A transmission includes input (28) and output (200) shafts, a hybrid module (12) coupled to the input shaft (28) and a gearbox (16) coupled to the hybrid module (12) and output shaft (200). The hybridmodule (12) includes a first electric motor (40) underdriven by a gearset (36); a second electric motor (48) coupled to a module output (56), a disconnect clutch (32) coupled to the gearset (36) andselectively to the input shaft (28); and a launch clutch (44) coupled to the disconnect clutch (32) and selectively to the module output (56). The gearbox (16) includes three gearsets (148, 152, 156)and five torque transmitting devices (122, 128, 132, 136, 140) operable to generate six forward speeds. One torque transmitting device is a selectively controllable one-way clutch (136). 变速器包括输入轴(28)和输出轴(200)、连接至输入轴(28)的混合动力模块(12)以及连接至混合动力模块(12)和输出轴(200)的变速箱(16)。混合动力模块(12)包括由齿轮组(36)下部驱动的第一电动机(40)；连接到模块输出(56)的第二电动机(48)；连接到齿轮组(36)并且选择性地连接到输入轴(28)的分离离合器(32)；连接至分离离合器(32)并选择性地连接至模块输出(56)的启动离合器(44)。变速箱(16)包括可操作以产生六个前进速度的三个齿轮组(148
