Lock-up System (cont'd)

Full Lock-up

When the vehicle speed further increases, the PCM controls the A/T clutch pressure control solenoid valve B to increase linear solenoid B pressure (6E). Linear solenoid B pressure (6E) is applied to the lock-up control valve and the lock-up timing valve and moves them to the left side. Torque converter pressure (94) from the left side of the torque converter is drained at the lock-up control valve and torque converter pressure (91) engages the lock-up clutch securely.

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