Abstract
A clutch hub is splined to a planetary ring gear and a second rotating element, coupling the two elements. The spline defines a number of axial fluid distribution channels that conduct fluid from an interior radial passageway beside the ring gear to exterior radial passageways over the ring gear. These axial passageways permit packaging the clutch pack directly over the ring gear without drilling holes in the hardened gear material. The axial channels may be defined by radial space between the splined components. Alternatively or additionally, some spline teeth may be omitted to define larger axial channels.
