2019-2025 RAM 2500/3500 Aisin AS69RC Bar and Plate Transmission Cooler

Aisin Bar and Plate Transmission Cooler

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 Aisin 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 340 cubic-inch core – that’s 81% larger than the stock cooler. The 13% 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 30°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.

Note: add PPE Thermostat Bypass Valve (SKU 225065100) for maximized cooling performance.
