We are Mercedes specialists and most likely you don't need a transmission. We have the factory diagnostics and can determine your problem. Your vehicle will need to be towed but you may have a bad electronic shifter module. We can be reached at 401-884-2211. Thank you, George! Premier Automotive East Greenwich, RI

you need a good local MB specialty shop that has the correct software to diagnose this car.
