I have a Mercedes 2000 c280, stuck in the limp mode.  I replaced the conductor plate and the adapter sleeve.  I got codes p0715 and p0758. I then replaced the conductor plate and adapter sleeve again and all of the solenoids. I cleared the codes . It is still in the limp mode and the codes have reset and is showing p0715 and p0758.  I am at a loss.

Sorry to hear about your troubles. When you look at the instrument cluster, next to the clock you should see the gear you are in. So you should see P, R, D as you move the shifter. Do you see any of these?

Did you spill water on the shifter recently?

Your issue may not have been the valve body. But hey, replacing the conductor plate, adapter sleeve and doing a transmission flush doesn't hurt. :)

no I haven't spilled any thing in the shifter.  how easy is it to replace and do I need to have any reprogramming afterward.

also why would I get a p0715 or p0758 code,  you're probably right I was just wondering.  a real mech once told me that sometimes you have to put down your scanner and diagnose the problem. Thanks

No it does not need programing for that year. With that said, it would be good to read the old shifter and transfer to the new but regardless it should work.

Did you clear the codes from the transmission control unit? You need a scanner that will clear TCU codes. For that year you may need a scanner with the 38 pin connector.
