It comes out of your trans and runs to the top drivers side of the rad then out the bottom to your external cooler and back to the trans.
A lot of guys put the T in closest to the trans or under the rad. I added mine just before it goes into the top of the rad. I wanted to keep it out of the weather (read road salt). I am guessing that the fluid gets there fast enough to only lose a degree or two.
