Hi everyone..I've been on every Benz site I can find..joined, posted and nobody seems to know jack. So maybe you guys might be able to help. I have a 2005 CLK320 convertible..the car was given to me by a sweet lady who died of breast cancer so I have to make it right. We drove it back to Mo. from Fl. and thank God we made it. So her is my problem...it starts and runs great transmission changes gears right on time, even the manuel side 1 2 3 4 D works great. No problems when it is running, but when you turn it off and come back to start..if there is no P and S in the display...your in limp. You can fool with it and it might work and it might not........ No P and S on display...no work. Turn it off come back later it might work. I just bought a new battery, tran. fluid is full, 13 pin connector is clear of fluid. I'm thinking shift module. Does this sound like it could be that. I a'm ready to drop tran bottom and replace conductor plate next. Any help would be greatly appreciated. Don Akers.
