Give Your Allison The Cooling Capacity It Deserves Under Load

When you start putting real demand on your truck, heat becomes one of the biggest threats to your transmission’s lifespan. The PPE Deep Transmission Pan is built to give your 10L1000 the extra fluid capacity and cooling performance it needs to stay protected. With an additional 1.5 quarts of fluid, your transmission can better manage heat during towing, hauling, or long highway pulls. Additionally, the external cooling fins work constantly to pull heat away from the fluid, helping maintain consistent performance even when things get demanding. You will also appreciate the added confidence that comes from knowing your transmission is better protected from wear over time. The brushed finish gives it a clean, refined look that stands out without being flashy. Designed for 2024-2026 Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L L8T gas engine, it is a practical upgrade that delivers real benefits every mile.

Advanced Internal Structure Built For Heat Control And Durability

The PPE 128052410 transmission pan is engineered from A356.0-T6 heat-treated cast aluminum, offering excellent strength and thermal conductivity. This allows heat to transfer away from the transmission fluid more efficiently compared to factory 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 increase surface area and promote airflow, helping lower overall fluid temperatures. These elements work together to form a rigid cross-braced structure that enhances strength and impact resistance. The included stainless steel service plugs feature high-temperature Neodymium magnets that capture harmful metal particles before they circulate through the system. A built-in standpipe ensures accurate fluid level setting during installation and servicing. Compatible with OEM gaskets and filters, this design delivers both improved performance and long-term reliability.
