Well my truck didn't come with one so here I am trying to put an aftermarket one on the truck. I'm leaning towards a cooler with a fan. Go big or go home right? My questions are mostly gonna be about the lines. How in the world would I even go about using the existing lines on the truck? Do I splice into them? And as far as mounting the trans cooler would it be ok if I just use those plastic clips that go through the radiator?
