Abstract

PURPOSE:To prevent the generation of abnormal noise and friction by restraining a servovalve to a retreat position until the hydraulic pressure of a hydraulic clutch in the second transmission system among the transmission systems for advance in which the oil feed is started from the timepoint of switching operation of a manual valve to an advance range becomes a prescribed value or more. CONSTITUTION:When a manual valve 9 is selection-operated from R range to advance range, a control valve 22 is held at a restriction position until the first speed pressure becomes a prescribed pressure, and a servovalve 11 is switched to an advance position. Therefore, when the manual valve 9 is switched from R range to advance range by stepping ON a brake, the revolution of an input shaft is restrained by the engagement force of the first speed hydraulic clutch C1, at the time point when the servovalve 11 is switched to the advance position, and even if the servovalve 11 is set into an N-range, the input shaft does not revolve, and a selector gear 6 and a counter gear G4a are smoothly meshed, in revolution state, and generation of abnormal noise is prevented.
