A clutch assembly comprises an input shaft and an output shaft, co-axially arranged relative to the input shaft. The clutch assembly further comprises an input clutch drum, fixed to the input shaft, and an output clutch drum, translatable relative to the output shaft. The clutch assembly further comprises a clutch pack and a clutch piston that is translatable relative to the output shaft between, inclusively, a frictionally disengaged clutch-pack position and a frictionally engaged clutch-pack position. The clutch assembly additionally comprises a clutch-pack engagement spring. The output clutch drum is translatable between, inclusively, a fully disengaged position and, inclusively, a positively engaged position. When the clutch piston is in the frictionally disengaged clutch-pack position, the internal splines of the output clutch drum are not in mesh with the external splines of the input clutch drum.

A shifting system includes an input member, a disconnect, an output member, and a shifting assembly to selectively rotationally couple the input member and the output member. The shifting assembly includes an input hub having a disconnectable component engageable with the disconnect and a clutch engagement component extending radially away from an axis. A plurality of clutch plates is coupled to the clutch engagement component and is moveable between engaged and disengaged positions. A biasing member is coupled to the clutch plates to bias the clutch plates toward the engaged position, and an apply plate is coupled to the biasing member. The apply plate is moveable between a first plate position where the clutch plates are in the engaged position, and a second plate position where the clutch plates are in the disengaged position. A clutch plate carrier is coupled to the clutch plates and to the output member.

A control device for a power transmission mechanism includes a controller. The power transmission mechanism includes an engagement mechanism and an operation mechanism including a movable member and a guide member. The guide member includes a plurality of guide areas being configured to move relative to the movable member to guide the movable member to an engaging position or to a disengaging position. The controller is configured to switch, when determining that a predetermined condition related to traveling of the vehicle is satisfied, a contact guide area that is in contact with the movable member to guide the movable member to the engaging position or to the disengaging position, from a first guide area to a second guide area that are included in the plurality of guide areas.
