TORQUE CONVERTER CLUTCH AND SELECT CONTROL VALVE CONTROL
Lock-up Released
In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the torque converter clutch solenoid valve and the lock-up apply pressure is drained.
In this way, the torque converter clutch piston is not coupled.
Lock-up Applied
In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the torque converter clutch solenoid valve and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
Select Control
When shifting between "N" ("P") <=> "D" ("R"), optimize the operating pressure on the basis of the throttle position, the engine speed, and the secondary pulley (output) revolution speed to lessen the shift shock.
Component Inspection (Torque Converter Clutch Solenoid Valve)
- CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE Check resistance between CVT unit connector terminal and ground. RESISTANCE SPECIFICATION CVT unit connector Ground Resistance (Approx.) Connector Terminal F24 12 3.0 - 9.0 ohms Is the inspection result normal? YES: INSPECTION END NO: Replace transaxle assembly. Refer to " «2WD : EXPLODED VIEW»(ref-295118-S21358052582008081400000) " (2WD), " «AWD : EXPLODED VIEW»(ref-295118-S16673714632008081400000) " (AWD).
