Transmission Cooler Line Repair

I finally got my transmission parts from A&A Transmission and I scheduled a 3 day weekend next weekend to put it all back together. ..been working 6 days a week...ugh

Anyway, when I pulled the transmission out 3 weeks ago or so, one of the transmission cooler lines "twisted" off...

These are not high pressure lines - correct? Can I just use some rubber hose and clamps for repair or do I have to get fittings and make flares etc...only needs to run a year or 2 until my next engine swap...
