Chevrolet Impala Transmission Problems



  • impalapimpalap Posts: 1
    I've read so many posts all over the internet looking for a solution to this problem and have yet to see someone with a solution posted. I have a 2005 Impala with the same transmission slipping issue when accelerating from a dead stop. Hot or cold doesn't matter. If I have to accelerate on any incline my car begins shaking violently. At times it does so without being on an incline. I recently had all of the solenoids replaced and the problems persist. I took my car to an AAMCO in Baton Rouge and he did mention getting a code or anything. He tried to charge me $575 just to take the tranny out and wanted to dismantle it without knowing what the problem was. Then told me it could end up being a total rebuild for up to $2500. My car is almost paid off and I'd much rather keep it than get a new car, but I'd much rather a new dependable car than a paid off one with monthly repair costs. Does anyone actually have a solution or are all these posts useless?

    I had the same problem. They had to rebuild my tranny and replace solonoids in it. The problem has stopped for the last year it's been great.

    I have a 2008 Chevy Impala with almost the exact problem you had. The car only has 67,000 miles with an extended warranty. I called GM customer service after 2 trips to the dealer. They tried a 3rd time and couldn't duplicate the slipping transmission problem. They also denied that the service bulletin (06-07-30-023C) included the 2008 Impala. Could you please tell me where you received the information that includes the 2008 Impala.

    I have a chevy Impala 2005, that has similar symtoms when your at a stop sign and accelerate, the shift from 1st gear to 2nd gear is hard. The previous owner told me he has struck an object that hit the transmission pan. So I decided to service the transmission, change oil , filtre and upon visual inspection the accumulator assy was damaged . So that was replaced. After the accumulator and service , the transmission continued to shift hard into second gear. So I took the adviced as described in this forum and changed the Pressure Control Solenoid. The results were positive and the hard shift from 1st to 2nd gear stopped. Now this is rather important the scan never showed there was any problem with the pressure control solenoid , so it was the actual advice I took from this forum solved my problem. My car had about 156,000 miles on it before the hard shift started. After I removed the solenoid I did a visual inspection on the solenoid it looked clean but I assume there was micro particles that has passed through the screen and may have clogged it. I would recommend you change your transmission oil on schedule maintenace. I don't think you need to rebuild your transmission , check the cheapest source first like the PC solenoid. I check with a certified shop and it takes 5 hours to replaced the solenoid so do the math and good luck. I hope this helps , and thanks you folks for the timely advice. Saved me an unnecessary rebuild .
  • My impala has transmission problems also along with remote door locks not working. Whining in the right front end and tapping on the right side dashboard area. Not wanting to start when turning the key with the ignition switch. When wanting take off makes a vibration noise and stalls. My mechanic says it might be an ignition switch problem. I am getting afraid to drive my car.

    Good morning hollywood13,
    I'm so sorry to hear that you are feeling fearful of driving your Impala. Is your mechanic with one of our GM dealerships? If so we're happy to follow up with them on this diagnosis. Please send the following information to your name/Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your involved dealership.

  • My 2003 Impala seems to be shifting weird. It is an automatic. It has 90K miles on it. I have taken it to the shop twice and they don't "feel" it. I just had the transmission fluid changed with the filter and a gasket. This morning when I backed out of my driveway (car cold) and shifted into drive and it was a big lull, for lack of a better term. It feels like it loses power when I accelerate from a dead stop or have to hit the gas to speed up. It feels like the power dips down and then catches up. When this is happening, the RPM's are going up to about 3500 and hovering there for a few seconds before it shifts. It feels like its losing power and there is a delay in the shifting.

    It usually happens when the car is hot, but today it was cold, so I'm thinking this is getting worse.

    The problem is that I can't seem to figure out what is wrong with it and the repair shop can't seem to find it. I did not take it to a dealer or transmission only shop, which probably should be my next step.

    I'm hoping someone has some advice for me. I'm skeptical of the repair shops because I often feel, or find out, I'm being taken advantage of and paying for unnecessary repairs.

  • I also have a Chevy Impala mine is a 2006 with only 62k miles and it also has the same transmission problem. I'm also willing to participate in a class action lawsuit as well. Just let me know

    Read my post 341. I examined my PC Solenoid and put an Voltage meter on it . It seems fine but I beleive the solenoid is intermittant and won't show up on any scans. That 's what caused the transmission to shift improperly. So replace the PC Solenoid on the transmission and that might fix your problem. I had to find a second mechanic to deal with it, the first one didn't beleive me.

    :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.

    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.

    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.
