The lock-up shift valve is in the right side, and uncovers the port leading torque converter pressure port (92) leading to the left side of the torque converter. Torque converter pressure (92) from regulator valve becomes torque converter pressure (94) at the lock-up shift valve, and enters into the left side of the torque converter to disengage the torque converter clutch. The torque converter clutch is OFF.
