The automatic transmissions 6HP19, 6HP26 and 6HP32 are mechatronic systems that unite both the mechanical system (gearbox) and the electronics (gearbox control) within the gearbox case. In the same way as automatic transmissions used to date, the adaptive gearbox control adapts the shift characteristics of the comfort program and sport program to the driver's choice and the driving situation.
