You guys are confusing issues here...
First of all heat DOES NOT RISE. There is nothing special in "heat" that makes it defy gravity.
The reason a hot air baloon rises is because when the air is heated, it expands and becomes less dense. The lower density air "floats" on the high density air. So the hot air goes "up".
Same thing happens in fluids. The hot fluid expands and is less dense, and therefore rises.
Heat through a solid body does not cause any change in density. Solid fins on a trans cooler do not change position. Nothing is "flowing" like happens in air or fluid.
The reason that radiators flow trans fluid from bottom is because of a principal called counter current heat exchange. This is because the hottest water can cool the very hot trans fluid effectively. The trans fluid can only be as cool as the last point of coolant temperature that it exits. It's more effective if it exits at the lower point where it's coldest.
The question at hand about trans fluid through a normal (non-coolant heater exhange like a radiator) does not apply to "heat rises" or "the OEM did it like this."
The direction on a finned fluid to air cooler does not matter at all.
Call it what ever you want... hot air goes UP and yes I know about the density

And here is another twist ------ I have an external trans cooler and both hookups are facing down Should the front hose go to the left down facing connection or the right down facing connection Just want to get it right.................. Russ

Here is where you MUST take a scientific approach. I'd suggest either a coin toss , or eeenie ,meenie , miney , moe.......... These empirical methods will never let you down.

I have seen them laying flat on the back of dragsters with the inlet/outlet pointing toward the front also, just like I said before,,,it don't matter, as long as you get air flow across it,,we could sit here and debate this till the cow's come home.
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
