## Abstract

A shifting assembly for a transmission at least has a first component, a second component, and a third component, the components interacting according to the shift state in that a friction clutch is arranged between the first component and the second component, a positively-locking clutch is arranged between the second component and the third component, and a freewheel unit is arranged between the second component and the third component. A connection means is provided which connects a clutch part of the friction clutch to a clutch part of the positively-locking clutch.
