Abstract: A torque transmitting mechanism for a transmission includes a first and a second rotating member, a rotating piston, a stationary piston, and a first bearing. The rotating piston is rotatably connected to the first rotating member and includes a splined end. The stationary piston is disposed in a stationary housing of the transmission. The stationary piston and the stationary housing form a hydraulic fluid piston apply chamber. The first bearing is disposed between the rotating piston and the stationary piston. The splined end of the second rotating member is axially aligned and configured to engage with the splined end of the rotating piston.

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.

Abstract: A transmission includes a first planetary gearset and a second planetary gearset, each having a respective first planetary member, a respective second planetary member, and a respective third planetary member. The planetary members of the first planetary gearset are coaxially disposed on, and selectively rotatable about, a first axis. The planetary members of the second planetary gearset are coaxially disposed on, and selectively rotatable about, a second axis. An axis transfer mechanism including meshing gears transmits torque between the first and second planetary gearsets.
