摘要：
A hydraulic controller for transmission includes a brake and a clutch each of which corresponds to a different transmission ratio. An orifice control is provided in the conduit structure of the hydraulic circuit for actuating the clutch and brake such that a working oil quantity is varied in response to the engine throttle valve opening.
