Chevrolet Impala Transmission Problems



  • That is exactly what my local dealer in FL told me, plus no codes on the onstar either....
  • Also told Jim McKay to keep it for 4 or 5 days to test drive it. I also told the service guy that I will come and drive it and have one of the techs ride with me.
  • well #392of 409 If and only If none of us purchased another GM car we can make them feel it, like we have to feel it. just keep telling folks and at some point gm will have to face the loyal customers they screwed! I'm so pro 'non" gm. funny how the dealers know this and will try to get you to buy this crappy car (I know) another of my family members went to gm up in nj rt 22. needless to say when I was done they went across the road and picked up a honda. sorry gm I can't sit back and watch you do this to people.
  • Take it from someone who knows....I have just had my 2007 SS Impala Transmission rebuilt and not by GM since they said the company that last did the routine transmission servicing caused they problem. (the transmission company management were as shocked to find this out as I was but held on to their integrity with me by fixing it at just the cost of the parts to completely break down the transmission.
    I am afraid from the description you provide that you have about 3,000 miles left before the transmission begins to lurch from standing still. Start recording this problem now with GM. If it is not covered under the ORIGINAL 3 year warranty, more than likely, they will not cover it or find a reason not to. They will offer you an option of purchasing a new transmission at about 3,000. Do not accept this offer. The transmission must be broken down. There is a flaw in its design. That is the reason the new transmission is cheaper than rebuilding it. Sorry for your problems. I know how you feel, but I don't think the flush will work.

  • Jim McKay replaced the PC Selenoid on my 2008 SS Impala today, 11/6/2012
  • To all that are having problems at between 60 and 70K miles on their impala transmissions of these years, please note this.

    When you take it to the Chevy dealer of your choice, which is what the gm customer service department will tell you to do, they will offer you a "deal" of putting in a new transmission at around $3,000.00 with a "warranty". Do not accept this option and get out of there if you have to have your car towed to a reliable transmission specialist.

    Ask any transmission company who just handles transmissions and they will tell you how many of the Impala transmissions (also in other gm vehicles) they have fixed. What gm does not want you to know is there is a design flaw in the transmission itself so the option of putting in the same flawed machinery is not as good as it sounds. In order to fix it, it has to be broken down. Now my Impala runs better than it did when it was brand new. It has the feel of so much more responsive power like a car from the late 60's. However, I own this car because it was my dad's last vehicle. I WILL NEVER OWN A GM PRODUCT AGAIN.

    GM blamed my transmission specialist who just did routine maintenance on the car for the beginning problems with the transmission. (NOTE: I HAD ALREADY STARTED A DIALOG WITH GM CUSTOMER SERVICE PRIOR TO THE TRANSMISSION COMPLETELY BREAKING DOWN) Expect this response if your car has been near any other service source.

    Forewarned is forearmed! Buy Ford or a foreign brand!
  • Hey had shutter from a start, then it went away but started sputtering at 80km an hour,took it in to a chevy dealer,6 hours later said it was shift solenoid,3 days later tranny was slipping bad, brought it in for service,got there and when they went to drive in bay I lost all forward gears... now the tranny is out and they say its the forward clutch and drum. Oh I have A 07 SS,
  • Im hoping this takes care of the problems the PC Shift Selnoid. We will see.

  • gm social media really tries to act like they are concerned with your chevy problems. However, be ready for the lies coming out of the mouths of the mechanics who will blame you for the problem. Gm will take their word for it over yours.
  • My Son's car just came out of the shop for the 3rd time in the last year and it still is not right. The tech at the dealership told me that all these transmissions are underpowered for the SS. Now I have to fight the dealer ship for outrages rental car costs for a covered repair. We have always bought American cars, I drive a Chrysler, my 3rd , I am so disappointed in the them not standing behind the product. My son will be filing a complaint with the CA automotive repair bureau if we don't get satisfaction from the dealer.

