trans cooler lines?
 

anyone know which trans cooler line at the rad is the outlet from the transmission? I'm thinking its the lower one.
I am going to do a trans fluid exchange and want to disconnect one line at the rad that fluid will flow out of. I will put a hose on the line and direct the fluid into a waste container. If I disconnect the wrong one, fluid from the rad will go all over.
