Almost the exact same thing happened to me at a drive through car wash yesterday with my 2002 C320. I drove the car in, let the machines do the wash and blow dry cycle. Drove out of the car wash and the trans was stuck in first gear. I pulled over, shut the car off and started again the problem went away until the next stop. Same procedure over again. When I got home, I connected my code reader and got the PO705 code. It's obvious that water got in the shifter from outside the car but from where? The bottom of the car has plastic shields covering the oil pan and part of the transmission. The blow dryers in the car wash are quite strong. Is it possible the water was blown in from the front?
At any rate I have cleared the codes and allowed it to dry out. So far, no problems. I'm thinking if I had fried the circuit board, the problem would not be intermittent.
That's my story for now.
