Mishimoto - misMMTC-RAM-TBV - 2013+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit

The transmission is the backbone of your 2013- 2018 Dodge Ram 6.7L Cummins. It's responsible for transmitting up to 930 lb-ft of torque from the engine to the wheels. That much power generates a lot of heat and if that heat isn?t dissipated it can destroy your transmission. The transmission cooler does a good job of keeping transmission 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 2013?2018 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 2013-2018 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. High-performance component designed to enhance thermal efficiency, durability, and reliability under demanding conditions. Engineered to support optimal temperature control and system performance across applications.

• Includes fully serviceable thermostat for fast warm-up in cold climates and thermostat bypass for constant cooling in hot climates
• Included 160 F thermostat opens earlier than stock for improved cooling
• Direct-fit for 2013-2018 Dodge Ram 6.7L Cummins
• Increased flow over stock bypass valve
• Mishimoto Lifetime Warranty

The Mishimoto Thermal Bypass Valve Kit is designed for 2013–2018 Dodge Ram 6.7L Cummins applications using the 68-RFE or Aisin AS69RC transmission. It replaces the stock in-line thermal bypass valve with a CNC-machined aluminum valve designed to improve transmission fluid flow and thermal control.

The included replaceable 160°F thermostat opens approximately 10°F earlier than the stock thermostat, allowing transmission fluid to reach the cooler sooner without overcooling. For hot-climate or high-temperature driving, the included bypass can be installed to provide full flow to the transmission cooler regardless of fluid temperature. The bypass configuration can be changed with a wrench for seasonal driving conditions.

Cooling fins machined into the valve body support additional heat dissipation, while the durable black anodized finish is designed for long-term service. The kit provides increased flow over the stock bypass valve and includes a Mishimoto Lifetime Warranty.

What's Included: Thermal bypass valve, replaceable 160°F thermostat, and thermostat bypass.

Fitment: Direct-fit for 2013–2018 Dodge Ram 6.7L Cummins applications. Listed fitment includes 2014 Ram 2500 and 2014 Ram 3500.

Features:
