4. ELECTRONIC CONTROL SYSTEM<br />
The electronic control system, which controls the shift points and the operation of the lock-up<br />
clutch, is composed of the following three parts:<br />
1. Sensors<br />
These sensors sense the vehicle speed, throttle opening and other conditions and send these data<br />
to the ECM in the form of electrical signals.<br />
2. ECM<br />
The ECM determines the shift and lock-up timing based upon the signals from sensors, and controls<br />
the solenoid valves of the hydraulic control unit accordingly.<br />
3. Actuators<br />
These are three solenoid valves that control hydraulic pressure acting on the hydraulic valves to<br />
control shifting and lock-up timing.<br />
