The transmission optionally includes a first and a second planetary gearset, a first and a second clutch, and a brake. The system may be configured to separately engage these components in concert.

Motors may be arranged upstream or downstream of portions of a transmission, and they may be aligned parallel with or perpendicular to a drive axle.
