摘要
A planetary gear transmission having a hydrokinetic torque converter, a compound planetary gear unit and a simple planetary gear unit, an output shaft for the planetary gear units disposed concentrically with respect to the converter, and five friction clutches and brakes for establishing three forward driving ratios and a reverse ratio, the high ratio being characterized by a solid mechanical drive, the two lower ratios being defined in part by the converter and the lowest ratio and the reverse ratio being characterized by a relatively high value in comparison to planetary three-speed ratio transmission mechanisms of known construction.
