Thermal bypass for 2018 Chevy Silverado 6L80

This product is absolutely amazing, my truck temperature doesn’t exceed 170’s after an hour on the road. Very pleased with it.

Easy and simple install, i installed it while i changed the tansmission filter and fluid, dropped the temp down 25 degrees so far, it isnt hot outside yet and i havent been towing but i have feeling it will do just fine keeping tbe temp down. Amsoil ATF and this is the way to go!
