Get Cooler With XDP

May 2021 Products Web Exclusive

Replace the problematic factory thermal bypass valve in your 2013-2018 Dodge Ram 6.7L Cummins before it causes catastrophic failure with the XDP Transmission Cooler Thermal Bypass Valve (TBV) Upgrade XD343. XDP’s Thermal Bypass Valve Upgrade utilizes an unrestricted straight through design, eliminating the recirculation aspect of the factory TBV. No more having to worry about when the factory part will fail you. By removing the passageway that returns hot fluid back to the transmission, fluid restriction is reduced, lowering overall transmission temperatures.


  • Eliminates Hot Fluid Recirculation
  • No Modification Needed For Installation
  • Fits 68RFE & Aisin AS69RC Transmissions
