PPE Power Heavy-Duty Cast Aluminum Transmission Pan Brushed Finish (128051410) - 2020-2026 GM 2500/3500 6.6L Duramax
Upgrade your 10-speed transmission with the PPE Power Heavy-Duty Cast Aluminum Transmission Pan. Designed for 2020-2026 GM 2500/3500 6.6L Duramax, this pan helps control heat, improve durability, and add service-friendly protection for towing, hauling, performance use, and daily driving. With 4 quarts of added fluid capacity, it gives the transmission more thermal reserve when temperatures climb.
Built from A356-T6 heat-treated cast aluminum, this PPE transmission pan is engineered to transfer heat more effectively than the factory pan while adding strength where it matters. The premium brushed finish gives the underside a clean, purpose-built look, while external cooling fins, internal baffles, reinforced gussets, magnetic service hardware, and an integrated NPT port make it a strong upgrade for long-term transmission reliability.
