Circuit Description

The transaxle control module provides precise gear shift timing and torque converter lock-up by controlling the operation of the automatic transaxle solenoid valves (Low & reverse solenoid valve, damper clutch control solenoid valve, over-driver solenoid valve, 2nd solenoid valve and under-drivesolenoid valve).

The TCM controls the operation of these five solenoid valves based on input signals from the various sensors (for instance, A/T pulse generatorA,B) and the sport mode & shift limit switch signal.

The transaxle control module has a built-in self diagnostic feature. Refer to the Shop Manual, section ATM, for details.
