Patman1, I am so very sorry that I didn't revisit this thread. A year, plus, is inexcusable, and I apologize, but I still could use the help. I didn't receive a notification that a reply had been posted.
When I disconnect the lower transmission hose from the radiator connection, a small amount comes out. (I work on a slight incline in my driveway, and go down where the radiator shroud would be. I remove the shroud to work on that line.) I'd estimate it to be a couple of cups, 6 - 8 oz.
My solution, in Sept 2017, was to slather the back of the fitting/collar-nut, and the metal of the hose with Black Ultra RTF sealant. It created a seal from where the drip was occurring. It stopped the leak for about a year.
I noticed the drip occurring again, last week (Dec 2018). I removed the shroud, cleaned old Black Ultra RTF sealant off the fitting, and loosened the fitting/collar-nut. I pulled off the nut/collar, and waited for as much ATF to drain out as I could. It looked like some of the end of the radiator fitting was crushed, like a cross-threading had occurred. I was told, once to put on Teflon Tape, as used in plumbing applications to help seal it. I tried to apply the tape, but had difficulties, yet ended up with at least one wrapping of it along the radiator connection. I reattached the nut/collar, paying attention to how 'direct/straight' the fitting was. I tightened it as tight as I could, and again, slathered the nut/collar end-closest-to-the-transmission with the Black Ultra RTF. It has, still, a small drip, but not massive, and I don't see it on my driveway, yet, but have seen some along the bottom rubber radiator hose.
Is there supposed to be a rubber seal/o-ring at the back of that nut/collar to help seal that?
Thank you for your help, Patman1.
