Abstract
A multi-stage auto transmission for a vehicle may include first, second, third and fourth planetary gear sets each including first, second and third rotating elements, friction members including first, second and third clutches and first, second and third brakes, an input shaft to which rotation power is inputted, and an output shaft from which the rotation power is outputted. By selectively or continuously connecting the rotating elements of the planetary gear sets to the input shaft, the output shaft or each other, the multi-stage auto transmission implements ten forward speeds and one reverse speed.
