2008 Pontiac Grand Prix Transmission Flutter?
HTML-код
- Опубликовано: 11 сен 2024
- Have a question on my 2008 Pontiac Grand Prix and I want to know if anyone else has had this issue. It seems like the transmission will do this slight "flutter" in between shifts once in a while, mostly at higher speeds or when wanting to kick it into a "passing" gear. Fluid and filter I believe are still factory, so I don't know if that could correct it, or is there another issue? Hopefully not. Saw a video of a Pontiac Grand Am that does the same thing. Any feedback, let me know. Thank you!

Also you can do a fluid change without any problems as long as you dont have it flushed. Flushing your transmission is a very bad idea as any debris that was sitting can clog your transmission causing an even worse problem. If you want to do a transmission flush then you have to have your transmission taken apart, cleaned and put back together before you have the flush done. Just add a transmission cleaner and get a cleaner for your fuel tank like Gum out, there is a cleaner by gum out that gets rid of debris in your gas tank, cleans your fuel injectors and does a few other things and I would add it to your tank every 3 fill ups. Something else that will help is not letting your gas level drop below a quarter of a tank to prevent any debris that is in the bottom from being injected into your engine along with the gas.
My car was doing EXACTLY the same thing for two years. Turns out at the last service it was overfilled by quite a bit. Did a flush and set fluid to proper level and now NO PROBLEMS! The 4T65e does NOT LIKE overfill by any amount
My throttle body was cleaned, fuel injectors cleaned, and still the problem exist. No issues are found when diagnostics. This car is crazy!
It's your battery. I know that sounds very crazy but if you don't have good connection to the battery or a bad battery it can make it seem like your transmission is slipping. Check out your battery first and see if it's time for a new one
Solved mine this weekend, it was doing the exact same thing as yours. My 2005 GP 129K miles was surging (flutter) on light acceleration typically 2-2.5K rpm range cruising speeds. I found another write up that said to clean the contacts on the battery cables and the smaller wire from the ground harness to the inside fender (Passenger side behind battery tray). I was skeptical but it worked. I disconnected everything, sanded the area down (below the small wire), cleaned the cables, reconnected and then covered with area with rubberized underbody paint so it would not corrode again. Took it for a drive, no issues, and I am now on day 2 with still no issues!
That's awesome! I'll look into this, thank you!
I had a pretty severe flutter on a 2010 Cobalt, especially once locked up in 4th. When it was happening I was trying to apply more load to the vehicle to try to keep the converter clutch better locked. I first cleaned the MAF, no go. Ended up clearing the pins with pliers on the IAT/MAF and this extreme flutter went away - I suspect the computer saw changing load from the MAF though perhaps IAT had some influence, not sure. Now, if I really really look closely the odd time a very very minor flutter could occur at extremely light loads but it is not felt and barely seen.
I have a 2006 pontiac gran prix and I have had the exact same problem with the RPM needle flickering and the car feeling hesitant to reach the next gear, then it starts to jerk back and fourth. I have read a lot blogs, suggesting fuel filter change, clean throttle body, and everything else. None of it permanently resolved the issue. I decided to make the big move, and had a gm dealer put a BRAND NEW transmission in. I want to leave anyone who is having the same issue with 100% assurance that the transmission is the problem. If you want your car fix, either do as I did or get your transmission rebuilt. My car runs smoother than it ever has, EVER! Best of luck to all.
You might have been able to replace the pressure solinoid in the transmission instead of the entire transmission saving yourself hundreds maybe thousands of dollars.
You can do a normal drop the pan, change the filter type fluid change if the trans pan is like that... just DONT flush it
Thank you for that info! That was something that was considered. I was planning on a tune up later this summer anyways. We'll see what happens when I do it. Thanks!
