2016 edge transmission leak

Trying to help my sister out with a transmission leak. I see the lines from the cooler bypass are nice and wet (red fluid). So I’m guessing these are the source. BUT I also noticed a small crack around the bolt in the case. It looks pretty dry to me.

So question, should I plan on replacing the AC condenser here as I believe it also functions as the trans cooler? Any chance the leak is just in the line? If it is just the lines and I replace them am I going to have to flush and refill the condenser as well? Any help or guidance here is much appreciated.

They are combined as a unit but why do you think that’s where the leak is? The picture you showed makes it look like the O-rings at that fitting are the leak points.

Clean the entire area of the car first and then look for the source of the leak.

Ok, will do. Should be easy to replace the rings if that’s the leak point right? Or would I have to get a new bypass valve?
