How you do that?
Expert:  Marty replied 3 months ago.

You need to get the car connected to the Mercedes factory scan tool or the equivalent to read and erase the fault codes in every module in the car. The transmission will probably be fine after you erase the codes. The vehicle network problem is most likely a fault with the front SAM. There will be fault codes that point to the network problem. You should also check all fuses in the front and rear fuse boxes.
