Pontiac G6 Transmission
My G6 has a very noisy and Clunky transmission. I have had it to the dealer 3 times and I wrote and called GM. I believe there is nothing that can be done. Since it is the first application for this trans in a GM car, I think they just screwed it up. I am going to seek a buyout because I will not put up with the way this sounds. It really shifts poorly and cluncks into gears.

~~In need of help.
I would call the dealership service dept and just speak to someone about what you're experiencing and see if they can't narrow it down for you and possibly give you a round about estimate.
Good Luck To ya!

It might be the fact that it has only 4 gears.. rather than the "standard" 5.
I have been running it up and down the RPM's to get the engine set, perhaps training the engine, of course, not doing it abusively though...
Anyone with 4cyl, notice that the power seems to really pull further along the acceleration rather than more at the beginning. Which is kind of annoying, because I think most want bottom end torque.
Do you think the traction control is playing a big role in the way the engine treats its torque??...I bet it does. I don't have to use it all the time.
With less than 29,000 miles, the clutch is burned out and the heat from the clutch took out the fly wheel as well.
I had a 1992 Chevy Cavalier 5-speed and a 1993 Geo Tracker 5-speed, put more than 75k miles on the Tracker and more than 100k miles on the Cavalier, and didn't burn out either clutch. So I don't think it is "my driving habits."
I'm really hoping the dealer doing the repair work finds something that broke to cause this. Otherwise, it appears to me that the manual transmission was junk in the first place.
Anyone have similar experiences/ suggestions?
My 2007 G6 Coupe 6 Speed with slightly over 28,000 is in the shop today. They said the clutch is blown and the heat destroyed the sway actuator (spelling ? sorry). That it is a wearable part so it is not covered by the warrentee unless they fix it and then find that something else is wrong that caused it to happen. $1500.00! On a car that is 1 year old this month!
I too am a responsible adult not some hot rod kid, who has driven standard transmission vehichles for over 30 years and NEVER burned out a clutch! Arggg!
Anyone else having/had this problem?
I did get advice to call Pontiac Customer Satisfaction from a GM mechanic I know, that number is 866-790-5600 the representative I am working with is Charlene at extension 31364. My brother in law is former GM Service Manager he said to just call, insist that I know I am right and not give up. If they won't make it right I will turn my car back in.
A mechanic at the shop I went to told me that it very well could have been the check valve in the slave cylinder that if it stuck it would allow the clutch to partly engage which would explain the way it ran right before it blew. This would have caused everything to get hot; and if this happened it would be covered under warrentee.
By the way. My clutch feels totally different now than it ever did new. It is strong, pushes back quickly, shifts gears easy. Its a blast to drive. Was never this way before, this tells me that it was never right to begin with.
Hope this helps. Let me know how yours turned out.
After a couple weeks; although I thought my clutch "felt" great I began smelling the burning smell again. I called Customer Care again to report what was happening, they were even more rude and told me if I took it back it it was my choice but the file was closed and there was nothing they could do about it.
I continued to drive noticing the smell again every now and then. I took it in for service at my local dealership last week and ask them to check the clutch as well. Guess what the seal is leaking clutch fluid and needs to be replaced! I called Pontiac customer care AGAIN, to let them know that I would be taking the car in next week to have the clutch repaired, the first person I dealt with was very very rude, started bringing up all the stuff from before, I stated "look I am just doing what I was told to do, letting you know that there is a problem and I am taking it into a dealer that I trust to get it fixed" the operator hung up on me. I called back and got a different person, he was very helpful explained the process to me, apologized for the bad experiences I had had with the other operators, and re-opened my file for a second opinion by the local dealership. I still don't expect much from Pontiac as I am very disenchanted with them, but just wanted to let anyone who is having clutch problems with a manual G6 know that there IS A PROBLEM with the seal and or actuator leaking! IT IS NOT YOUR FAULT!!!!!!!!!!!
