Dfuser 1002399-1 68RFE Transmission Thermal Bypass Valve Upgrade

This is a MUST for any truck that has a 68-RFE transmission or the Dodge HEMI with 545RFE, 65RFE, or 66RFE Transmissions in it. Dodge decides to incorporate a transmission cooler bypass valve into the cooling system of the 68-RFE and Aisin AS69RC that bypasses the transmission cooler during cold operation. The intent is to force the transmission to warm up faster, the reality is this bypass valve leaks and sticks in the bypass position in almost every case causing the transmission cooler flow to bypass the trans cooler essentially eliminating the trans cooler from the circuit. This causes a severe damage to the transmission over time. The dfuser cooler block replaces the faulty design eliminating the bypass valve and ensures 100% of the trans cooler flow is forced through the trans cooler.  Features: Made of 6061 Aluminum Direct replacement Reduced transmission temperatures Thermal Fins for optimal cooling Replaces OEM PN 68186711AA, 68186711AB, 68RFE, AS69RC, 545RFE, 65RFE, 66RFE Replacement for 2013-2018 Dodge Ram 6.7L Cummins Diesel Warranty for 12 Months Parts List: (1) Thermal Bypass Valve (2) Pre-Installed O-rings Vehicle Applications: 2013-2018 Dodge Cummins 6.7L Diesel with 68RFE or Aisin AS69RC Transmission Customer Testimonials: "A total big difference in temperature" "Easy to install as well" More Information: Install Guide
