Nissan fried tcm no start issue

- Опубликовано: 11 апр 2013
- 2007 nissan pathfinder does not start, pulled codes, found p0717, trans circuit a signal, and u1000, network com circuit, codes. Blown tcm fuse, coolant mixed with transmission fluid. Fried tcm...
UPDATE I made this video before the NISSAN TSB was issued to my software. The real issue was defective radiator/trans coolers. Bypass the radiator and install an external trans cooler to avoid this problem. You might get lucky if you flush out all the old coolant with simple green and the old atf several times to eliminate the water shorting the tcm. but more than likely you will need to replace the tcm or possibly replace the transmission. sorry for the confusion, as i didnt see the tsb prior to this, and I diagnosed it on my own without outside prior experience for this case. I did see similar failures due to neglected, rusted or corroded cooling systems before with bmw, and gm vehicles ect... in the past. thank you for watching*
Do me a solid if this helped, and follow me on instagram.

Folks it’s a known issue of that particular transmission made by nissan.. once trans is replace, i recommend ya’ll to bypass the radiator and install an external cooler for the trans.. that way you dont worry about it happening ever again.. it’s a good transmission, it’s just a bad radiator design by nissan. Trans fluid and coolant mixes up and when that happen it ruins the tcm module inside the transmission.

That actually happens if you change the coolant or not, changing your coolant has nothing to do with it. The poor design of the transmission cooler is the actual reason, which has absolutely nothing to do with changing our coolant. I am dealing with this problem now, and all maintenance was done at the stealership. So your theory of "this is what happens when you do not change your coolant" is like Swiss cheese.
i work on all makes and models. ive seen this happen with corrosion in vw, porsche, audi, bmw, toyota, pontiac, buick, etc. first time on a nissan. so i assumed it was from previous experience. apparently not. but oh well. video is already published
I give you props for acknowledging the statement from George, which is correct. This issue with Pathfinders and Xterras plagues soo many owners. The easiest solution is to detect it early and bypass the tran fluid to water circuit. The trucks already have a independent air to liquid cooler for the tranny. The cooler is used primarily to help the transmission get up to operating temp.
Exactly!
The mechanic is right and so are you.. coolant over a long period of time can become corrosive due to electrolysis...
i know im asking the wrong place but does any of you know a method to get back into an instagram account..?
I was stupid lost my account password. I would love any help you can offer me.
Exactly, you guys are right, the issue is not the coolant, is the faulty radiator in all of this vehicles!!
Well, followed your instructions and found the exact fuse issue. :) Thanks sooooo much. Awesome stuff...
Hey, I think your right and i agree. But at the same time, I know almost every other car out there has problems big and small. In hindsight I have taken measures with my own personal cars to prevent issues. I find major problems others are having and keep it from happening, or at least try my best. There are thousands of people dealing with this, and even more dealing with blown motors from direct injection engines. BMW, Vw, Audi, ford, Mazda, Lexus, all have major issues causing engine and trans failures. Many not covered because past warranty. If I owned a nissan with this issue and it blew on me i would buy a used trans, do the external cooler mod and call it a day. Of course keep an eye on recalls but what can u do....? Learn and don't make same mistake and hope for the best. Thanks for the comments!
that happened to me today. My truck suddenly stopped in the middle of me driving it. Then it started again after a few attempts and all my dash lights started flickering. The forums for Titans helped me solve my problem. I went to Nissan and bought the ECM relay replacement fuse. In my case it was colored green and second from left relay. Come to find out that a while back there was a recall and ECM relay is the common culprit of said symptoms. Took me 5 minutes to install and solved my problem at least for now.
Nissan has a recall on thier froniter, pathfinders etc. The radiator mixes in with tranny fluid at one point. It does'nt always happens but when it does it is expensive fix. What I did to my frontier was unplug tranny cooler lines that run to radiator and bypass them to a air cooler that is already installed in front of your vehicle. Looks like a radiator only smaller and holds no water. Thus that is why it is called air cooler. Have heard many stories of nissan owners try to have dealership pay for fix but dealership says it is not thier fault or some bull like that. Thanks for the video!
Did the bypass myself with no ill effects 6 months ago. However, the problem is not a recall by Nissan even though it should be.
