i got a 97 z/28 auto, it has a problem. Whenever you go long distances at constant speed of around 70mph for a while, right when u have to slow down for lets say a stop light, you start accelerating, when the car shifts it kinda throws you back in the seat, like the tranny thought i was at WOT! it's the weirdest thing, hopefully some1 can help me fix this ailment.
