Trans. fluid leaking from radiator fitting

[PashRoot]

Doing my monthly routine check on fluid levels and such I noticed I was leaking AT fluid from the radiator. At first I thought my radiator cap went bad again but taking some pictures from below revealed otherwise.

Do I need to replace an O-ring or just tighten the fitting? Can't do anything right now.. way too hot under there.

And for those that read my previous thread, yes.. it was the bearings. No more random triggering ABS or grinding noises.

Try tightening the fittings. Clean off the lower hose, the ATF will degrade the hose quickly.

I'm thinking it may have been cross-threaded as I couldn't get it any tighter after reseating the fitting. Either way it's not leaking anymore from what I can tell.

I cleaned off the lower hose right away.
