2. ELECTRONIC CONTROL SYSTEM
The electronic control system for controlling the shift timing and the operation of the lock±up clutch is
composed of the following 3 parts:
(a) Sensors: These sense the vehicle speed and throttle position and send this data to the ECM in the form
of electronic signals.
(b) ECM: This determines the shift and lock±up timing based upon the signals from the sensors.
(c) Actuators: Solenoid valves divert hydraulic pressure from one circuit of the hydraulic control unit to
another, thus controlling shifting and lock±up timing.
