ABSTRACT:
A hydraulic circuit system in the automatic transmission has a hydraulic line or passage through which a hydraulic fluid delivered from a hydraulic power source or a hydraulic fluid output provided by a regulator valve is directly supplied to a torque converter, so that the overheat that may otherwise occur in the hydraulic fluid within the torque converter during the low engine output can effectively be prevented.