11:30 at night. After I seen this video and after attempting checking everything in my arsenal. I could not resist but to check this 10 amp fuse. IT WAS THE SAME ISSUE. Mind blown and happy that i don't have to spend money to have someone do a diagnostics on it.
Thanks man! Made my diagnosis very simple as it was identical to yours 😁
From all I've read, this has little or nothing to do with changing your coolant. One of the two transmission coolers runs through the bottom of the radiator and is prone to leaking. THAT allows transmission oil to mix with coolant and vice-versa. It is a factory defect. It can be avoided by bypassing the internal transmission cooler with a simple hose swap.
Happened on my 350z cost 4k to fix not a good day
Feb20,2018. Had a 2008 pathfinder hauled in shop from out of State auction. No crank. No communication. Previous mechanic from GA had severely molested fuse box,ecm, ignition wires under dash. After repairing all wiring, jumping starter over by screwdriver 🤣, it would not crank. Had to jump the ignition relay (bottom 2 terminals) then it would crank by key but not run. I did check radiator and it was milky. (Thanks to this video!!!)Who knew to check this for a tcm failure to cause no communication to ecm, a solid dash light immobilizer condition. I greatly appreciate this video, I was thinking ecm was root of the problem and apparently previous GA mechanic did too, I could only imagine how many hours spent on this turd. Still not sure I have correct key, only 1 and it is USA(walmart key?), not Nissan. All other keys and fob are mia.
Thank you for the info , what I’m having trouble diagnosing is the coolant under the fuse box not sure how it got there
if your money is tight you can try this (only if your transmission still works when you install a fuse), bypass the radiator and run only to external cooler, try drain and fill with new filter a couple times. and install new fuse, clear codes in transmission. if that doesn't work, install used, or rebuilt trans. it has to get reflashed by dealer or shop with good scanner. hardest part is getting all the oil out of the coolant!
I am just wondering what’s the connection for not changing coolant then mix with transmission fluid. The reason is the the transmission cooler system is connected to the radiator for cooling purposes. Somehow the transmission cooler get hole then the coolant get into the transmission line. Change the coolant or not, if the Transmission cooler get hole, then still coolant and. Fluid can mix together.
Omg. U a life saver bro. I thought my starter was bad and bought a new one and it still wouldn't start. Stumbled across ur vid here and checked that 10amp fuse and wala, cranked right up!!! Another thing tho, I pulled the rad cap off and I don't see anything fluid at all would that cause any fuse popping issues??
Keep the videos coming! Transmission issue”” it’s a Nissan!!
Well documented issue with the VQ from Nissan....
We call it the strawberry milkshake of death(SMOD)
Anything 2010 and back will need an updated radiator and trans cooler.
good video first off . We have a 2014 nissan sentra that came in with a no start issue with new battery and full charge , im new to nissans tech and mostly work on diesels , what we are seeing is the car is not responding to the ignition switch/key , put the key in it chimes but nothing else happens when switch is turned on all directions , no dash /cluster power up , nothing happens other than the chime saying the key is in ignition. headlamps work, door locks work, but nothing else like the key is not being used at all ? scanned with multiple scan tools , Matco Maxme , and others , coming back with nothing other than a B210B code ? there is little to no info on Nissans doing this , we replaced the ignition switch with no change still acting as it the key is not being used , its a regular style key not push button start and we have both keys from factory . trying to help this custmer get back on the road but we are stuck . anyone seen a issue like this on 2014 Sentras or any latermodel nissans ? again new battery with 13v , put key in ignition and turn with nothing happening like no one is trying to start the car ? Thanks for any help in advance guys !
Great video, very helpful (yes, I read the comments and it's a known defect in Nissans). I came here because my 2009 KIa Sedona is experiencing the exact same symptoms as you described (and as others described in the comments; no crank, no start... jumped car to live with starter relay, transmission stuck in 3rd), but I pulled the code P0890. I checked all fuses with multimeter and they are all OK.