I have an 06 and it was doing the exact same thing. I had done the google and youtube research on the problem and finally decided a new transmission would be in my near future. I decided to keep driving the car till it completely went out and then I would replace it. Well I am coming in from work one night and park, turn the car off and the engine kinda shook as it stopped running. It had never done that before. I tried to start it and the battery was completely dead. I took the battery out and got up next morning and bought a replacement, put it in and go to work. The stuttering problem completely disappeared. It's been a couple of months and the problem has never reappeared. I'm not an expert so I am only guessing that removing the power had reset something relative to the transmission programming?? So if you are still having the problem, try disconnecting the battery for a while.
That's something that never crossed my mind! I had actually replaced the battery back in 2012 because it would completely die. Before I replaced the battery, I don't think I've ever had an issue with transmission. However, I may disconnect the battery in the near future and see what happens. Thanks for the input!
Wayne Lowry i just went through the exact same thing
I think it's the Spark plugs for sure! I had the same problem fixed. They changed the spark plugs and fuel injectors!
My mom lives in Central Illinois and has the same problem. I just learned about it this morning and found your RUclips video She is 83, still drives and said her eng light has come on. I live a thousand miles away.. I shared what you said on on your video. waiting to see if it helped. Thank you.
Denise Alvarez
if you disconnect the battery and let the car sit overnight or for a couple days it should stop the issue
I have an 04 pontiac gt2 with 107k miles and recently its been shifting kinda hard on 1st to 3rd sometimes its hard shift or sometimes its subtle it sucks cause i dont really have the money right now so i pray its nothing serious untill i can get the cash to do something about it
Thanks so much for your video! I was having the exact same issue with my 06 Grand Prix after disconnecting the battery for a while and connecting it back I haven't had any more problems.
Brandy Brogden Awesome! Glad to hear it!
+MichaelAdamsRocks have you had any issues with the headlights and the dash board lights flickering while driving on your grand prix?
Brandy that is 4 thangs battry geting old , loses cables on the battry , your ground cable lose the one that connects to the frame of the car or alternator going bad and time get new one any thang deal with that light flickering are those 4 thangs
Torque converter. Need transmission fluid change but "don't" flush yet. Chance the fluid and filter, run about 1000 miles of that fluid. Then change fluid and filter and flush if so desired. Most shops will not flush if you have had slipping. Just FYI. 2006 Grand Prix owner. Good luck bud.
Something similar here and it might actually be the BCM. Also, wouldn't lock with the buttons and the temp gauge works on and off. Unless the transmission is actually slipping or shuddering it likely might be electronic
Lose battery cables messed with my transmission I tightin them up shifts like a new transmission with 192000 miles
That dont even make sence
@@doodoobutterandjelly69year70 If a trans is getting low voltage or low current. All the solenoids are going to get low voltage or intermittent voltage. This could cause a solenoid to come in and drop out. Making people think its bad. But its actually not getting a good signal due to corrosion in a power supply
My 97 Grand Am was
Doing same thing..
Result was..
Loose Ground on
Under good Fuse
Box..works Fine
now.
ok so i had this problem i think in my gtp i figured out that it was ME....yess ME .. i was pressing the gas just at the right point my trans was getting confused in a way.....trans work off pressure in at least autos to change gears when you slowly push the gas it starts to build pressure... the harder the gas gets pressed the faster the pressure builds when it gets to the point of shifting up or down it shifts your kinda like getting the trans right to the point of wanting to down shift but not quite enough to shift down a gear .....see what im saying ...hope it helps you out ....mike hardin
That doesnt cause slipping and jerking, its an automatic not a standard.
Hey don't know if you fixed your car yet but I have a 07 and had the same problem. I had a bad sensor/solenoid on the transmission. $300 it fix it.
Who had fixed it..
What sensor
Hey It was the transmission. something to do with the solenoid and the torque converter. My whole transmission was replaced and it fixed the problem. Also thanks for the video of the HOW to change shift lever light I had to replace my bulb too but couldn't figure out why that back part wouldn't lift up. Got it after seeing your video.
I am. It's still a mystery if it's the transmission or maybe a clogging fuel filter or something. I also started to wonder if the throttle body could be dirty.
