Abstract

PURPOSE:To prevent the generation of abnormal noise by installing an engaging means which engages a servovalve at a retreat position. CONSTITUTION:When a manual valve 9 is selection-operated from R range to N or R range, a servovalve 11 is held at a retreat position by an engaging means, and the selection from the retreat side to the advance side of a selector gear 6 is not carried out. Therefore, generation of abnormal noise is suppressed. Further, when the manual valve 9 is selection-operated to the advance range, the servovalve 11 is pushed to the advance position by the hydraulic pressure against the engagement force of the engaging means 22, and a prescribed transmission system (four speed transmission system) which commonly uses a hydraulic clutch C4 together with a retreat transmission system can be surely established by feeding oil into the hydraulic clutch C4, and no trouble is generated in the function.
