Lock-up System (cont'd)

No Lock-up

The torque converter clutch solenoid valve is turned OFF by the PCM. The lock-up shift valve receives modulator (LC A) pressure (6C) on the left side and stays in the right side to uncover the port leading torque converter pressure (94) to the left side of the torque converter. Torque converter pressure (94) enters into the left side of the torque converter to disengage the lock-up clutch. The lock-up clutch piston keeps away from the torque converter cover; the lock-up clutch is OFF.

NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
