ABSTRACT:
A novel cover (10) for one end of the casing within which a vehicular transmission is housed and a unique method for making the cover. The cover (10) has a metallic body portion (12) within which a unitary manifold (40) has been cast in situ. The manifold (40) incorporates a plurality of conduits (A-E) which have been preformed and conjoined into the unitary manifold (40) that is precisely disposed within a mold. Molten metal is admitted into the mold to encapsulate the manifold (40) within the metallic body portion (12) of the cover (10). After the cover (10) has been cast, with the manifold (40) encapsulated therein, the cover (10) is removed from the mold, and only a relatively modest amount of machining operations are required to complete the cover (10).
