Apparatuses and systems of the present disclosure allow for more efficient delivery of oil to bearings and other rotating components of a planetary gear assembly in a transmission or differential of a vehicle. An oil delivery device that facilitates oil delivery to the rotating components of the planetary gear assembly has a disk shape with opposing axial sides and opposing radial surfaces. The opposing sides and surfaces define a chamber within the oil delivery device that receives oil through an opening extending circumferentially about one side of the oil delivery device and expels oil through an outlet extending through the opposing side. The radially inner, or bottom, surface facilitates retention, and reduces leakage, of oil from within the chamber so that a greater portion of oil received by the oil delivery device is delivered to the moving components of the planetary gear assembly.