Had similar issues. Changed all plugs, wires, coils, tightened and cleaned all grounds, checked fuses, cleaned throttle body and maf. Didn't change anything. Checked tranny fluid and smells burnt, about to do a change and switch out my egr valve. Do you get a surge at high rpms or feeling of backfire? Any hang shifting?
Having the same issue at lower speeds with Acura MDX shared 2014. The problem has significantly worsened over the past 4 years.
I had this same problem for years and was driving me crazy took it to the shop and they said it was an O2 sensor then they replaced the cat after that it continued to do the same thing I finally found out what the problem was I had a small antifreeze leak and after putting in some antifreeze sealer the problem is gone and my car runs wonderfully!!
Huh!..
so what exactly fixed the problem for you because I have the same car and mine does it bad when shifting into 3rd or 4th
look like the torque converter lock up is in and out. Do it feel like going over mining speed bumps like on the hwy on the side when pulling over?
I have a 2000 that does the same thing. I was told it was the mass air flow sensor, so I replaced that and most of the front end parts and it still does it.
My 2005 Grand Prix Gt's transmission slips now and then. When I accelerate from a stop position, it hesitates and then grabs, and jerks you back. From a normal running speed it's shifts fine and yes I've changed the fluid and filter. Anyone else with same issue?
it happens still with mine and its not in drive but in 3rd would that still be a transmission problem do you think?
Sounds like it......These GM transmissions for the GP & Bonneville are suppose to be pretty good..Perhaps we got stuck w the lemons..lol
Renato Laureano Hey It was the transmission. something to do with the solenoid and the torque converter. My whole transmission was replaced and it fixed the problem.
I have a 2008 Impala with the same problem I know this was a long time ago did you ever figure out what it was
I would suggest checking/flushing your transmission fluid. I've seen plenty cars with old transmission fluid get burned fluid or debris build up and it can cause difficulty for gears to catch.
I have had several gts and now a gxp all these cars transmission s run too hot in my opinion . So I now replace the fluid with synthetic transmission fluid and add a big rv cooler in line with stock unit and a shift kit . And will be doing a transmission service once a year by suctioning fluid out the transmission dip stick tube very easy and 7-8 quarts can be removed . I did the fluid service annually on my 2004 which now has 408,000 on the original trans and motor and they both work like new every 3 year I change the filter
@@nickking1510 that’s crazy you suck the transmission fluid up through the dipstick it sounds like that would mess up the filter that is in the trans pan really surprised u have had no problems
@@chadjay828 no it works great gets about 7 liter out of my Grand Prix gxp 5.3 I do it once a year . Also do it on my 2004 Grand Prix gt 3.8 it’s got 408700 original transmission shifts like new I change filter every 3-4 years . Most people never change their transmission fluid or differential fluid power steering or brake fluids and they blame the manufacturers when in reality it’s their negligence . I use a small had operated transfer pump after warming up the transmission . My transfer pump has plastic 1/4 -3/8 waterline to the suction side and about and it takes less than 15 min to change it .I have never had an issue doing it and my gm cars have filters in metal cases . Have used the suction removal since 19 71 on gm turbo hydramatic 400 and
350 f150 and gm 4L65 hd and many others . Also most in board boats engines are suctioned out as there is no room under the engines to change motor oil marine service centres have vac oil extractors for that use
Someone else mentioned this, but my Check Engine light isn't on. I had a 92 Bonneville that had an air flow sensor problem it made the Check Engine light come on. The thrusts that it did though weren't like this.
Hey. My 2006 Pontiac Grand Prix has been doing something very similar. do you have any idea on what has been causing the problem yet? I been doing some research and came up with the transmission solenoid issues. Causing erratic shifting. I Hear replacing the pressure solenoid solved the problem....
