You make good sense, heat rises so just like a radiator bring the hot to the top and let the cool leave at the bottom JMO.
It most likely don't matter on a trans cooler, nice install
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.. :)
