Hello guys
So after a while of driving and come to a stop my 05 grand prix base model slams or bangs into gear after a few seconds of what feels like no power. Ive been told it can be a bad torque converter or sensor, the forward apply piston seal to a shift soliniod.
I have put in the trans go shift kit in, changed the fliter and fuild as well as a bottle of lucas trans fix. It does seem to have helped but still does this and also happens from 1st to reverse but doesnt slam just shrudders a slight bit.
