The PPE 124067000 Bar & Plate Transmission Cooler helps prevent the transmission on your 2020-2024 GM 3.0L Duramax LM2 from overheating. This Transmission Cooler features a bigger effective cooling area and thicker core which enables it to draw 200% more heat from your transmission fluid compared to the factory cooler. A temperature drop of up to 45-degrees has been observed with a PPE cooler installed under the same operating conditions.

PPE constructs the Bar and Plate Transmission Cooler with high-quality aluminum.
