Patent number: 7766786Abstract: 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 four planetary gear sets, five torque-transmitting devices, one grounded member and three fixed interconnections. The powertrain includes an engine and torque converter that is continuously connected to one of the planetary gear members and an output member that is continuously connected with another one of the planetary gear members. The five torque-transmitting devices provide interconnections between various gear members, and the transmission housing, and are operated in combinations of two to establish eight forward speed ratios and one reverse speed ratio.Type: GrantFiled: July 11, 2007Date of Patent: August 3, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Gregory Hukill, Scott H.
