97 E320 51K, have owned since new. At times it seems the car shifts jerky, slipping, occassional thump. Dealer says it's OK, no error codes etc. My other two cars shift flawleesly 99C230K and 2000 500 SL.

97 bothers me enough to think about trading for something else, although I enjoy the car.

Anybody else had this problem with this model year?
