Leaking transmission cooler lines

[Jobi-Wan Kenobi]

Noticed here a couple weeks ago that I'm going to need to change transmission cooler lines soon. I have the KNP RPO code and looks like there's 3 lines for it. Should I just figure changing all 3?

Where are they leaking at?

@rockola1971 what i had found so far is where they connect to the oil cooler.