@@willister54 could also be something as simple as a motor mount
Hello, I am replying to the fact that my car had the same problem with the shuttering, I drive a Grand Prix Pontiac GT sport . I change the transmission fluid as well as the filter and also put some shutter fix in it along with some Lucas additive that helped The problem a little bit then I Clean the throttlebody and the mass airflow. After doing that I noticed that my ignition wire/plug was loose One of them clicked back into place and the other is busted after just plugging one back in after it snapped in it completely change the way it was driving now it only occasionally shutters and I assume that it will go back to normal after I replaced the plugs with new ones but that seems to be the problem. It tremendously helped my cars performance!
I ended up resetting the computer by leaving the battery disconnected for about an hour. Hasn't shuttered or shifted poorly since.
The fuel filters on this generation Grand Prix are built into the sending unit, so I'd have to replace the whole thing. That's anywhere from $300 - $500.
i've oned a 2004 GT, naturally aspirated, & a 2006 GT Supercharged & had the same probs The 2004, I had to replace coils, plugs, air filter, catylitic converter & fuel filter...all the same time, & PERFECT! Then traded for an 06 supercharged...then the same..Plugs,wires,coils,fuel filter but not the catylic converter, & the car ran perfectly fine! I had the same problems as you, the mechanic done these repairs and it fixed those problems.But I stil changed fluid & filter in transmission NO FLUSH
I have this problem but my car Shuts Off completely in mid drive. I have to shift into neutral while coasting, turn the car off then turn the ignition in mid drive to regain response... or I'd have to coast of to the side of the road and park and restart car. A lot of the time my car has trouble restarting again, it takes 2-5 mins worth of trying to get it to start. 06 Pontiac Grand prix. any feedback would be greatly appreciated.
built in fuel filter on pump maybe. But sometimes there's one little member that gets overlooked and Even GM parts and service tells you there's no listing for it but it has one. and that is the PCV valve. it's in a very well hidden place on the manifold. It's beneath the mass Airflow sensor. Remove the wire connector from the sensor. Now it's going to be very tight. turn the sensor assembly counter clockwise. Careful though, there is a spring underneath and it's a bit spring loaded. Voila underneath you will see the PCV. valve. If these aren't changed at a 30000 Km interval ( every 2nd oil change if your running synthetic) they will plug giving a false reading and cause all sorts of readings on your H.U.D. they will plug and get super stuck in the manifold bore it sits in and gummed up. robbing power and preventing the transmission from upshifting properly or fluttering. That sensor might even be called a crankcase pressure sensor but it looks like a map sensor.
By flooded, do you mean the fluid is overfilled? Or do you mean something else?
you still have your grand prix? I have an 05 . sounds like a mass flow sensor. That is common on GM vehicles. Change that . It should be fine
same thing im saying because a week ago my car would start up idling up and down and now I have a flutter. I had the same problem on my 02 Buick LeSabre series 2 and it was the mass airflow sensor but the only difference it didn't flutter it would cut off at times when cranking the engine and sometimes when I came to a red light.
Sounds like a pressure problem in the transmission which means 1 of 3 things (Mine has the same issues) you have to replace the pressure solinoid in the transmission or the transmission itself or your computer has a sensor issue which is causing the car to have issues building the right amount of pressure in the transmission. Let me know if your grand prix is still slipping and jerking and also tell me if you ever have a pop up on your display that says "reduced engine power" with an engine icon.
Mines jerk at low rpm
@@liftedlife9046 That sounds like your transmission is going out.
@@0blacklightning046 yea I had got code p1811 I had low transmission fluid n da gasket had leak
@@liftedlife9046 That makes sense.I unfortunately had to get rid of the grand prix. Some stupid lady hit it in the autozone parking lot where I worked and she totaled it
....
@@0blacklightning046 I just got all dat redone it’s still doing it I just put sum sea foam in it doe n I got knock sensor code too my transmission started doing it when I changed it a couple months ago
My 06 does this I either have to push the gas harder or let off it also uses a lot more gas when doing the flutter. Mine usually starts happening around 50 55
I currently have a similar problem with my 1998. Mine gives a little more of a stutter with it that you really feel. Yesterday I did spark plugs and wires they haven't been changed in a while. It brought back some performance but didn't fix it. I'm going to try coils next. Then if doesn't fix it I'm going to do a transmission fluid replacement. I'm more comfortable doing things under the hood rather then under the car personally. Good luck with yours.
