Abstract

The invention concerns an automatic transmission of planetary structure, comprising a drive input shaft (AN), a drive output shaft (AB), first, second, third and fourth planetary gear sets (RS1, RS2, RS3, RS4) and six shifting element (A, B, C, D, E, F). By the selective engagement of three of a total of six shifting elements (A to F), ten forward gears and up to two reverse gears can be engaged without range shifts.