a u1000 and p0171 are not things you can buy, They are diagnostic troublecodes, u1000 is a universal DTC that basically means there are certain modules on the CAN BUS that are not communicating
Im a nissan tech. I have 2007 xterra. This is the funny part. The problem existed as a no start. Turned the key on no SES light no door open light, no wiper operation other than rear, headlights stays on, cooling fan on, and no key chime from instrument cluster. Used Consult scanner no bcm shows up U1000, pcm back up code cant remember code. Check everything, started unplugging the ABS, TCM AND ECM. Chimeing came back on. Plugged ECM back in and flipped key SES AND ETC SHOW BACK UP. RECONNECTED ABS AND LAST THE TCM. TCM had caused the CAN system to shut down do to a shortage in the transmission valve body. Left the TCM unplugged jumped the starter circuits car started and ran. This a future tips just incase u run into a problem like that.
thanks for the tips, in this case the tcm had a code, forgot what it was now, been some time.... i simply cleared code, installed fuse, started it up. i believe you. i sure hope i dont get too many more if these. such a pain to clean the cooling sytem. gotta use simple green
yeah they are cleaning everything up ughh. I hate it. Nissan knew better.
I have a 05 titan and twice now I have got in it to start it and it had no power to nothing and key wouldnt ccome out ignition...so I hooked jymper cables up to it and nothing .. battery only been in it a week..I undone hot cable for about min half and it started right up and was fine then a day later it ddone it again exceot taking hot cable off didnt work tried few times ..well I was like let me undo neg side see what happens wekk it started and has done fine..what be the start of this problem one person told me it was my security system and probably need be looking for a computer..was just wondering if anyone has any insight on this or point me in right direction...thank u in advance
I would say make sure th terminals on the battery +and- is not corroded badly and no blown fuses on that cable. If it was your security system it would show up a red light on solid with a key in it, on the dash. If would either not start at all or just turn over and not fire off like it show with the theft system.
Hey help. I have a 07 pathfinder and had issues with it recently. One night my girl was driving it to work & she said it felt like it was loss of power but over working itself. Later that day when she got back into the car, it wouldn't start. After looking around I found that the tcm fuse blew and would blow every time I would try to start it and then run in limp mode I believe. Anyways, I looked around some more and assumed it to be the "valve body" At this point it's already at the Nissan dealer get looked over. They wanted to try and get me for a new tranny($7k) after looking around some more I was still hooked on it being the valve body and suggested that they change that. Anyways, they said they changed and charged me 2100.00 for new valve body, pan gasket and atf. When I got home I looked where the valve body would go and it didn't appear to have been touched in that area. My question is, could they fix that fuse popping issue with out replacing the valve body?
how can it be fixed subtle driver?thanks a lot.
In 1:00 I do have an issue with that blue fuse the one carry 3 pole. As soon as I remove it my draw goes down from 0.08 to 0.03 ! The u know what that fuse control exactly
How can not changing your fluid make it mix with your transmission fluid and blow your module or whatever you said can you explain that for me please
I have a 2003 Micra and think this has happened to it. It makes sense because I've never changed the coolant. Will a new starter motor, which has been proposed, correct the problem?
I'm having this problem but my coolant looks OK my issues started after changing a tail lamp fuse
Hi my Nissan Latio can't start then keep cranking sound. The dashboard also flashing the key in the vehicle, I found the fuse box no53 EGI A20 fuse r burn, so I change it but still burn everytime. What can I do?
I experienced the same codes on a Juke....found the alternator was making just enough voltage to turn the "battery box light", but not enough to run the transmission electronics. May want to check that if his video doesn't work out in your issue
The problem here is the radiator is busted on the transmission cooler coil inside the radiator causing the coolant to get into the transmission oil. This is a factory defect and there is a lawsuit ABOUT this issue, you can Google defective radiator Nissan and read about this issue. It happened go me, and what I did to fix it was, get an after market radiator from auto zone, and then I flushed the transmission with clean fluid , by leaving the return hose off the radiator and catching the fluid in an separate container I started the engine and as the transmission pump pumped the old oil out I continued to pour new oil in until the oil coming out was clear, then I had my help go thru the gears as I continued to pour in New oil until the transmission oil was coming out clear, now that the transmission is flushed, I the removed the valve body out and completely dismantled it, and cleaned it wd40. I also dismantled the computer and cleaned it with wd40, the computer is the flat looking black box that is on the valve body, I also checked the solenoids for proper continuity ad change 2 of them, can't buy them new, had to go to a transmission shop and the man sold me some old ones. Put it all back together and it worked fine.
did you read the description? thanks for the comment!
