The automatic transmissions 6HP19TÜ, 6HP26TÜ and 6HP32TÜ are mechatronic systems that unite both the mechanical system (transmission) and the electronics (transmission control) within the transmission case. In the same way as automatic transmissions used to date, the adaptive transmission control adapts the shift characteristics of the comfort program and sport program to the driver's demand and the driving situation.
