    • PURPOSE:To plan to improve the fuel consumption of an engine by operating the direct connection clutch upon running at a comparatively low vehicle speed and at a high speed under a high throttle including the full throttle by a method wherein a governor pressure and a hydraulic pressure in a throttle kickdown circuit are introduced into a lock-up control valve. CONSTITUTION:The lock-up control valve 34 is provided with a pair of spools 66, 67, a spring 68 arranged between the opposing spools, an engaging chamber 69 equipped above it and a non-engaging chamber 70 equipped below it. The engaging chamber 69 is connected to a governor pressure oil passage 51 while the non-engaging chamber 70 is connected to a throttle kickdown pressure oil passage 52, and pressurized oil from the oil passage 54 is introduced into an inlet port 64 through a 2-3 shift valve 32. When the pressure of the governor is increased and the spool 67 is descended against the energizing force of the spring 68 and the oil pressure in the throttle kickdown pressure oil passage 52, the inlet port 64 is connected to a pressure oil passage 71 for the direct connection clutch and the direct connection clutch 25 is closed.
