mercedes c230 w202
Have a client that had replaced the auto box in his car and still having the same issue where it will change to 2nd gear and then automatically go back to 1st gear and when stopping at the traffic lights, have to switch the car off and start it again to get gears.
Car is currently at the dealers and they have diagnosed the TCM to be faulty.
Can a sec hand TCM be used, dealers say it wont work, why not?
I have replaced an injector on a w203 c220 cdi before and I had to program the injector with the MB star.
I know that the ecu, ignition, key etc are all coded to the chassis thus they have to be ordered from the dealers according to the chassis number.

What I would like to know is will a second hand TCM or ECU not work on another vehicle even if one has the MB star diagnosis and the original TCM or ECU.
Anyone have some further details on this for me?
Thanks in advance
