Abstract

PURPOSE: To surely perform the starting operation of an engine, by securely holding a switching valve for selecting a directly coupled clutch surely to a disengagement side of the directly coupled clutch when the engine is stopped, in an automatic speed change gear having a torque converter with the directly coupled clutch.
CONSTITUTION: An automatic speed change gear having a torque converter 1 with a directly coupled clutch 50 between an engine crank shaft 8 and turbine shaft 9 comprises an oil pressure source including an oil pump 101, speed selecting valve 210, shift valves 220 and 230 and a throttle valve 240. While a switching valve 60, for selecting communication of the oil pressure source with directly coupled clutch disengaging and engaging oil lines 87 and 89, and a lock-up control valve 70, for operating said valve 60, are provided. At this time, the switching valve 60 is provided with oil chambers 67 and 68 normally communicated with the oil lines 87 and 89, upper end oil chamber 66, to which line pressure is fed from an oil line 102, and lower end oil chamber 69, to which oil pressure is fed from an oil line 84, and constituted in such a manner as to press a spool 65 downward by a spring 61.
