Transmission line leak
04 4.7L HO with 545RFE.

I have a leak where the transmission line runs into the radiator. Basically its leaking at the coupling. It would be a easier fix if the lower radiator hose wasn't there. Is there a gasket in that coupling that could be the issue? Also if someone knows if I disconnect it to either replace or put thread tape on there, how much fluid will I be wearing.

You could try loosen it and fasten it again, that will sometimes help. There is no gasket or seal, just metal to metal contact. I did remove my lines when replacing the radiator and didnīt see much fluid coming out.

Cool. Instead of tape, I'll probably use Hi temp RTF on the threads.

Reached up with a 22mm wrench and it was a little loose. Now good to roll.
