Beschreibung
Zusammenfassung:	A hydraulically actuated transmission includes a selecting switching valve configured to selectively switch between a first switching valve and a second switching valve as a valve to be connected with an outlet port of a solenoid valve. The selecting switching valve is configured to operate in response to a hydraulic pressure applied to a specific frictional coupling element (second brake) in accordance with coupling and releasing of the specific frictional coupling element, and is configured to connect the outlet port with the first switching valve while the hydraulically actuated transmission is in high gear which is higher than or equal to a predetermined gear, and connect the outlet port with the second switching valve while the hydraulically actuated transmission is in the low gear which is lower than the predetermined gear.
