Torque Converter Clutch Lock-up OFF (Disengaging Torque Converter Clutch)

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 lock-up clutch is released; torque converter clutch lock-up is OFF.

No Lock-up

Shift solenoid valve E is turned OFF by the PCM, and shift solenoid valve E pressure (SE) is not applied to the
lock-up shift valve. The lock-up shift valve stays to the right to uncover the torque converter pressure ports
leading to the left: side of the torque converter and releasing pressure from the right side of the torque converter.
Torque converter pressure (92) changes to (94) at the lock-up shift valve, and enters into the left side of the
torque converter to disengage the torque converter clutch. This keeps the torque converter clutch piston keeps
away from the torque converter cover and the torque converter clutch lock-up is OFF.

Partial Lock-up

As the speed of the vehicle reaches the programmed value, shift solenoid valve E is turned ON by the PCM, and
shift solenoid valve E pressure (SE) is applied to the right side of the lock-up shift valve. The lock-up shift
valve is moved to the left side to switch the torque converter pressure (91) port, which goes to the right side of
the torque converter, and the port of torque converter pressure (94) is released from the left side of the torque
converter. Torque converter pressure (91) flows 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 A, and A/T clutch pressure
control solenoid valve A pressure (55) is applied to the lock-up shift valve and lock-up control valve. The
position of the lock-up control valve depends on A/T clutch pressure control solenoid valve A pressure (55) and
torque converter pressure released from the torque converter. The lock-up control valve controls the amount of
torque converter clutch lock-up until fluid between the clutch piston and torque converter cover is fully
released; the torque converter clutch is in partial lock-up.

Full Lock-up

When the vehicle speed increases, the PCM sends a signal to A/T clutch pressure control solenoid valve A to
increase A/T clutch pressure control solenoid valve A pressure (55), and the lock-up control valve is moved to
the left side by increased pressure. Then converter pressure (94) from the left side of the torque converter is
completely released at the lock-up control valve, and torque converter pressure (91) engages the torque
converter clutch securely; the torque converter clutch is in full lock-up.

When used, "left" or "right" indicates direction on the hydraulic circuit.
