Abstract
A vehicle transmission includes: four planetary gear sets and six friction elements which may be combined such that the rotation speed and direction are changed by selectively interrupting operations using the rotation elements of the planetary gear sets and the plurality of friction elements, wherein with such a shifting action, the vehicle may be driven by implementing gear ratios of at least ten forward stages and at least one reverse stage.
