Abstract

A power-shiftable transmission, in particular an automatic transmission for a vehicle, which comprises a plurality of frictional shifting elements and at least one interlocking shifting element (A, B, C, D, E) and a plurality of gearwheels which can be engaged in a power flow by the shifting elements (A, B, C, D, E). In order to engage a gear step, at least two associated shifting elements (A, B, C, D, E) are engaged and at least one interlocking shifting element (B), as a shifting element (B) to be engaged, is associated with a gear step to be engaged with a supporting gear.
