      2017 Silverado Transmission cooler flow system

      Posted by Shawn Kramer on Sep 18th 2020

      I put this transmission cooler slow system on my truck and my average temperature of my transmission before installing this part was 190 degrees, after I installed the transmission cooler flow system my temperature stays around 155 degrees. All city driving. Great quality parts and outstanding execution of the product and how it performs!!!!
