I have a 94 S500 with a rebuilt transmission and my car jerks backwards when I shift from Park to Reverse or Drive to Reverse. This is before I take my foot off the brake - so the car does not actually move in its footing - just sort of jumps backwards. It happens more than 50% of the time I put the car in Reverse. Anyone have a similar problem?

Note it does not happen when I put the car from Reverse to Drive or to Park.
