Car lurches when started, but still in "park"

This has happened a couple of times from a cold start, but not always and rarely. When I start the car I can feel a distinctive surge forward, like it is in gear and wants to move froward but the transmission does still hold it still. Normally I have my foot on the brake when I start a car anyway, but I have tested this without my foot on the brake to see if it will still hold still and it does, but certainly wants to move.

My thought is it's something to do with the fluid coupling transmission, I know if you don't let off the accelerator pedal all the way when you come to a stop the car will want to pull forward because of the trans design, so if the transmission somehow coupled when I start it, maybe a throttle linkage is sticking, etc., making it surge? That's all just a guess.

Does this happen in both P and in N? Is there any slop in your transmission linkage? Floor shift? It's remotely possibly that you have slop in the linkage and the transmission thinks you aren't in P or N, but the neutral safety switch thinks you are in P or N....

Maybe your transmission is wonky and this is a strange symptom. I would email your question to Marc at Sun Valley Mercedes, or phone him...

I will have to check in N but I would say no as of right now, just Park. I sit in, gear is P, leave foot off brake (I would normally apply the brake), start the car and I feel it jump forward but apparently the trans is holding it. It's an auto column shift. At one point my shop replaced the white bushings in the linkage and the one at the trans but I do seem to recall there was one harder to reach that he did not access.
