find out which line from whatever trans you have is the feed port to radiator is. That line would be the shorter one as the return one extends up to the top fitting of radiator

 

I realized the one that went into the lower most radiator fitting, still had its crimped on flare fitting.
So that must be the feed line then?
From there it came out the top radiator fitting and over to the cooler, then out the cooler and back to the transmission.

I should have took pictures before disassembly.
I can't put it back like it was exactly because this radiator is a different size and there seems to be less room to play with. I want to make sure the cooler is placed where the wind coming in will go right across it. Over to the side, its behind the new core support which will impede the wind coming in.
