Default ATF leak at radiator

I got a 1994 dakota and so far the only problem I've found is that when parking after driving it leaks a few drops of transmission fluid. Last night I readjusted and tightened the hoses that lead from the transmission to the radiator, but this morning it still appears to be leaking. The leak originally looked like it was coming from that bolt/nipple thing on the radiator. Is there an o-ring gasket in there that could be bad? I've already tried tightening it, but don't want to strip the threads by making it too tight.

These hoses get crappy over time. Probably just need new hoses. I had that problem on my parents town and country. The hose developed a lead before the clamp. Cranking on the clamp had no effect on the leak.

Replace the hoses. There is no o-ring on the nipple, it's a pressure type fitting, similar to a metal brake line.

I replaced the hoses and clamps with brand new lines. Still a small drip when I park from the passenger's side. Any other ideas? Could it be the metal hose fitting in the radiator?

It doesn't look like it. But I *THINK* I found the problem. The drops I've been seeing appear to be coming from the crossmember where some ATF has pooled when I was draining some of the fluid. So it's still dripping. I was going to get the underside power washed, but it's going to snow tomorrow, so I'm just getting a full service wash later in the week.

Well after you power wash it, and let it dry once the cocaine stops falling. Put a cardboard box under the area where it was and check it in the morning, no drips your good, you got drips well I would really give it an eye over.
