A planetary gear assembly for transferring torque in a transmission includes first and second planetary gear sets, each including a ring gear, a sun gear, and a carrier bearing a plurality of planet gears. A bridge portion connects a first carrier of the first planetary gear set to a second ring gear of the second planetary gear set. The bridge portion may be disposed radially outward of the first sun gear, and the bridge portion may be connected to an outer side of the first carrier. In some examples, a first ring bearing assembly is constrained by the first ring gear and the bridge structure; a first carrier bearing assembly is constrained by a first case portion and a bridge extension extending from the first carrier; and a second ring bearing assembly is constrained by a second case portion and a second bridge extension extending from the second ring gear.