Please my nissan navara 2012 is not start I notice that the light is not show on the glow plug what can I do
HELP!! I have a 2007 Nissan Pathfinder and Ive had the TCM replaced twiced. The first time in late december 2014 and again October 2015; there was a warranty on the tcm. And now my nissan has died again; Im assuming from the same thing based on the same symptoms that happened the last two times, before it stopped working. I did noticed my coolant was less than normal and I noticed moisture or a leak under the radiator. Im at a lost on what to do. Ive paid just under $2000 for repairs and im still owe $11,000 (loan) on this vehicle. Im considering voluntary repo. I cant trade it in; the value about $2000. Would replacing the radiator help? Any suggestions anyone??
Great video !!Do you happen to know the location of the transfer case control module on the Nissan pathfinder 2007 ?
2006 pathfinder with p0615
Starter circuit failure. All testing leads to tcm issue. No coolant contamination though. Anyone had this code and replaced tcm assembly with valve body?
after changing the transmission. the refrigerant and the fuse that follows. I changed everything and my truck said that it does not have communication with the can line. What can be ?
Nice find sir,just subbed
It isn't because they didn't change there fluid it is a factory defect in the radiator that causes the fluids to mix. there is a law suit against nissan for this. Call nissan consumer affairs. The same thing happened to my 2007 frontier.
your right! i made the video before i saw the bulletins.
+subtledriver. Mine is doing everything to the t that u were saying..I'm going to check that fuse..I have did 2 tranny flushes but don't know if I can save it. It only acts up when you floor it and it acts like it shifts done 2 gears and has a real hard shift.
chad pollaski
mine does the same :(
So to prevent this from happening I would have to replace my radiator?
@@TallVictorandmrgrimm1211 depending on the year of your truck it may not be a concern for you. If your truck was made after 2010, this problem was already fixed. If it was made before then the recommended fix is to replace the radiator. You can also simply swap a few of the lines around so that the transmission fluid no longer runs through the radiator and only through the separate transmission cooler. Bypassing the radiator will cause your transmission to take longer to warm up as the radiator actually helps to warm the transmission from cold since the engine coolant heats up faster and it will also reduce the overall cooling capability so it may not be ideal especially if you live in a cold climate and/or tow with your truck. If you have a truck from before 2010 and can't replace the radiator right away, I would recommend doing the bypass at least temporarily until you can replace the radiator. You can find more information on how to bypass the radiator if you search "Nissan Frontier bypass". This is the same for the Nissan Frontier, Xterra, Pathfinder, and I believe also applies to the Titan and Armada. The affected years may be different for different models.
So there's no way to start the car and make the engine run until we replace the module or the transmission ??
I have a problem exactly same with this so do I have to rebuilt the transmition or just go to the dealer and buy u1000 and p0717?
Hey i have a 06 pathfinder and the truck no sign of starting or cranking also the reverse lights are on while still in park. The codes on scan tool are u1000, p2101, p0462. Wht could be the issue buddy?
MY 92 Pathfinder cranks but don't start it has good fuel pressure I think the timing is good I got Spark I got to check if it's the right color though and it turns over in like different different pattern rev rev Rev rev room rev rev rev rev room I tried to to spell out the noise LOL what can I have going on here my distributor should be good a mass air flow sensor replaced and I'm getting code 5 5 off my computer which is no malfunction what do I do
2008 Pathfinder came in my shop today. Exactly the same issue...
henry huy hoang what was the solution cause this in here doesn’t add up... there is CVT and coolant mix in the transmission...
after changing the transmission. the refrigerant and the fuse that follows. I changed everything and my truck said that it does not have communication with the can line. What can be ?
Could you post the part number?
This has nothing to do with changing the coolant. The cooler/radiator break and internally and intermix causing issue. Very common on the older pathfinders/frontiers/xterras
Does anybody know if this same issue could cause crank but no start with the U1000? Already tested swapped relays for IPDM, changed fuel pump and it started but then did it again. Seems somewhat intermittent, but mostly crank with no start.
Did you ever figure out what was wrong with it? I have a 2005 Armada with a crank no start. After cranking for several seconds it smells of gas in the engine bay but I don't have any fuel rail pressure. . I desperately need help figuring out what is going on. Checked all fuses and every thing is good.
What’s the coolant have to do with that... it’s the radiator that’s bad!!!
how is the frequent changes of coolant will prevent it from getting into transmission??
