Electrical Components In The Transmission

Installation position







The engine can only be started with the selector lever in position "P" or "N".

Multi-functional switch

The multi-functional switch (MFS) has the task of notifying the transmission control module or the transmission of the position of the gear selector.







Input and output rpm-sensor

The input rpm-sensor for the transmission is mounted on the oil pump and the output rpm-sensor is mounted on the transmission housing.










The input rpm-sensor for the transmission measures the engine speed directly at the transmission input shaft. The output rpm-sensor uses the ring gear on the rear planetary gear set. These signals are sent to the transmission control module. Upshifts and downshifts are performed, the lockup clutch is activated and the engine torque is influenced according to these signals.
