Lower transmission line leak at radiator bolt: trick to tighten and seal?

I replaced repaired radiator into 1998 C280. Tightened upper Transmission line Banjo Bolt with no issues. No leaking under pressure. Since the line going into the lower radiator transmission cooler port is a flared fitting, I've tightened it up as tight as it can go, but I'm still experiencing a tiny drip, when she's under pressure. Is there a trick to tightening it to prevent a leakage?

I'd say to make sure to get the mating surfaces as clean as possible. Just a question, does all the transmission fluid come pouring out if the lines are disconnected (car turned off), or is there only minimal fluid loss (whatever happens to be in the lines)?
