Abstract

The family of transmissions has a plurality of members that can be utilized in powertrains to provide at least seven forward speed ratios and one reverse speed ratio. The transmission family members include three planetary gear sets having six torque-transmitting mechanisms. The powertrain includes an engine and torque converter that is continuously connected to at least one member of the planetary gear arrangement and an output member that is continuously connected with another of the planetary gear members. One planetary gear member is continuously connected with the transmission housing. The six torque-transmitting mechanisms provide interconnections between various gear members and with the transmission housing, and are operated in combinations of four to establish at least seven forward speed ratios and one reverse speed ratio.
