Transaxle Control Module

TCM receives information from various input devices and uses this information to control solenoids on transaxle valve body for transaxle shifting, shift feel and torque converter clutch engagement.

TCM automatically switches from NORMAL mode to POWER mode, corresponding to driving condition in "D" range. Upshifts and downshifts are performed at a higher speed in POWER mode than in NORMAL mode.

TCM contains a self-diagnostic system, which will store DTCs if a failure or problem exists in electronic control system. DTCs can be retrieved to determine problem area. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. TCM is located under left side of instrument panel, left of steering column above fuse box.
