Help Needed - 78 Turbo 400 Transmission Cooler Lines

[JAG811]

Ok so two other buddies helped pull out the auto after they were giving me saying I never let anyone one else touch anything I'm working on .... Because - Know I don't know which oil cooler line goes to which auto line on the GM Turbo 400 ???
If anyone knows please help.
There's two steel fittings out of the GM Turbo 400 . I would assume the top is the gravity fed return and the bottom would be the pumped outlet ???
There is a top and bottom fitting on the cooler.
I would assume the auto would pump oil into bottom of the cooler, be forced to the top of the cooler and then return to the top fitting for the GM Turbo 400 ..... But I've been wrong many times

Can anyone help ?

AWESOME !! Ok so that was as I assumed. So if the cooler is just a top and bottom feed, as am I correct in assuming the lower feed/out pipe on the GM Turbo 400 would lead to the bottom of the cooler, pushing it up and threw and then gravity feeding down back to the GM Turbo 400 ???
