摘要： A manual valve is formed with a drain input port that closes if a shift is made to the D position, and opens for draining if a shift is made to the N position. A switching valve communicates an output port of a pressure regulating valve portion and an oil passage of a clutch and closes a drain port during engine operation when a line pressure is applied, and cuts off communication between the output port of the pressure regulating valve portion and the oil passage of the clutch and communicates the oil passage with the drain port during an engine automatic stop when the line pressure is not applied. The drain input port and the drain port are connected by a drain oil passage.
