Product Details

Product Name: Thermal Bypass Valve Upgrade with Billet Filter Coupler
Manufacturer: ATS
Manufacturer Part #: 3100052464
Thoroughbred Diesel Part #: ATS3100052464
Fitment Notes: 2019-24 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
  • ATS 68RFE Billet Aluminum Filter Coupler

Submit a question

  • I purchased this for my 2020 Ram 2500 Laramie. The OEM has a bracket to stabilize it. My new ATS bypass doesn't a bracket or stabilize it. Will this be an issue?

    Oscar Vera | 10/26/2025

    We have not heard of any issues.

  • Will this work on a 2024 6.7?

    Billy | 9/20/2024

    Fitment to a 2022 at this time

  • Will this impact the factory warranty?

    Gary Cuedek | 7/8/2024

    It should not, but that will be up to your warranty provider.

  • do you have to by the 2 screw in fitting separately ? or do you not need them forthe 68rfe?

    junior cardiel | 11/18/2023

    ATS 68RFE Billet Aluminum Filter Coupler is designed to replace the plastic factory filter adapter.
