Mishimoto 2013-2018 Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit

Protect the 68RFE or Aisin AS69RC transmission in your 2013-2018 Dodge Ram 2500 or 3500 with 6.7L Cummins using the Mishimoto Thermal Bypass Valve Kit. This direct replacement prevents overheating by allowing fluid to reach the cooler sooner than stock. CNC-machined aluminum construction delivers reliable performance under high torque loads up to 930 lb-ft.

Key Features

  • CNC-Machined Aluminum Body: Black anodized finish resists corrosion and adds cooling fins for extra heat dissipation beyond stock design
  • Replaceable Thermostat: Opens 10°F earlier than OEM for quicker fluid flow to cooler without overcooling in normal conditions
  • Swappable Bypass Option: Enables full flow to transmission cooler regardless of temperature, ideal for hot climates and changes with a wrench
  • Improved Flow Rate: Outflows stock valve in both standard and bypass modes for more effective temperature control
  • Complete Kit: Includes valve, thermostat, O-ring, and hardware for seamless installation with Mishimoto Lifetime Guarantee

Product Notes

  • Direct bolt-on replacement for stock in-line thermal bypass valve, no vehicle modifications required
  • Designed for diesel trucks generating high heat, maintains optimal fluid temps for transmission longevity
  • Securely packaged for damage-free delivery

Installation Notes

  • Professional installation recommended.
  • Bolt-on design takes under 1 hour with basic tools, no cutting or drilling needed
  • Reuses stock mounting location and hardware, fits both 68RFE and Aisin AS69RC transmissions
