Control Module: Description and Operation

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 valve, damper clutch control valve, overdriver valve, 2nd valve and under-drive solenoid valve). The transaxle control module operates these solenoid valves based on input signals from the various sensors (for instance, pulse generator A,B).
The transaxle control module has a built-in self diagnostic feature.
