Transmission Control Module

TCM receives information from various input devices and uses this information to control solenoids on transmission valve body for transmission shifting and torque converter lock-up.

TCM contains a self-diagnostic system, which will store DTCS if failure or problem exists in electronic control system. DTC can be retrieved to determine problem area. See DIAGNOSIS & TESTING  . TCM is located under left side of instrument panel, above accelerator pedal bracket.
