    Abstract: A transmission is provided having a housing, a plurality of planetary gear sets, a structural member, a sprocket member, a first dog clutch member, a second dog clutch member, and a biasing member. The structural member is secured to the housing and includes a plurality of splines and defines a cavity. The sprocket member is rotationally supported by the structural member. The first dog clutch member is disposed in the cavity of the structural member and includes splines and dogteeth. The splines are engaged with the splines of the structural member. The second dog clutch member includes dogteeth that are aligned with the dogteeth of the first dog clutch member. The biasing member is disposed between the structural member and the first dog clutch member.

    Abstract: A transmission is provided having a housing, a plurality of planetary gear sets, a structural member, a sprocket member, an annular drum, a band, and an actuator. The sprocket member is rotationally supported by the structural member. The annular drum is adjacent the structural member and is continuously rotationally coupled with a member of the one of the plurality of planetary gear sets. The band circumscribes the annular drum and includes at least a first position and a second position. In the first position the band is substantially separated from the drum and in the second position the band contacts the drum. The actuator selectively positions the band between at least the first position and the second position to transfer torque between the structural member and the annular drum.
