Components | Function
Pattern Select Switch | Selects the Power mode or the Normal mode for shift and lock–up timing.
Crankshaft Position Sensor and Camshaft Position Sensor | Detects the engine speed.
Park/Neutral Position Switch | Detects the shift lever position.
Stop Light Switch | Detects if the brake pedal is depressed.
Throttle Position Sensor | Detects the throttle valve opening angle.
O/D Main Switch | Prevents up–shift to the O/D gear if the O/D switch is off.
Cruise Control ECU | This ECU prevents the transmission from shifting into O/D and prohibits lock–up control when the vehicle's speed drops below the cruise control set speed parameter.
No.1 and No.2 Vehicle Speed Sensor. | Detects the vehicle speed. Ordinarily, transmission control uses signals from the No.2 vehicle speed sensor, and the No.1 vehicle speed sensor is used as a back–up.
