2019–2024 Ram 2500 / Ram 3500 6.7L Cummins
MMTC-RAM2-TBV
Overview:
The Mishimoto Thermal Bypass Valve is a precision-engineered upgrade designed specifically for the 2019 to 2024 Ram 2500 and Ram 3500 equipped with the 6.7L Cummins engine. This critical component manages the flow of transmission fluid to the cooler, ensuring your transmission operates within optimal temperature ranges. Unlike the stock thermal bypass valve, which can fail and cause overheating, Mishimoto’s valve features a durable, serviceable thermostat that opens earlier to improve cooling efficiency without risking over-cooling.
Built for Ram owners who demand reliability and longevity from their drivetrain, this valve enhances transmission cooling performance, protects against heat-related damage, and offers a customizable bypass option for extreme climates. It’s an essential upgrade for anyone looking to maintain peak transmission health under heavy loads or harsh conditions.
Key Features:
Engineered for superior transmission fluid management, the Mishimoto Thermal Bypass Valve offers:
Construction & Design:
The Mishimoto Thermal Bypass Valve is crafted from high-quality CNC-machined aluminum, providing superior strength and thermal conductivity compared to the stock plastic valve. Its black anodized finish protects against corrosion and wear, ensuring a long service life even under demanding conditions. The valve’s integrated cooling fins increase surface area to dissipate heat more effectively, helping maintain optimal transmission fluid temperatures.
The valve features a fully serviceable thermostat that can be replaced without removing the entire unit, allowing for easy maintenance and customization. The thermostat is calibrated to open earlier than the factory unit, promoting quicker fluid circulation to the cooler and reducing the risk of overheating during heavy towing or extended operation.
Installation & Fitment:
Installation of the Mishimoto Thermal Bypass Valve is straightforward and requires no modifications to your Ram 2500 or 3500’s transmission cooling system. It is a direct replacement for the factory valve on 2019–2024 models equipped with the 6.7L Cummins engine. The included bypass plug can be swapped using just a wrench, allowing you to tailor cooling performance for seasonal or climate-specific needs.
This valve fits the following Ram models and trims:
What's Included:
Ideal For:
This thermal bypass valve is ideal for Ram 2500 and 3500 owners who tow heavy loads, operate in hot or variable climates, or simply want to improve the reliability and longevity of their transmission. It is especially beneficial for those who experience transmission overheating issues due to thermostat failure in the stock valve or who want to optimize transmission fluid temperatures for enhanced performance and durability.
Mishimoto is a performance cooling brand offering aluminum radiators, intercoolers, oil coolers, hoses, and supporting hardware built to manage heat on hard-driven street and track vehicles. For boosted setups and towing/off-road rigs alike, Mishimoto upgrades are designed to increase cooling capacity and reliability where factory systems can become a limitation.
