2020-2025 Duramax L5P PPE Transmission Cooler Bar & Plate (124064600)
Excessive heat is the number one contributor to transmission failures and can cause clutch pack slipping, clunky shifting, fluid breakdown, etc. Constant overheating can reduce the transmission service life by 50% or more. The PPE bar and plate transmission cooler provides the proper cooling that your transmission needs to stay healthier and longer. The PPE all-aluminum transmission cooler features a massive 231 cubic-inch core – that’s 175% larger than the stock cooler. The 37% larger frontal area increases its airflow exposure, enhancing heat dissipation. Its dense, louvered external fins maximize heat transfer to ambient air, helping achieve a temperature drop of up to 45°F to keep your transmission within the optimal temperature range – even under demanding conditions.
The PPE cooler’s bar and plate construction is a heavy-duty upgrade over the factory tube and fin design, delivering significantly greater cooling mass and flow capacity for true performance gains. Its all-aluminum build also offers superior pressure resistance and durability, making it ideal for performance applications.
