The sun gear () of the first planetary gear set () is braked against the housing by engaging a first form-fit shift element (A). The sun gear () of the first planetary gear set () is coupleable to a carrier () of the first planetary gear set () via a second form-fit shift element (B) while providing a direct drive at the first planetary gear set ().
