeeeeease back a bit.
It'll eventually come up in value. Eventually. Right now they are really cheap. But you are screwed if there's any interior damage or exterior trim damage. All unobtainanium. I wouldn't even consider a Northstar one like this one. Add all the nightmares plus all early Northstar issues.
There's no way the customer/other shop didn't know there was a transmission fluid leak in that car
They never got it started.
@metatechnologist the fluid leaked out on someone's driveway or workshop floor given it was completely empty
They knew, there would have been a puddle somewhere. we have seen many cars come to Ivan with a ' customer complaint ' then it turn out they should have shared much more knowledge of the problem, could have wiped hours of work/ diagnosis.
That was my exact question to the owner. Where did 2 GALLONS of ATF go?? 🤔
He had no idea, and neither did the previous shop who had it for 9 MONTHS... We'll never know the full story, but regardless it needs a replacement transmission! 😮
It needs a new transmission? You forcing up your driveway had nothing to do with that? Ivan come on I love you but you’re just killing me on this one. No shop under the sun starts a car without checking the fluids. What are you thinking, sir, you left yourself open to get sued for a transmission and an engine.
I'm an automotive locksmith and made more for lost keys for this system than I can remember. First off it's odd they only listed 13 values. There were actually 15 but Caddy may not have used all the values on this vehicle. I had an interrogator box. Basically it was decade box with all 15 values preset on a dial and a timer. You would obviously need a cut key. We used plastic temp keys with wires coming out of them. We hooked the interrogator to them and went through the values. If the car didn't start you set the timer wait and go to the next one. I found starting in the middle and working outwards resulted in finding the value quicker. Once you found the correct value you would copy the key or cut it by code on a properly valued metal key. This was basically the first attempt at vehicle theft security before transponders. Many years after VATS as this was called was introduced someone came out with a universal bypass box. That would have been nice to have back in the day. The engineerds who gave locksmiths factory training on these told us they were impossible to defeat. lol
I was reading the wiring diagram the other day on that era theft. It appears the theft module provides a ground signal to the ecm if theft criteria is met. Can you just ground that signal and the car will fire up?
That smile on your face when the engine started is priceless. The moments like that are the ones that makes you able to grind past the hard times and not so glamorous jobs. Simply priceless, happy new year Ivan! 🎆
Burning up the clutches like that, with the fluid low.. Was not the play. I was gritting my teeth seeing you high rev like that when you know it's slipping.
Honestly, I thought the engine was leaking oil when I watched. I had no idea it was the transmission at first.
No kidding..he showed his weakness. He knows nothing about transmission rebuilds. I had to fast forward through that part.
@@Bryan-Hensley I think Ivan has forgotten more about cars than what we know. The owner knew about the transmission and told Ivan, "before I fix the tranny, see about getting the engine running before I sink serious money into this". Also, there's a few strange things about that car. It's been repainted (see the turquoise shock struts and firewall) and there's far too much wrong with the car to only have 58k miles on it. Its odometer has been diddled with.
@@adotintheshark4848 what are you talking about? The owner never said anything about the transmission and only asked Ivan about the no start condition.
@@Jonathan-bk3dq you don't know what the owner told Ivan behind closed doors, especially when the owner first gave the car to Ivan. You can bet Ivan looked this car over even before starting any repairs, as well.
Boy, that was hard to watch when you kept revving the engine and trying to limp it up the drive. Imagine if you were just dealing with a leak at the cooler, which caused all the fluid to drain out. That would've been a relatively minor repair. But since you continued to rev the engine while in gear, it's very possible that the 1st gear clutch pack was only partially engaged and you smoked the clutches. Those gear clutches and bands and NOT designed to slip. As I'm sure you know, the torque converter does all the slipping. Partially engaged clutch packs in an automatic can burn up in literally a matter of seconds under the right circumstances. Luckily the customer needs a new transmission anyways, so whatever damage you might have done doesn't really matter, but if it was indeed just a cooler/line leak, I'd say the customer would have good reason to blame you for any burnt clutches/bands from your repeated attempts at forcing it to drive without fluid. You got lucky on this one, but you could very well damage somebody's transmission in the future. You should really make it a habit to check trans fluid levels, and if necessary tow/push vehicles into the shop when you're in a situation like this.
Very well stated.
Yeah, totally agree. He at least took a lot of life out of those clutches.
Can't believe you tried to keep driving that car without checking the fluid!
good way to fry it
Unbelievable
Ya exactly my thought!
I said the same thing.. I don't know what he was thinking. I was gritting my teeth, watching him burn up the clutches like that. I bet he could smell them burning
@ I was yelling at the screen. Stop!