It Does not, transmission heat exchangers are failing and exchanging fluids with coolant/tranmission ....
mixing different coolants will cause same problem. alway have to use exact same coolant and not the universal called for any make yr and model, or mixing orange with green coolant etc.
I have a 2000 Nissan xterra that won't start. The a/t cont fuse is blown and every time I put a new fuse soon as I turn key it blows. any idea. and all my fluids are good
shane morgan same thing for me. I’ll have to take it in
quick question I have a 2007 Xterra I have the same problem but my TCM fuse isn't blown does that mean my TCM is still good ? I bought everything else brand new haven't done the work yet.
..
u1000 nissan micra what find
I think there is some bad information here
How much does the TCM costs?
Can you fill the coolant reservoir thru the Shift knob?
hahahaah! pretty much! joking aside, i don't recommend it! haha
My 06 Pathfinder has the same issue. Whats the best and cheaper fix?
So how is it the not replacing the coolant damages the computer? Is it thru a broken line? And not replacing it does what and how?. Thanks
Recently purchased 06 pathfinder. Wouldn't ya know shortly after i got smod. I wish i knew about this sooner or happened a little later. It coumd have been avoided. 5k to repair. Dealer estimate was 7500
Sorry man!
Hey there my name is Lupe have 2008 nissan altima coupe 2.5S 4cyl. 2 month ago I had my CVT transmission REPLACED. When I got it back it would stall before picking up speed. Took it back and mechanic kept it for 3 weeks got it back and he said it was a sensor and the main computer. Got it back 2 weeks ago and it drove great for 4 days. One morning while warming it up I drove about 2 miles noticed car was overheating so I pulled over to gas station and left car on and added water. Radiator kept shooting water out so I turned off car and called 3 AAA. NEXT DAY CAR WILL NOT START OR CRANK. SO I CHANGED STARTER AND BOUGHT NEW BATTERY AND REPLACED SPARK PLUGS BECAUSE WHEN CHECKING SPARK PLUGS THEY WERE FLOODED WITH OIL. AFTER REPLACING ALL THESE PARTS THE CAR STILL WILL NOT START BUT IT CRANKS AND THE CRANK STAYS STUCK. A MECHANIC CAME BYE AND TOLD ME THAT THERE WAS NO COMPRESSION. THAT IT WAS MY ENGINE BLOCK. WHAT DO YOU THINK
can some help
I just did the Mod on an 06 that only had 37k miles. Thanks God the coolant didn't have the SMOD "Strawberry Milkshake Of Death"
The problem isn't the Coolant or any coolant for that matter. The problem is Corporations being Cheap and wanting to use the same Radiator to Kool the Engine and Tranny, Once something goes wrong internally of the Radiator, like a Crack and Transmission Fluid and Coolant Mix, that's where the problem lies.
Car Manufactures know this can happen, but they know it will most likely happen after it's out of warranty. That's pretty shady on their part, because they are purposely knowingly allowing this to happen down the road instead of avoiding it with a Sperate Transmission Cooler 🤷🏻♂️
Luckily for me, I used the additional transmission cooler the Frontier has, which as made for when towing and extra cooler to keep the towing heat down.
I don't tow anything big or for long periods. if I do, I'll be sure to get a Separate cooler from the one already on the Nissan Frontier. 🤷🏻♂️
Hey so I had that milky fluid a couple months ago I fixed the issue now 2 months later the car won't start. Saw your video and I have the same fuse burned. I changed the fuse and it started, Should i change the TCM now? how much work is involved in that?
the module is shorted or damaged internally from the h20 contamination. it is unlikely you will be able to clear all the coolant out of the transmission system. but if you can, you might get lucky. (fuse only) but 90% of the time, the damage is enough to cause permanent damage to the module, and clog up the trans badly.
Q? I got a 2008 nissan xtrra. It has code u1000. And i have the snapon solus ultra. I can not communicate with the engine. The car cranks fine but will not start. It came in for a corroded battery terminal. I replaced it with oem terminal and new battery installed. All the fuses are good. Also when cranking all the lights on the dash stay on. Except the MIL.
The MIL will not come on and no communications with the ECM. I checked the powers and grounds that goes in to the ecm. They are all good. Trans is good. Coolant is good. Not like what your showing here on the video. I also scaned all the modules and they all have the code u1000.
