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.

Outline
While a vehicle normally turns safely in response to steering operation,
there are instances when the limits of tire lateral grip is surpassed due to
road surface conditions or vehicle speed, and the influence of evasive steering

A hot engine can cause severe burns. Turn off the engine and wait until it
is cool before servicing.
CAUTION:
If the camshaft is rotated with the timing chain removed and the piston at
the top dead center position, the valve may contact the piston and the engine ...
