About this item

  • Fitment: Our Transmission Fluid Thermal Bypass Valve is compatible with 2015-2018 Silverado/Sierra 1500 models equipped with an 8L90 transmission and 3/8" line.
  • Enhanced Cooling Performance: Upgrade your transmission with the Transmission Fluid Thermal Bypass Valve. By eliminating the restrictive factory valve, this upgrade ensures better fluid flow and keeps your transmission cooler, especially during heavy towing or stop-and-go traffic.
  • Protect Your Transmission: Say goodbye to overheating risks caused by a failing OEM valve. This bypass valve maintains steady fluid circulation, reducing wear and tear while helping your transmission last longer.
  • Built for Durability: Made from tough billet aluminum, the bypass valve is designed to withstand the test of time. Its solid construction resists mechanical failures and prevents clogs caused by debris.
  • Superior Debris Protection: Equipped with a Neodymium magnet and O-ring sealed service plug, this bypass valve captures harmful metal particles before they can damage your transmission. This added layer of protection outperforms the stock valve, giving you peace of mind on the road.

Replaced part as per manufacturer manual to fix the known issues with Chevy Silverado 2014-2019 transmission.Lasted a couple hundred feet before the o ring gave out. Definitely do not recommend, there are other manufacturers that provide the same solution.Magnet implementation was a good design intent, but caused failure modes that do not exist with OEM solution.It is easy to install and it fit with no issues. Its good value for the build, but the design flaw is a 1 star from me!

If you have a Silverado or Sierra with an 8L90 transmission, this bypass valve is a must-have upgrade. It works like a charm.
