Vehicle drivetrain lubrication system

A vehicle drivetrain assembly, comprising:

• a housing having a housing interior part of which defines a lubricant bath in which lubricant is received, a housing inlet communicating with the housing interior, a housing outlet communicating with the housing interior, a first opening communicating with the housing interior and having a first axis, a second opening communicating with the housing interior and having a second axis, and a third opening communicating with the housing interior and being coaxial with the second opening;
• a reservoir carried by the housing and having a reservoir interior, a reservoir inlet communicating with the reservoir interior, and at least one reservoir outlet communicating with the reservoir interior;
• a conduit coupled at a first end to the housing outlet and coupled at a second end to the reservoir inlet, wherein at least part of the conduit extends above the housing interior relative to gravity, and the conduit is routed about an exterior of the housing;
• and
• a ring gear received within the housing interior for rotation relative to the housing, the ring gear is arranged so that part of the ring gear is within the lubricant bath and lubricant is displaced by the ring gear as the ring gear rotates relative to the housing and at least some of the displaced lubricant is routed from the housing interior to the reservoir interior through the lubricant conduit.
