Give Your Transmission The Cooling Advantage It Needs To Last

If you rely on your truck to handle real work, keeping transmission temperatures under control is one of the smartest upgrades you can make. The PPE Deep Transmission Pan is built to give your 10L1000 the extra capacity and cooling performance it needs when the load gets heavy. With an additional 1.5 quarts of fluid, your transmission gains more thermal stability, which helps maintain smooth operation during towing or long drives. Additionally, the external cooling fins are constantly working to pull heat away, helping protect your transmission from the kind of stress that leads to early wear. This is the kind of upgrade that pays off over time by keeping everything running more consistently. The raw finish gives you a clean, functional look that also leaves room for customization if you want to make it your own. Designed for 2024-2026 Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L L8T gas engine, it is a practical improvement that supports both performance and longevity.

Engineered Heat Management System Built For Strength And Stability

The PPE 128052400 transmission pan is constructed from A356.0-T6 heat-treated cast aluminum, offering excellent strength and thermal conductivity in demanding conditions. This material allows heat to transfer away from the fluid more efficiently than traditional stamped steel designs. Inside the pan, deep internal baffles increase fluid contact with the aluminum surface, improving heat absorption while also reducing fluid movement during acceleration or uneven terrain. At the same time, tall external fins expand surface area and promote airflow, helping lower overall transmission temperatures. These features work together to form a rigid cross-braced structure that enhances strength and impact resistance. The stainless steel service plugs are equipped with high-temperature Neodymium magnets that capture metal particles, helping protect internal components from contamination. A built-in standpipe ensures accurate fluid level setting during installation and maintenance. Compatible with OEM gaskets and filters, this design delivers a balanced combination of durability, cooling efficiency, and long-term reliability.
