Transmission Control Module (TCM)

The TCM receives input signals from various sensors, switches, and other control units to processes data, and outputs signals for the A/T control system. The TCM controls the shift solenoid valves and the clutch pressure control solenoid valves in the valve body assembly to perform the hydraulic control, the shift control, and the lock-up control. Also, the TCM sends the enabling signal of the auto idle stop system to the PCM.
