摘要:
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.