So any ways... I was totally devastated. I was crying, I don't want a car that I can't trust. I am so upside down on it right now that I can't trade it in anytime soon. I hate my car and really want to get something else but there's nothing I can do until I can get it paid down a bit more. I just don't feel the same way about it anymore. Does anyone have any ideas? lol
I actually think something is wrong with my transmission too. I have the 4cyl G6 sedan, and when it accelerates at about 40mph, with normal not fast acceleration it shifts quite hard into the next gear. There is 1 gear that seems to shifts rough. Also if I am in traffic going about 30-40mph, it shifts up and down a gear quite rough. Its almost like a lunging affect. I hate the engine!!! :lemon: It was never shifting real smooth when I bought it, especially that first gear, its so rough. I just thought it would get better with time. Breaking it in. But, it seems like it is getting a bit worse with time now. I am not hard on my engine, and when I accelerate, just let is ride up to speed, that is when it really just sorta lunges, roughly nudges right into gear. Who knows it might not be the 1st gear, but one of them is getting bad. Now, if I accelerate with a bit more punch, it will be a little less rough, but you can still feel it. I am not sure why they put the torque line so high up in the power curve? It makes sense to have it in the lower end.
When I take the car to get an oil change I am going to have them look at it. I am going to word it with a trust worthy person I know there. There is something wrong with my transmission. It lunges into gear. It feels like its slipping a bit. It embarrassing, because it might do that when I have people in the car. Now of course, it'll act perfect when they take it out. BUT, I am going to take out another similar G6, same specs. See what it feels like. My car has about 15k miles. It should not be acting like that.
I know the pain you are talking about. If you take that kind of pride in a car, it is disappointing to have no one believe you, and there is trouble with it. I lease my 08 G6, I want out!! Love the car itself, but the engine is truly a disappointment. I hate it! I miss my Honda engine!!!
Go to another dealer, contact GM, get a case started. Just give them as much information as you can. Drive another car like yours, have them ride in both.
If you think about it, you will have a new car, but a rebuilt transmission. You try to sell the car later, its documented, people will look at that. Instant value drop.
Is that your fault? NO! I would push to get out, as you no longer have a "new" car. I would file a report, either lemon with the tranny, (because the tranny is a lemon). Be firm. I certainly would NOT be forced to drive the car. In fact, I would tell them right off, If the tranny has to be re-built, I do not want the car, as the company is breaching their end of the deal, and I no longer have a satisfactory product, and will fact the issue in the vehicle report for the life of the car. That is not right, I am so picky when it comes to cars.
You no longer have a clean, new product, its been re-built! A bad tranny is a lemon. Be nice, and firm. Get yourself another car. This is not your fault. Its bad enough GM has value problems, let alone "re-built tranny" that screams out lemon!
Also, if I am in traffic, the transmission just goes up and down the one gear when going 20-40mph. You can feel it roughly slip back and forth into gear.
I am very well in tune with a car... and it just doesn't feel "normal". I do realize its not the Accord 4cyl engine I had, but it seems like that can't be the norm for an engine. Perhaps I am not crazy.
But, 10 times? What if I am bringing in my car 10 times because the transmission is acting up? You know how long of a period that truly is? That is not the way a new car should be? At what point are supposed to take action? Yes, make sure the car is treated as new. But, still the issue of having a re-built transmission is still at hand.
I still see it as the car is already a lemon. The transmission is a lemon!! There is no other word to call it. No other excuse. GM has voided their end of the bargain. They are pretty strict with us (consumer) holding up their end of the contract, but when it comes to the company, they can do what they want right?
Well, let them fix it, then drive it for a little while longer, keep track of your pay off versus trade in value. I figure, for me, I am 1 year into the lease now, but I think fall or the end of the year, I might have a better chance getting out.
Document everything, get the extended warranty!
I guess it does pay off to go for the car we all wanted to begin with. Cheaper does not always mean better. Just get the car you want from the start, then we will all be less likely to be unhappy during ownership and trade. Of course you were not planning for this to happen. So, the next car I lease, I am going all out (within reason) and get the car I truly want.
I want an 2009 Acura TSX with technology package!! It is going for a cheap lease right now!! I too am thinking of ways to get out!
My transmission in the G6 is still acting funny! I know something is not right.
a transmission should shift that rough or unpredictable.
If I would have gotten the car I actually wanted I would have paid less. My husband said Ford Mustangs are not a practical car if it is your only vehicle. So at the time we were going to sell my truck. We ended up keeping my truck so I can drive that in the winter. Hopefully keep low miles on my car will keep the value up on it a little.
