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