When stepping on gas car hesitates before engaging into gear. It is intermittent and seems to happen periodically especially after car warms up. It jerks into gear from a dead stop. Was told by the dealer it was the transmission solenoid switch but was not covered. It would cost over $1000 to have it fixed. It's been going on for about 1 year and a half.
I have been looking for a page like this for a few years now, I don't even know how I got to this one. This 2003 Impala started acting like this before the miles I place down, because I bought this car use and my warranty end, I was told I couldn't do anything (the dealer stated) when I come to a stop and then start well try to start the car hesitate and then a hard kick/punch and it would do this only at red lights, stop signs, or reverse. So on 05/12/2010 I bought this car to a auto repair shop they perform a test and it check out two of the shift solenoids for the transmission were bad so they replace both shift solenoids, side cover gasket and transmission filter. Cost me $1,120. 56 with in a week it was still acting like it was never work on. I started asking other owners about there Impala they all said it did the same to them. Now here it is 2012 and my car still kick hard and I can't believe there are no recall on the transmission. I am a little shock my mother use to work for gm -.
I was driving on the interstate anf as I was slowing down the car began downshifting rough. As I increased speed out of the exit the car was "jerking" and shifting very rough. The "check engine" light came on. It took 2 weeks to replace the transmission valve body, wiring harness, and solenoids in the transmission. This car only had 400 miles on it.
