Heat exchange module

Systems and methods are presented herein for lubricating a differential assembly using a double baffle assembly. The differential assembly comprises a lubrication jet, an output gear, and the double baffle assembly. The output gear comprises openings and the lubrication jet is aligned with the openings in the output gear. The double baffle assembly comprises an inner baffle and an outer baffle that collectively form a slot aligned with the openings in the output gear. The inner baffle is configured to guide lubrication expelled from the lubrication jet towards the openings in the output gear, regardless of whether the differential assembly is in an engaged state or disengaged state.
