Abstract
A multiple-speed transmission provides a wide gear ratio coverage for an automotive vehicle by using a basic structure of a six-speed transmission. The multiple-speed transmission is comprised of a combination of two planetary gearsets, three clutches, and three brakes. Each speed is established by applying two of six elements of the three clutches and the three brakes.
