摘要:
The transmission has a plurality of members that can be utilized in powertrains to provide eight forward speed ratios and one reverse speed ratio. The transmission includes three planetary gear sets having six torque-transmitting devices, two fixed interconnections and a grounded member. The powertrain includes an engine and torque converter that is selectively connected to at least one of the planetary gear members, and an output member that is continuously connected with another one of the planetary gear members. The six torque-transmitting devices provide interconnections between various gear members, the transmission housing and with the input member, and are operated in combinations to establish at least eight forward speed ratios and at least one reverse speed ratio.
