A composite transmission housing includes resin transfer molding or vacuum assisted resin transfer molding manufacturing processes combined with discontinuous fiber preforms. The preforms are assembled in a prepared injection and cure mold with additional details and fillers. The preforms are constructed such that the preforms are assembled into the mold in a specific order to assure proper arrangement. Using a combination of vacuum and pressure, a resin is injected into the mold to completely infuse the assembled preforms. At completion, the mold is heated to the resin cure temperature and held at this temperature for sufficient time to insure complete cure.