Do u have any clue what it can be or have u seen some thing like this.
do you have power directly to the ecu pins, or did you just test the fuses?
I have the same problem but cannot communicate with any modules so there is no trouble codes.
SMOD!!! (strawberry milkshake of death)
Thanks for this tip! Curious, do you think the coolant got into the tcm? or rather the trans solenoid shorted out thus blowing the TCM?
Hello, can you please Help before I go to dealer... my truck turns over fine but its not getting fuel...could it be ipdm?
check for fuel pump fuse, then check crank position sensor function with scanner or see if there is spark. fuel pump needs cps to work.
This one had bad radiator messed the trans,other nissan most have cvt trans problem
Wowww auuuchh
Is the Intelligent power distribution module the same thing as the fuse/relay box?
Yes the IPDM is the white box holding all the fuses . Pretty much controls all the signals sent to ecm itself . The ipdm/ ecm relay is the TSB relay, and its the second relay on the bottom going left to right. Usually the main cause . Or the starter relay which is the the top left relay. Top right relay is your ignition which also has an additional 10amp fuse under the smaller fuse box just before that box. Those are the main ones to really ever have to focus on ever , or its pretty much getting another Ipdm/ bcm which are quite pricy still , but not the 1,100 they used to be. Just be sure to match the part number that is on the one you have .
@@air1forcegrant1 u don’t need to program it so I can just switch it off ? With new one ?
@@coldproductions8404 no u will not need to program anything or have an issues as long as you get one that has the same part # as yours or in some cases they offer upgraded version that have such failures fixed or patched, those will have different part # and will need a program by oem. But if you get same exact part # as you have , nothing more is needed . It works well plug and play.
I have a problem with a titan no communication with the pcm and fan stays on.
Any Idea?
I have the same problem with a pathfinder 2005. Immobilizer stays engaged. Cranks but no start. I can disconnect battery and wait and start randomly. When running tachometer glitches out. Haven't figured it out yet. Can stays on when immobilizer is engaged and won't start. Anyone figure this out yet?
Hey, did you fix the problem with your titan? If so what was the issue. I'm having same problem.
Thanks
Did yall guys ever figured this out? Having the same problem
Frontier has the same problem. Seen it a lot. It’s a bad design in the radiator
I'm sure you are a fine mechanic but that is a known problem with Nissans the owners neglect more than likely had nothing to do with it. As far as I'm concerned it is a manufacturer's defect a class action lawsuit was filed and won by Nissan owners.
this nissan owners won $500 . They settled bit didn't give you enough to cover $5k you just spent.
I have a 2005 Nissan Pathfinder / VQ40DE / and it start but in a few seconds its turn off please help me :(((((((
Camshaft position sensor bank 1
You my friend have milkshake
That's what happens when the transmission cooler fails due to poor design feature. The best thing is to install an external independent transmission oil cooler that is separate from the radiator.
How do you fix it. And how much?? Having this issue with my car
new radiator, external trans cooler, new transmission control module. flush radiator fluid. needs to be adapted by dealer or shop with those capabilities.
This is NOT caused by failure to replace coolant... this is a known issue of older pathfinder that suffered from a radiator defect allowing coolant and the transmission fluid (cooled by same rad) to mix...
I'm guessing you jumped the gun before reading the description.
I found this issue before it was common knowledge. BEFORE YOU COULD GOOGLE IT. I've seen dozens of cases where lack of coolant changes causes this issue in many makes and models. So it was my first assumption. prognosis still stands.
subtledriver fair enough, I did jump the gun and should not have. My fault
So how do u fix it
maybe he just change the coolant 😂😂😂😂😂😂
Oh, I almost forgot. Once all the repairs are done, the vehicle will then have to be towed to the nissan dealer for a TCM flash. (if the repair shop does not have the programming equipment to do it themselves.)
thanks for the comment, please read the description. this video was filmed before the tsb was available and it was the first of its kind. ive seen this failure due to neglect dozens of times before on different makes and models. thanks!
it also happens when people mixed coolants, they become acid and start eating the metal inside the radiator transmission cooler
mine stalls when I turn on the ac
clean throttle body. then check compressor for damage.
