The return line (transmission inlet) is the upper hose and the outlet is the lower hose. For your transmission cooler, I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503. If you have the 5.9L I-6 turbo diesel, then you don't need adapters. If you have the 5.9L gasoline V-8, then you will need adapter # D13034 or # HH41413. You will want # D13034 if vehicle equipped with 9/16"-24 thread SAE fittings. You will want # HH41412 for 5/8"-18 S.A.E. 45º fittings.
