Abstract
A vehicle transmission realizes speed change via variation in rotation speed and direction by selective control operation using combinations of six friction elements and a plurality of rotating elements of four planetary gear devices, and enables vehicle driving by realizing at least ten stage gear ratios for forward movement and at least one stage gear ratio for backward movement based on different speeds, wherein the vehicle transmission may increase fuel efficiency and power performance resulting from the multiple stages of the transmission.
