Transmission Control Module

The transmission control module (TCM) is an integral part of the Mechatronic valve block which is located at the bottom of the transmission, within the fluid pan. The transmission control module (TCM) is the main controlling component of the transmission.

The transmission control module (TCM) processes signals from the transmission speed and temperature sensors, engine control module (ECM) and other vehicle systems. From the received signal inputs and pre-programmed data, the module calculates the correct gear, torque converter clutch setting and optimum pressure settings for gear shift and lock-up clutch control.
