I had the same issue as you are having. It lasted for over a year. The problem that Terry speaks of was part of the problem. The largest part was, believe it or not, a faulty clutch. The pressure plate was warped.
Try this test: Put your car in gear and hold in the clutch. Floor the throttle. If you feel a slight lurching in the drive train (like bumping0 then you have the clutch issue. I had mine replaced under warranty and the problem was gone. Later in the year, my bolt (Terry's description) sheared off and fell into the tranny. My shifter had no connection to the tranny at that point. The story gets even better, but that is another post.
