PPE Bar and Plate Transmission Cooler

2015–2018 Ram 2500 / 3500

224064000

Overview:

The PPE Bar and Plate Transmission Cooler is a high-performance upgrade designed specifically for 2015 to 2018 Ram 2500 and 3500 trucks. Transmission overheating is a leading cause of premature transmission failure, resulting in clutch pack slipping, erratic shifting, and fluid degradation. This cooler addresses those issues by providing superior heat dissipation to maintain optimal transmission temperatures, extending the life and reliability of your vehicle’s transmission system.

Built for truck owners who demand durability and consistent performance under heavy loads or towing conditions, the PPE cooler ensures your transmission stays cooler even in the most demanding environments. Its advanced design offers a significant improvement over the factory transmission cooler, making it an essential upgrade for anyone looking to protect their investment and improve transmission longevity.

Key Features:

This transmission cooler combines innovative engineering with robust materials to deliver exceptional cooling performance:

• Massive 360 cubic-inch core, 118% larger than the stock cooler for enhanced cooling capacity
• 28% larger frontal area increases airflow exposure, improving heat dissipation efficiency
• Dense, louvered external fins maximize heat transfer to ambient air, achieving up to a 30°F temperature drop
• Heavy-duty bar and plate construction offers greater cooling mass and flow capacity compared to factory tube and fin designs
• All-aluminum build provides superior pressure resistance and durability for demanding applications
• Designed to maintain optimal transmission fluid temperatures under heavy towing, hauling, and off-road conditions
• Recommended to pair with PPE Thermostat Bypass Valve (SKU 225065000) for maximized cooling efficiency
• Direct fitment for 2015–2018 Ram 2500 and 3500 models; not compatible with 2013–2014 Ram Cummins trucks due to different cooling system layouts

Construction & Design:

The PPE transmission cooler features a rugged all-aluminum bar and plate design, which is a significant upgrade over the factory tube and fin style. This construction provides a larger cooling surface area and improved fluid flow, resulting in more effective heat transfer. The cooler’s dense, louvered fins are engineered to maximize airflow and dissipate heat quickly, ensuring your transmission fluid remains within safe operating temperatures.

Its robust aluminum construction also offers excellent resistance to pressure and corrosion, making it well-suited for heavy-duty and performance applications where reliability is critical. The cooler’s design balances size and efficiency, fitting seamlessly into the Ram 2500 and 3500 engine bays without requiring extensive modifications.

Installation & Fitment:

The PPE Bar and Plate Transmission Cooler is designed for direct bolt-on installation in 2015 through 2018 Ram 2500 and 3500 trucks. Installation typically requires no major modifications, making it a straightforward upgrade for experienced DIYers or professional installers. For optimal performance, it is recommended to install the PPE Thermostat Bypass Valve (SKU 225065000) alongside the cooler to ensure proper fluid flow and temperature regulation.

Please note this cooler is not compatible with 2013–2014 Ram Cummins trucks due to their unique cooling system configuration, including larger power steering coolers and dual radiators.

What's Included:

• One PPE Bar and Plate Transmission Cooler (360 cubic-inch core)
• Mounting hardware and brackets for secure installation
• Detailed installation instructions

Ideal For:

This transmission cooler is ideal for Ram 2500 and 3500 owners who frequently tow heavy loads, haul large payloads, or operate their trucks in high-temperature or demanding environments. It is especially beneficial for those looking to extend the service life of their transmission by preventing overheating and maintaining consistent fluid temperatures. Whether you use your truck for work, recreation, or performance driving, the PPE cooler provides peace of mind and enhanced transmission protection.
