Not sure if this should go in the engine or transmission forum.
I have a 2002 Chevy Impala LS with the 3.8 motor it has 32000 miles on it, when starting from a stop it has good power but does not shift into second when it should and loses power, when it does shift into second it has good power again but has a very difficult time shifting into third, some times I have to pump the gas a few times to get it to shift once it does shift it keeps jumping back and forth from second and third until it gets up to speed then shift into forth, once in forth it will jump back and forth from third and forth until up to speed.
The trans seem solid when in gear with no slipping and the fluid is not burned.
The engine light has come on at times while having these shifting problems, I had it checked and the engine light was due to a misfire, I figured the fuel injectors where clogged so I run a tank of gas and fuel injector cleaner through it with no luck.
I hate computer controlled cars and have no idea what the problem is, hoping some one here can help me out and send me in the right direction.
