A gear train of an auto transmission for the vehicles is provided to increase the capacity reduction and the oil pressure control efficiency of the oil pump by performing gear-change through the operation of the friction element of 2. The first planetary gear set(PG1) comprises the first, the second and the third rotation elements(N1,N2,N3). The first rotation element is operated as the stationary element. The second rotation element decelerates the rotation power inputted from the input shaft(IS) and forms the output. The third rotation element is directly connected to the input shaft. The third rotation element forms the second intermediate output route(MOP2). The second planet gear set(PG2) comprises the fourth, the fifth and the sixth rotation elements(N4,N5,N6). The fourth rotation element is connected to the second rotation element. The fifth rotation element is changeably connected to the third rotation element. The fifth rotation element is selectively operated as the stationary element. The sixth rotation element is operated as the output primitive.
