1971 radiator question

[dtkarst]

I’m just about to install my rebuilt transmission in the 71 c10 and had a couple questions. It has an external cooler for the transmission in front of the radiator out on at one point for hauling a slide in camper, so I was told. Well I don’t intend on pulling or hauling anything heavy with it anymore so do any of you think it’s okay to hook up the transmission the way it was originally into the radiator? It doesn’t appear to have any plugs in the ports for the lines from the transmission though. It’s either hook them up the original way or Use the external. I will probably change the external if I go that route since everything else would be new