My mechanic thinks that the clutches in the transmission are coming apart. The fluid in the transmission is no longer red. He told me that I'm better off letting it run it's course and dealing with it when it finally bums out. I'm still doing a tuneup eventually and keeping my fingers crossed.
well my transmission completely blew last week..... so its a good bet. haha by trans fluid levels were fine and so was the color. But the car is toast.
My 06 Grand Prix was doin the same I changed spark plugs n spark plug wires n the control module and it stopped doing it
How much did that all cost at once ?
I had the transmission fluid flushed on mine about 2 years ago, right after that it started doing the same thing, i added transmissions additives and the seem to work for a while, then one day the map sensor went out and after i replace it the transmission started shifting smother than ever did before but after a few thousand miles it's doing the same thing again and i added lucas transmission slip but didn't do anything this time so i'm thinking about changing the fluid and filter again, i might even replace the transmission solenoid if nothing works i'll just drive it till it breaks, the only difference is the my pontiac gp has almost 209k miles
Exact same thing on my 2007 GXP-80000 miles. In the shop having a new transmission installed. This was eight moths after having it serviced. When they dropped the pan, debris and metal was found. So sad!
If you are ever under the hood (or doing something with the transmission in particular) examine your torque converter and shift solenoid. Although the shift solenoid is a more common problem for our cars. Do you have a GT? Because It seems that the transmission on the GT's (4t60e (non hd)) have this problem more. I don't know a whole lot on the transmissions on the 04+ models (I own an 02') but I would imagine disconnecting the battery, for how ever long feels safe to you, would do the trick. If that doesn't work just replace the solenoid (I assume you already know that though haha.)
have a 2004 and have tried to flush and change the fluid every 50K no real problems except on a long trip recently slight very slight lurching of the car seems from the Tran. and your check engine light probably is only a bad thermostat - I have friends in the business so that helps - my favorite car that I have ever owned - smooth ride
Michael, I am having pretty much the same issue as you and as well as the rest of these good people here. My 05 GP GT has been a nightmare since I bought it. I've literally had to replace so much on this car, it's crazy and often times I swear the car is cursed. You said maybe disconnecting the battery solved the issue which I'm going to try but as of now, if that doesn't seem to work, what else can you suggest to me as fix? I really do like this car and would hate to have a bad taste in my mouth over it. Any help is appreciated!
The only thing I could gather out of the whole "disconnecting the battery" thing is that it resets all of the computer related items in the car, including the transmission solenoids. Once the battery is hooked back up and the car is driven after, the computer has to reprogram the shift patterns to the solenoids, which is why I haven't had major issues afterwards. Replacing the solenoids or the whole transmission are probably the only other two options if the battery disconnect doesn't do it. That's all I can think of.
+MichaelAdamsRocks thank you! I did the battery earlier and it seems to have helped out a lot!
Glad to hear it!
You might try the "battery disconnect/reset" Then recalibrating you're TPS/MAF and foot peddle
Dang, I'm sorry to hear that! The only issues I've ever encountered with mine is once in a while it won't start right away. It will run shaky for a few seconds and die. The second time I try starting it, I give it a little gas after it starts and it runs fine. I heard that's common with the electric throttle body that comes on these Grand Prixs. I was going to have mine cleaned out to see if that makes a difference. Good luck to you though!
Be sure to check your ckps.
Could also be a misfire
My 2006 GP has a flutter/shimee,at around 2000/ 2500 rpm it has 179000 miles...Fluid has been changed once around 100,000 miles...Already went through a transmission repair on 2005 Honda Accord EX V6,it leaked first,it cost $2900....3 year warranty,then failed out right torque converter and a few other things at 2.5 years...Covered and rebuilt...
torque converter
not locking up
i have a 2008 grand prix. it starts fine, however when trying to drive/reverse it only goes so far before i have to turn it off and start it again for it to do the same thing.
