摘要： A planetary gear train of an automatic transmission for vehicles provides forward ten speed stages and one reverse speed stage. The planetary gear train includes: an input shaft; an output shaft; five planetary gear sets each having three rotation elements; three clutches; three brakes; and nine shafts. Some of the nine shafts may directly connect or selectively connect a plurality of rotation elements among the rotation elements via the clutches, and some of the nine shafts selectively connect selected rotation elements to a transmission housing H via the brakes. In particular, the selected rotation elements are not connected to another rotation element of the five planetary gear sets.
