Whether you use your Ram for towing heavy loads, fleet work, or spirited driving, this direct-fit cooler provides enhanced cooling performance to protect your transmission and extend its lifespan.

By upgrading from the stock transmission cooler to Mishimoto’s advanced design, you reduce fluid temperatures significantly, improving transmission reliability and shifting performance. This cooler is a vital upgrade for anyone looking to maintain peak transmission health in high-stress environments.

Key Features:

Built with cutting-edge cooling technology, the Mishimoto Transmission Cooler offers superior heat dissipation and flow efficiency. Key features include:

• Tube-and-fin core design with internal fins to maximize cooling surface area and fluid contact
• 64% thicker core than stock for increased heat rejection capacity
• Three additional rows of cooling fins for enhanced thermal transfer
• Reduced flow restriction compared to factory coolers, promoting better fluid circulation

Construction & Design:

The Mishimoto Transmission Cooler features a robust tube-and-fin core constructed from high-quality aluminum for excellent thermal conductivity and corrosion resistance. Internal fins within the tubes increase the fluid’s exposure to cooling surfaces, optimizing heat transfer efficiency. The thicker core and additional fin rows provide a substantial improvement over the OEM cooler, ensuring your transmission fluid stays cooler even under heavy loads or extreme conditions.

Precision engineering ensures a perfect fit for the Ram 2500 and 3500 models listed, maintaining factory mounting points and preserving the integrity of your vehicle’s front-end components.

Installation & Fitment:

Installation is straightforward and requires no cutting, trimming, or other modifications. The cooler mounts directly using existing bolt-on tabs, allowing your radiator and A/C condenser to remain securely in place. This design reduces installation time and cost, making it accessible for both professional installers and experienced DIY enthusiasts.
