摘要： A hydraulic control system of an automatic transmission may be applied to an automatic transmission in which a reverse speed stage is engaged by engagement of first and second friction elements. The hydraulic control system may include: a first solenoid valve being a normally open type and controlling a line pressure to generate a first hydraulic pressure; a second solenoid valve being a normally closed type and controlling the line pressure to generate a second hydraulic pressure; first and second switch valves, the first switch valve selectively supplying the first hydraulic pressure to the second switch valve; and a fail-safe valve selectively supplying the first hydraulic pressure or the second hydraulic pressure to the second friction element, wherein the second switch valve selectively supplies the first hydraulic pressure supplied from the first switch valve or a reverse speed pressure to the first friction element.
