Transmission fluid leak - Resolved

[Donf]

About 6 months after having some work done on the truck, which entailed radiator removal, I began having a leak. Nothing heavy but it's building up in the driveway and it's now officially too hot to stand over a hot, running engine and check it every 10 to 14 days and add 4 to 8 ounces of fluid.
I think I've found it - upper line where it attaches to the cooler. Obviously this isn't a "crimp issue" which seem quite common. Is it reasonable too think that I can get a pair of wrenches down there and tighten it? Isn't there an O ring inside that connector? Or should I just replace the line?
My hands are still recovering from some minor work a few months back but are working fine, if a bit weak, just don't want to get into something difficult.

Thanks.

The transmission lines are flared fittings so it shouldn’t have an o-ring. I’d clean it and try to snug it up.

Will do, Thank you

Thank you east302, as usual you were correct.
I got a wrench on the nut and was able to turn it a quarter turn with less force than
I knew I should have to exert. From there it was a bit of a chore to get a pair of wrenches on both sides and crank it down another quarter turn without putting too much stress on my fingers. (Several years ago I damaged some of the tendons between my hand and my fingers and I finally had to get a bit of surgery and then some radiation. I may be over cautious but I don't want to have to go through that again . That's why I'm "easing back in to" any sort of repair)
But in the end, after I wiped it down and washed it i have been able to put 75 miles on the truck with new fluid appearing.
