ABSTRACT:
A hydraulic control system comprises first and second fluid operated friction units, the first fluid operated friction unit being discharged at the same time the second fluid operated friction unit is pressurized during a shift between two remote speed ratios. The hydraulic control system comprises a drain conduit having one end communicable with the first fluid operated friction unit and an opposite end, and a timing valve which discharges the drain conduit via an orifice when the fluid pressure supplied to the second fluid operated friction unit is lower than a predetermined value, while it discharges the drain conduit bypassing the orifice when the fluid pressure supplied to the second fluid operated friction unit exceeds the predetermined value.
