ABSTRACT:
A hydraulic control system according to the present invention which features in providing an orifice fluidly disposed in a passage that allows fluid supply of hydraulic fluid pressure to a clutch in selecting a forward drive range from a neutral range and in shifting between speed ratios involving engagement of the clutch in the forward drive range, and an orifice control valve having means for providing a one-way flow bypass passage bypassing the orifice in selecting the forward drive range from the neutral range and selecting the neutral range from the forward drive range, and providing a restricted flow bypass passage bypassing the orifice in shifting between speed ratios involving engagement of the clutch. The one-way flow bypass passage prevents fluid flow therethrough toward the clutch.
