Fits select 2013-2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine.

The transmission in your heavy-duty Ram is tasked with managing up to 930 lb-ft of torque, generating significant heat during towing and hauling. The factory cooling system on both the 68-RFE and Aisin AS69RC transmissions relies on an in-line thermal bypass valve to regulate fluid flow to the external cooler. However, the internal thermostat in the stock valve is a known failure point; if it sticks, fluid cannot reach the cooler, leading to rapid transmission overheating and potential internal damage.

The Mishimoto Full Flow Thermal Bypass Valve Kit solves this vulnerability by eliminating the internal thermostat entirely. This ensures 100% fluid flow to the transmission cooler at all times, providing maximum cooling efficiency for trucks in warm climates or those frequently used for heavy towing. CNC-machined from billet aluminum, the valve body features integrated cooling fins for additional heat dissipation and a silver anodized finish for long-term corrosion resistance.

• Direct replacement for the factory thermal bypass valve
• CNC-machined 6061 aluminum construction
• Eliminates failure-prone internal thermostat for constant fluid flow
• Integrated cooling fins for increased surface area and heat dissipation
• Durable silver anodized finish
• Estimated installation time: Less than 1 hour
• Manufacturer Part Number: MMTC-RAM-TBVFF

Fits 1994-2002 Dodge Ram 2500 and 3500 (5.9L).

Heat is the primary enemy of any heavy-duty transmission, especially in Cummins-powered trucks used for towing, hauling, or high-performance driving. The Mishimoto direct-fit transmission cooler is engineered to significantly lower temperatures for your 2nd Gen Ram, utilizing a robust tube-and-fin core designed for maximum heat dissipation and reliability.

Compared to the stock unit, this cooler provides a massive 116% increase in core volume, a 141% increase in fluid capacity, and 134% more fin surface area. One common frustration with the 1994-2002 Ram is the factory quick-disconnect fittings, which often seize over time. To simplify installation, Mishimoto includes two CNC-machined, stainless steel hose barb fittings and a length of transmission fluid hose, allowing you to bypass worn factory connectors and secure the stock soft-line directly to the cooler.

• Direct-fit for 1994-2002 Dodge Ram 5.9L Cummins
• 116% increase in core volume over stock
• 141% increase in fluid capacity
• 134% increase in fin surface area
• Includes two CNC-machined stainless steel hose barb fittings
• Includes high-quality transmission fluid hose

Fits 2025-2026 Ram 1500 (3.0L).

Protect your drivetrain from heat-induced wear with the Mishimoto Direct-Fit Transmission Cooler, engineered specifically for the 2025-2026 Ram 1500 with the 3.0L Hurricane engine. Whether you are towing heavy trailers, hauling work equipment, or navigating off-road terrain, maintaining optimal fluid temperatures is critical for transmission longevity. This cooler works alongside the factory system to provide a massive 60% increase in core volume and 25% greater fluid capacity compared to stock.

The high-efficiency tube-and-fin core maximizes heat transfer, ensuring your transmission remains within its ideal operating range even under high-load conditions. Installation is designed for the home mechanic: the kit includes quick-disconnect fittings and a removable mounting bracket to simplify hard-line attachment. No front grille removal is required for the install. Finished in a durable powder coating for superior corrosion resistance, this cooler is built to handle the rigors of the road and is backed by the Mishimoto Lifetime Warranty.

Fits 2019-2025 Ram 2500 and 3500 (6.7L Cummins).

Heat is the primary cause of transmission failure, especially when your 2019-2025 Ram is used for heavy towing, fleet service, or performance applications. The Mishimoto direct-fit transmission cooler (MMTC-RAM-19) is engineered to combat thermal stress by significantly increasing cooling capacity. Featuring a massive 64% thicker core than the factory unit, this cooler adds three additional rows of fins to maximize heat dissipation.

The tube-and-fin core is designed with internal fins (turbulators) that increase the surface area of the fluid-to-wall contact, ensuring more efficient heat transfer while reducing restriction. This design ensures that even under heavy load, your transmission fluid temperatures remain within safe operating ranges. Installation is straightforward; the cooler features bolt-on mounting tabs that allow it to be installed without removing the radiator or A/C condenser, and no cutting or modifications are required.

• 64% thicker core with 3 additional rows for superior cooling efficiency
• High-efficiency internal fins maximize fluid contact and heat transfer
• Tube-and-fin construction optimizes airflow while reducing fluid restriction
• Direct-fit design requires no cutting or modification to the vehicle
• Includes all necessary hardware for a clean, professional installation
• Manufacturer Part Number: MMTC-RAM-19
