Abstract:
A hydraulic control device that includes a second switching valve that is switchable between a third position in which the forward range pressure input from the first switching valve is output to the shift controller and the reverse range pressure is blocked when the second signal pressure is off and a fourth position in which the reverse range pressure input from the first switching valve is output to the shift controller and the forward range pressure is blocked when the second signal pressure is on.
