Transmission Cooler/Cooler lines

I try not to run the cooler in the radiator, I understand about heat management, but a friend of mine had the radiator cooler go bad. So the atf and antifreeze mixed. I have run the Moroso stick on heat pads on the trans pan before. I run the large plate cooler on everything I can. They make 1/2 pipe to # 6 an fittings, and 1/8 pipe to # 6 an fittings.
