4l60e Cooler line flow direction

Just wanting to make sure I have the routing correct.

Trans is a 4l60e, radiator is a stock thirdgen replacement. On the trans the top fitting is the return, connecting to the lower fitting on the radiator. And the bottom fitting on the trans is the feed, connecting to the top fitting on the radiator.
