Slight transmission oil leak

I know this is probably a simple fix and a "duh" question but I got a little drip at one of the hose connections. I can tell its loose because I can move it by hand. ----Problem is, when I tighten it the whole hose moves and the tension makes it un-loosen again,,, and it makes the hose kink up and I don't want to rip or tear it. So I'm trying to come up with a solution.--- I wanted to take the hose out and put it back in with thread sealant but I'm afraid if I take that hose off, transmission oil going to come oozing out... But I took pictures and wanted to know what you experienced hands would do in this situation.

Thanks in advance and safe trails

 

Once the line is off will all the oil come pouring out?

 

Sounds good. Thanks man

I've never topped a transmission or check levels, I usually let speedco do it. But I assume the check will be on the side somewhere and the fill on top?

 

Thanks. Yea they're on there real good.

 

I had to be creative and make two breaker bars out of a pvc pipe and another out my winch bar. I broke em lose finally. But before I got to that point i damaged the hose and put a small hole in it from kinking it up

---so now, I don't know. I fixed the leak and got another one lol... Will probably have to build a splice with a piece of brass or get a new hose and re use the fittings
