An automatic transmission includes first shaft, second shaft, four planetary gear sets, and six shift elements for forming different gear ratios between the first and second shafts. The first, third and fourth planetary gear sets are negative planetary gear sets and the second planetary gear set is a positive planetary gear set. The planetary gear carriers of the first, second, and fourth planetary gear sets are connected and form the first shaft. The planetary gear carrier of the third planetary gear set forms the second shaft. First shift element is between a third shaft and the housing; second shift element is between a fourth shaft and the housing; third shift element is between second and eighth rotatable shafts; fourth shift element is between fourth and sixth rotatable shafts; fifth shift element is between fifth and seventh rotatable shafts; and sixth shift element is between sixth and the seventh rotatable shafts.