I could hear all the old GM guys here screaming theft system for two days die inside when it started with the MAP sensor. 🤣🤣
I was one of those people agreeing with theft. It should have been a starting place
LOL they don't understand script creation and movie editing. Code 319 on DSM 5.
I am not an old GM guy but I did say in part 1 that I thought it wouldn't start with just a MAP sensor.
I'm an old GM guy, but when Ivan didn't check fuel or spark I knew that vats wasn't a concern for him. That told me he knew more than he was letting on.
This car isn't much different in vats than many GM's that he has worked on. Chances are the replacement ecu has vats eliminated, because vats is a looming 'issue' on every GM vehicle. I know of lots of GM vehicles that went to the junkyard because they weren't worth the price to repair. 90% of the time a vats failure was a Failed ram in the ecu, the other 10% was due to a failed ignition switch, either way it was always diagnosed as a failed ECU and billed accordingly, around 2010 the price was generally $1,400, The price of a mid to late 90's GM car at the time was under $2k.
@@crisprtalk6963 the old GM guys were right. It only started because the pass key system was bypassed. It would never start until that was fixed as he showed we he hooked it back up. He intentionally didn’t mention the bypass to generate those comments. Which is about as sad as reving the hell out of a slipping transmission before checking the fluid.
Ivan, this car reminds me of the time I was driving a 59 Pink (yes, that color pink!) Cadillac in a parade and it decided to blow a transmission line right in front of the Grand Stand. The entire crowd was yelling "there's something red coming out from under your car!" Well I made it about 100 foot farther and pulled out of the parade line. The next couple of hours was spent towing the car home and fixing it. I think that mess was a memorable event for the Mayor as well. Thanks for Sharing! 🙃🙂
I had an Oldsmobile with that key security system problem. I did the same exact hack with a bunch of resistors. It worked fine for years. My problem was a poor connection between the key and reader. Great video. Thanks
I find that " Welcome to the world of Cadillac, " message in that Allante book so funny! Welcome to the World of trouble, it should say!! LOL!
If the trans wasn't burnt up it is now racing the engine like that
That’s what I’m saying lol. I’m pretty sure he caused that blow out/leak by revving the bejesus out of it with no fluid.
Poor clutches trying to move the car up a steep grade with no fluid lol
@@remodz6385 What a dumb comment. The reason the car wouldn't move was because the fluid HAD ALREAY LEAKED OUT when he got it it.
I refuse to believe that Ivan reved that engine like that, I believe he knew the transmission was bad, and he did all of that we saw just to engage us to comment.. great job, as always. Ivan, enjoy your content
When my GM trans leaked like that it was a cracked trans pump. Thank Goodness for the warranty.
The theft light experts are pretty quiet in this comment section
😂
That's actually an issue as well. The people weren't wrong. The videos are just split into many parts. Old theft deterrent systems on most makes of this vintage or even newer come with a whole slew of problems.
@@inducedapathy1296 They were wrong. ALL of them!
@@inducedapathy1296 car started right up with the new map sensor ivan was right the keyboard experts were wrong
To be fair, people are invited to place their bets in the comments 😊! It all adds to the excitement.
Hi Ivan,
Someone is not telling the truth about the transmission. Anyway, not your problem. Kudos to getting the engine running and making a work around for the ignition key immobilizer. You and Amanda have a Happy New Year.
It probably got parked many years ago for this exact problem, then over the years that goofy map sensor lost its seal and the car would not start.
Ivan commented that the trans case was cracked, so I'm willing to bet that's why it sat for so long and is still in great shape with 53k miles on it...
The armchairs shapeshifted from Theft system experts to Transmission fluid experts in a heartbeat🤣
I'm ASE Certified armchair mechanic, 35 years so I'm Right an listen to me
Yep.
Took my first ASE's in 1973. What are your credentials?
Don’t need to be a transmission expert to know that high revving and constant shifting of an automatic w/ no fluid will burn it up in seconds. Proof is in the video. As soon as it wouldn’t go in D or R, he should have shut it down immediately and checked the fluid.
You can't put the smoke back. That tranny is done!
4:15 wouldn’t you pulling the trans stick by now?
A+ on the diagnosis to get it running. F on revving it to the moon to try to get it to move without first checking the trans fluid. You knew it had been sitting for over 18 months. You check ALL FLUIDS before moving the car even with that low a mileage. It's an interesting car. I didn't check the 1st video again of the window sticker to see if that car was originally teal vs the red it is now.
