Abstract

A transmission includes a drive shaft, an output shaft, three planetary gear sets, and five shift elements, the first and second planetary gear sets are negative or minus gear sets. The third planetary gear set comprises three elements. The drive shaft is connected to the first element. A ring gear of the first planetary gear set is connected to the second element. The drive shaft is connectable to a sun gear of the first planetary gear set through the first shift element. The third element is rotationally fixable through the second shift element. The sun gear of the second planetary gear set is rotationally fixable through the third shift element. The planetary carrier of the second planetary gear set is rotationally fixable through the fourth shift element. The drive shaft is connectable to the planetary carrier of the second planetary gear set through the fifth shift element.
