I have a 02 c230 with an automatic trans. I am having an issue with the trans, car does not move in drive or reverse. When I put the car in neutral it will drive forward with very little power. Car starts no problem there is no lights on, no malfunctions reader doesn't find anything. (not a professional scanner) I have tried replacing the conductor plate thinking that may have been the issue but it didn't change the problem at all. When I shift it feels like its going into gear but wont move. any ideas? maybe the solenoids?
