Tranny cooler installation
 

So I picked up a tranny cooler, and im trying to install it, but idk wat lined are wich, I want to go from radiator to cooler, to tranny. Any help would be great

according to this the lower is the return line one word of advise mount it in front of the passenger side fan so air is being pulled thru it even at idlehttp://www.jeepsunlimited.com/forums...d.php?t=354750

So are these the 2 lines? The lower one in the pic is return and upper is outgoing? Like the skinny line u see infrount is out going, and the skinny line underneath that is return?

Heres a pic of the tranny cooler

ive found to different write up one shows upper one show lower take the top line off the rad have sone one start the xj just for a second see where the fluid come from if it come out of the line use the lower if it comes out the rad use the upper
