Hello all,
Earlier this year I purchased a 1998 E320 and it has been a great car. It has 230000miles on it, but still runs great. Recently the transmission began acting up, transmission occasionally got stuck in "Limp" mode and caused a check engine light. I have a OBD II scanner, and was able to determine that it was the P0715 Input/turbine speed sensor malfunction. Based on my internet research, and the symptoms I was seeing, i determined it was the transmission conductor plate going bad. I got a new Mercedes Benz conductor plate, as well as new filter, pan gasket, fluid and a dipstick so I could refill and check the transmission fluid. I also read that sometimes, if a drink is spilled in the gear selector assembly that it can give false outputs and confuse the transmission computer, so I completely disassembled that/cleaned the electronic contacts with alcohol and lubricated the moving parts. (the electronic contacts looked fine, no evidence of a drink spill in there.) Everything is back together now but the transmission is stuck in second gear when I put it in drive. From what I have been able to glean from various posts, the transmission is now stuck in limp mode, and there is no way to clear the codes with a standard OBD II code scanner (I have tried also, and it does not work). I also tried disconnecting the battery for a few hours to see if that would clear the transmission, but that did not work either. It seems that I need to clear the code with with a 38 pin MB scanner.
So my question is twofold, 1) does this sound right? even after replacing the conductor plate (And plug) is it normal for the transmission to stay in limp mode? and 2) is there anyone local to Hopewell, NJ who has a 38 pin MB scan tool that would be able to help me reset the transmission? Am willing to travel, but since the car is stuck in 2nd, I can't go too far or get on any highways, which is why I was hoping I might find someone close.
Thanks for reading
