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.
