On My 2001 GP, the trans lines are both located on the passenger side of the radiator with the bottom metal line being the inlet line and the top line coming out of the radiator being the return line to the tranny. Just cut both lines with a tube cutter where they work their way over to the radiator to inlet/outlet side about half way across the bottom of the radiator and then use the rubber hose provided, which in my case, the Long Double Stack cooler provided to by pass the 2 OEM metal lines into and out of the radiator to go to the cooler in the grill. I don't know the diameter of the metal cooler lines but used the plastic caps that came with the Long cooler to cover the inlet/outlet ports of the cooler in shipping to cover the cut metal tranny lines into and out of the cooler that were no longer being used. Hope that helps!
