Mercedes CLS55 AMG W219, How To Replace The TCU

When I searched for a step-by-step video for replacing the Transmission Control Unit (TCU), I could not find one for the CLS. Therefore I created one myself, to help out others who want/need to swap out this unit.

My tuned unit was stamped with:

Siemens A0355457532
KEIN Seriensteuergerat
Speedshift+ Race
Ubersetzung i=2.65
