Mishimoto Full Flow Thermal Bypass Valve Kit Most Ram 6.7L Cummins Models | Improved Cooling Efficiency | Transmission Cooling Upgrade
Overview
The Mishimoto Full Flow Thermal Bypass Valve Kit is a direct upgrade designed specifically for most Ram 6.7L Cummins models, addressing a critical weak point in the stock transmission cooling system. This valve replaces the factory in-line thermal bypass valve found in the Aisin AS69RC transmission, which controls fluid flow to the transmission cooler based on fluid temperature. The stock valve’s internal thermostat is prone to failure, often resulting in restricted fluid flow and elevated transmission temperatures that can lead to premature wear or failure. This Mishimoto kit eliminates that risk by providing full fluid flow to the transmission cooler at all times.
Engineered with precision CNC-machined billet aluminum, this thermal bypass valve kit not only enhances durability but also improves cooling performance. The design removes the internal thermostat, allowing continuous transmission fluid circulation through the cooler regardless of temperature. Additionally, the valve body features machined cooling fins and optimized internal passages to maximize heat dissipation and fluid flow efficiency. Mishimoto’s commitment to quality and performance ensures this valve kit stands out as a reliable and long-lasting solution for demanding Ram Cummins owners.
For Ram 6.7L Cummins owners who tow heavy loads, operate in warm climates, or simply want to extend the life of their transmission, this full-flow thermal bypass valve kit offers tangible benefits. By maintaining lower transmission fluid temperatures, it helps prevent overheating and reduces stress on transmission components. This upgrade is a practical and effective way to enhance the reliability and longevity of your Ram’s drivetrain, especially under heavy-duty conditions.
