Manual Description
Stop lamp switch Releases lock-up system when depressing pedal in lock-up condition. Clutch operating pressure (line pressure) must be increased to deal with this driving force. This pressure rise is adopted to prevent a delay in clutch and brake operation due to extreme drop of fluid viscosity at low temperature.

This is accomplished by electrical signals transmitted by the revolution sensor and throttle position sensor. The pilot pressure pushes the end face of the torque converter clutch control valve in combination with spring force to move the valve to the left. As a result, converter pressure is applied to chamber A (torque converter clutch piston release side).

Accordingly, the control valve moves to the right by the pilot pressure of the other circuit and converter pressure. Also smooth lock-up is provided by transient application and release of the lock-up. However, drive force from the wheels is not transmitted to the engine because the one-way clutch rotates idle.
