removing transmission coolant hose 66 dodge dart HELP!

So I just got a Champion for my 66 Dodge Dart, everything seems doable to me I'm just worried about the transmission lines. So taking them off..? is there any tricks or things I should watch out for as Im doing it. I've been dousing them in pb blaster and I have my 5/8 for the big nut but looks like there's a little one too. Do I only unscrew the little one? So can someone give me a quick and dirty tip for removing them without busting anything?
