PPE Bar and Plate Transmission Cooler

2015–2018 Ram 2500 / 3500 6.7L Diesel

Part #: 224064000

Overview

The PPE Bar and Plate Transmission Cooler is a premium cooling solution engineered specifically for 2015 to 2018 Ram 2500 and 3500 trucks equipped with the 6.7L diesel engine. Transmission overheating is a common cause of premature failure, leading to clutch pack slipping, erratic shifting, and fluid breakdown. This cooler combats those issues by delivering superior heat dissipation, maintaining optimal transmission fluid temperatures even under heavy towing, hauling, or off-road conditions.

Designed for truck owners who demand durability and reliable performance, the PPE cooler significantly outperforms the factory unit. It extends transmission life and enhances overall vehicle reliability, making it an essential upgrade for anyone looking to protect their investment and ensure consistent transmission operation in demanding environments.

Key Features

Combining advanced engineering with rugged materials, the PPE Bar and Plate Transmission Cooler offers exceptional cooling capacity and durability:

• Massive 360 cubic-inch core, 118% larger than the stock cooler for superior heat rejection
• 28% larger frontal area increases airflow exposure, enhancing cooling 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 provides greater cooling mass and fluid flow compared to factory tube and fin designs
• All-aluminum build ensures excellent pressure resistance and corrosion durability for heavy-duty use
• Maintains optimal transmission fluid temperatures during heavy towing, hauling, and off-road driving
• Recommended to pair with PPE Thermostat Bypass Valve (SKU 225065000) for maximum cooling efficiency
• Direct bolt-on 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 robust all-aluminum bar and plate design, a significant upgrade over the factory tube and fin style. This design increases the cooling surface area and improves fluid flow, resulting in more effective heat transfer and better temperature control.

Its dense, louvered fins are engineered to maximize airflow and rapidly dissipate heat, ensuring transmission fluid remains within safe operating temperatures. The heavy-duty aluminum construction also offers superior resistance to pressure and corrosion, making it ideal for demanding applications where reliability is critical.

Despite its larger size and enhanced cooling capacity, the cooler is designed to fit seamlessly into the Ram 2500 and 3500 engine bays without requiring extensive modifications, maintaining a clean and professional installation.

Installation & Fitment

The PPE Bar and Plate Transmission Cooler installs easily with a direct bolt-on fitment for 2015 through 2018 Ram 2500 and 3500 trucks. Installation typically requires no major modifications, making it accessible for experienced DIYers and professional installers alike.

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.
