Explanation? I am not doubting your word but the top of the radiator is hotter than the lower. Why send hot fluid in the cooler section and take it out at the hotter section?
What about horizontal coolers?
Now, I know the OE's use hot transmission fluid to heat the radiator quicker to get into warm closed loop faster but that is an emission deal not transmission life consideration.