When I went to get my car the mustang was $28,000 after negotiations and that's with taxes included and the G6 was over $30,000 with taxes included. If I would have gotten the 09 it would have been $35,000. They weren't willing to negotiate that at all.
I don't know. Pretty much what I got from the whole deal was the Ford dealership I went to were very easy to work with and the Pontiac dealership I went to were kinda cocky. Take it or leave it type.
Good luck with your transmission, I know how it feels, lol! Mine is still in the freakin shop. I call everyday just about to check on it. Been a week and 1 day today. It has also been 80+ this week and I'm stuck in my truck.
The money was spread on so thin. I surprised it hasn't hurt or taken a toll on the Cadillac brand. But, with that said... I think it is fair to say that the Cadillac is the full potential for the company, but its too bad that you have to pay that hefty unreasonable price tag for the car. When it really should be the kind of work or quality on their cars to begin with. You buy a base model GM car, you will certainly feel "base".
It is unfortunate that 13 plants are shutting down for the "claimed" 9 weeks. A few of which will not re-open I am sure. Many will be out of jobs. It will then create a bigger blow for GM.

Pontiac is Dead
I really feel your G6 pain. I have a 2006 G6. Rides nice, fits good, and thats about it. I have the 2.4 L. Tranny clunks...apparently it is building up too much pressure. Then the Engine light started coming on...apparently Camshaft Position Sensor, then Steering Clunk...Replaced Steering Shaft for the second time. Ran over a Raccoon...that took out my rad, and condensor...Ooops my fault not GM's.
Then that passanger side airbag sensor showed a service airbag warning. I don't have leather seats as in the GM recall, so I don't know what was up with that.
:mad:
I am not sure what is going on, it just doesn't feel right.. I think it is more than just having a 4spd transmission. I am not sure what I am going to tell my dealer for them to really take a look at it.... and make it look like I am not really dumb...lol.
I have to approach the dealer, approach the right person at the dealer to get something done. Perhaps my tranny was never right to begin with... but I am used to an 06 Accord 4cyl I had though too, but this just seems to be getting more weird.
Let me know.
The car goes in the shop at the beginning of the week, once I have to problem fixed I'll bring you up to speed on cost and bottom line problem.
:sick:
I would like to hear all opinions on what to do. This is my 1st brand new car, and I'm not having the time I thought I'd be having in it. Thanx
Also, if I get up to speed, about 50 or so, then let off the gas a bit. It sorta lunges too, lunges right off the gas. The transmission is not shifting right to me! I know the dealer will say nothing is wrong. But, I have decided I am going to tell them everything. That the engine absolutely sucks. The transmission is so rough, and having a new car that has 15,000 miles on it. I SHOULD NOT have to worry about feeling the transmission like if I had bought a car that has over 100,000 miles on it.
It does, it feels like I am driving an old used engine!! It has gotten worse, and I am not just feeling things.
As a consumer, we spend hours in our cars, we get to know our cars. Honestly it was sorta like this, but more smooth when I got it new, but its actually got a bit more odd and the shifting of the tranny is getting more noticeable. That alone is a sign, that perhaps something is not right.
When I am going into 55mph and my rpm's are still in the 3,000's,because the transmission hasn't shifted into the next gear, and when it does, it lunges or slips right into gear, you feel it roughly shift. There has got to be some sorta problem.
I love the car itself, I really do!! Its a fun, but the engine, its a piece of crap!!
But it could be the transmission.
Should I take the car in, and tell them to do a thorough inspection of the transmission. I think I will type out all the symptoms, so they can have it there.
Those that had an inspection... how long did they keep it...? I will need my car at some point to get 30min back home.
How do I word it good, so that I can be taken seriously, and be respected??
I really want to just call them, but sometimes it is the approach and talking to the right person that can do the right thing. Let me know how to approach this.
I called the dealership, explained everything to them. I bring the car in on Friday. Hopefully the find something. Because it does not feel right. But, from what others have said about both V6 and 4cyl engines, the transmission seems to act this way. But, I do believe mine shifts a bit rough, and that is more than just a re-program of the transmission. Its more mechanical. I want them to atleast tell me something can be done to help it. I am very concerned that they will tell me nothing is wrong and its normal. I drive the car all the time, I think I would know. I might even call a GM rep to keep them informed.
