  • 85,000 miles


The were no events leading up to the failure. One day we were driving in town at 45 mph and the transmission developed a high pitched sound and two seconds later it dropped to 25 mph. The transmission will have to be replaced at a cost for than the car is worth. The transmission shop stated it is a very common problem with the car due to a large gap between the clutch and the gears.

The traction system was activating for no reason. Service ABS light came on in vehicle. Dealer replaced left wheel hub, including sensor. Problem recurred the day after and the wrong assembly was installed, the correct assembly was installed. One month later problem recurred. Dealer claimed it was a loose connection on wheel hub assembly. Seven months later problem recurred. Dealer now says the right hub assembly needed replacing, as well as the transmission solenoid. Repairs have not been done for the latter because we want dealership to repair free of charge.

My vehicle has a problem with the transmission running rough, nearly stalling, and a 0742 code being activated. The car has 123,000 miles on it, so it is well out of warranty. A local transmission shop stated that the transmission needed to be rebuilt and quoted a price of $1400 to rebuild the transmission. I know that the car has a great deal of mileage on it, but I expect a little bit more for the money I paid for the car. After looking on this web site at the number of complaints and problems people are having with this car/transmission, and seeing that the 4T65E transmission is used in over 20 GM cars, when are you going to do something about GM taking advantage of this before it costs the american public thousands of dollars? anything you can do to push GM to make this problem right would be appreciated. If you cannot the only thing I will do is buy Japanese.

Power train failure: First sign of problem was harsh shifting, had the transmission fluid and filter changed, still had same problem. Before I found the service bulletins on this problem the planetary gears got chewed up by a broken piece of metal, had to rebuild the transmission $1800. Filed complaint with GM, since I did not have it repaired at a dealer (for twice the price) they would not help. Now I have a 2001 Monte Carlo showing the same harsh shifting. The transmission has be flushed by the dealer and they put an additive into the transmission fluid to help the sticky value problem, did not work. There is a pattern here and GM will not stand behind their product.

The caller said that while accelerating to get back on the highway lost forward motion. He said the transmission failed. He was able to get the vehicle pushed off the road. Vehicle was towed. Dealer has not done anything yet. Manufacturer said they were contacting the dealer and will get back to the caller. They were holding off until an inspector looked at the vehicle. Inspector was not a GMC employee.

2001 Chevrolet Impala was involved in a minor accident and afterwards the transmission would no longer function. The transmission had no reverse and had shifting problems. The technician determined that the thrust bearings broke and damaged the sun gear, input carrier and reaction sun gear. The technician indicated the this is a common problem with this transmission and that it's failure was not related to the accident. The manufacturer issued service bulletins referencing transmission problems.

Purchase - May 2003 transmission - May 2003 transmission (electrical wire) October 2003 the car continued to run irregular. On an intermittent basis it would be extremely hesitant taking off from a stop sign or red light. February 2004 - nothing was found wrong with the car although it continued to run improperly. September 2004 - catalytic converter October 2004 - undiagnosed due to Chevy's refusal to diagnosis the car for free after just replacing the catalytic converter six (6) days ago.

2001 chev Impala --transmission failure after 40,000 miles due to a pressure pump being bad. Is this the cause to many reported roll backs " did GM put inferior pumps in their transmissions to cut costs and at the consumers expense "

Transmission failure--2001 Chevy Impala with 45,000 miles--basically no advance notice--stopped at a traffic light, depressed accelerator and transmission took awhile to engage before moving forward. Happened again at the next two (2) lights. Got car home intending to take to dealer in morning. Backed car out of garage--went 5 ft and it would not move further. Pulled forward and able to put in reverse to back out of driveway. Managed to get to dealer. Going to teardown transmission tomorrow. Should not happen on a vehicle with 45,000 miles---90,000 maybe, 45,000 no. This is my 3rd transmission failure with a GM product since 1980. Like their styling but don't know if I can continue to purchase their products.

My husband said that his car was driving poorly for about a month or so before it broke down on a busy road. Since this is the third Chevrolet transmission to break down on both my husband and I we knew that was the problem. As a result we were without a car for about a week. Luckily there was no accident but there very well could have been. The car just died at a red light. Chevrolet replaced this transmission with a rebuilt transmission, because it was still under the original factory warranty. The warranty on the rebuilt part was for only 90 days. Last year when we had to pay for the transmission to be replaced on my 1997 Venture after only 52,000 miles the warranty given was for one year.

Car rolls backward while in drive on incline. Dealer claimed that it is normal. Seems to me that it is a safety problem. Also when shifting from reverse to drive the trans will shift but when I accelerate the trans slams into gear. I have not been able to take car in to dealer as this does not happen every day. After reading other complaints about the transmissions it seems that there is a real safety issue.

I currently own a 2001 Chevrolet Impala ls, 3.8L V6. Before 36,000 miles I took my car to the dealership. The vehicle was running poorly and when it was cold the transmission would slam into gear. Dealer made some repairs and told me the fuel system needed to be serviced. I declined the fuel service at the time and the transmission slamming into gear from a cold start continued. The problem worsened at 47,000 miles. I took the car back to the dealer and after 2 days I was told that the problem was the fuel system service. At 50,000 miles the transmission began slipping severely. I tried to get the car home and it failed to engage while pulling into traffic. I got the car home to perform the 50,000 mile service to the transmission and found a handful of metal in the pan. Had the car towed to the dealership and found out that the transmission was completely totalled. GM only offered to pay for half the repair costs. There is no recommended service before 50,000 miles and I don't feel I should be responsible for the repairs on this vehicle. I have owned it less than 3 years.

  • Automatic transmission

While accelerating from a stop sign, car shook all over and I heard a loud bang. The car would not move at all. I coasted to the edge of the road where I waited for a tow truck. The dealerships service manager informed me after about a week, that my planetary gear had exploded. He also stated that the fluid filter was full of metal shavings. He stated to us that there was nothing that I could have done to prevent this from happening. My new transmission cost me $2200. This car has just 55000 miles on it. It is absolutely insane that I am paying all of this money to repair this car, that is practically new. I have contacted GM's corporate customer service people and they will offer no assistance in this matter. The service I received from them was poor. The case was actually lost once therefore I had to start all over again. The woman who then took over the case bold face lied to my fiance and then back pedaled by saying that there was another case just like mine and the woman just happened to have the same name as me. What a coincidence. In addition to this, just 10 days prior to the transmission's death, I had to replace a catalytic converter in the vehicle.
