thanks memike. my brother was saying to have it like i got it pictured, because although heat does travel up, so does air bubbles, and to have fluid flow in the bottom and out the top would also alow air bubbles to flow out.....both valid points i would think.. i dont question my brother and i value his opinion, just wondering what some of you guys think and which way yall run urs.. :)

I can't imagine it makes any diff. at all. The ATF is under pressure so there shouldn't be air bubbles in it and it flows so fast heat isn't going to have much of a chance to rise.

Fishy is right. IMO, hot up top, cool return down low.

Think not about air bubbles, there being forced out. Perhaps, someone around you has air bubbles in there head and to much time on there hands. LOL
