Transmission Control Systems: Description and Operation

PURPOSE
The electronic control system for the A541E automatic transaxle provides extremely precise control of the gear shift timing and lock-up timing in response to driving conditions as sensed by various sensors located throughout the vehicle and in response to the engine's running condition. At the same time, the ECM control reduces vehicle squat when the vehicle starts out and gear shift shock. The electronic control system is also equipped with a self diagnosis system which diagnoses malfunctions of electronically controlled components and warns the driver, and a fail-safe system which makes it possible for the vehicle to continue functioning when a malfunction occurs.
