ATS Thermal Bypass Valve Upgrade with Billet Filter
Fitment: 2019-Current Ram 6.7L Cummins with 68RFE or Aisin AS69RC Transmissions, and Dodge HEMI with 545RFE, 65RFE, or 66RFE Transmissions


This is a must for any truck that has a 68-RFE or Aisin AS69RC transmission in it. Dodge decided 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 percent of the trans cooler flow is forced through the trans cooler. In every case this substantially reduces transmission temperatures.

Includes:
  • ATS Thermal Bypass
  • Cooler Block Clamp Plate
  • Billet Filter Coupler

Worth every penny!

by Cody

Install takes no time at all.
I had to move my camper right after putting it on (which weighs around 16,000 pounds), the transmission stayed much cooler than it would have with the factory bypass. I’ll replace the coupler next time I change fluid and filters, but anything beats the stock plastic one. This is the best kind of mod there is, inexpensive, easy to do, and works!

55 degrees cooler

by Dan

2022 Ram 2500 6.7 under normal everyday driving (not towing) the transmission temp would run 178 degrees. Installed the thermal Bypass and now 123 degrees is what I am seeing now. Great improvement.

Significant emperature drop after install

by Craig Dunning

2020 Ram 2500 6.7 Cummins. Prior to Thermal Bypass install, always ran 165-170 F degrees around town. After install and hauling 10k for 500 miles including hills, never exceeded 143 F.
