    Abstract: 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.

    Abstract: A retention ring is configured to retain components within a transmission assembly. The retention ring has an annular main body defining an opening through a center thereof. The annular main body defines an outer curved surface and an inner curved surface, the annular main body having a distal face disposed in a distal plane and a proximal face disposed in a proximal plane. A first set of retention features extend from the inner curved surface, and a second set of retention features from the outer curved surface. One of the sets of retention features is configured to engage a backing plate or an outer member, and at least one of the sets of retention features is entirely disposed between the proximal plane and the distal plane. A transmission assembly includes the retention ring and an adjacent external snap ring.