However, I will request to drive an identical car to see if it acts the same.
Just so you know, the Saturn Aura with I believe the same engine has had a few same issues. One had a transmission re-build. I've seen a couple of those.
I canceled my appointment, I left a voice mail for the "service manager" Hopefully this person understands what customer service is all about. I am so mad...
I just want to say screw it, if the transmission goes out, well let it!!
I will look for another dealer perhaps to look at the car. I will not be treated that way. Then dealers wonder why they have a bad rep?
not sure if anyone is reading this...lol. But, I did bring my car in, and we took my car and I showed them the issues. They did feel it too, but only like 1 time. I felt it more, only because I know my car better. I had a chance to take another similar car out, an 07 with 25,000miles. I seemed to have had more power and shifted better, smoothly. There was a difference. My car isn't as smooth and peppy as that other car I took out, with an identical engine, more mileage, and year older. We both rode in the other car and the rep felt that it was a bit more smooth, and I showed her the power differences.
I am bringing my car in tomorrow early. The 30yr experienced mechanic will look at it. They will have the car the whole day. I hope they can come up with a reasonable solution to the issue.
However, I am currently waiting to hear back from my dealer on trading for a VW. They have been so awesome so far, so if I am able to get out.. I will!! Its so far looking good. They have told me, I have $3,000 negative equity, but that is not bad at all!! You can work the sale price and numbers to make it appeal better. So, they are obviously wanting to help me. This is my dealer, so they know me, and have helped me... they sold me the car I am trading. They know I never wanted it to begin with. If they can get me out!, well awesome, I'll do it, if they can't, well, I will at least get my issue fixed on the G6. Hopefully!
Wish me luck!! My friend is wanting to buy as G6, I might tell her to look around first, then make a choice.
But, my cars engine, feels like an old grumpy engine! I am so nervous that they will not find anything. But, I wouldn't think they would keep it this long and then turn around and tell me nothing was really wrong with it. Unless they never got around to it yesterday.....hmmmm... Wow!
My salesmen told me he would drive it too. I hope that I don't look stupid!
Anyhow, get this, I was in there too, getting options to get out of my lease... and another person from my work came in, and have an identical car except it was an 09. They were there wanting out of the car too!! Same salesmen as me, we were both in front of him, asking him to help us to get out!! LOL it was hilarious! He was sorta overwhelmed with all of this... but I bet he wasn't surprised.
He used to be a fan and drive GM cars.... now he drive a C-Class mercedes! HAHA, and he told me his mom got a Jetta! So he is finally figuring things out!!
GM, Sorry bud, but your losing even your loyal customers.
After I transfer my lease, well, I will not be back to GM. Not feeling it!
I have friends who are mechanics and have driven it, their opinion ranges from a bad valve body or automatic clutch issue. But one guy says that the bad cam sensor could be related, it could be causing a high internal pump pressure or line pressure (falsely) in the tranny which makes it bang through the gears, or the pump itself could be bad too.
Did your dealer get to the bottom of it for you ? Since yours is throwing the same code ( P0010 Cam Sensor ) then I assume we have the exact same issue. Might be funny to compare VINS, I bet these vehicles are close on manufacture date.
Please advise what your results were... Thanks ! !
I live in Northern Ontario, so chances are we are probably very close on Manufacturing date.
Anyways...on the 2006 G6 the in dash information center basically tells you when to change your oil. I went by the percentages, car ran like crap, then the Cam Sensor code kept coming up, tranny problems, the whole nine yards.
I even switch to synthetic, and semi-synthetic oils. That made the problem even worse.
So what I did is went back to the tried and true 5W30 engine oil, and changed it every 5000KM or 3 months which ever came first ( regardless of what that Information Center said.
The Code has not shown up since, and the (what felt like Tranny) problem has not happened again.
Give it a try...it might work for you too. :shades:
The rental, an 09 G6 4cyl has much more pep to it than mine!!.... Honestly if the engine was not acting so weird, and random things going out.. I wouldn't be wanting out so quickly.
I refuse to drive such thing like that. I lease! I shouldn't worry about things like this. I pay too much, work to hard to be unhappy. Besides this is a sign to me, that I need to get out of it now!! Everyone I spoke with about it, was like... really? Yes! Get out! NOW!