There was an easy way to test is it's actually the MAP sensor. Send slightly less than 5 V to its signal wire and try to start up.
I thought about that. But then it would still instantly stall and flood itself out unless you manually turned down the MAP Signal voltage at precisely the right time after start up 😂
@@PineHollowAutoDiagnostics I do simply unplug them and light them up to test if I have a completely dead one.....however, every car I do that to has a MAP sensor that I can actually unplug and plug back in real quick.....not hidden under a sealed cover!
They make a sensor signal generator I was considering buying through launch. I haven’t seen a ton of info on it yet so I haven’t been reserved to buy it
@@PineHollowAutoDiagnostics I had a dodge Dakota that had low compression from overheating hence low vacuum. I could make it run good by hooking a map sensor to a hand operated vacuum pump. A thought to keep in mind.
@@charliemagoo7943 A hand operated vacuum pump, you say... was it Swedish made? *_"That's not my bag, baby!"_*
Thanks Ivan for the video. I've never seen the amount of folks "knowing for sure" that you were making a mistake about the theft light. After all of the vehicles you have fixed, I figured you knew what you were doing. Something slapping you in the face like that security warning and you ignoring it should have been enough for the naysayers because there is little that gets passed you. Anyway, maybe we will see this vehicle again once the transmission is fixed. Great job as usual. Happy New Year!
Agree with comments about forcing the transmission on zero ATF all the way into the shop is crazy - it's like running an engine without OIL - it will be cooked in seconds, if you get metal on metal contact anywhere..
I would not have moved the car at all, if it was not going into gear - I would check ATF level before anything else. That transmission might have been fixed with just a new case before, but now it could be destroyed.
Hey Ivan; this series is of particular interest to me, as that Allante technology is very similar to my 89 Olds Toronado Trofeo restoration project, which I am at the end of now (consumed this retired old guy's time for the past year). If I figured it out right, that power module for the blower motor is a power transister on a large heat sink, that receives PCM or maybe PWM signal from the HVAC Programmer, and that transister pulses the battery voltage at much higher current to the motor. There is also a feedback signal for the system to monitor the blower motor "battery" voltage, so it can vary it as needed. Mine works same as that : VIC sends driver requested internal temperature to the BCM, which sends signals to the HVAC Programmer which operates the blend door with a mechanical rod, then routes the vacuum signals to open the required vents in the air box. The Programmer then sends pulse signals to that blower motor power module to control the speed of the motor. Have I mentioned how much I love this Toronado ? I had to stop adding up the costs of this restoration, before I ended up shooting myself. Luckily we still have shops in my area that are willing to work on these old transmissions.
What was wrong with a lever attached to a choke cable? 😢
Another great series of video's. Thank you Ivan for sharing this with us and indeed thanks for all the videos over the past year.....Happy New Year to you and the family and hopefully 2025 will be good to you.....cheers
This is way more captivating than any drama series currently on TV. lol
Dear Ivan, in the near future for the love of God always please check your transmission fluid level before putting it in gear even on front wheel drive they have some sort of a fluid level check on the side of the transmission. You should never ever be rev the engine that high and not be moving. Some simple tips which automatic transmission when you check the fluid level if the fluid level is way above the fill line don't worry about it that is pretty normal for the converter to drain back the fluid into the pan the car needs to be in park or neutral and running to do a proper check and then once you get it at that level then cycle the gears few time and recheck, Based on the amount of fluid that is coming out I'm pretty sure that the transmission converter seal popped off because the retainer clip was either missing or didn't hold due or due the fact that it wasn't able to drain back into pan, Usually this is caused by a worn out torque converter pump bushing as the pressure is so great that it literally can't drain back in pan fast enough so it blows the seal out. Sidenote because the amount of dirt around Transmission case and pan suggests that it was already been leaking previously.
Car comes in for a no start, so let's check the transmission oil... how insane are you?
@@georgecaspira and most cars don’t even have an easy way for you to check it. some people don’t make any sense
@joeyh7796 what? All older vehicles have a way to check fluids. The guy is right always check fluids especially the engine oil . Especially the trans fluid when you put vehicle in gear and it doesn't move. It doesn't take much to smoke the clutches on an auto trans.
@@joeyh7796 I know right, it would have been great if Ivan was told there maybe a Transmission problem, he would have diagnosed/ checked accordingly.
He was told there was a transmission problem the second it didn't move in gear
Mixed feelings, Ivan! On one hand, you were right and the car runs ( 👏👏). On the other, there is something more wrong with the blower control, and the cascade of transmission fluid is something that customer (or the other shop) must have known all along - it's not a missable problem (car doesn't move without fluid, and new fluid goes straight to the ground).
