The Automatic Transmission Control Module (TCM) operates the solenoid valves in the gearbox to provide automatic control of gearshifts and Torque Converter Clutch (TCC) lock-up. Software in the TCM monitors hard wired inputs and exchanges information with the Engine Control Module (ECM)on a Controller Area Network (CAN) bus to determine gearshift and TCC lock-up requirements. Resultant control signals are then output to the gearbox solenoid valves.
