ABSTRACT:
A lock-up type automatic transmission system includes a torque converter having a lock-up control valve and a lock-up solenoid for controlling the lock-up control valve. In the lock-up state, the lock-up control valve supplies a torque converter operating pressure to an apply chamber of the torque converter and it connects a release chamber of the torque converter to a drain circuit. In the converter state, the lock-up control valve supplies the operating pressure to the release chamber and connects the apply chamber to the drain circuit. In the lock-up state, when the apply pressure to the apply chamber reaches or exceeds a predetermined level, the lock-up control valve operates as a by-pass valve and directs excess hydraulic fluid, which is directed to the apply chamber, to the drain circuit or an oil cooler interposed in the drain circuit.
