LOCK-UP AND SELECT CONTROL SYSTEM
LOCK-UP AND SELECT CONTROL SYSTEM
System DiagramINFOID:0000000003806362
System DescriptionINFOID: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.

SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM
System DescriptionINFOID:0000000003806370
The shift lever it cannot be shifted from the “P” position unless the
brake pedal is depressed while the ignition switch is set to ON. The
shift lock is unlocked by turning the shift lock solenoid ON when the
ignition switch is set to ON, the park switch is turned ON (selector
lever is in “P” position), and the stop lamp switch is turned ON (brake
pedal is depressed) as shown in the operation chart in the figure.
Therefore, the shift lock solenoid receives no ON signal and the shift
lock remains locked if all of the above conditions are not fulfilled.
(However, selector operation is allowed if the shift lock release but-
ton is pressed.)
SHIFT LOCK OPERATION at “P” POSITION
When Brake Pedal Is Not Depressed (No Selector Operation Allowed)
The shift lock solenoid (A) is turned OFF (not energized) and the
solenoid rod (B) is extended with the spring when the brake pedal is
not depressed (no selector operation allowed) with the ignition
switch ON.
The connecting lock lever (C) is located at the position shown in the
figure when the solenoid rod is extended. It prevents the movement
of the detent rod (D). The selector lever cannot be shifted from the P
position for this reason.
When Brake Pedal Is Depressed (Shift Operation Allowed)
The shift lock solenoid (A) is turned ON (energized) when the brake
pedal is depressed with the ignition switch ON. The solenoid rod (B)
is compressed by the electromagnetic force. The connecting lock
lever (C) rotates when the solenoid rod is activated. Therefore, the
detent rod (D) can be moved. The selector lever can be shifted to
other positions for this reason.

The shift lock solenoid (A) is not energized when the ignition switch
is in any position other than ON. in this condition, the shift mecha-
nism is locked and “P” position is held. The operation cannot be per-
formed from “P” position if the brake pedal is depressed with the
ignition switch ON when the operation system of shift lock solenoid is
malfunctioning. However, the lock lever (B) is forcibly rotated and the
shift lock is released when the shift lock release button (C) is
pressed from above. Then the selector operation from “P” position
can be performed.
CAUTION:
Use the shift lock release button only when the selector lever cannot be operated even if the brake
pedal is depressed with the ignition switch ON.
