Abstract

A transmission having a drive input shaft (AN), a drive output shaft (AB), a housing (G), at least two planetary gearsets (PR1, PR2), and at least three shifting elements (A, B, C) whose selective engagement produces various transmission ratios between the drive input shaft (AN) and the drive output shaft (AB), so that at least three gears can be obtained. To obtain a gear in each case, two shifting elements are engaged and a further shifting element is disengaged.
