Transmission Control Module (TCM)

The TCM is an assembly of an electronic module, sensors, and electrical actuators. It combines a control module and two electric motors for gear shifting. The primary function of TCM is to collect incoming data signals to control the transaxle, perform the interpretation of incoming data signals, communicate with the periphery and connect the electrical and mechanical contact to the signal transmitter and actuating elements. Vehicle and transaxle interface is achieved via two connectors; vehicle and transaxle connector. The transaxle connector plug is located at the TCM and is the electrical connection between the TCM and the clutch actuators and the sensors. The vehicle connector is located at the TCM and is the electrical connection between TCM and the vehicle. The TCM is a programmable module.
