I've searched and searched and can not find my answer so here goes.

I'm trying to buy the replacement trans cooler hose from rockauto.com. But i can not seem to find the right on. I have an automatic with the 4.0l in it. Its the trans line on the top of the radiator with the big threaded nut. It asks if the line goes to the rear or front of the trans. I can't look cuz my jeep is currently about 100 miles away at my mothers house. Any help would be greatly appreciated!!!
