Purpose/Function
The control valve body controls the hydraulic pressure generated by the oil pump by each solenoid valve. In addition, the oil passages which introduce hydraulic pressure to the pistons for each clutch and brake is formed by the switching of each built-in shift valve.
Construction
The control valve body consists of integrated hydraulic control related parts and electronic control related parts.
The hydraulic control related parts basically consist of the upper control valve body and main control valve body each with built-in shift valves, and the solenoid control valve body with built-in solenoid valves.

Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.
