Claims

[Scope of utility model registration request]

A transmission actuating device that performs a gear shifting operation of a transmission, which includes a select cylinder device that has a select piston that limits a first select pressure chamber and a second select pressure chamber, and that performs a select operation of the transmission; A shift cylinder device that has a shift piston that limits a second shift pressure chamber and performs a shift operation of the transmission, a hydraulic pressure supply source that supplies hydraulic pressure to each of the pressure chambers, the hydraulic pressure supply source and the first select A first select solenoid valve disposed in a first select pressure passage that communicates with the pressure chamber; and a second select solenoid valve disposed in a second select pressure passage that communicates the hydraulic pressure supply source with the second select pressure chamber. a first shift solenoid valve disposed in a first shift pressure passage that communicates between the hydraulic pressure supply source and the first shift pressure chamber; a second shift solenoid valve that communicates between the hydraulic pressure supply source and the second shift pressure chamber; A second shift solenoid valve disposed in the shift pressure passage, a centralized control device that supplies current □ from the power source to each of the solenoid valves to select and operate the gear stage of the transmission, and is independent of the central control device. and a control circuit configured to control the supply of current to each of the solenoid valves, the control circuit being
In the second stage, both the first and second shift solenoid valves are operated to select a shift neutral position, in the second stage, the first or second select solenoid valve is further operated to select a predetermined select position, and in the third stage A transmission operating device further comprising a manually operated switch for operating one of the first or second shift solenoid valve to select a predetermined shift position.