My car does the same thing, only going over 60mph. Trying to figure out a solution
I had SOOO MANY problems with my GP first the damn turn signals then the front fucking lights went out then when I tried to start to itit would have a problem starting THEN I had this problem your having and then it turned out to be my transmission and then THAT failed .
watched this for a minute and a half and know he needs some serious transmission love
+Greg O Get yours rebuilt like I did at 90k miles under warranty. do your research, know your shit
Well if I were you I would defiantly clean the MAF & TB. I would check for loose wires and change air filter stuff like that. How does the transmission fluid look and smell when you pull the dipstick out and is it at the correct amount? To much or to little will mess up your trans quick. Also I would check the spark plugs and spark wires and replace if you haven't done already. You also could try using seafoam which cleans everything out.
Just started having this problem with my daily driver which is my 2006 Pontiac grand Prix. I'll need to take it to mechanic to see what's wrong. Not really trying to put to much money into it. Hope it's nothing major
I have a 2007 Pontiac grand prix with 86 thousand mi on it and the transmission went out on it. I owned the car since new and babied it. It has the 5.3 v8 in it. I just got an estimate for a rebuild on it from a local garage of $3500. That's with a 2 yr. Warranty covering labor. Sounds high to me. Any thoughts or suggestions? Thx
It could be that your ignition control module is going out... My car was doing the same thing at 70mph the R.P.M would go up and down slightly but noticeable .. Till a Year later it went out... And if you buy this part, buy original gm ignition control module.. Any after market part will fail.. Believe me it happened twice with after market ICM 's.. Grand prix are high maintenance cars when it comes to engine components... I have a 2006. It's a good car, well built engine, fast and reliable when it's needed .. But it's a top dollar bitch..
Thanks, I have an 06 too and I've been experiencing this problem for about 3 weeks now
Check your radiator, because, sometimes have a hole inside start mix up coolant with transmission fluid and contaminated engine/transmission …..
I have this exact same problem literally identical to the way you described it on my 2005 Grand Prix
It's probably a bad EGR valve like mine. I bypassed mine and am about to tune it to delete the CEL code from appearing.
I have the same problem thank you ! What can I do too fix it ?
I have a 1995 grand am with transmission shudder. I added a liter of anti squawk/shudder from Lordco it helped for a while now back to problem. 3100 great shape 200ks. Was told TCC (torque converter clutch) solenoid inside trans, hoping not cause time issues and definitely no shop gonna get their grubs on any of my vehicles, looking for successful stories thanks anyone
I know this is a old ass video but I think the flutter is related to the dod
My 04 Pontiac gran prix supercharged currently 243 ,500 original miles. It just starting to have similar issues. My mechanic told me .if I do a full flush. There is a good chance it wont drive at all. I'm not sure if I want to take that chance. However if you have a second vehicle. I would take the chance.
i have a 2007 pontiac g 6 with a 3.6 litter engine i do not know the tranny size or model but when i am driveing it it runs great for a while then it will stop moveing after the trany gets hot the check engine light goes on . but the engine is still running great what could be the poroblem with this car
Did you find out the problem?
I have a 2007 and its winning and when I go to take off it acts like it doesn't want to go but does than once I go its fine
Do you figure out what the problem was i have the same problem put i only have 67,435 miles on my grand prix
Do you mean it hesitates?
I have a problem with my 07 where if I try to pass the car will not go some times when I let go of the gas it speeds up then I can pass it's like it's not catching gears or maybe not burning gas fast enough
Hope to all owners, this fluttering can last years and not really do anything but annoy the shit out of you. I have a 2002 grand am gt has been doing it 3+ yrs. Started when a tire company (lets call it LeS) put tires on the rear that rubbed against the actual springs for 10k miles before I NOTICED and took it back in. LeS wouldn't pay shit but replace the tires (the springs had worn a gash into the inside of the tires!) Yes, I should have taken them to court....
