I have a 92 RS with the 3.1. Whenever I get down on it and it shifts from 1st to 2nd, it gives a semi-hard jerk from the back end. Does anyone know what this could be? Or does anyone else have this problem? Oh and one more thing, I know a guy that has a camaro that he mostly uses for the drag strip, just a little modded 350 and modded trans, and his does the same thing.
