Impala 6-cyl

  • Automatic transmission
  • 60,000 miles


I have had numerous problems from day one with this car. At 60,000 miles, I had a transmission failure. There was a whining noise that came from the engine compartment, usually at highway speeds in 4th gear, or overdrive. I had the car diagnosed at a transmissioin shop, and was told that it was going to need to be completely rebuilt. This failure could have occurred on the highway, if I had not been vigilant in my investigation of the problem. As a result, I had a huge repair bill, was without the car for 1 week, and had to pay for a rental to drive to work. To correct the problem the transmission and torque converter had to be rebuilt, and repalced. Specific parts that I know of were, the "torrington bearing", which caused failure of a set of planetary gears, and the 4th gear spline. The repairman said that the bearing and the 4th gear spline are of substandard quality, and that replacement parts have purposely been made stronger, and heat treated, because this is a known problem in these transmissoins.60'000 miles is much too early for a failure of this type to occur. Total repair bill was over $2,500.

  • Automatic transmission

Periodic transmission slip from initial date of purchase - dealer could not duplicate when taken in for service, until out of warranty. Reflash E-prom/update done at 75K miles to correct problem. Now at 110K dealer says new transmission is needed as car is exhibiting same problems. Car headlights go out when using high beams. Car has lost all power twice when driving and completely shut off, thus causing a significant steering problem until the car could be stopped. Grounding wires added to see if correction could be made. Lights & car have not quit yet, but transmission continues to exhibit shifting problems with check engine light coming on. When car is shut off the engine light will go out and not come back on and the car will reset it self and run okay for awhile. The car also exhibits a loud whining noise when the slippage / jerking is about to occur. GM will not allow conversation with anyone but a customer service person. All file numbers given to me by GM personnel when car was under warranty are not loaded into their data base, thus nothing can be done, mileage is too high and these things are expected to happen.
