Thanks 14burrito. I am in Phoenix, so yeah, the temps are tougher to deal with. I saw somewhere where someone removed some of the slats in the shutter, opening about half of it. If I were to do something like that, would I still need/want an extra cooler? so many things to consider. Lol. thanks again.

I read through this thread and learned a lot. But I have a couple of questions. I did the pill flip on my 2017 Suburban 6l80. I did it because I tow a 6500lb travel trailer and the trans temps were a shy over 200 flat towing and climbed to 210-215 when towing up a grade. With the swap, towing on a level plane results in trans temp of 175 and when going up a grade 195. I’d like to get the temps down a little more so I was considering adding a Tru-Cool 30k trans cooler. Btw, currently the fluid goes through the radiator tank and then the condenser cooler. However, my Suburban has the shutters in front of the radiator that I understand close at certain times. Would this negate the benefit of the added cooler? Appreciate any thoughts or experiences. Thanks.
