Chevrolet Impala Transmission Problems

    edited June 2012
    :mad: Last week my impala starting hesitating and shifting hard, so my husband flushed my tranny fluid and changed the filter in hopes to save it. Still felt a bit of hesitation so he changed the plugs and wires, the next day I could still feel a little chug and still got the odd hard shift. No check engine light came on and it still doesn't. Anyhow the next day I took my car to the garage, mechanic drove it around the city and took it out on the highway, no hard shifting and no shuttering? So I drove the car home, filled it up with high test gas, as the mechanic thought maybe I got some bad gas, yeah right, also put in some injector cleaner. Car sat for the weekend, started it tonight and it barely wants to move, checked tranny fluid and yes once again another failed impala tranny, my car has 90, 000 miles on it. I have owned other chevys and my husband drives a chevy, I must say they were well worth the money, this one not so much, very disappointed! To think at one time I dreamed about owning one of these cars, now I realize it was a nightmare! So so frustrated :(

    Well first of all I contacted Chevrolet Canada to see if there was any recalls, there was of course recalls, but none with my VIN. So I have contacted some transmission specialist but they will not be able to look at the vehicle until next week.

    I have a 2003 Chevy Impala and so far my power module had to be replaced(which is the brain to the car),my coolant systems and now aamco is telling me I need a tranny replaced which is $ car ONLY has 80,000 miles on it there should be a recall on this tranny.NEVER again will I buy a gm.I am very upset and want to know how I can go about getting it recalled.
  • I also own a 2003 chevy impala, 3.4 ltr with optional traction car was doing pretty much the same thing, but my front bearings were getting noisy, so replaced is a bearing hub assembly that includes the sensors for the traction control if your car is so equipped.....took care of that problem, it WASN'T the transmission.....hope this helps

    I am so with you on this one, mine is currently in the shop re: torque converter which is going to cost me $1800.00-$2400.00. This is the best quote I could find. I have also had to put a water pump, power steering hose, rotors and a new muffler on mine. My car is a 2006 LS, I really wish I would of never bought it!!!Oh and it has 90, 000 miles on it.
  • crappycarcrappycar Posts: 1
    I have a 2006 Impala that just hit 100k miles, I've had so many problems with this car starting with the throttle and the water pump going out at the same time when it was 3 years old, now culminating with the fact that they now think the transmission is bad. I am not a car expert, but I do not think a transmission should go bad in only 100k miles and all the people I talk to say the same thing. However, now that it's happened to me and I have done some research, I see that apparently this is a known issue in these cars and I can't believe that with complaints going back years and years that GM has not done anything about it. I called Chevrolet to see if there was any recourse and was told to take it to the dealership and pay for diagnosis ($85 I'll never get back), I was told that if it's the transmission and it's caused by "normal wear and tear" then the cost would be on me and that if the issue is caused by "manufacturer defect" the car is out of warranty, but they might be able to help. I honestly feel like she was just "customer service talking" me. How could it go out for normal wear and tear after 100k miles? It's not like I'm racing this car, I rarely drive it over the speed limit, and the quality of GM transmissions is to only last 100k miles? That's ridiculous and GM should have better standards.
  • reedgirlreedgirl Posts: 8
    I also called GM and they weren't much help! However if you have a Mr. Transmission in your area, they will do a free dianostics. This is where I chose to take my car (I am in Ontario though). The tech actually called me back today to tell me my car needs a boot on the axle, new cooler lines, a mount and a transmission rebuild (its the valve body). Total cost $2645.00, plus tax! All I can say, is this will be my last GM!
  • wow I would have love to join this group
  • Hello Everyone, I have a 2004 Impala. Oh boy! It started the day after I purchased it 19miles used. The passiliock, gas gauge,wipers, temp gauge that was funny though on the pa turnpike the gauge shot into red suddenly with no smoke I got off the nearest exit and a young man was kind enough to help out by saying ( before I could tell him what the problem was) your temp gauge fooled you huh. lol he had a impala same year same color. Well, then the transmission repaired into the third year. To speed things up, other issues, like the latest, starter and now transmission again by the way the transmission has been slipping for the past 2 years with that hard shift on take off. Is this an issue that isolated to only a few thousand that I'm seeing on the internet? Why can't we all get together and make GM face the problem like the young man asked me to do back then on the pa turnpike and I thought! " he's a fool". Boy if I could see him now. So everyone what do you all think about this idea and how do we get started.
    I have looked online for petitions and class action against GM and this trans issue and found none.

