Back when we had a V8 Trailblazer EXT I added a trans cooler and ran it from the radiator out to the new cooler and back to the trans. Kinda defeats having a cooler if the fluid gets cooled then run thru a 200 degree radiator on the way back to the trans.
Cooler worked great and in upper 90 Texas heat the trans never went over 205. Coolant temp pulling hills though would spike to 240ish which I never liked. The 5.3 and 4l60 just didn't like towing a 5800lb trailer.
Replaced it with a Sequoia 6 months after getting the trailer.
