2019-2024 3.0L Duramax Bar & Plate Transmission Fluid Cooler

Boost your transmission performance with this 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.  It was observed that up to 45°F temperature drops 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.
