    Abstract: A two-speed transmission for a vehicle is provided including a planetary gear set selectively coupling an input shaft and an output shaft. The planetary gear set is configured to provide two forward gear ratios and neutral. The planetary gear set includes at least one sun gear, at least one pinion in meshing engagement with the sun gear, at least one ring gear meshingly engaged with the pinion, and a carrier. The carrier supports the pinion and is connected to the output shaft such that rotation of the carrier drives the output shaft. The two-speed transmission also includes one or more elements that rotatably couple different combinations of the sun gear, the pinion, the ring gear, the input shaft, and the carrier with one another or a ground. Such elements may include combinations of clutches, brakes, and dog clutches.

    Abstract: A torque converter for coupling an engine to a manual transmission and a method of controlling the same are provided. The torque converter includes a housing rotating with the engine, a cover abutting the housing, a stator, a pump circulating fluid within the torque converter, and a turbine driven by the circulating fluid. An integrated disconnect clutch controls pump speed and a torsional damper attenuates vibrations transmitted through the housing. A first output shaft is coupled with the turbine and drives a first forward gear of the manual transmission while permitting slip. A second output shaft is coupled with the torsional damper, the integrated disconnect clutch, and the pump and drives at least one other forward gear of the manual transmission without slip. An output connection member rotatably couples the pump with the torsional damper, the integrated disconnect clutch, and the second output shaft.

    Abstract translation: 提供了一种用于将发动机耦合到手动变速器的变矩器及其控制方法。 变矩器包括与发动机旋转的壳体，邻接壳体的盖，定子，变矩器内的泵循环流体和由循环流体驱动的涡轮。 集成的断开离合器控制泵速度和扭转阻尼器减弱通过壳体传递的振动。 第一输出轴与涡轮机联接并驱动手动变速器的第一前进档，同时允许滑动。 第二输出轴与扭转阻尼器，集成断开离合器和泵耦合，并且驱动手动变速器的至少一个其它前进挡，而不会滑动。 输出连接构件将泵与扭转阻尼器，集成断开离合器和第二输出轴可转动地连接。
