Extreme Duty Bar & Plate Transmission Cooler for 2013-2018 Ram 2500/3500 (68RFE & Aisin AS69RC)
When you’re hauling heavy, towing big, or stacking horsepower, your transmission is working overtime. Excessive heat is the #1 enemy of the 68RFE and Aisin AS69RC transmissions found in 2013-2018 Ram 2500/3500 trucks. The Extreme Duty Bar & Plate Transmission Cooler is designed to dramatically increase cooling efficiency, ensuring your transmission stays protected and performing at its best—no matter how hard you push your truck.
Engineered for Maximum Cooling
• 4X the Fluid Capacity of Stock – More fluid means better heat absorption and dissipation, allowing your transmission to maintain consistent, safe operating temperatures under extreme loads.
• Bar & Plate Core for Superior Heat Rejection – The heavy-duty bar & plate design provides exceptional cooling efficiency and structural strength, outperforming standard tube-and-fin or stacked plate coolers in both cooling performance and durability.
• Dual-Pass Flow for Enhanced Cooling Efficiency – Unlike traditional single-pass coolers, which allow fluid to flow through the core once before exiting, this dual-pass design forces transmission fluid to circulate through the cooling core twice before returning to the system. This extended exposure to cooling airflow maximizes heat dissipation, making it a must-have upgrade for heavy towing, high torque loads, and extreme conditions.
• Proprietary Heat-Wicking Powder Coating – To further enhance cooling performance, the exterior is treated with a heat-wicking powder coating that pulls heat away from the cooler, increasing efficiency and reducing transmission fluid temperatures.
• Aerospace-Grade Aluminum Construction – Built from premium aerospace-grade aluminum, this cooler is highly resistant to corrosion, extreme heat, and road debris, ensuring long-lasting reliability.
Built for Durability & Performance
• Internally & Externally TIG Welded – Unlike factory and mass-produced coolers that rely on crimped connections, this unit is fully TIG welded inside and out for maximum strength and leak resistance.
• Handles the Toughest Environments – Whether you’re climbing steep grades with a heavy trailer or making high-horsepower runs, this cooler keeps your transmission temps in check—helping to extend transmission life and prevent costly failures.
• Designed for Heavy Work & High Performance – Whether your Ram is a workhorse, tow rig, off-road monster, or high-horsepower street truck, this cooler ensures your 68RFE or Aisin transmission runs at optimal temperature in the most demanding conditions.
• Easy Installation – Designed for a seamless fit in 2013-2018 Ram 2500/3500 trucks, requiring minimal modifications for installation.
The Bottom Line
Heat kills transmissions. The Extreme Duty Bar & Plate Transmission Cooler is the ultimate solution for keeping your 68RFE or Aisin AS69RC running cool, no matter the conditions. With 4X the fluid capacity, aerospace-grade materials, TIG-welded construction, a dual-pass flow design, and a proprietary heat-wicking powder coating, this cooler is built to outlast and outperform anything on the market.
Cooler temps. Longer transmission life. Maximum reliability. Upgrade today.
