While driving transmission slipped gears and lurched forward. Dealer replaced the original transmission with a rebuilt transmission. The rebuilt transmission also slipped gears and lurched forward. When vehicle was brought to the dealer on first failure of transmission, consumer noticed that the color of the fluid in the trans axle was different from the one in the bottle. Consumer decided to replace the transaxle and fluid after vehicle was driven for a number of miles because the fluid color gets darker. After repair, just after warranty period, transmission blew up then vehicle quit driving forward; transmission technician and could not tell the cause of failure. Consumer spoke to the service department manager and said there was a possibility of an axle bearing or bearing failure.

I have a Chevrolet Impala 2001. Just last week the transmission completely went. I just received word from the transmission shop I took it to. The estimate is $1700. Which is ridiculous for a car with 38,500 miles. GM stated that since it is over warranty there is nothing they could do. Second they stated that the Impala would need to be at a GM dealer for them to even open a complaint with the issue. Why would I take it to a GM dealer to have them tell me sorry out of warranty and then charge me double the quote of a transmission shop. Fool me once shame on you. But fool me twice shame on me. Any advise you could offer would be appreciated.

At 39,000 miles the transmission malfunctioned while shifting into gear, which caused a lurching movement every time. Initially, the transmission problem started at 26K miles. The dealer stated stated that the steering wheel rod needed replacing and lubrication. The difficulty returned. The dealer stated that nothing was wrong. The vehicle had begun to lurch into gear when stopped, skipped gears in reverse, and sometimes would not drop into proper gear.

Purchased 2001 Chevrolet Impala base model. I have 51,000 miles and my transmission went out on me. I had a diagnostic test which showed that there was an electrical problem within the the transmission. A new transmission had to be installed. This cost $2500. There is no reason for a car this age with this many miles to have such a problem, granted the warranty goes to 36,000 miles or 3 years whichever occurs first. I am very upset, and it basically solidified that I will never buy a GM car again.

My 2001 Impala began having loss of power/slipping during acceleration at low speeds around 30,000 miles, dealer looked at car and could not duplicat 2 times. Car scontiued to have the problem and dealer felt that the valve body should be replaced and toe set. At 37,400 miles I was driving along and suddenly loss operation of vehicle whil going through intersection, coasted into gas station tried all gears of car and was unable to move car forward or reverse. Had car towed to dealership. Transmission repair of planetaries and bands was performed that was August 25, 2003. On September 10 check engine light came on and I had it diagnosed at independent mechanic shop and was told that 2 transmission codes were coming up they were 742 and 748. GM extended warranty would not allow repair to be done by any one else but Chevrolet dealership, I took the vehicle into dealership on October 6 and was told on the 9th that they could not duplicate the problem. I will be picking up my car tomorrow and waiting for the next time that the check engine light comes on to take it back to the dealer.

We heard a low rumbling noise while accelerating from a stop, we barely made it through the next major intersection as the car was hardly moving forward any more and coasted to a boulevard off of a major road. The car jumped forward in park when we restarted it and then it would not respond whether we tried to put the car in drive or reverse. This is a 2001 vehicle now in need of a refabbed transmission for a whopping $2700! the dealer never opened the transmission to find out exactly what went wrong (they guess it's the gear set) and they refuse to let us get a 3rd party to examine it. They will charge us a $700 non-refundable core fee even if we return the core to them in a timely manner. Also, the time table for them to return the part to GM just went to 24 hours. Originally they said it usually takes around a week for them to send the part back!

Transmission went out, have to be completely rebuilt. Metal pieces were found in fluid. Vehicle previously in for service due to the pressure modulator in transmission went out. Felt like you were driving and shifting without a clutch if the car was a stick shift. Prior to that, the computer module went out, causing the battery to drain over night and having to jump start it. Before that, the automatic traction control system went out. Found out it was a faulty sensor in the back brake area. Before that, the front rotors were severely wrapped and had to be replaced.
