1978 f150 single cab short bed trans oil leak at the fitting for the radiator (which is brand new) could the fitting be bad?

 

Have you checked and made sure it's tight?

 

The fitting or the hose clamp over the fitting?

 

You said leak at the fitting. Check and make sure it's tight since your radiator was obviously recently replaced. May as well check that hose clamp as well too.

 

Ok ill check but i was saying i didnt know of the leak came from fitting or the little metal piece that goes around the hose to the fitting that tightens with a flat head. But ill check the fitting when the sun comes up its only 5:40 am right now
