Default A4 trans line leak, help?

I have a leak at one of the two A4 trans line connectors located at the back of the engine block. I've cleaned it twice but can't seem to catch which line it leaking, as it sprays fluid a fair bit over everything. Any tips on how to determine which line it is? I hate to undo / redo all four connections, as flare lines can be a pain in my experience.

Any tips out there, or should I just undo all of it, clean all the threads and seats well, and put it back together again?

Have a lift avail You could just watch while it's runnig.
I would just put a tuing wrench on all 4 flare nuts and crank them down.
Hopefully not a cracked line.

I've tried tightening them down before without any luck, that's why I was thinking about seeing if they needed to be reseated maybe.

I have it up on stands and will be changing out the trans filter / fluid today, so I will watch itclosely then.

I really hope it's not a cracked line either

Try putting some anti-seize on the flare nut threads. It might help to allow the flared connections to seat more tightly.

A dab of anti-seize on the tubing flares, also may help to create a better fluid seal at the connection.
