Simple to install and temps are down
This is a well made product that anyone can install with ease. My 2015 Silverado transmissions temps went from 190-200 to 150-160. I have had no issues 100% recommend for anyone if your worried about temperatures and want to prolong the life of your transmission.

2018 F150 pan replacement
Great product, took it to the dealer to get it installed, it uses the OEM pan bolts, just get a replacement gasket, it was done in 4 hours.

Cool Runnings
If you have a GMC vehicle, you need this cooler. Works as advertised, temps have not gotten above 137°. It's winter right now so we'll see how the temps run in the summer.
