    摘要: A starting valve has a start fluid pressure regulating state and a complete engagement fluid pressure regulating state and supplies a regulated fluid pressure to a hydraulic clutch. A shift operating mechanism comprises a rod movable within a reduction ratio select range and an overstroke range. A complete engagement control valve has a spool operatively connected with the rod. When the rod is disposed within the reduction ratio select range, the complete engagement control valve renders the starting valve operable in the complete engagement fluid pressure regulating state, while when the rod is disposed within the overstroke range, the complete engagement control valve renders the starting valve operable in the start fluid pressure regulating state.
