Chevrolet Impala Transmission Problems

    Having the same tranny problems with a 2008 LTZ Impala. Trans slips or shutters when starting out from a stop. Can get real scary when trying to
    accelerate into high speed traffic from a full stop. Problem started (intermittently) shortly after 30,000 miles. Vehicle has been to the dealership 4 times to address this intermittent slip or shutter and each time
    I was told that there was nothing wrong with the transmission. Dealer said
    that maybe its the way I drive and even suggested I try a different brand of gasoline!! My wife will no long drive the car because she feels unsafe due
    to the fact that the problem is intermittent and seems to be getting worse when it happens. I've have been a GM person all my adult life, but after the
    lack luster response from the dealership, I will be looking elsewhere for my
    new "ride." For what its worth, I have a 2004 GMC Denali that needed a
    trans rebuilt at 47,000 miles. GM doesn't build them like they use to and apparently don't want to stand behind their products either!! Very sad!
  • Hi All,

    I've a 2006 Chevy Impala LS was driving fine and my wife had a fender bender. When she was pulling off of the service station lot a car back-up into the front drivers side. The car ran fine. She park it in the garage and the next morning it would not go in any gear. You can hear it click when shift it but want move at all. Would this happen from the accident or is something else would cause this all of a sutton?

    bought on o4 impala last fall and now the tranny is acting up. When i start out from a roll or a compete stop the tranny will sometimes hesitate then slam into gear. Doesnt always do it but it seems to be getting worse and doing it more throughout the driving range. A tranny shop pulled the pan off and it was sludged up on the bottom of the pan and he said that that meant that there were parts wearing out.
    According to carfax history the tranny was flushed at 70k but no filter change.
    The car now has 96k I bought it at 92k. I hope its that pressure modular but the tranny guys are saying that it needs to be overhauled at $1500 -2000. May consider a GM factory rebuilt or a Jasper???

    anyhone else having this issue??? I suppose GM isnt doing anything about it???
  • also have 04 impala.having the same problem was told it was the pressure module or a electronic part by a tranny shop was told 2500.00 for a rebuid 12month warranty only have 78000 knows about problem no recalls the speedometer also seems to be a issue with this car mine got stuck at 45 mph had replaced for400.00 dealer said known problem but on speedo recall is only on the 04 suvs.
  • Hello, I am a 05 Impala owner, I purchase it in 08. It only had 35000 miles. Starting having problems within months but would periodly disappear. It does not happen all the time but is getting worse. When going into passing gear there is a strong kick,also going up hills. I have put gas treatment changed filters and transmission fluid. A friend of mine told me that her Impala's transmission was slipping. She said that all Impalas were doing that. If anyone can hep,or give me a number to GM would greatly appreciate it.
  • mine has been doing it for about a year and mine is a 2004 i had a tranny flush but come to find out they didnt even change the filter which is the most important thing. they said that could possibly fix it if not it needs rebuilt, also my ABS system and my traction active is now messing up they said if i replace my hub bearing on the passenger front that will fix the problem because the sensor is bad, its 300 per side but i can buy the part for 90.00 and my dad can fix it so hopefully i dont have to spend a arm and a leg.
  • have same problem with tranny still not fixed only slips abs and traction light came on had a problem with the sensor on the brake master can try to unplug clean and plug back in sometimes its just a bad connection.

    I have the same problem on a 2006 Impala LT3 model. It started at about 70k and now I'm at 80K.
    I spoke to my mecahanic at the dealership where i purchased it and he admitted there is a known issue with the transmission. There is an intenal valve body piston in the transmission. The bore of the piston tends to wear out causing improper fluid pressure to flow through causing the hesitations and jerking. This could be fixed by replacing the piston if the damage is not too extensive. If not then a rebuilt or certified new transmisson will run $2700-$3200. If this is a known issue then GM/Chevrolet should be doing some kind of full re-call or at least a partial re-call on this issue. This not good. I have had tree major repairs to this vehicle in the last two years. First it was the cooling mainfold and water pump. Then the rack and steering pump. Unfortunately the rack and pump went out after warranty. Now I'm stuck with this issue and still have balance due on my loan. If GM wanted to take our money for a bail out then they need to return the favor for the faulty labor on this car!!!!
  • I minds well chime in. I have a 2005 Impala we bought used with 50k miles on it. Ran great but started noticing an occasional slip after coming to a stop and then would 'chunk' in with a hard jolt. It seems to be happening more often now. There are literally thousands of stories out there about this known issue (not only in this forum). Any news on a recall for this? Come on GM. Do the right thing :-)

    I'm suprised someone hasen't been hurt in an accident related to this problem. I could easily see someone sitting at a stop sign while waiting to turn into traffic...they get on it to blend into traffic and then find themselves 'LAUNCHED' into the wrong lane. Almost happened to me yesterday. Scary.

