Hello guy I got 2015 Chevy Silverado 4x4 5.3L single cab short bed. I have done few mods which is (afe intake- jets throttle body - tune). usually in the weekend me and my friends go for off roading trips, and I am facing a trouble with the transmission temperature it could reach to 221F usually what I do, i open the hood and the AC for couple of minutes till it goes down. What I want to ask that I just have to delete the transmission thermostat or install transmission cooler, or the last option is to do both of them.
