Fluid in the chamber between the torque converter cover and the torque converter clutch piston is drained off, and
fluid entering from the chamber between the pump and stator exerts pressure through the torque converter clutch
piston against the torque converter cover. The torque converter clutch piston engages with the torque converter cover;
torque converter clutch lock-up ON, and the mainshaft rotates at the same as the engine.
Fluid entered from the chamber between the torque converter cover and the torque converter clutch piston passes
through the torque converter and goes out through the chambers between the turbine and the stator, and between the
pump and the stator. As a result, the torque converter clutch piston moves away from the torque converter cover, and
the torque converter clutch lock-up is released; torque converter clutch lock-up OFF.

The torque converter clutch solenoid valve is turned OFF by the PCM. The lock-up shift valve receives LC pressure (LA)
on the left side, and modulator pressure (6) on the right side. The lock-up shift valve is in the right side to uncover the
port leading torque converter pressure (92) to the left side of the torque converter. Torque converter pressure (92)
becomes torque converter pressure (94), and enters into the left side of the torque converter to disengage the torque
converter clutch. The torque converter clutch is OFF.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

As the speed of the vehicle reaches the prescribed value, the torque converter clutch solenoid valve is turned ON by
the PCM to release LC pressure (LA) in the left cavity of the lock-up shift valve. Modulator pressure (6) is applied to the
right side of the lock-up shift valve, then the lock-up shift valve is moved in the left side to switch the port leading
torque converter pressure to the right side of the torque converter. Torque converter pressure (91) is applied to the
right side of the torque converter to engage the torque converter clutch. The PCM also controls A/T clutch pressure
control solenoid valve C, and LS C pressure (58) is applied to the lock-up control valve and the lock-up timing valve.
When LS C pressure (58) is lower, torque converter pressure (91) from the lock-up timing valve is lower. The torque
converter clutch is engaged partially. LS C pressure (58) increases, and the lock-up timing valve is moved to the left
side to uncover the port leading torque converter pressure to high. The torque converter clutch is then engaged
securely. Under this condition, the torque converter clutch is engaged by pressure from the right side of the torque
converter; this lock-up condition is partial lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

When the vehicle speed further increases, the PCM controls A/T clutch pressure control solenoid valve C to increase
LS C pressure (58). The LS C pressure (58) is applied to the lock-up control valve and the lock-up timing valve, and
moves them to the left side. Under this condition, torque converter back pressure (F2) is released fully, causing the
torque converter clutch to be fully engaged.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
