Abstract
A transmission for a vehicle includes first, second, third and fourth planetary gear set, and a plurality of friction members. Each planetary gear set includes three rotating elements. The friction elements selectively and operably connect the rotating elements of the planetary gear sets to control rotation of the rotating elements. The transmission improves fuel efficiency by increasing the number of gears and enhances driving stability of the vehicle using an operating point in a low RPM range of the engine.