Hope there will be a follow up on this - I'm very curious 🙂
Happy New Year!!
The VATS security has been a pain in the ass for the 4th Generation F-body (Camaro and Firebird) community for years. What often happens is that the wire that goes from the ignition cylinder through the steering column breaks, and then you cannot start the car. It gets broken over time because the wire rubs inside the column. You can replace it and the new cylinder has a new key without the resistor. You have to get a locksmith to get you the right key and cut that key to match the key that came with the cylinder. A real pain. Several small companies sell a bypass kit that does what you did with the resistors. It makes the car "easier" to steal, but who is stealing those cars these days.😂
Nice work on bypassing it with a low cost solution.
Oh my young man Ivan I also sensed a problem with the no start two episodes ago with those funky readings! I went to a one week diagnostic workshop at the GM training center in Hinsdale, Illinois back 35 years ago. The knowledge that I learned was invaluable. I can’t believe so many technicians are lacking in simple electronic diagnostics. Well played.
I got to say, I think I learned more about Map sensors from your pass couple of videos then I have over the last few years.
Is it really a "Good Morning" when your car won't start and when it does, it pukes out all its transmission fluid? Seems like the ultimate irony!
Will 2025 be the year Ivan treats himself to a 4 post lift??? 2 post... ;-) Love the channel man, really appreciate your technical ability and transparency in your diagnostic approach to the crates people bring/dump on your drive!!
I said the same thing.. He needs to build a separate shop right next to the garage.. At an angle, so that you can still use the same driveway.. And just make it a 3 or 4 car garage -- with a dedicated lift. Leave your old garage for 'parking cars" -- and put all your tools in the new shop. He deserves to have a dedicated shop setup. Make it at least 30 ft deep, so you can have a work bench all along the back wall.. and tool boxes, etc. Depending on how much work you do yourself, you could get it built for 40k to 100k... You could even get fancy and put an apartment above, in the attic.
Ivan said in one of his past vids that a permit would be required for a hoist, and that his homestead couldn't pass for a permit for some reason.
Its 4:56am Here in California. I'm popping some popcorn for this.
On my 99 Trans Am I just put a resistor in line so it always works.
NGL... this episode had me screaming at the screen !
Read the comments.. It had EVERYONE screaming. lol
I'm going to lose my mind watching Ivan slipping that poor transmission over and over again. At least that transmission is rebuildable/replaceable. Should be a 4T80E. And I guess it's possible it was already hurt before Ivan touched it.
Turns out the transmission case was CRACKED!!
So definitely not "rebuildable" 😅
@PineHollowAutoDiagnostics Ah. Well slipping clutches or not it will have needed a new one anyway. It'll be harder to find a junkyard one for this. Also it's a bit of a bear given the size of the transverse engine/trans setup.
@@kevin9c1 no shop in town wanted to touch it...can't blame them haha! Luckily an experienced transmission guru agreed to take on the job 🙂
@@PineHollowAutoDiagnostics There used to be a ton of Northstar/4T80E cars roaming the streets. I don't think it's anything too unusual for any shop that can R&R a transmission.

@@lexmaximaguy8788 Or on the side of the road where the owner probably truth be known found it in the first place!
I definitely wouldn't want to drive it without a manual transmission.
Ivan…I’m only 4:30 into the video….what a great way to DESTROY a customer’s transmission. Just keep on shifting from gear to gear and flooring the accelerator without checking transmission fluid. If you didn’t burn up the pump, the wear you just put on it is unacceptable. I humbly admire your diagnostician skills, but come on brother….apply some common sense in these mechanical situations. There is obviously something wrong…continued revving and shifting is not going to magically fix the problem….good grief! I know it’s not your car, but you should treat it as such.
On edit: @ 5:10 “it’s smoking”…no 💩 Sherlock. @ 5:50 “it needs transmission fluid NOW”….you think?
Dude! NEVER..NEVER..NEVER rev the engine trying to get a vehicle who's transmission wont go into gear because of low fluid to move .. lawd have mercy! Burned up pump...clutch packs..trash afterwards!
@@jameseast4033 actually it was trash BEFORE I even saw the car... So no worries 😉
@@PineHollowAutoDiagnostics Why do I feel like you are trolling us and this should be an April fools video.
Are you you knew the transmission was done before all that reving?
