124064000 | PPE Performance Transmission Cooler Bar and Plate For GM 6.6L Duramax With Allison 1000 Transmission

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 211 cubic-inch core – that’s 105% larger than the stock cooler. The 20% 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 40°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 stacked plate 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.
