Review on 🔧 Enhanced Performance Hyper-Cool Remote Engine/Transmission Cooler by Derale - 15960 by Darin Marshall

Monster Transmission Cooler. I removed the trash cooler that the mechanic installed on my 2008 Silverado and replaced it with this Derale 15960. My truck ran smoothly from 200 to 225 degrees with only occasional trips into the 140-165 range with no fan! The transmission cooler was very easy to install, at least for me, because I simply removed the old cooler and rerouted the hoses. I connected the fan to the fog lights instead of the included sensor. In my case I can just turn on the fog lights manually to turn on the fan. I had to change the direction of the fan, but that was quickly fixed by swapping the ground and power wires.