The countdown is a purposeful delay to stall any theft attempts. In different cars, it's also timed differently for some reason. The car will allow you to "attempt" to start it, and if you're unsuccessful after a certain amount of times, it'll shut off attempts. It thinks you're trying to steal the vehicle. There were about 10 different codes GM used in some of these vehicles. The "chip" key designs used in these were a royal pain. Buick was also early in using electronic dashboards, along with certain Oldsmobile models, mainly the Toronado and the Riveria. As to MAP sensors, I've had them go on those years of GM. Almost all others used a vacuum hose with the sensor mounted on the firewall. They had polarized plugs on them so that even though they looked the same, the plugs were different. Electric EGR valves of different designs were also coming out then and they too were a pain. Not very good years for electrical experimentation. Bad years for a lot of cars made back then.
I think Ivan fooled us. He knew all along the transmission was toast, was probably informed by the owner, who wanted him to fix other issues first. So he proceeded to "burn up" the transmission to see what kind of reaction he'd get. Well, it seems he got one!
What makes you think that?
Do you have evidence?
@@wayneessar7489 surely the guy knows better than to try to drive the Caddy like that. WE know better, and we're not mechanics.
@adotintheshark4848 The transmission was not his task, the car was towed and unloaded in his driveway identified as a no start, 9 months at a different repair facility.
He was not taking it for a trip to town but moving it indoors.
You would think the owner or previous shop staff members would have checked and corrected the fluid levels.
@wayneessar7489 but even just to bring the car into the shop like that, you don't " force" it. First thing, you check for fluid. I think Ivan knew all along that car was a " no go" and just wanted to see if the car would actually get to the garage.
VATS system: I bought an 89 Firebird brand new. At 40k miles the security light would illuminate and car wouldn't start. Cycling a couple of times got me home. I found the same wires under the column you did, no key measured. Found one of the wires had broken off at the key tumbler. I owned the car up until 160k miles. The wires would break at roughly every 40 to 50K miles. The wires at the tumbler were so small and got flexed with every key cycle. Poor design.
Ivan, I know you have permitting issues to deal with but you REALLY need a lift if you are going to continue to work on cars.
Believe me, it will further your career because, even though you are young now, your body will catch up to you.
Ask me how I know😊😊
It's not just a lift but a taller building to put it in. Looks like he has plenty of space for a pole barn!
Just getting a workbench would be a great improvement. He uses cardboard boxes on a dirty floor….hmmmm
Boy are you right! I'm 78, and if I was Ivan's age, with his incredible knowledge, I would find a way to build a conditioned three high bay butler building with three
bendpack lifts in it. I'd also build a bed and breakfast right on his land where his clients could stay as he waved his magic wand over their vehicles. Were I him, I would talk to the town muck-e-mucks about the revenue he would bring in to the town. Money Talks.
Eric O would be proud of this comment section, sir! 😁👍
LOL! "THE COMMENT SECTION"!!!
Any clutches remaining in the trans after trying to goose it into the garage?
@@jedclampett6466 sure, engaged just fine after dumping in a gallon of ATF 😂
It was puking it back out about a quart per minute though... What a waste of good ATF 😆
Actually, no that's not how that works, usually what happing to clutch is burn out as they wear out overtime, they get too thin with too much clearance and the piston cannot stay sealed any more or you're not getting enough pressure to apply the pistons There are a few things that can cause this. More than likely they were actually transmission is fine it just needs to have the pump rebuilt but it's all gonna depend on what happened If there is what I think happened then the torque converter seal blew out there's a couple things that can cause this issue
better installing a good old manal 6 speed racing trans,lol😅@@SHSPVR
Say you don’t know anything about transmissions, without actually saying it.
Every Transmission builder on the Planet’s eye’s just popped out of there head and with all those rev’s. You have just cost this customer a Transmission guaranteed all those friction disc’s are fried…..Time for a Rebuild. You should have checked the level before even starting this car…….Pump Seal is blown out. 😳😳🙄🙄
The problem is the transmission is so old, it's really hard to find the parts too - should have treated it with basic respect.
Interior took some cues from Alfa Romeo. Beautiful car with some awesome technology. I don't think the public knew how much engineering was behind this car.
As soon as he tried driving and I knew the trans was probably dry I ran to the comments. 😂😂😂

Ivan,
Thanks for another great year of PHD videos! Looking forward to more great case studies in 2025. Wishing you and your family a Blessed and Happy New Year!
The layers of the onion are unfolding. Those 4T80 transmissions are no fun to replace. I’ve done a few. I place the resistors in the harness right where you did. The pump bushing probably worked its way out and pushed the seal out. Seen it before. I call them “Junkallac”. Great job Ivan!
look inside of the lock cylinder. There are two tabs where the key resistor touches. People push the key too hard and bend them
Add a resistor where the meter is plugged in
Lol Ivan, I was about to leave your video cause I thought it was " a scrap salvage scenerio" but in true PHAD there is still more innings in the game.
