ABSTRACT:
An improved lubrication system for a vehicular mechanical transmission (10) is provided. The transmission gearing (22-34) rotates in a dry sump (11) in the housing (12) and a reservoir (40) provides a sump of lubricant (42) below the level of the gearing. A pump (44) pumps lubricant from the reservoir through a filter (48) and into a distribution manifold (50) for filtered lubrication of the bearings (20) and/or other transmission elements.
