Valve Body: Operation: Operation

Outline of the Functions of the Main Components

Component	Function
Torque converter regulator valve	Optimizes the supply pressure for the torque converter depending on driving conditions.
Clutch regulator valve	Adjusts the clutch operating pressure depending on operating conditions.
Pressure regulator valve	Optimizes the discharge pressure (line pressure) from the oil pump depending on driving conditions.
Shift control valve	Controls flow-in/out of line pressure to/from the primary pulley depending on the stroke difference between the stepping motor and the primary pulley.
Lock-up/Select switch solenoid valve	Switches use of the lock-up solenoid control pressure between applying/releasing lock-up and engaging/releasing the forward/reverse clutch (the forward clutch and the reverse brake).
Select switch valve	Switches use of the lock-up solenoid control pressure between applying/releasing lock-up and engaging/releasing the forward/reverse clutch (the forward clutch and the reverse brake).
Line pressure solenoid valve	Controls the line pressure control valve.
Lock-up solenoid valve	Controls the lock-up control valve.
Lock-up/Select switch solenoid valve	Controls the select switching valve.
Stepping motor	Controls the pulley ratio.
Secondary valve	Reduces the line pressure and adjusts the secondary pressure.
Select control valve	Engages when making a selection. Adjusts the forward clutch pressure and the reverse brake pressure.
Lock-up control valve	Adjusts engaging/releasing pressure for the torque converter.
Secondary pressure solenoid valve	Controls flow-in/out of line pressure to/from the secondary pulley depending on driving conditions.
