Transmission Position Sensor/Switch: Locations

Electrical and Electronic Components and Component Locations

Mechatronic unit, Transmission Control Module (TCM) (J217), Multi-Function Transmission Range (TR) Switch (F125), Transmission Input Speed (RPM) Sensor (G182) and Transmission Output Speed (RPM) Sensor (G195)





Location: The Mechatronic unit is bolted to the underside of the transmission housing and is covered by the transmission oil pan.

The Mechatronic unit incorporates the hydraulic control, the Transmission Control Module (TCM), the Multi-Function Transmission Range (TR) Switch and the sensors and actuators as a complete synchronized unit. Included are:

• Transmission Control Module (TCM) (J217)

• Multi-Function Transmission Range Switch (F125)

• Transmission Input Speed (RPM) Sensor (G182)

• Transmission Output Speed (RPM) Sensor (G195)

The "Mechatronic" unit can only be replaced as a complete unit.

Tiptronic Switch (F189)





Location: Tiptronic Switch (F189) is integrated into circuit board of symbol insert, which is located in shift mechanism cover.