It's not from not changing coolant it's from a radiator defect allowing cooling into transmission
With all due respect, this issue has NOTHING to do with changing the coolant regularly. It's a well known defect in the radiator that Nissan has issued a recall for, but unfortunately capped it at 100,000 miles, so a lot of people have had to spend thousands of dollars fixing an issue that was caused by Nissan. The radiator's transmission fluid cooling lines separates and allows coolant to seep into transmission fluid, and since the control unit and many of the electronics are inside the transmission, they are ruined. It's a really poor design putting those things inside the transmission as well.
rzander01 thanks for the comment brotha, I did discover this before it was a recall issue or a tsb. please read my description above. thank you again for clearing this up, but now that everyone can Google it (I didn't have that option since it wasn't widely known yet when I made this) I based it off my previous transmission failure experience from a half dozen other manufacturers. usually it involved lack of coolant changes or just water. again thank you!
this issue caused so much trouble in my life. i couldnt afford to pay 7000 to fix the transmission so they repoed the vehicle and ruined my credit at one point. nissan refused to help at all because it had a 120000 miles on it.
Bobby waters
same here im having alote of problems with my pathfinder.
So I have. A 2004. And to avoid all that all i did was ran a wire to the battery connected it to a push button and connected push button to starter wire in fuse box which should be white with red stripe and by passed the board. So car starts with push button when ignition is open kind of like a kill switch. So no one can steal my truck
Poor design by the Radiator manufacturer. Was the radiator an OEM part or aftermarket?
OEM. It has happened to hundreds of owners.
Those years had a bad trans cooler that would leak trans fluid into the radiator
Nothing to do with changing the fluid
MY SON VEHICLE 2007 WE FIXT CHANGE BAT CABLES, AND NEW STARTE,;...FIRST START GOT BURN UP, SECONDSAME BURN UP, THE THIRD STILL WAITING EXPERT CAME TO HELP, ...THE PROBLEM WAS MY SON TURN TO TIEHGT ,NOW IS WORKING HIS VEICLE. (NISSAN PAT FINDER 2007)
There is no recall on the radiator or or the transmission it is a known fact that the cooler inside the radiator will crack and mix with the transmission fluid has nothing to do with not changing your coolant that's a pretty lame way to sell coolant service. The cheapest solution before this happens is to install an external oil cooler
you are the 30th person to say that, that has not read the description under the video. Thanks for the comment!
I solved that issue by lifting the radiator cap off the radiator and rolling another car under there
So how do you fix the issue
Try replacing radiator, and do a few transmission flushes to get all the moisture out. If that doesn't work, new transmission computer and or transmission replacement.
@@subtledriver I replaced ipdm and ecu but no start. Is there a security mobilizer that's preventing me from starting. I also don't see the letters on dash for PRND. I appreciate your help
@@zoeandaria7724 did you flush the transmission first? If you have any moisture, it will pop the fuse again. You probably need to have dealer reprogram the new parts so they can talk to each other.
@subtledriver appreciate the response. No I didn't to flush transmission. Which fuse would pop?...transmission control module fuse?
I got my ecu and ipdm from flagship one which is supposed to be programmed
its because bad radiator most common in that model
+Ali Aliali its a good video thanks for upload
Thats exactly what happen to my nissan frontier 4x4 it keeps blowing the fuse n 4x4 shows up n have trouble taking off but after it catches speed its ok why is that
Replace your radiator and drain your transmission fluid and change the filter asap! Or you will need a new transmission
It started messing up my dash has lights coming on n gears not working
That's not bc he didn't change coolant, the coolant and trans fluid should never mix, it's NISSANS FAULTY RADIATORS!
A common problem whit the nissan pathfinder radiator fail
I believe you mean well.
It's when engineers make parts that fail! That should not fail in this or that manner. No offense.
The cause is from a failed transmission oil cooler in the radiator. Recommend radiator replacement, all coolant hoses, flush cooling system completely, replace transmission.
His was bad, he let it go
I have the same.fucking problem with the nissan
I have to say you're wrong, though yes it might be due to the sensor in the transmition, what you're. Wrong about what caused it, how about telling the people the facts like how it is due to a faulty radiator, and that Nissan did a quiet recall while letting all of their dealerships keep selling them. Nissan wasn't the only company at fault considering multiple companies used similar radiators, but they took care of the problem!!!!
