VEHICLE TRANSMISSION

PROBLEM TO BE SOLVED: To provide a vehicle transmission having shift stages for eleven forward speed ranges and a single reverse speed range in a comparatively simple structure by a small number of components.SOLUTION: A vehicle transmission characteristically includes a first composite planetary gear device CG1 in which a first planetary gear device PG1 and a second planetary gear device PG2 are connected, a second composite planetary gear device CG2 in which a third planetary gear device PG3 and a fourth planetary gear device PG4 are connected and at least one or more rotary elements are connected to a rotary element of the first composite planetary gear device CG1, an input shaft and an output shaft which are connected to at least one rotary element of the first planetary gear device CG1 and are selectively connected to another rotary element of the first composite planetary gear device CG1 and a rotary element of the second composite planetary gear device CG2, a first brake B1 and a second brake B2, a third brake B3 for fixing the rotary element of the second composite planetary gear device CG2, and a first clutch CL1 for selectively connecting between the first planetary gear device PG1 and the rotary element of the second planetary gear device PG2.
