ATS Diesel 310-005-2392 Thermal Bypass Valve Upgrade 68RFE for 2013-2018 Ram 6.7

Vehicle Fitment

• 2013-2018 Ram 2500 (6.7L I6 Cummins Diesel, 68RFE Automatic Transmission)
• 2013-2018 Ram 3500 (6.7L I6 Cummins Diesel, 68RFE Automatic Transmission)
• 2013-2018 Ram 2500 (6.7L I6 Cummins Diesel, Aisin AS69RC Automatic Transmission)
• 2013-2018 Ram 3500 (6.7L I6 Cummins Diesel, Aisin AS69RC Automatic Transmission)

Fitment Notes

• Compatible with both 68RFE and Aisin AS69RC transmissions - covers all automatic transmission options for 2013-2018 Ram 6.7L Cummins
• Also fits 66RFE-equipped Ram trucks
• Direct bolt-on replacement - mounts in place of the factory bypass valve assembly on the passenger side of the transmission
• A small amount of transmission fluid loss is expected during installation - use a drain pan

Features

• Eliminates the factory thermal bypass valve, forcing 100% of transmission cooler flow through the trans cooler at all times
• Solves the factory bypass valve's tendency to leak and stick in the bypass position - a known cause of transmission overheating and failure
• Substantially reduces transmission operating temperatures in every application
• Gold anodized aluminum cooler bypass block resists corrosion and heat degradation
• Includes billet aluminum filter coupler - replaces the OEM plastic coupler that is prone to damage from heat and over-tightening
• Precision-machined adapter fittings ensure a leak-free, secure connection to factory cooler lines
• Direct bolt-on installation - no modification to factory lines required

Specifications

• Material: Gold anodized aluminum (bypass block); billet aluminum (filter coupler)
• Compatible Transmissions: 68RFE, Aisin AS69RC, 66RFE
• Cooler Flow: Forces 100% of flow through trans cooler (bypass eliminated)
• Shipping Weight: 2 lbs
• Warranty: Lifetime / Unlimited Miles

Included Components

• 1x Gold Anodized Cooler Bypass Block (Dodge 68RFE 2013-2018)
• 2x ATS Adapter Fitting Assembly (quick-release cooler line fittings)

Product Description

The ATS Diesel 310-005-2392 Thermal Bypass Valve Upgrade is the definitive fix for the factory transmission cooler bypass problem on 2013-2018 Ram 2500/3500 trucks with the 68RFE or Aisin AS69RC automatic transmission. The OEM thermal bypass valve was designed to reroute transmission fluid around the cooler during cold starts for faster warm-up - but in almost every real-world case, it sticks in the bypass position, eliminating the trans cooler from the circuit entirely and causing sustained overheating that destroys the transmission over time.

The ATS upgrade replaces the faulty factory valve with a solid aluminum bypass block that forces 100% of cooler flow through the trans cooler at all times. The kit also includes a billet aluminum filter coupler to replace the heat-vulnerable OEM plastic unit. A direct bolt-on installation with no line modifications required, this is one of the highest-value preventive maintenance upgrades available for any 2013-2018 Ram diesel owner. Backed by a Lifetime / Unlimited Miles warranty.
