A first planet carrier is nonrotatably fixed to a stationary number and rotatably supports the first planet gears. A second planet gearset includes a second sun gear fixed for rotation with the first ring gear, a second ring gear non-rotatably fixed to the stationary member, and a set of second planet gears rotatably supported from a second planet carrier and which mesh with the second sun gear and the second ring gear.
