Abstract: To disable engine braking so as to act at a given shift stage in a D range selected manually, and to enable engine braking so as to act at the given shift stage in an L range, an automatic transmission includes first and second meshing mechanisms. The transmission further includes 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. A rotating part permits 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 permits a driving force to be transmitted from the input member, without transmitting via the one-way clutch, with the first and second meshing mechanisms each meshed in the L range.

Abstract: A first element of a duplex planetary gear set is selectively coupled to an input shaft via a third clutch, or is selectively fixed via a first brake. A second element is selectively coupled, via a second clutch, to an intermediate shaft that is directly coupled to a speed-increasing element of a simplex planetary gear set which increases the rotational speed of the input shaft, or is selectively fixed via a second brake. A third element is directly coupled to an output shaft. A fourth element is selectively coupled to the input shaft via a first clutch. Therefore, by increasing the speed of the rotation of the input shaft by the simplex planetary gear set and transferring it to the duplex planetary gear set, it is possible to reduce the torques on individual components of an automatic transmission and therefore to reduce the sizes of the individual components and the capacities of the individual friction engagement elements.

Abstract: A planetary gear unit PR and a clutch C3 for outputting reduced speed rotation and a clutch C1 for connecting and disconnecting input of rotation of an input shaft to a sun gear S2 are located on one axial side of a planetary gear unit PU, and a clutch C2 for connecting and disconnecting input of rotation of the input shaft to the carrier CR2 is located on the axially opposite of the planetary gear unit PU. By doing so, as compared to a case wherein, for example, a clutch C1 and clutch C2 are both located between a pair of planetary gear units PR and PU, the planetary gear units PR and PU can be located more closely together, and the member that transmits the reduced speed rotation from planetary gear unit PR to planetary gear unit PU can be made shorter. Further, compared to the case wherein, for example, the clutches C1, C2, C3 are located on one axial side of the planetary gear units, the construction of the oil lines is simplified.
