car sounds fine, runs fine. Reverse and drive bump a little hard, but go into gear, I replaced the conductor plate as the forums say. Got the fluid level correct. But won’t shift still. The dealership told me it was the speed sensor code. What should I do? I’m in Jacksonville Florida.

 

Get the diagnostic codes!! You won't get what you need from a generic OBD II scanner. You will need to use a scan tool that can dig into the Mercedes transmission codes. There are several on the market for about $200 or a little less, or go to an independent shop (NO Dealerships) who specialize in European cars. They can pull the codes and get you started in the right direction. GET the specific code numbers! NOT just an explanation as to what the number means. Without the codes it's just a guess.

 

thanks!!

 

STop going to dealers for service.

 

Speed sensor code = replace transmission conductor plate,
Google 722.6 conductor for parts and howto videos.

 

I replaced conductor plate, and connector. Got fluid right. Someone told me it may be my tcm.
