Hi everybody. New to the forums, hope you guys can be as helpful as my other boards. I recently bought a 2006 Grand Prix. Love the car, love the look, but I have a problem....I think. Whenever I get in the car and shift from Park to Reverse or Drive, it jolts the car. When I am driving though, the shifts are fine. It's not a cold issue because we're in the 80's here lol. Any help you guys can give would be great. If there is anything else y'all need just ask. Thanks!
