Tranny cooling lines into radiator- supply/return?

If I am looking at a radiator straight on from the back, there is the auto tranny cooling reservoir on the RH side of the radiator; There is a cooling line inlet towards the top of the tank, and an inlet towards the bottom of the tank.

Which is feed and which is return? Thanks! I am hooking up an auto tranny cooler.

The line on the bottom of radiator is coming from tranny. The top fitting goes back to the tranny.

If you are putting two in series it sure matters... I am using the stock reservoir in series with the new cooler.
