PROBLEM TO BE SOLVED: To provide a hydraulic control system for an automatic transmission and a control system for the automatic transmission capable of achieving a reverse stage even if a valve that achieves a reverse inhibiting function fails.SOLUTION: In a switching valve 26, reverse range pressure is inputted into a plurality of input ports 26c, 26g and control pressure from a linear solenoid valve SL3 can be inputted into an input port 26e. The switching valve 26 has an output port 26f connected to a hydraulic servo 33 of a clutch C-3, an output port 26b connected to an input port 27e of B2 apply control valve, and an output port 26d connected to an input port 27c of the B2 apply control valve. The reverse range pressure can be outputted to the output port 26b. The reverse range pressure or the control pressure can be outputted to the output ports 26d and 26f. The input ports 27c, 27e are selectively connected to a hydraulic servo 35. |
