Abstract: An electric vehicle transmission includes a housing, a first gear, a second gear, and a first clutch pack supported in the housing. A first actuator is arranged in the housing. The first actuator is coupled with a first actuator member. A second actuator is arranged in the housing. The second actuator is coupled with a second actuator member. A modular actuation system is mounted to the housing. The modular actuation system includes a first energizer member and a second energizer member. The first energizer member is operatively connected to the first actuator and is operable to engage the first gear and the second energizer member is operatively connected to the second actuator and is operable to engage the second gear.

Abstract: A torque converter for a vehicle includes an annular housing. A turbine member is fluidically connected to the pump member. A lock-up clutch is selectively engaged between the annular housing and the turbine member. A lock-up clutch actuator is connected to the lock-up clutch. A cavity is defined between the annular housing and the turbine member. A first fluid circuit is fluidically connected to the pump member, the cavity and a first side of the lockup clutch actuator. The first fluid circuit delivers a fluid to engage the lock-up clutch actuator. A second fluid circuit is hydraulically connected to the pump member and the cavity. The second fluid circuit guide the fluid from the annular housing. A third fluid circuit is hydraulically connected to a second side of the lock-up clutch actuator. The third fluid circuit selectively delivers a pressurized fluid to release the lock-up clutch.

Abstract: A hybrid powertrain includes an internal combustion engine and a multi-speed transmission coupled to the internal combustion engine. The multi-speed transmission includes an input member, an output member, and a first, second, third, fourth, and fifth planetary gear set each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes a first, second, third, fourth, and fifth planetary gear sets each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes seven torque-transmitting devices configured to selectively interconnect the first, second, third, fourth, and fifth planetary gear sets with one another in combinations of at least four to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.

Abstract: A three mode continuously variable transmission (CVT) for a motor vehicle includes an optional speed change device connected to a pulley and a belt assembly or other continuously variable unit. The pulley and belt assembly is also connected to a planetary gear set arrangement. The planetary gear set arrangement generally includes two planetary gear sets, two brakes and two clutches. The planetary gear set arrangement is connected to a final drive unit. Engagement of the clutches and brakes provides three modes of operation to the CVT.
