ATS Thermal Bypass Valve Up-Grade Fits 2013-2018 6.7L Cummins W/ Billet Filter Coupler

The ATS Cooler Block is a MUST for a Dodge Ram HD that has a 68RFE or Aisin AS69RC automatic transmission in it. The ATS cooler block replaces the faulty design of the stock Thermal Bypass Valve and ensures 100% of the trans cooler flow is forced through the trans cooler. In every case this substantially reduces transmission temperatures. Also fits the 66RFE.

68-RFE Trans Cooler Bypass Block, for Cummins 68-RFE or Aisin AS69RC Transmissions and the Dodge HEMI with 545RFE, 65RFE, or 66RFE Transmissions. This is a MUST for any truck that has a 68-RFE or Aisin AS69RC transmission or the Dodge HEMI with 545RFE, 65RFE, or 66RFE Transmissions in it. Dodge decides to incorporate a transmission cooler by pass 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 ATS cooler block replaces the faulty design eliminating the bypass valve and ensures 100% of the trans cooler flow is forced through the trans cooler. In every case this substantially reduces transmission temperatures.

Billet Filter Adapter Included (3010212326)
Another part that can be damaged by the heat allowed to pass through the factory bypass valve is the factory plastic filter coupler. We manufacture this Billet Filter Coupler so that the filter has a solid mounting point which won’t be compromised by higher temperatures or over-tightening.