So now I am curious how the transmission case got cracked! I have a hate-hate relationship with almost every 4-speed GM front wheel drive transmission...except the 4T80E which were pretty stout.
I'm willing to bet that is why the car got parked many years ago.... Trans was broken and extremely expensive to repair.
Then over the years the map sensor failed, and it turned into a no start at which point it was sold and the new owner had no idea about the underlying trans issue?
@@volvo09watch Part 1 again... Owner said it was driving fine last year, then wouldn't rev after sitting for 4 months at which point he took it to his buddy's shop. After 9 months there, now it doesn't start at all and apparently has a busted transmission... 😮😬

@@Wyllie-x9z what's a common problem? Cracking the case? 😮
trans input shaft leak or torque converter, mine was pouring out the bellhousing aswell, new torque converter and input seals fixed it.
I spent hours to diagnose koeo no blower. Turned out the engine needed to be running. 😂😮
why? Because the module capacitors puked out acid that ate the circuit boards.
Here's and FYI
This issue pertains to The Buick Rivera's of the late 80's early 90"s with the Touch screen Green colored MonoChrome CRT Monitor Screen in the dash EG 1989 Buick Rivera Plus the 1992 Cadilliac STS/CTS with the 4.9 L V8's or 300 CUI V8.
There is other GM Vehicles of the same Era's that use the Passkey Anti Theft system too that are affected as well.
To tell if your GM vehicle has the Anti theft system look at your ignition key for a weird bump/bubble towards the key ring end . In the center of that bump is 2 metalic contacts on each side of the key. This is a Resistor inside the Tumbler there's a sensor in there that contacts those 2 contact points on the key. The sensor is connected to the pats module in the Trunk Mounted to rear of the backseat behind a cover you pull off from inside the trunk.
The theft module has a preset from factory Resistance Value it looks for from the resistor in the key via the sensor in the tumbler.
The issue is its a bad design because there's 2 really thin wires that exit the tumbler that actually move when you turn the key and they get weak and after a while they break and they don't always brake and show visible signs of being broken as they can/will brake with insulation intact which is something to take note of.
I found this out from helping a Relative with his 92 Cadilliac CTS. which left him Stranded thankfully in a Parking Lot and not on the side of the road.
I could see you being an instructor for automotive electrical systems troubleshooting/diagnosis courses. In my opinion you could offer some of the best training out there. Fancy systems are easy to overthink and take a wrong direction, way to go on keeping it simple and zeroing in on the map sensor!
I am really surprised the PCM did not have a default strategy when the MAP was disconnected. Usually a MAP, MAF, TPS etc all have a limp mode to still run the car.
Guess it's wise to carry a spare MAP sensor in the glove box on this beast! 😁👌
Maybe a spare Toyota to get you home when it dies
So essentially this is a "cliff hanger" video?? Good job on that, and have a happy new year!!🎉
We really didn't want it to be over, did we? Haha
I'd still like to know why the strut towers are teal green. Did Pininfarina ship them all that way?
Great job, Ivan. Happy new year.
Interesting that they sent the car to you knowing it bleeds trans fluid. They should have mentioned that to you. Interesting the MAP was toasted like a hot dog in that cavity.
Based on the evidence from past work and modules galore, electrical clusters and so forth...I doubt working any further on this car is going to be worth the time. Unless the customer has said he was done with the other shops and his plans were to get the car into completely normal operation and functions, I'd pass working on it due to parts availability. As long as the owner is going to pay for the labor its going to take just to diagnose this pig, it will make money but I'd want to be sure the owner isn't going to call it quits half way into spending much money.
Time for the owner to punt this car.
An Allante' enthusiast with knowledge, experience and needed resources would love this very low mileage, rare gem.

I'm afraid he still doesn't know what he did wrong.. oof
@@jimr549 ok boomer
Def not original key. It has a GM logo on it. Cadillacs all have keys with a caddy symbol on them. Cadillacs are status symbols and even need to show that status when you throw your keys on a table somewhere. Being a GM key they have 15 different pellet resistor sizes. Key value 14 is 9540 ohms. In pro demand it shows 15 different keys for the Allante as well. Doesnt make sense that the amount of resistance to make it start falls between #13 and 14. Ive bypassed several of these but i add a toggle switch inline so customer can still disable the ignition and at least slow someone down trying to steal it. Forgot to add i reallty did not think map would fix it. Thought they had a default parameter to use when faults were detected. Figured unplugged would run on a default value. Learned something today.
