ABSTRACT:
The present invention provides an assembly for use in a transmission that includes a first rotating member having a first portion and a second portion, the second portion having an outer diameter greater than an outer diameter of the first portion and having a bore with an open end. An annulus has a port for providing a fluid and is disposed proximate to the first portion. A second rotating member is at least partially located within the bore and extends from the open end. A first passage is connected to the port of the annulus and a second passage is connected to the first passage. The second passage is located through the second portion. A third passage is connected to the second passage and is located in the second rotating member. Fluid is able to flow from the port through the passages to provide fluid to the second rotating member.