Now, 3yrs later, its only (at 157k miles) just now getting to hard shifting, about once a month, then it will start up fine again and only symptom is fluttering between 60-70mph into overdrive on the freeway. I've replaced battery, reset computers, the tranny was flushed when i bought it, but the damned thing is going to need tranny wrk.
I think the drag caused by the tires actually touching springs and dragging on them for 10k miles ruined something in the transmission before the tires were replaced with the right size. Amazing how stupid tire retailers can be and be warned@@
Trans fluid to SOOO important. At minimum, at least drain and refill ever 2 years or 24,000 miles with Dexron VI (Amazon sells for less). Also, many that appear to have trans problems are really have ignition issues. Change all plug wires and spark plugs, I wouldn't be surprised if this cures your problem. Clean the coil packs as well. Looks for codes as well that point to multiple misfire if it gets really bad. No mechanic in a bottle, not a way to fix your car and seldom does any good.
I have an '08 G6 and its when I'm on the highway mostly going around 70, especially in cruse, and its like its sputtering and cant switch.
Dude, any update? You posted a year ago, but my 08 G6 at freeway speeds and light cruising, the transmission flutters as well! Everything works just fine but it definately flutters
Find my comment and see if that will help you if you still havnt found a solution
should be throttle positioning sensor I've replaced on a 2001 Mitsubishi Eclipse, and a ford ranger... but It could be something else, check your ohms on the (throttle positioning sensor) and check to see what it should be in your haynes repair manual
Hi Michael, guess what? My Grand Prix wont start now. just never seems to end with this car. Have you had any issues in regards to starting. Rack and pinion issues resolves last month. more and more money this car has cost me close to $35,000 in purchase and repairs. :(
My 08 gxp just started doing the same thing rpm jump up down think it's the trans only 144.000km not happy
If the additive you're referring to is called Lucas, please don't use it!!! I used it and it completely ruined my transmission to the point of needing a new trans.
jphritz011 lol, not trying to be a dick but did you use the lucas trans additive or oil additive. Ive never had a problem.
it looks like it is having misfire at a higher rate of speed. i had the same problem in my 05. i changed the coils, wires and sparks. stopped sense.
Did you figure it out?
everyone listen to me carefully i had the same problem with my 2008 transmission its not the transmission it is your mass air flow sensor needs to be cleaned also clean the throttle body too but the mass air flow sensor is dirty any little spec of dirt get onit it will not read properly get mass air flow sensor cleaner let dry take your battery pos off and put it back on to reset it it should be fine
I wondered if that sensor could be an issue. I had a 92 Bonneville that had a mass airflow sensor problem, but it would "power thrust" rapidly and randomly stall too. Thank you though, I'll try to get take care of this.
@@MichaelAdamsRocks Did you ever try replacing the mass air flow and did it solve your problem? I have this issue currently and would appreciate your input. Thanks in advance.
Ronald Finding thank you so much for the insight, you were totally correct! I had this issue on my GP 07' and was worried my transmission was going. I tried the MAF or MAP replacement and it completely solved the problem. AWESOME! Saved thousands!
Do you have aftermarket rims and tires on it?
My 2006 Grand Prix GT, doing that too. I believe its coming out of OVERDRIVE GEAR. If you give it gas while your on the highway - even a little... its gonna pop out of overdrive. I don't believe its slipping ???? I only have 58,000 miles...
I've changed my fuild twice all ready. Once at 60,000km, and again at 110,000kms ( this time with a litre of Lucas transmission additive ) because I as experiencing the same problem. It dud not cure it, although it does not happen as much.. Thru more investigation, I have heard that the torque converter is the culprit! This is a costly fix!! You know it must be done, but man, $1200.00!!! Gotta wonder if the car is worth it😕
Wondering why that little orange sign is up . On the far left
Bad tire pressure sensor
My car is not ready my mph it stays on 0 and don’t wanna come out of gear sometimes then after a while it doesn’t do it
The Grand Prix I got does this when it’s at 5000rpm and it flutters like a pile of shit then the check engine light is flashing I turn it off and on then it’s like it never happened
I had a 1992 Bonneville that I had to replace the mass air flow sensor on. It would do sudden thrusts, but not like this. Plus, those usually make the check engine light come on like in my Bonneville.