Good info, sir!
Fluid was exiting way too fast for a seal failure. Think main seal on the engine. The input seal does not hold pressure. The large stream suggested a breached fluid passage or cooler line.
Love the 14 yrs expired PennDOT inspection sticker! If I'm not mistaken, Eric O. had a pretty good work around/hack for that pass key system a couple yrs back (I may very well be thinking of a different generation, though. Not sure.)
I think you could rebuild / improve the HVAC Power Module over the factory version and the Rock Auto version. You would need to measure the characteristics of the cooling fan; current at voltage, resistance, inductance, etc. and take apart the original bad unit to see how it is packed / designed. If the unit is not potted than the repair / upgrade could be a simple output power switch replacement. I say this because automotive power device design has improved greatly from when the car was originally sold.
What do we know from the Rock Auto replacement HVAC Power Module:
The output power switch is a Bipolar Junction Silicon Transistor 2N5684G PNP 50 Amp 60-80V 300W in a TO-3 Power Package from ON Semiconductor. Being the output power switch is PNP we know that the fan motor switching power amplifier drive is high side, just like the wiring diagram indicated. When the fan is commanded full on the module will probably dissipate around 13 Watts of power, which is a lot for a high side power switch. With a smart high side automotive driver, depending on the switching frequency you could probably get this down to 2 Watts or lower, and have many more protection features than the 2N5684G.
It blows my mind that a mechanic would keep trying to move this car without immediately checking trans fluid at the first signs the trans wasn't engaging properly.🤯🤯
@@jeffs2809 I just wanted to move it to a flat spot to do a proper fluid level check 😜
@@jeffs2809 it needs warming up first 😆
Yes that may be exactly what blew out the front seal? Low fluid, and reving it up like that. Car's sit a long time, you better check for tranny fluid when it doesn't want to move? It was probably going bad, even before sitting. Poor Ivan! He did a good job on bypassing the key reader module.
If the trans wasn’t totally spanked before, it is now.
@@MichaelMosesHammer so why did it have ZERO fluid to begin with? 😉
This car went from a snowflake to a damn avalanche real quick lol 😂
Some fire starter and a box of matches will fix that thing up really quick 🔥🔥💥 What a nightmare that car is .... Happy New Year's Eve Ivan and to all of the YT community😊
I wonder how many years its actually sat ? Hardened trans seal ?
The 4T80E front wheel drive Transmission can be rebuilt if you can source parts such a new oil pump for it.
Richard Crich of Precision Transmissions ln Amarillo Texas is a good person to talk to about rebuilding the transmission but you would have to tow it for 1 day from State College in the U.S to get there !.
Good tip, friend!!!
Mr. John O. Grettenberger passed away in 2020............
Usually, what happens is the contacts in the switch fail. My son, who is an automotive locksmith, uses the resistor module in a spare key, solders leads to each side, then cuts the two wires going to switch and inserts the resistor module. The security system is now forever happy.
Car is in great shape. I hope it is saved and gets back on the road.
That thing is a PITA & if you remember I asked the rhetorical question why transverse engine mount for the obvious reason of transmission mounting would have been able to put a known more robust one inline to a rear wheel drive kudos for all the effort to even get that PIG to start & run.Also someone must have known about the trans can not believe that it failed just sitting around for how ever it did.Cheers Ivan you win more than you lose.😂
Wiring a resistor in place of the key was the way to bypass the pass lock when installing an after market remote starter. The pass lock module will relearn the new resistance value after 10 minutes.
This is Vatts which the voltage value is a non relearnable hard coded into the module. It is one of 15 different values. You are thinking about Passlock1 in which a magnet in the lock cylinder rotates past a hall effect sensor pulling down the 5V from the BCM into a value. This value can be relearned after 10 minutes with key on after start fail.
Mornin Ivan. Glad you got posted in time for my coffee. ;)
As soon as he tried driving and I knew the trans was probably dry I ran to the comments. 😂😂😂
Yep Ivan, you bought this customer a transmission!!!!
Smart to leave transmission issues to someone else. Too many parts if you need to rebuild it. For those of you who do, you guys played with too many rubics cubes growing up
All the internet expert warriors saying about the theft system in the last 2 episodes as if Ivan's some sort of complete dunderhead.......Careful people they walk amongst us!
I was one of them and glad to be proved wrong. Does make you wonder though what the Anti-theft system does?
