Abstract: A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.
