Mishimoto MMTC-RAM2-TBV Transmission Oil Cooler Thermal Bypass Valve Kit for RAM 6.7L Cummins

The Mishimoto MMTC-RAM2-TBV Transmission Thermal Bypass Valve Kit is an upgraded replacement for the failure-prone stock thermal bypass valve found in 2019+ RAM 6.7L Cummins trucks equipped with 68RFE or AS69RC transmissions. The stock valve's thermostat is prone to failure, which can block transmission fluid from reaching the cooler entirely, leading to overheating and potential transmission damage.

Key Features:

• CNC-machined billet aluminum construction with durable black anodized finish
• Increased fluid flow over stock bypass valve for improved cooling efficiency
• Includes serviceable 160°F thermostat that opens approximately 10°F earlier than stock
• Includes full-flow bypass insert for constant cooling in hot climates or heavy towing applications
• Integrated cooling fins machined into valve body for additional heat dissipation
• Direct-fit design installs in under 1 hour
• Easy switching between thermostat-controlled and full-flow modes with basic hand tools

This kit provides superior cooling performance compared to the factory valve in both thermostat-controlled and full-flow configurations. The replaceable thermostat allows fluid to reach the cooler sooner without overcooling, while the included bypass option provides maximum cooling for demanding conditions. Backed by Mishimoto's Lifetime Warranty.

Kit Includes: Thermal bypass valve assembly, thermostat insert, full-flow bypass insert, O-rings, Dowty seals, and mounting hardware.
