SPLIT INPUT PLANETARY TRANSMISSION Abstract of the Disclosure A planetary transmission of a vehicle drive train comprises an input section including three planetary gear sets and three brakes that are selectively operable to condition the three gear sets for respectively establishing a forward converter drive, a reverse converter drive and a direct drive at an output shaft of the input section. The planetary transmission further comprises an output or range section coupled to the output of the input section. The output section includes three planetary gear sets connected together so as to form a three-stage planetary set and three brakes are respectively associated with the three gear sets and selectively operable to control the three gear sets such that low, intermediate and high output speeds are established for every input to the output section with drive torque being deliv- ered by all three gear sets for low speed operation, by two gear sets for intermediate speed operation and by a single gear set for high speed operation.
