Abstract
A powertrain has an engine with a crankshaft. The powertrain includes a planetary gear set having a first, a second, and a third member. The first member is connected for common rotation with an input member. A first clutch is selectively engageable to operatively connect the crankshaft with the input member. A second clutch is selectively engageable to ground the input member with a stationary member. An electric motor/generator has a rotor operatively connected for common rotation with the second member. An output member is provided, with a set of intermeshing gears configured to transfer torque from the third member to the output member. A first gear pair and a second gear pair are operable by engagement of a first synchronizer and a second synchronizer, respectively, to provide two different fixed ratios between the input member and the output member.
