Abstract: In an automatic transmission disabling engine braking to act at a given shift stage in a D range selected by manually operating a selector lever, and enabling engine braking to act at the given shift stage in an L range, the transmission includes first and second meshing mechanisms, a one-way clutch, a first linkage for meshing the first meshing mechanism in synchronism with N-to-D movement, and a second linkage for meshing the second meshing mechanism in synchronism with D-to-L movement. Also provided is a rotating part configured to permit a driving force to be transmitted from an input member via the one-way clutch with the first meshing mechanism meshed in the D range and further configured to permit a driving force to be transmitted from the input member not via the one-way clutch with the first and second meshing mechanisms, each of which is meshed, in the L range.
