The present invention is directed to a sealing cap assembly (10) of the type that is particularly adapted for use in closing and venting the access aperture (60) of a transmission housing (58). The embodiment of the sealing cap assembly (10) disclosed, has a body portion (15) and a cap portion (20). The body portion (15) has a radially outermost extent with at least one thread path (51 and/or 52) extending along, and being recessed inwardly with respect to, the outermost extent of the body portion (15). At least one hollow cubicle (46, 47, 48 or 49) is provided interiorly of the body portion (15). Port means (73 and/or 74) penetrate the body portion (15) in order to provide communication between at least one the thread paths (51 and/or 52) and the hollow cubicle (46, 47, 48 or 49). The cap portion (20) is attached to the body portion (15), but in spaced relation upwardly thereof, in order to provide communication between the hollow cubicle (46, 47, 48 or 49) and the environment to which the cap portion (20) is exposed.
