Moroso Transmission Pans As the undisputed leader in oil pan technology, Moroso has turned its attention to the design and manufacturing of premium quality Transmission Pans. Unlike heavier cast versions offered by others, Moroso Transmission pans are fully fabricated entirely from lightweight aluminum and feature a one-piece billet rail to ensure leak free sealing. Precise CNC manufacturing and TIG welding prevent distortion for a perfect fit every time. Pans with extended depths (see diagrams for dimensions) reduce temperature and improve oil control during acceleration and braking. We've included filter spacers on extended depth versions where needed. All Moroso Transmission pans include dual fittings(except 42050) with magnetic drain plugs and pan mounting hardware consisting of steel studs and convenience. Pan gaskets are not included and must be purchased separately.
