I have a 1991 Oldsmobile Delta 88 Royale Brougham 3.8L 231cid (C) with a ME9 4 speed automatic transmission. When I was replacing the transmission lines from the trans to the radiator, I somehow got them mixed up. I need to know which is the return line and which is the pressure/feed line on the radiator. Which one goes to the top fitting and which to the bottom. Can anyone help with this?? THANKS!!!
