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.
