System Description

INFOID:0000000003806363

• The torque converter clutch piston in the torque converter is engaged to eliminate torque converter slip to

increase power transmission efficiency.

• The torque converter clutch control valve operation is controlled by the torque converter clutch solenoid

valve, which is controlled by a signal from TCM. The torque converter clutch control valve engages or
releases the torque converter clutch piston.

• When shifting between “N” (“P”) 

⇔

“D” (“R”), torque converter clutch solenoid valve controls engagement

power of forward clutch and reverse brake.

• The lock-up applied gear range was expanded by locking up the

torque converter at a lower vehicle speed than conventional CVT
models.

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 posi-

tion, the engine speed, and the secondary pulley (output) revolution speed to lessen the shift shock.
