The PPE 228051020 Deep Transmission Pan is the perfect choice for your 5.9 Cummins Truck. With large 3/4 inch cooling fins outside and 6 inch overall depth, this transmission pan will keep your truck's transmission running cooler and last longer. The stainless steel drain plug and robust side ribs provide additional strength, while the deep baffles prevent sloshing and transfer heat. The 1/8 and 1/4 inch NPT stainless temperature access ports allow you to monitor your transmission's temperature, while the included heavy-duty MP-15 gasket ensures a tight seal.