The car had a theft system problem , that had a bypass box done prior that still kept the antitheft light on. This was not known or looked into until after the MAP sensor problem was discovered. The original antitheft module, if not bypassed, would have prevented the car from cranking and running. In the end there was nothing wrong with the original antitheft module ,but there was a problem with the key pellet reader in the ignition switch. Adding the correct resistance, as a substitute fixed that very real problem. This antitheft , aka VATS, Passkey etc, has driven people crazy since about 1986 on the Corvette.
@danieljurgill1681 exactly! unless Ivan knew it had been bypassed and forgot to tell us? I did ask if it had been bypassed in the previous video.
@ohboy2118 it clearly has issues but hey 30 years old! Didn't appear to be the reason for not starting
@@danieljurgill1681💯
Just read up about the Allanté, what a crazy production process.
I think it's a cool looking car but damn it was expensive but not surprising as the production costs must of been through the roof.
What is wrong with people? How the hell is Ivan supposed to know that transmission was cracked and leaked out? The car was brought to him for a no start problem and not a transmission problem. He's not psychic, how was he supposed to know?
Classic’ “ in one end out the other “ fluid top up 😳🤣
I was screaming at the screen when you were trying to make that car move. Not sure if you did it any good.
Seeing that transmission puking ATF fluid reminds me of our 97 Taurus...it had a huge crack in the case. When i drove it at hiway speed the torque converter would lock up and it drove OK, but once speed was reduced, it barely moved. Is why i will never own another Ford.
What other car brands have stronger transmission housings?
@wayneessar7489 never seen this issue with 4 toyotas so far.
@mikefoehr235 Very good..!
Love your diagnostics but Was cringing the whole time trying to drive it. Ida checked fluid immediately once i realized it wasn’t moving or moving well. Sounds like trans was broken already…needed a case?
If that transmission is a 440 and it really is the input seal, the input shaft bushing is wasted. Needs a torque converter, seal and new bushing. In some cases, metal fragment damge also. Replace transmission. GM T.S.B
The Transmission is a 4T80-E.
Transmission cracked.
Always check fluid levels before operation at least that's recommended by the manufacturer.
The owner was lucky to find someone to work on this dinosaur lol I’ll doubt there’s a factory service manual that’s even available for it!! GM sent them to us before the cars were even delivered as well as any special tools needed to work on them. I did a PDI on a new Allante!! Great video Ivan !!!!
ALLDATA has most of the original GM shop manual information for the vehicle. I think for this vehicle the complete printed version of shop manuals includes the manual Ivan has and a Electrical Diagnosis Service Manual Supplement.
Broken wires inside the tilt column is probably at fault causing theft deterrent. The a/c heater control modules were a problem since day one. Trans front pump seal is old and cracked and leaking. Welcome to Cadillac's money pit car!
Wow! Ivan, I cannot believe what you did to that transmission! Smoked it! You even said that the fluid needed to be checked after you rev'd it to the moon, in forward and reverse a bunch of times. Did you check it? No! You just kept reving it until it moved a bit down the lane and really started smoking with no further movement. Then, you check the fluid level to find a dry stick. You checked the engine oil at that point as well. This all goes against your typical M O of checking all fluids before starting and driving a vehicle brought to you. How is the coolant level? Did you check that?
In my opinion, you owe the owner transmission service to replace all affected friction components that are very likely damaged by your irresponsible actions.
What the heck was that, a momentary loss of consciousness? You are better than that. Or at least you were.
The transmission case was cracked. I’m betting he already knew that before revving it up. Makes for lots of comments.
@@douganderson7251 No. How would he have known the tranny had a crack in it? He would have stated so if he'd discovered it. He was surprised by the fact that the car wasn't moving in any gear. Plus, crack or no crack, wisdom dictates that you ought not to try to drive a car that is out of tranny fluid. Besides, us viewers don't know for a fact that the tranny has a crack in it.
UPDATE: For everyone down here jumpng down Ivans neck about him supposedly breaking the transmission, see the first comment here in the comments. Ivan states that a large crack was later discovered in the transmission housing. Eeeeeeeeveryone take a deep breath and eeeeeease back a bit.
Ivan didn't know this before he raced the engine.
You gotta give it to that owner man,,, he is an eternal optimistic !! lol
It'll eventually come up in value. Eventually. Right now they are really cheap. But you are screwed if there's any interior damage or exterior trim damage. All unobtainanium. I wouldn't even consider a Northstar one like this one. Add all the nightmares plus all early Northstar issues.
Oh my goodness. Where do these vehicles come from---where's my aspirin- This makes the Transit connect look like a cake walk.
Two nightmares back to back, keep the adventures coming in the new year.
Im surprised all of those modules work as old they are. Capacitors like to dry up and such.
