An architecture for coupling the output of a prime mover to a rotationally driven device. The architecture includes a selectable switching device, a terminal output member and a torque transfer device having an intermediate output member. The selectable switching device is coupled to the output of the prime mover and is selectively and alternately coupled between first and second states; in the first state with the torque transfer device, whereby the torque transfer device is rotatably driven by the prime mover and the terminal output member is rotatably driven by the intermediate output member of the torque transfer device; and in the second state with the terminal output member, whereby the terminal output member is rotatably driven by the prime mover and the torque transfer device is rotatably disconnected from the prime mover and is not rotatably driven.

A method of operating a shifting system for a vehicle transmission includes engaging a clutch to operatively couple one of first and second gear ratios to an input member, and moving a disconnect from a first disconnect position where a disconnectable component is disengaged from the disconnect, to a second disconnect position where the disconnectable component is engaged with the disconnect to operatively couple the other of the first and second gear ratios to the input member through a shifting assembly. Engaging the clutch and moving the disconnect are performed such that the clutch is operatively coupled to one of the first and second gear ratios at the same time that the shifting assembly is operatively coupled to the other one of the first and second gear ratios, thus preventing torque from being transmitted through either the first and second gear ratios of the vehicle transmission to park the vehicle.

A driveshaft of the main group is connectable by a first powershift clutch to a first input shaft and is connectable by a second powershift clutch to a second input shaft of the main group. Spur gear stages of the main group can be integrated into the force transfer path by actuating an associated shift element, coupling an associated input shaft to the drive shaft of the main group by configuring a respective gear of the main group.
