Transmission cooling lines...

I have a 84 x-body car with a 2.5L 4cyl 151 R "iron duke motor"...

There is 2 lines on the front of my AT 125C automatic transaxle..

they go to the radiator... I disconnected them and like a dumb *ss mixed them up.. One line goes to the top of the radiator and one to the bottom..

How do I know how they go?

I bet it is an Oldsmobile Omega. The answer was provided at this post at the Oldsmobile forum:
