Upgrade from the stock stamped-steel transmission pan to the PPE Heavy-Duty Cast Aluminum Deep Transmission Pan for complete drainage, improved durability, enhanced cooling, and superior transmission protection.
The stock fluid pan has limited capacity, providing little thermal buffering, and its thin sheet metal construction lacks the strength needed for road debris/obstacles. In addition, the stock drain nut protrudes above the bottom of the transmission pan, trapping over 1 quart of old fluid. This retained fluid, filled with metal shavings, mixes with the fresh fluid immediately, accelerating wear on transmission components.
Excessive heat kills transmission life. As temperatures rise, transmission fluid viscosity decreases, weakening the lubricating film that protects gears and bearings. This could cause premature wear and potential failure. The external cooling fins remain flush with the stock skid plate. This design maximizes the effect of underbody airflow for superior cooling and heat dissipation, while ensuring smooth airflow, reducing flow separation or turbulence.
The PPE Transmission Pan has deep external cooling fins, resulting in a 2.24X larger external surface area.
The PPE Deep Transmission Pan increases the transmission fluid capacity by industry-leading 4.3 quarts. Higher transmission fluid capacity means higher thermal stamina and less chance of overheating (because it takes longer to heat up a larger volume of fluid). It also dilutes the contaminants in the system, prevents sludge formation, reduces wear, and extends transmission life.
Some competitors choose to line up the internal and external fins. This design leaves unsupported gaps between the fins which makes the pan susceptible to deformation. The internal baffles in the PPE Pan are purposely laid out diagonally. Together with the longitudinal external fins, they form a stiff, cross-bracing structure, distributing loads better and increasing rigidity and structural integrity.
The PPE Pans are manufactured using permanent mold casting. The steel molds in this process provide better dimensional accuracy and smoother surface finish when compared to sand molds. This process significantly reduces porosity and internal defects, resulting in better integrity, a denser structure, and higher strength. We use A356.0-T6 heat-treated aluminum for our casting, a strong, durable, corrosion-resistant, and thermally efficient alloy. Our pans all go through a process called shot peening, which hardens the surface, improves fatigue strength, and relieves the internal stress induced by heat treatment processes. This is also why the surface of the pans has a “rougher” texture.
A large, 304 stainless-steel drain plug is included. It’s equipped with a powerful high-temperature rated neodymium magnet to pull ferrous metal shavings out of the fluid, providing additional protection to the gears and bearings. The drain plug resides in a recessed area and is protected by the deep external fins, eliminating any chance of getting ripped away by road debris/obstacles.
