Transmission gear switch in the NEUTRAL position

Except for the different pin numbers at the switch, the transmission gear switch and the shift lever switch operate similarly. Each switch is mechanically positioned with diodes that determine the current flow.

The shift lever switch provides the Electronic Programmable Transmission Control (EPTC II) with information about the transmission control position. The shift lever switch is mechanically connected to the transmission control inside the shift console.

The transmission gear switch sends a signal to the (EPTC II). The signal indicates the transmission gear that is currently engaged. The transmission gear switch is mechanically connected to the rotary actuator of the transmission hydraulic control.