    We don't permit using the forums to organize legal action. The BEST way to get similar complaints compiled all in one place is to report them to the NHTSA at

    It wont do you any good to go after GM with all the issues on cars from before 2009 when they reorganized out of bankruptcy. They already got out of having to be responsible for the 2006-2008 Impala rear suspension problem and got out of the recall by claiming that it was a poor design from the old GM who went bankrupt. The new GM is not responsable for problems created by the old GM.
  • Kirstie_HKirstie_H Posts: 11,081
    That is, sadly, mostly true. I believe some recalls have been issued on earlier vehicles, but legal action on pre-2009 models will most likely result in failure due to the reorganization. It is still worthwhile to go to and report, but legal action would likely be a waste of time.

    :sick: I swear this car is possessed!!! I bought this car not even 2 years ago with 56, 000 km on it, so far a water pump, rotors, 2 sets of tires, front end alignment, total tranny rebuild, power steering line, tranny lines, tranny mount, axle boot and now it is in the shop once again! Just got my car back one week ago, had the tranny totally rebuilt $3158.18 (ouch), then as I am driving to work Friday morning my gauges start to go crazy (going up and down, then they wouldn't move at all) door locks clicking but not moving and then the car starts chugging! So it once again is back at the garage, where they say the computers aren't comunicating with each other, but haven't figured out why, I so wish I would of left this car, where I bought it!!! :lemon: Soon I will be car bankrupt thanks to this piece of crap!! Oh yes and I called Chevrolet and they may have covered some of the cost, had I took it to a dealership and not a Mr. Transmission! I will never ever buy another Chevy as long as I shall live!!!
  • cobcob Posts: 210
    Based on the gages going crazy it sounds like you may need a new battery. It could also be a result of the transmission shop not reprogramming the computer for the trans correctly and it is causing the issue but most likely you have described the symptoms of a battery that is failing.
  • My car just started the hard shift from a complete stop to take off. Now that I have read all these posts it does sound like something we should fight together! What are your ideas for pursuing this?
  • Kirstie_HKirstie_H Posts: 11,081
    The best way to get all similar complaints compiled in one place and noticed by those who have any authority is to report them at That's how to get to the NHTSA vehicle complaint system.

    Since we don't allow organizing legal action in the forums, that's definitely your best route.

  • I have had several major problems with my 2006 Impala. I am starting to think I have a lemon.... And after reading some of these posts, I feel I'm not the only one. I am interested in persuing something regarding this and would like your help,and anyone else who is having the same car issues.
  • Good afternoon ocampomom,

    We're sorry to hear that you're having difficulties with your Impala. Have you tried working with Customer Assistance already?

  • WOW! Sarah,
    I hope GM helps at least one out of the many thousands of families who have been ripped off, put in danger and out right disregarded by GM.
    My sister and a friend went car shopping last week, they called me to ask if I like my car well needless to say, no I don't. I told them to keep far away from GM, with an explanation. Since 2005 I have been keeping record of how many families I kept from being robbed at the pockets of GM #31.Repair after repair, car note, family and a down economy. Thanks GM from all the GM SUPPORTERS WHO NO LONGER TRUST DOING BUSINESS WITH YOU!, my 2004 impala is paid for and I would never ever buy another. :lemon: :sick: :surprise:

