Automatic Transmission/Transaxle: Description and Operation

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 (The Damper clutch control solenoid valve, the shift control solenoid valve A, B and C and the pressure control solenoid valve A and B).

The transaxle control module operates these solenoid valves based on input signals from various sensors (for instance, pulse generators arid oil temperature sensor). The transaxle control module has a built-in self diagnostic feature.
