ATTENTION!! The 8hp55 comes in two versions, with or without selector cable cord. If it had a mechanical P/R/N/D selector cable, the valve plate then has 2 fewer valves than a standard gearbox without a selector cable cord.

ATTENTION!! The PCB mounted to the 8hp mechatronic TCM is different when the 8hp55 has a selector cable cord.

ATTENTION!! For 8hp55 witch selector cable cord connection between the gearbox and the TCU is different than the standard connection of BMW 8hp45/50/70/75 and 8hp55 without selector cable cord.

*For the 8hp55 Audi, add the missing wires in the internal gearbox harness between the mechatronic TCM and the 8hp round connector.
