I have considered both those options because that would be so much more easy. But the only problem i have with them is that eventually those lines that are rubber will crack or if they are rubbing on anything its going to rub a hole right in them. Also the rubber line doesnt disperse the heat either like the steel line does. That steel line almost acts as radiator itself and kinda somewhat pre cools the oil before it even reaches the radiator(thus resulting in lower tranny oil temps then if i used rubber hose) But thats just my thoughts, i may be totally off base i dono thats why i came here for some help
