Abstract
A powertrain has a prime mover and a final drive gearing interconnected by a planetary gear arrangement including three planetary gear sets and five torque transmitting mechanisms. The planetary gear sets each have three rotatable members. Two members of a first of the planetary gear sets are continuously interconnected respectively with members of a second of the planetary gear sets. One of the interconnected pairs is continuously connected with the prime mover. The third member of the second planetary gear set is continuously connected with one member of the third of the planetary gear sets. Another member of the third planetary gear set is continuously connected with the final drive gearing. Three of the torque transmitting mechanisms are operatively connected between the planetary gear sets and a transmission housing to selectively restrain rotation of selected members of the three planetary gear sets. The fourth of the torque transmitting mechanisms is an interconnecting mechanism that connects at least the prime mover and one member of the first planetary gear set with an otherwise unconnected member of the third planetary gear set. The fifth torque transmitting mechanism is …
