No Lock up

The torque converter clutch solenoid valve is turned OFF by the PCM. The lock up shift valve receives LC pressure (LA) on the left side, and modulator pressure (6) on the right side. The lock up shift valve is in the right side to uncover the port leading torque converter pressure (92) to the left side of the torque converter. Torque converter pressure (92) becomes torque converter pressure (94), and enters into the left side of the torque converter to disengage the torque converter clutch. The torque converter clutch is OFF.
