The transmission of a work vehicle including a forward/reverse clutch for forward/backward switching and a shift clutch for driving shift comprises: a first axis on which the forward/reverse clutch is mounted; a second axis that rotates forward or reverse in conjunction with the first axis and is equipped with the shift clutch; a support member that is mounted within a housing and rotatably supports the first and second axes; a forward/reverse shift hydraulic valve device that is mounted on one side wall of the housing adjacent to the forward/reverse clutch and controls the forward/reverse clutch; and a shift hydraulic valve device that is mounted on the other side wall of the housing adjacent to the shift clutch and controls the shift clutch. The forward/reverse shift hydraulic valve device and the shift hydraulic valve device may be connected to the forward/reverse clutch and the shift clutch through passages formed in one support member. Accordingly, the forward/reverse shift hydraulic valve device and shift hydraulic valve device to effectively control each clutch can be designed with a simple and optimized structure.