    I own a 2004 and have had almost every common issue all the other Impalas have had. I take very good care of my car, etc. Transmission has been replaced due to the hard shifting and finally it gave up the ghost, clunk in steering column, gas gauge died (replaced sending unit, wasn`t the problem though), multi switch on column for high beam headlights is touch and go, I don`t use brights because I may lose any headlights I have for a few seconds. Subframe bushings replaced, both front wheel bearing hub assemblies, blower motor and recently a bad Body Control Module...yada yada.
    I would junk this car but I borrowed on it to repair it, everything is new but the motor.....uh oh!
  • I have a 2003 Chevy Impala, and yesterday as I was turning at a red light, my car wouldn't take off. It was like it was stuck but it slowly accelerated. As I proceeded to drive it, it finally picked up speed. But when I stopped again and proceeded to go, it done it again. I took it to a friend who is a mechanic and he says its the transmission going bad. I don't want to spend unnecessary money in getting it fixed. Any ideas on what it could be?
  • it could be ur cadillaic converter that is what was wrong with r impala

    Well, I finally came to a decision and got rid of the Impala. I am so disappointed with GM for putting out a car with so many problems and no recourse except to not buy another GM product. My last 3 cars were Chevy's...all were fraught with problems. My new car is a Toyota.
  • Renderspud,

    I am sorry to hear that your Impala wasn’t a satisfactory vehicle for you. I hope that you are happy with your new vehicle.

  • Sarah,

    I have a 2005 Impala as well and it just started having transmission issues. The same problems that people before me have been discribing. If this is such a common problem among Impalas then clearly there is something wrong with the design of this transmission. I have been a GM and Chevy fan my whole life. My dad has had chevy trucks his whole life. He still has his 1970 chevy pickup, and it still runs like new. My first car was a 1973 chevy 3/4 ton pickup with a big block 454. That truck never gave me any problems. I still have a 2001 chevy silverado 2500 and it has almost 200,000 miles on it and it's never given me a problem. There is NO reason why a 2005 Impapla with barely over a 100,000 miles should have a transmission failure. If it was only me this happened to, then maybe I did something wrong or just got very unlucky. But for this severe of a problem to be happening to this many people there has to be a design problem. This needs to be addressed. If GM wants to make it up to their customers then they should put out a recall on all Impalas having these transmission problems and offer to fix the transmissions for free. If they don't do something soon to win back their customers more and more will continue to leave GM for other manufacturers. And typically they're leaving and buying foreign cars. In an ecconomy like we have now we need as many people buying American as possible. All we as customers want is for GM to make reliable vehicles for us, as they have done for so many years, and if a mistake is made do whatever is necessary to fix it. As I said before I have been a GM fan my whole life and I want to see GM once again be the brand that everyone is proud to own.

  • Mseabert,

    Your loyalty to GM is much appreciated, and I want to thank you (and all posters) for writing and voicing your concerns. I have documented this thread in the forum for GM’s consideration – thank you (all!) for contributing to the discussion. If we can ever be of assistance, either helping work with a dealership towards a resolution or looking into warranty/recall information on your vehicle, we’re only an email away.

  • I too have an Impala. It's a 2002 that I bought in 2005. First the catalitic converter clogged right after buying was under warranty so no big deal. Now with less than 100,000 miles the transmission went. I experienced many of the same "symptoms" as listed above. Had the transmission replaced and now find out the radiator is cracked. Very very frustrating...don't think I'll be buying another GM!!
  • Bricon9799,
    I see that you’ve had your transmission replaced – how are things operating now? I’m sorry to hear that your radiator has cracked, and can understand how this is frustrating.

    While I cannot make any guarantees up front, we are available to assist you in working with a dealership towards resolving this concern, or to look into warranty/recall information specific to your vehicle. Please email us your name/user name, contact information, the last 8 digits of your VIN, and your involved dealership.

    All the best,
    GM Customer Service
  • I too have had transmission problems with my 2000 Chevrolet Impala. I had to replace it in 2006 and here again I NEED another one with 100k+ miles. Same problems as previous complaints on here. I had a mechanic to look at it and was told my first gear is gone. I have always purchased chevrolet cars, from Corsica, Lumina and now Impala. Obviously, there is something major wrong with this car and working components. I will never purchase a GM ever........... Very sad
  • I also have had Transmission problems with my 2001 Impala. Whenever i go to take off it plugs along and has trouble accelerating and when i finally get up to speed if i even do, I have to stop at a light or stop sign and start over again. This is extremely frustrating. Reading through these posts it amazes me that with so many people having similar problems nothing has been done by GM to remedy the problem.
