Abstract
PURPOSE: To prevent an engine stall when an automobile stops due to an error or fault of valves such as solenoid valve and electric circuit, by connecting a lock-up shift valve with a hydraulic servo which is fed with hydraulic pressure except for the first gear.
CONSTITUTION: A hydraulic controller of this automatic transmission gear, including a controller of a clutch 50 connected with a torque converter, is equipped with a selective valve 210 connected with an oil pump 101 through a pressure regulating valve 200, 1-2 shift valve 220, 2-3 shift valve 230, throttle valve 240, lock-up shift valve 300, governor control valve 310, etc. An oil line 140 connecting the lock-up shift valve 300 with a hydraulic servo is equipped with a solenoid valve 390. The valve 300 lowers a spool 301 by means of a spring 302, irrespective of the action of solenoid valve 390, for the first gear and releases the clutch 50 through connection with oil lines 103, 130.
