Abstract
A snubber for an automotive transmission includes a generally flat surface configured to limit radially-outward movement of a drive member that transfers torque from a transmission gearbox output to a differential input. A mouth of the snubber is fluidly coupled to an internal cavity that capturing transmission fluid as the fluid is moved around due to movement of the drive member. A wing of the snubber extends from the generally flat surface toward the drive member. The wing has a hollow interior fluidly coupled to the internal cavity. A concave outer surface is located outside of and adjacent to the mouth. The concave surface deflects a portion of the fluid, preventing that portion from entering the mouth. This increases the flow of fluid away from the drive member which can lead to drag.
