Revmax Transmission Cooler Thermostatic Bypass Upgrade Compatible with 2017-2019 Chevy/GMC 2500HD 3500HD 6.6 L5P Duramax Diesel Allison 1000
  • Increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part.
  • There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction.
  • Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later; our bypass allows your cooler to immediately begin cooling your transmission and not waiting for it to get hot, just to try to cool it later.
  • You cannot properly flush your cooler lines without the aid of a hot flush machine that can get hot enough to open the bypass valve up. With our bypass upgrade you can use room temperature fluid to clean out your cooler anytime you wish without any special tools!
  • 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.
