Could this be the transmission clutch solenoid?
Run car at low rpms and right when it shifts into overdrive rpms bounce up and down about 500 rpms, i am not getting engine code and only code i got was for MAF sensor replaced that and that was not the problem!
the tranny shouldn't shift into overdrive until the car is going over 60 mph,sounds like its time for a rebuild.
Well idk cuz it shifts smooth and doesnt slip or anything. Also it shifts into overdrive around 50 55 i meant when im running low rpms by not accerating heavy and hit bout 50 is when the rpms bounce, do u know of anything else it could b? Mayb tranny fluid and filter change, fluid looks good?
what did you find out was the problem. my 2006 grand pric gt supercharged is doing the exact same thing.
