Abstract
A simple planetary gearset, a compound pinion planetary gearset, two clutches and two brakes are combined to provide four forward speed ratios and a reverse ratio. One of the clutches provides an input connection while the other provides a planetary interconnection. The two brakes are connected with respective first and second members of the simple planetary gearset while the third member of the planetary is continuously driven by a power input. The compound pinion planetary gearset has one member continuously connected with a power output shaft, a second member connected with the input clutch and the interconnecting clutch, and a third member connected with one of the brakable members of the simple planetary gearset.
