E320 Valve Body Replacement

Question by W211 posted 6 months 3 weeks ago in Mercedes-Benz

I have a 2002 E320 and it seems that the valve body or conductor plate are deffective. I am planing to go ahead and replace the valve body. Does it need to be coded afterwards? I know on the 722.09 transmission the TCU is installed on the conductor plate but how about the 5 older 5 speed transmision. Any help is greatly apprecitaed.
