The transmission is the backbone of your RAM. It’s responsible for transmitting large amounts of torque from your 6.7L Cummins powerplant, and that torque generates heat. If that heat isn’t dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it. The stock cooling system of both the 68-RFE and Aisin AS69RC utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler. The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler and the transmission can overheat. That's why Mishimoto has developed an improved thermal bypass valve kit for your 2019+ Dodge Ram 6.7L Cummins. Our CNC-machined aluminum thermal bypass valve not only looks better than the stock unit, but it performs better too. The Mishimoto thermal bypass valve utilizes a replaceable thermostat that is more durable than the stock thermostat and opens about 10 F earlier. This allows fluid to flow to the cooler sooner, without over-cooling. For owners in hot climates, the Mishimoto valve includes a bypass that allows full flow to the transmission cooler, regardless of temperature. The bypass can be easily swapped out with only a wrench for summer or winter driving. The Mishimoto thermal bypass valve flows better in both configurations than the stock valve for more effective cooling. Cooling fins machined into the valve body add even more heat dissipation. This 2019+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit is built to last a lifetime with a durable black anodized finish and our Mishimoto Lifetime Guarantee.
  • Product is included with a thermostat bypass for constant cooling in hot climates

Description

The Mishimoto thermal bypass valve kit is designed specifically for your 2019 and newer Ram 2500 and 3500 with the 6.7L Cummins engine, offering improved cooling performance and durability. The transmission is crucial for transmitting high torque from your engine to the wheels, and managing the heat generated during this process is essential to prevent damage. This kit ensures your transmission fluid reaches the cooler more efficiently, reducing the risk of overheating and extending the lifespan of your transmission.
Constructed from CNC-machined aluminum, the Mishimoto bypass valve not only enhances durability but also features a sleek black anodized finish that resists corrosion. It includes a replaceable thermostat that opens approximately 10°F earlier than stock, allowing transmission fluid to flow to the cooler sooner, especially beneficial in hot climates. This early flow helps maintain optimal transmission temperatures, ensuring your vehicle performs reliably under demanding conditions.
The kit also offers a full-flow bypass option, which can be easily swapped in with a wrench, providing constant cooling regardless of temperature. This feature is particularly advantageous during summer months or in high-temperature environments. Machined cooling fins integrated into the valve body further improve heat dissipation, enabling superior thermal management. The fully serviceable thermostat promotes rapid warm-up in cold weather, maintaining consistent transmission operation across temperature ranges.
Designed with longevity in mind, the Mishimoto thermal bypass valve kit is backed by a lifetime guarantee. Its improved flow characteristics and durable construction make it a valuable upgrade for heavy-duty use or enthusiasts seeking enhanced transmission cooling performance. Proper installation ensures your vehicle remains protected from overheating issues, contributing to better overall drivetrain health and reliability.

Features:

  • Constructed from CNC-machined aluminum with a black anodized finish for durability and corrosion resistance
  • Includes a replaceable thermostat that opens approximately 10°F earlier than stock for faster cooling flow
  • s a full-flow bypass option for constant cooling in hot climates, easily swappable with a wrench
  • Machined cooling fins on the valve body enhance heat dissipation for improved thermal management
  • Fully serviceable thermostat ensures rapid warm-up during cold weather, maintaining optimal transmission operation
