GM 6.6L Duramax 10L1000 Transmission

Excessive heat kills transmission life. As temperature rises, transmission fluid viscosity decreases, weakening the lubricating film that protects gears and bearings. This could cause premature wear and potential failure for your GM 6.6L Duramax 10L1000 Transmission.

Cast from high-grade A356.0-T6 aluminum alloy, the PPE transmission pan offers 4 quarts of additional fluid capacity, ensuring long-lasting heat management and performance.

The deep external cooling fins maximize the heat-wicking surface area, effectively dissipating heat to keep your transmission cool under pressure. These fins also add strength to the bottom of the pan and enhance impact resistance.

The built-in baffles at the bottom of the pan increase contact between the fluid and the cast-aluminum surfaces, enhancing heat transfer. These baffles also reduce fluid sloshing, ensuring consistent fluid pickup and stable transmission performance. Together with the longitudinal external fins, they form a stiff, cross-bracing structure, distributing loads better and increasing impact resistance.

A fluid level check standpipe ensures proper fluid level during the filling process. The drain plug and fluid level check plug are both equipped with a powerful, high-temperature-rated neodymium magnet that captures ferrous metal particles, providing additional protection for your transmission.

Keep your 10 speed transmission running longer, healthier, and cooler with PPE.
