Product Name: RevMax Allison 1000 L5P Transmission Cooler Thermostatic Bypass Upgrade - 2017-2019 GM Duramax L5P Manufacturer: RevMax Manufacturer Part #: A1000-934 Thoroughbred Diesel Part #: REVA1000-934 Fitment Notes: 2017-2019 GM Duramax L5P
All 2017+ L5P Duramax equipped GM/Chevy trucks have always been known to run hotter than then their early predecessors. There also have been numerous melted down transmissions due to the bypass valve sticking in the cold closed position. Lastly, the thermal bypass has a large restriction in it which massively reduces cooler flow! The completely re-engineered, Billet 6061 Aluminum RevMax Cooler Thermostatic Bypass Upgrade module, completely fixes all of these complaints. Utilizing our ZeroStat Technology, We completely removed the orifice restriction for full cooler flow all the time. This equates to lower operating temperatures and longer transmission life. Simply bolt in our block and you will see up to a 50-degree change. Our billet Cooler Thermostatic Bypass Upgrade completely eliminates the thermal bypass valve and this elimination gives you three major advantages.
The RevMax Allison 1000 L5P Transmission Cooler Thermostatic Bypass Upgrade is a direct bolt-in replacement. No lines are cut, nothing is altered. Simply disconnect your old lines and install them into our new bypass.
