摘要： A planetary gear train of an automatic transmission is disclosed. The planetary gear train includes an input shaft receiving torque of an engine and an output shaft outputting torque. A first planetary gear set includes first, second, and third rotation elements, a second planetary gear set includes fourth, fifth, and sixth rotation elements, a third planetary gear set includes seventh, eighth, and ninth rotation elements, and a fourth planetary gear set including tenth, eleventh, and twelfth rotation elements. Each of a first plurality of shafts is fixedly connected with one of the rotation elements from the first, the second, the third, and the fourth planetary gear sets. A second plurality of shafts is formed by combinations of remaining rotation elements of the first, the second, and the fourth planetary gear sets that are not connected to the first plurality of shafts, and selectively and respectively connected to a transmission housing.
