Abstract
A hydraulic control device that includes a second solenoid valve that is capable of supplying a resisting pressure that maintains the switching valve in the non-reverse state against the reverse range pressure, wherein the switching valve is maintained in the non-reverse state by supplying the resisting pressure from the second solenoid valve while a travel range is switched to at least a reverse range during forward travel.
