Grand Prix SE with the 3.1 liter V6. Problem started with a vibration in the gear shift handle when in reverse. Then, yesterday, I could hear a clicking noise while I was in reverse. Today, I went out to the car to back out of my drive way, put it in reverse and nothing happened. I jiggled the gear shift a little and gave it a lot of gas, and if finally got the gear (after nearly jerking my head off) This happened a few more times, and now I get nothing out of reverse no matter how much jiggling or accelerator tapping I do.
