2019 Suburban Trans Fluid Leak

[Djohnson99]

I have a 2019 Chevy Suburban LT 2WD with the 6L80. I’ve been trying to chase a trans fluid leak from the front end near the radiator / condenser. I’ve replaced all the cooler lines with AN lines & connectors, have an external trans cooler. The external cooler and lines are not leaking at all.

I did some research and everything I found online for 2019 + says that the trans lines go straight to the AC condenser (skips the radiator). Is the AC Condenser is what is leaking the trans fluid, how can it leak trans fluid but my AC works just fine?

Or does it go through the radiator as well from somewhere I can’t see? (the AN lines I installed didn’t go through the radiator)

Trying to do my due diligence before replacing parts that may or may mot
Fix the leak.

Pics of the truck, please.

Nothing on the floor/ground after the truck sits for a while to give you some idea regarding approximately where the leak is?

Someone more familiar with your specific model year will chime in regarding your questions.
