Mishimoto Full Flow Thermal Bypass Valve Kit for 2013-2018 Ram 2500/3500 (6.7L) MMTC-RAM-TBVFF

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.