    I've owned a base model 2004 Impala-purchased new from Sherwood Chevrolet. For roughly 3 years now it has slipped from 1-2 gear from a stop. occasionally the car will shift hard throughout all the gears while i am driving. Sometimes I swear the bottom of the car is going to drop out- thats how hard the 1-2 shift is. a while back I had it assessed (for over $100) and they decided to perform a "Reset procedure on the shift points" This was supposed to "Re-Learn" of a drive and shift accordingly. The Chevy mechanic also claimed "He shifted properly when he drove it". Welllll guess what? It doesnt, and didn't. Wave goodbye to $800!
    The car has now also started to display the security or "passlock" light and this often engages and doesnt allow the car to start..I just get an electronic sound when I try to turn the engine over. This happens more during a humid and hot day, but does occur during the winter. Sometimes 3 times a day! i've called the dealorship to inquire about this but I always get "transferred to someone who knows more"...coincidentally nobody picks up the line and my messages are not returned.
    The fuel guage has also stopped working and im not sure if this is related to the Passlock security system (perhaps the worst chevy invention ever conceived) or another problem.
    I've loyally gone to the same dealorship and related service centre for the past 8 years with this vehicle and all ive gotten in return are unresolved problems to add to the growing list of new problems. This car has been entirely unreliable and a financial pit. I am extremely unimpressed and dissapointed in chevy. This car has under 98,000km on it with regular service. I find the problems unacceptable but the service advisors just talk to me like im an idiot....of course while handing me another $1500+ bill. I am just waiting for the day the car just quits on me for good..what a joy
  • I have a 2007 Impala LTZ, with 56,000 mi and the same slipping problem that you all are having. Took it to my local Chevy dealer and we could not duplicate the problem, no matter what we tried. Two months later my wife and I went up north to Mackinaw city, and in stop and go traffic, it started to slam in gear at take off. Took it back to my dealership with an Edmunds forum in hand, and they said they are starting to here more of this problem, and they will rebuild the trany. Word of advice, on any new model car like mine. Budget in the best extended warranty they offer as I did. Tranny rebuild $2,500 Extended warranty $1,000 do the math.
  • Extended warranty worked for you, my car was 20,000 km over the extended warranty. It only had 90, 000 miles on it. Needless to say I'm still fuming!
  • Good morning hondo2001,

    We're glad to hear that you've been able to get a resolution worked out with your dealership (and hope that your trip to Mackinaw wasn't too interrupted by the transmission matter).

    Is the repair in progress, or do you already have the Impala back in your possession? Let us know how it's running once you have it back!

    Sarah, GM Customer Service
  • Hello,

    I have a 2003 Impala Ls and i am also having a transmission problem, I purchased the car at a used car dealer with 125,000 miles and everything on the car works but i'm experiencing a hard shift issue, I have read post after post and joined so many forum's and it seem's that everybody that own an impala are having similar transmission issues. My impala is currently in the repair shop getting checked out as i write this post...My mechanic also said that "GM" need to step up and do something about their "faulty" transmissions! :mad:

    P.s. The only happy ending is if my transmission need's to be replaced the dealer cover's the cost :shades:...Thank God...LOL
  • Hello Hollywood 13. My 2008 Chevy Impala SS has the same symptons as yours. What did you find out was wrong with yours?
  • Hello rbell5,

    Hopefully you'll hear back from hollywood13 soon! If we can check into anything in the mean time (recall or warranty information, for example), feel free to email us the last 8 digits of your VIN at [email protected]

    Sarah, GM Customer Service
  • have same problem with my 2004 ss impala with 86k miles intermittent tranny slipping.was told needed a rebuild at about 2500.00.have been driving for 1ok miles now hasnt gotten any worse.will be buying a Toyota next time gm needs to have recall on this issue.keep everyone informed about what fixes the problem?thanks
  • Took car to GM Dealership Saturday morning. Bad ground on Body Control Module (BCM) showed 42 code errors. Fixed Ground on BCM rechecked codes, 2 came back. One was for the driver side HVAC actuator and the other was for a fuel tank pressure sensor. Cost $56 dollars and some change for the HVAC actuator and 70 something dollars and some change for the Fuel Tank Pressure Sensor. $35 misc shop fees. Total $1014 and some change, a over $700 Labor.... I am in the wrong profession with labor that high, another reason this country is in the shape it is in......
  • Hello,

    I definitely agree that "GM" need's to have a recall on their transmissions :lemon: , I was told by "GM" customer service that since my Impala is 9 years old they couldn't help with any financial cost..."GM" is a joke :mad: ! The next car i buy will definitely be a import :) ...I will update everyone soon when i find out a fix for our Impala's :) !

    P.s. A rebuilt tranny for $2500.00....WOW :mad: !!!
