Installing an aux transmission cooler and I’m trying to find out which line goes back into the transmission with cooled ATF. 2005 SE

Forgot to ask, are aux transmission coolers directional? Could I place it upside down so I won’t have to use as much hosing or should it always be up with the lines coming out from the top.
