ABSTRACT:
A control mechanism of a power shift transmission is disclosed and arranged in oil passages between the hydraulic pressure source and a hydraulic clutch, comprising an inching valve disposed in an upstream passage of said passages; a selector valve disposed in a downstream passage of said passages; a sequence valve of which an operation chamber is connected to a portion between the selector valve and the hydraulic clutch; and a modulator valve having a modulation chamber connected to a portion between the pressure source and the selector valve. The sequence valve is provided with a spool operable to move in accordance with a pressure in the operation chamber and to alternatively connect a booster chamber in the modulator valve to the inching valve and an upstream portion to the inching valve, so that a hydraulic pressure is always supplied into the booster chamber while the selector valve introduces the pressure into the clutch and the inching valve is operated.
