Abstract:
The family of transmissions has a plurality of members that can be utilized in powertrains to provide at least five forward speed ratios and one reverse speed ratio. The transmission family members include three planetary gear sets having up to seven torque-transmitting mechanisms and three interconnecting members. The powertrain includes an engine that is selectively or continuously connectable to at least one of the planetary gear members and an output shaft that is continuously connected with another one of the planetary gear members. The torque-transmitting mechanisms provide interconnections between various gear members, the input shaft and the transmission housing, and are operated in combinations of two to establish at least five forward speed ratios and at least one reverse speed ratio.
