PPE Heavy Duty Transmission Cooling Upgrade Kit For 20-24 GM 3.0L Duramax Diesel

Boost your transmission performance with this PPE Bar and Plate Transmission Fluid Cooler. A bigger effective cooling area and thicker core enable the PPE cooler to draw 200% more heat from your transmission fluid compared to the factory cooler. We observed up to 45°F temperature drop with a PPE cooler installed under the same operating conditions. The PPE Bar and Plate Transmission Cooler are made of high-quality aluminum, with specially engineered fin construction to maximize cooling efficiency while maintaining pressure drop as low as possible. It is a direct replacement with no modification or additional parts needed. Reuse factory cooler hardware for installation.

PPE’s Heavy-Duty DEEP 10L80 Transmission Pan holds an extra 4 quarts of fluid and is cast from high-quality aluminum alloy for strength and optimal heat dissipation. Simply stated, more is always better when it comes to transmission fluid. Higher volumes of fluid take longer to heat up allowing for more stable transmission temperatures which help to extend transmission life. Cast gussets provide strength and overall robustness. Internal heat sinks wick heat and acts as baffles to reduce fluid sloshing. External fins add surface area and use free-flowing air to radiate heat. The PPE Heavy-Duty DEEP Aluminum Transmission Pan also features a high-power Neodymium magnet-equipped billet stainless steel drain plug to catch and hold harmful ferrous metal contaminants keeping them out of the transmission internals.

Add another measure of protection and increase fluid flow to the transmission cooler. Increase cooling capacity with this easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the GM 10L80 10-Speed transmission. The OEM part has restrictive internal passages. When the OEM valve fails in the closed position, transmission fluid doesn’t reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to overheat dangerously. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components. The PPE Bypass Valve eliminates the extremely restrictive mechanical factory valve, maximizing fluid flow to and from the transmission cooler. For further protection, a Neodymium magnet-equipped service plug with O-ring seal has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory bypass valve does not have this feature.
