Abstract
A compact structure for a speed change mechanism within a transmission is shown. An automatic transmission includes an input shaft supported at its opposite ends, an input member operatively connected to a first end of the input shaft, an output member mounted on a second end of the input shaft, and a speed change mechanism disposed between the input member and the output member, and including planetary gear trains supported on the input shaft. The portion of the input shaft supporting the planetary gear trains need not transmit torque, thus allowing the use of a reduced diameter input shaft.
