Abstract: A motor vehicle powertrain includes an engine, a motor/generator including a rotor, gearing including an input driveably connected to the engine, and an output secured to the rotor and driven in a rotary direction opposite to that of the input.

Abstract: An apparatus for supporting an electric power source in a transmission includes a transmission housing, and an electric machine including a rotor and a stator secured to the housing. A first member is secured to the rotor, extends radially toward an axis of rotation, and is formed with a first pilot surface. A second member, secured to the rotor and the housing, extends from the housing toward the axis and is formed with a second pilot surface that is aligned axially with the first pilot surface. An anti-friction bearing, located at an axial rearward side or axially frontward side of a torque converter, is engaged with the first pilot surface and the second pilot surface. A second balanced bearing is located either in the driving engine or the driven transmission.

Abstract: A system for venting a sealed, enclosed volume in the powertrain of an automotive vehicle includes a first housing, a second housing mechanically connected to the first housing, the first and second housings enclosing a volume, a seal located at an interface between the first and second housings for sealing said volume against passage of fluid; and a hollow vent tube having a length and including a first end communicating with the volume, and a second end spaced along the length from the first end, the second end permitting pneumatic fluid to enter and leave the vent tube.
