Abstract
A range switching device for performing switching the range of a transmission includes first control valve, a second control valve having a characteristic opposite to the first control, and first, second, third and fourth switching valves for controlling the transmission of oil pressures. The first and second switching valves cooperatively control the transmission of the oil pressure from the first control valve to a forward or reverse driving element (R). The third and fourth switching valve cooperatively control the transmission of the oil pressure from the second control valve to the forward or reverse driving element (R). The third and fourth switching valves each perform a substantially same oil pressure transmission when the state of the second and third actuators is reversed with respect to the first switching and second switching valves, respectively.
