This answer was rated:

2003 SL500 MB Hard shift from 1st to 2nd. Automatic trans fluid found in at control module. Leak a transmission repaired, cable tween trans and tran control module cleaned by dealer, air hose?. I cleaned oil out of module with elec solvent. Dealer says module check out ok on his computer. still have shifting problem. When problem 1st started I had a speed sensor fault code borderline but the code no longer pops up. Is problem other than the trans fluid leak , or should replace module?

your spped sensor may also be failing intermitently, an even more common problem is the electronic conductior plate which is on top of the valve body and transmit speed sensor signals to the control module.