  • Just had my transmission worked on after having the symptoms like your car. I have a 2008 Chevy Impala LTZ and they replaced the pressure control valve and the valve body and that seems to have done the trick. It was under warranty.
  • How is your car running now? Did replacing the pressure control valve and the valve body resolve it? I have a 2007 Chevy impala and it has random issue where it hesitates and then jerks forward from a stop and then again around 40 MPH. I took it to my mechanic and also transmission specialist. The first place took for a drive and encountered the problem, but it didn't send any codes to their computer. They said until it sends a code they would just be ripping things out trying to guess at the problem. The transmission place took it for a drive and didn't experience any symptoms and No error codes either. Argh this is so frustrating..don't know what to do. Curious to know if that repair resolved it.
  • Same as thousands of others. However...from reading around...and speaking to my guy, who has several contracts with city employee cars (Impalas), in cluding police dept....I now know why cities shifted from Impalas to the Dodge chargers. Replacing that valve is only a temporary fix. The computer is also reading "wear" in the transmission. Much like me who is almost 50....I could still play softball like I did in my 20's but my body would object and constantly give me signals not to. That's how it was explained to me in layman's terms. I am currently having my tranny rebuilt...will eat the cost...sell it at book value...and get away from American cars period.
    My husband and I just got burned by a Saturn ion last year...the dealership replaced the motor and security system...but the motor lost 2.5 qts of oil in 16 miles the first day home....and lost a qtr after that faith in American cars is toast.
    We have a 1988 toyota camry that cranks,rolls, with over 250,000 miles on it....and never had any major issue. I may be a dreamer...but to me...I've got my moneys worth from that car...which is how it should be. Good luck!
  • Same thing happened to me - It turns out it is a combination of two things: one - the second gear clutch assembly is mildly exposed to weather - thus becoming less lubricated and 'sticky' if you will. If you are still in warranty it will be covered with your dealership - there is a service bulletin for this problem as well. Secondly, GM uses a 'learning' transmission - so, as this condition worsens, the ECM thinks this is how you wish to drive. So the problem will continue to worsen. Once you replace the second gear clutch assembly, make sure to reset your ECM, and your transmission will work fine!
  • I too am done with (not american cars as no car is really american only), the big three; GM, Ford and Chrysler. I do not know what they are thinking! step up to the plate and admit when a problem is present and fix it!

    I can proudly or even sadly say that no less than 10 car buyers have now purchased other brands after hearing my issues and having sent them to the numerous chat ([non-permissible content removed]) groups related to the big three. I will keep preaching this as long as I live!

    Hope you are happy screwing your loyal or once loyal customers GM!
  • I've recently purchased a 2003 Impala. I've read several complaints about this model car. According to the owner's manual, certain cylinders will shut down to prevent damage to the motor. In this case, the car would feel as though the transmission is slipping. At best, the thermostat may be a cause for the cylinders to shut down. But, according to the check engine codes, it had something to do with tempature gage. I replaced it, but the check engine light is still on. I have to wait until the next diagnosis. Then better I could report. I am also very upset to learn all the confusion caused by this car. Is this car worth the problems? Comments such as "you bought a lemon", and, "this car is a piece of junk", are not the comments I'd rather hear with so much money invested in it. Chevy check your status.
  • my 02 impala runs fine, but will shift rapidly back and forth between 3rd and 4th gear at middle speeds, especially while on a slight incline. once it gets through this range, it will level out nicely over 60 mph. does anyone have some incites on this problem?

    Have you tried replacing the transmission fluid and cleaning the magnet/pan?
    This often works wonders on GM transmissions. GM lies about the fluid change interval. Don't let it go for more than 50000 miles. Those sticking components get smooth again when fresh fluid cleans the varnish off.
  • I own a 2008 Impala that I have had concerns about the transmission and clutch since I bought it. I have not had a clean transmission that includes the button on the gear shift not fully coming out in any gear and being able to switch gear without needed to push the button in.

    Recently, I cannot remove the key from the ignition after shutting down while having the car in park. I can leave the key in the ignition and remove everything else from the key and lock the car using the remote, but the key remains in the ignition.

    What can I do to remove the key? Also is this covered under warranty since the car has about 85,000 miles? Is GM willing to remain on future car purchase lists for my consideration?

  • I purchased (financed) an 06 Impala LTZ, and man, I tell ya, I thought I got a bad lemon, but after reading all these issues regarding the transmission, I see it's not just me. Oh, my transmission shifts normal, and smooth. My issue is it tends to stick when you put it from reverse back into drive. There's about a 3-4 second delay, at which most times, I'm already trying to drive, and the car lurches forward with a really harsh kick to the transmission. I'm on the edge with this transmission one day just not going into gear anymore.
  • Scan it and check fluid first. These pumps are known to fail!
  • I have had transmission slipping problems with both of my 2008 Chevy Impalas.

    They both have less than 70,000 miles on them. The same problem. Slipping when getting started. When it's cold it's happens more.

    Are these cars still covered by a warranty?

    Does anyone else have this problem?
  • I own a 2005 Chevy Impala, and it has recently started having transmission problems. Occasionally the transmission would clunk when put into drive, but now the worst problem is the transmission has been slipping for approx. 4 to 5 days, then earlier today, it would not move at all after I was stopped at a red. I had to push the car off to the side of the road, then I had it towed. After the tow truck driver dropped it off at my apartment complex, my daughter, boyfriend and I pushed it into my parking spot, while doing this we had to push it backwards in order to get it parked in my spot straighter, so I put the car into park so it would not roll too far backwards, when I did this my boyfriend notice that it sounded like it shifted. I went through the gears and low and behold it was shifting in Park, Reverse, and Drive, but not 3rd, 2nd, or 1st gears. I put it into Drive and pulled it into my spot with no problems at all. I have not driven it any where yet and do not plan on driving it any where other than the repair shop tomorrow.

    Does anyone have any suggestions for a single female, with no money to spend on a transmission, or any kind of auto repairs for that matter?

    From reading all the forums that I have read so far, it seems to me that GM should be held responsible for all these transmission repairs that Impala owners are having to have done, has anyone filed a class action suite against them for these issues?
