Product Details

When you're towing heavy loads or driving in hot climates with your 2019-2024 Ram 2500, keeping your transmission fluid cool is critical. The transmission is responsible for handling the massive torque from the 6.7L Cummins engine, and excessive heat can quickly lead to damage. While the stock transmission cooler helps, the factory thermal bypass valve can sometimes prevent fluid from reaching it until the transmission is already hot.

Mishimoto has developed a full-flow thermal bypass valve upgrade designed to eliminate this issue. This valve removes the restrictive thermostat found in the stock unit, ensuring that transmission fluid is always directed to the cooler, regardless of temperature. This constant flow is especially beneficial for trucks in warm regions, those frequently towing, or any owner looking to maximize their transmission's cooling efficiency. The CNC-machined aluminum body not only looks good but also features internal passages for improved flow and cooling fins to help dissipate heat.

This kit is built to last and comes with Mishimoto's Lifetime Warranty, offering a durable solution for keeping your transmission running cool under demanding conditions.
