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.
