ATS Billet Thermal Bypass Block Upgrade 10-12 Ram 6.7L CumminsDo you want to protect your transmission and keep temps under control when towing or pushing your truck hard? If you have a Max Tow Package or Dual Transmission Oil Cooler installed you need to fix a factory failure point that can cause hot transmission fluid to miss the cooler and go back onto your already hot transmission. ATS's Thermal Bypass Valve Block Upgrade for 6. 7L Cummins is designed to eliminate this weak point by using a solid flow billet

Do you want to protect your transmission and keep temps under control when towing or pushing your truck hard? If you have a Max Tow Package or Dual Transmission Oil Cooler installed you need to fix a factory failure point that can cause hot transmission fluid to miss the cooler and go back onto your already hot transmission. ATS's Thermal Bypass Valve Block Upgrade for 6.7L Cummins is designed to eliminate this weak point by using a solid-flow billet block that removes that issue.

Fix a Common 6.7 Cummins Transmission Problem

The factory thermal bypass valve found in select 2010-2012 Ram 2500, 3500, 4500, and 5500 trucks is known to fail when the internal thermostat sticks closed. When this happens, transmission fluid bypasses the cooler entirely, causing dangerously high temps that can lead to clutch damage or complete transmission failure.

The ATS Thermal Bypass Valve Upgrade eliminates this issue by removing the restrictive thermostat and allowing constant fluid flow through your cooling system.

Performance Gains

By allowing unrestricted transmission fluid flow, this upgrade can significantly lower operating temperatures:

• Highway Driving: Reduced temps by up to 40–60°F
• Moderate Towing: Reduced temps by 30–40°F
• Heavy Towing: Reduced temps by 25–30°F

Constructed with high-quality materials designed to handle heat, pressure, and constant fluid movement, this upgrade is built to withstand the demands of towing, performance use, and heavy-duty driving. The direct-fit design allows for straightforward installation using factory mounting locations, while the robust construction ensures consistent performance without degradation over time. This makes it a reliable, long-term solution for improving transmission cooling efficiency and preventing heat-related failures in your Cummins.