Good luck to you guys too.
It turns out it wasn't the transmission. It was my catylic converter. It was replaced after a week of waiting. It seems to run much better, has more power, and the shifting seems to be functioning better! Now only time will tell. But, I think it will be okay! I am glad to know that they were able to find that and replace it.
I truly believe the car has a bad converter to begin with, since leasing it new. It never really felt this "normal" before. It feels like it is supposed to. Its not near a Honda engine, but definitely decent enough. I am glad to have my car back. I am seeking to still get out of it. transfer the lease.
For now, its all good. I am glad that is over... I will monitor the performance, but seems to be better.
Try pulling the battery off for 5 mins, the codes will reset and the adaptive shift logic will have to be relearned by the trans. Sometimes this clears up our issue for more then a few days. Reason I think its also mechanical is because the auto starter fails to work after awhile too until you pull the battery, trans may be building up too many codes and causing that to fail safe too, who knows. I hope you're on a lease and done with it soon as well.
I will just bring the thing in for every little thing. I mean everything! I'll rack up a warranty bill like no other!
She is calling me back on Friday to let me know what they can do for me. Either way, I am done. I am transferring the lease to someone else. As everything is repaired for now. :lemon:
So GM, if you want to honor my warranty and hold me to my contract... Well...
I will hold your company to your end of the contract with a nice warranty bill.
You know those labor fees are pretty hefty..
BY the way.. am not sure if I am being pulled a fast one... But are wiper blades for my car really $55?? You have got to be kidding? You would think I was driving a Benz!
A friend showed me this GM Service Bulletin:
GM
Transmission shift complaints and/or no engagement. Some 2002-04 GM cars (full list below) equipped with the 4T40E or 4T45E transaxle may come into your shop with a myriad of shifting and/or engagement problems. Among the complaints you're likely to hear are that the transmission slips, shifts erratically or not at all, or won't engage 2nd, 3rd, Overdrive or Reverse.
According to GM, the most likely cause for all these complaints is the shifting of a small sleeve within the driven sprocket support assembly. The shifted sleeve blocks the oil feed hole for the 2nd clutch. A new-design driven sprocket support with a tighter interference fit between the sleeve and housing (Part No. 24207143) is now available to address the concerns. Installing the new support will require dismantling the transaxle, although the clutches, seals, bushings, etc., can be reused if they're not damaged.
Vehicles that are susceptible to the above problems and can benefit from the updated support assembly are 2002-04 Chevy Cavaliers and Malibus, Olds Aleros, Pontiac Grand Ams and Sunfires and 2004 Chevy Classics.
Oh & yes - the wiper blades are costly, they didn't rip you off... but you can replace with the older style if you want (not as good though)
My 08 G6 is showing signs of the transmission slipping again. There seems to be this one gear that slips or roughly shifts into place. When in traffic going 30-50mph, the one gear is a bit rough slipping into gear. When accelerating up to speed it will hold on to the one gear, the you can feel noticeable it move into the next. Then say your past that rough shift.... then you need to speed up a bit, it will then jump down in gear... It just seems to jerky and rough to not be something wrong.
I have emailed Pontiac service, and they are calling me again today. I will discuss this with them today. I have only had the lease now for 13 months. I truly want out!!
This should not all be happening on a leased car. I feel like I went out and bought a used car with many more miles. Its sad too, because I was actually liking the car itself, but the engine feels old and grumpy! I feel on edge when I drive it, waiting for it to slip into gear.
What would you guys do?
So - just keep driving it, maybe manually shift it until it dies completely, sounds like a definite mechanical issue there, it will eventually become permanent. They will likely take the trans out for a look if it gets towed in because it can't move !
However, many other things can cause those symptoms - they should really be reading the codes off the transmission, not the ECM. The computer / ECM uses mass air flow / MAF and throttle position /TPS to determine engine load. The computer then uses those inputs to determine shift time and if need be increase line pressure to help stop any slip. You could have issues there but the SES light and a scan of the ECM should determine that. Mechanical issues should come to light with a diagnostic scan of the trans.
There is nothing wrong with the engines - they are great, well balanced and for the most part trouble free (both of them). Its the trans that are plaguing some of these cars I think !!!! Grrrr.
