Heavy-Duty Cast Aluminum Transmission Pan 

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.

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.

The drain plug is 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.

Quality Item

Heavy duty pan with a drain plug. At 20k, replaced the fluid, filter and gasket while installing this pan. Couldn’t be happier with this product and giving my 10L80 a good chance at a long life.

Every GM 3.0L should have one

Huge difference in temp. From day 1 my 2021 Silverado 1500 3.0L was hitting 210 to 230 Temps here in Arizona summers. Dealer service said it was normal that they run Temps after constantly returning with temp concerns. I installed the pan at 45000 mile oil change. Now temps at the peak of summer are 190 to 200 when sitting in traffic.
After installing I took it back to the dealer and they were shocked by the difference in temps.

Getting the oversized tranny cooler for peace of mind towing next. Great product.
