The aFe BladeRunner transmission pan 46-71220B is precision-machined from aluminum alloy and engineered to replace the factory stamped steel transmission pan with a unit that runs cooler, holds more transmission fluid, and provides significantly greater protection during extreme driving conditions. Built specifically for the 2020-2021 Ford F-250 Super Duty, the 46-71220B features deep machined cooling fins across the exterior surface that increase surface area and dissipate heat into the ambient air, while the reinforced drain plug boss provides a long-lasting seal even after repeated service intervals. This is a direct bolt-on replacement using factory gasket surfaces and factory mounting hardware.

Yes. The 46-71220B includes a magnetic drain plug and the gasket or sealing hardware required for installation. Always use a new gasket when installing to ensure a leak-free seal at the mating surface.
How much additional fluid capacity does this pan add?Additional capacity varies by platform. The increased reservoir depth adds extra transmission fluid volume compared to the factory pan, which helps maintain consistent fluid temperatures and reduces the risk of thermal breakdown during extended high-load operation. Check the aFe Power product page for exact capacity figures for your application.
Does the magnetic drain plug capture ferrous debris?Yes. The included magnetic drain plug attracts fine ferrous particles circulating in the transmission fluid, trapping them at the drain point rather than recirculating them through bearings and machined surfaces. Inspect the magnet at every drain interval.
Is this pan compatible with my aftermarket oil cooler?The 46-71220B uses the same oil gallery port locations as the factory pan. If your existing cooler connects to factory oil gallery ports on the block or filter housing rather than the pan itself, it remains compatible. Confirm your specific cooler connection point before ordering.
Will this pan fit with aftermarket crossmembers or skid plates?The 46-71220B matches the factory pan profile. If you have aftermarket suspension or underbody protection, test-fit before final installation to confirm clearance with the increased depth of the aluminum pan versus the factory stamped steel unit.
How do I prevent leaks during installation?Clean both the block and pan mating surfaces thoroughly. Use the supplied gasket or apply a thin bead of the appropriate RTV sealant as specified in the instructions. Torque all pan bolts in a cross pattern to factory specification. Never over-torque aluminum pan bolts, as this can crush the sealing surface.
Is this compatible with my factory undertray or splash shield?In most applications, the factory undertray and splash shield are compatible. If the aluminum pan adds depth compared to the factory unit, a minor gap in the undertray is normal and does not affect function. Confirm fitment visually during installation.
What is the warranty on this oil pan?aFe Power backs this pan with a limited manufacturer warranty on materials and workmanship. Coverage does not include leaks resulting from improper installation, over-torquing of pan bolts, or failure to use the supplied gasket. Contact aFe Power for full warranty terms.
