Mishimoto Thermal Bypass Valve Kit Most Dodge Ram 6.7L Cummins Models | Full Flow Cooling | Transmission Cooling Upgrade

Overview

The Mishimoto Thermal Bypass Valve Kit is a critical upgrade designed for the 2013-2018 Dodge Ram 6.7L Cummins equipped with either the 68-RFE or Aisin AS69RC transmissions. This valve replaces the stock in-line thermal bypass valve that regulates transmission fluid flow to the cooler based on temperature. Unlike the factory valve, which contains a thermostat prone to failure and can restrict fluid flow, the Mishimoto valve provides full fluid flow to the transmission cooler at all times, ensuring optimal cooling performance.

Engineered with precision CNC-machined aluminum and finished with a durable silver anodized coating, this valve not only improves reliability but also enhances heat dissipation through integrated cooling fins. Mishimoto’s design philosophy focuses on durability and efficiency, eliminating the common failure points of the stock valve while improving fluid flow dynamics for better thermal management.

For Dodge Ram owners who tow heavy loads, operate in warm climates, or simply demand the best transmission cooling, this full-flow thermal bypass valve kit offers tangible benefits. By maintaining lower transmission fluid temperatures, it helps extend transmission life and improves overall drivetrain reliability under demanding conditions.