Did you ever figure this out. I’ve got an 04 gt and it does the same thing.
Tranmison could be the problem but frist clean the throttle body that sould be step one it the cheepes. Next move on spark plug, wire, air filter ,oil, coil packs and o2 sensors . if its still doing it. Look in to the fule pump and thebfule filter it might be geting to the pont for new one. 2nd to last deal with your passer frunt tire it going be the drive shaft sense it longer than the driver side frunt wheel drive shaft. over time it get perty won out especially when any year and make of this tipe of car hit 200,000 milles or close to it that this shimy and jerk is the frist sign when cruz contol set try go up hills its start shiming and it may seem it the tranmison but it will me more noticeable on curvy roads with sharp turns that shimy get more pronounce and that will still cost less then have a transmission rebuilt and still have the same problem if you didnt go head with the cheeper rout frist. last one is finely the one thinks it is then you were right all long and is it is the tansmission and if you have the money... rebuild!! it or just get new one. Witch ever but you might want save little extra and get you engine overhauled as well that way your car will live on futher and it will keep you from being discussed with the car when any thang mager go wrong. But im going thew the same problem iv already got new air filter oil change and clean throttle body With my car so it still has the shimmy now im on geting new spark plugs wires, coil packs and o2 sensors. so we will see but people replace that drive shaft on passger side the problem gose away and at less you gave you car a full trun up be for the problem got solve and over time you could be slowly saving. To buy the drive shaft why replacing the small stuff
my 2008 pontiac g6 did they same thing couldnt check fluild levels but i added a couple of quarts of fluid and it stop.read some where it should be topped off with fluid
Has anyone got this fixed? My 2010 Pontiac G6 Gt is doing the same thing. I don’t believe it’s my transmission. I’ve replaced my vvt solenoid “the magnet” didn’t fix this either. I’ve also replaced the vss as well. I notice on RUclips it’s common amongst Audi’s, Dodges, or Mercedes. I’m wondering if it’s my belt tensioner? I have been noticing it moves a bit at idle.
Both car were at about 100,000km`s when this needed to be done to fix those problems
Mine does that my mechanic thinks its a throttle body another person that works on cars thinks o2 sensor
I have a 08 Grand Prix and my did that for about a couple of months I didn't know what was causing it and now it sets in my drive way not starting someone told me now it something with the pcm. But other things like digital on radio went out and one sensor for the tire went out so just FYI don't know if it means anything to anyone.
If anyone has updated this ... i had a similar issue with my GTP, it turned out to be a few items causing it, but bottom line is it is NOT a transmission issue but more so related to the engine.
I was lost for ideas and thought it would need a trans service.
In my case it was a combination of old spark plugs, a dirty throttle body, and cheap gas. Mainly cheap gas caused some of the issues (89 octane). Got new plugs, replaced distributors with junk yard set, ran seafoam, through the throttle body, intake, and a can in the fuel tank. After that we hit the road for a good 1500 mile round trip and the problem never showed up since, it was so bad in my case it would jerk the car in that odd lock up position.
Main solution for my setup seemed to be the fuel.
I would try the spark plugs one going bad can cause a ton of misreading by you start out with little stuff first
No. All stock.
it may be something to do with idling wrong too dood
That's what I thought it could have been originally.
I seen ur temp gauge almost get up to the third line. Dose it ever go past that Mark when u are at a light or when u at an idle. My girlfriend has an 06 and gets hot at idle. Just wondering cuz I have Done everything except replacing radiator.
It never reaches the third line often, usually goes in-between the middle and third line if I'm sitting with it idle for a while. Other than that, it stays at the middle line often.
Ah ok. Thanks man.
Dustin try
tightening the manifold, it may be loose. This is what happened to mine too.
Ok I'll give that a try thanx.
