Oil/ATF leak between oil pan and transmission pan

I was changing my oil and doing a general inspection of the underside of my car today when I came across this, it doesn’t really smell like much of anything but looks a little lighter in color- my initial thoughts was oil but maybe it is ATF? No leaks last time I was under the car (10 months and ~20k miles ago), and oil level stayed at the full mark for the past 9k oil change. Here are some pictures, I’ve seen some talk about rear main seal leak, others about transmission fluid leak, I’ve cleaned up the area and will check it again in a week or so to see if there’s any more fluid- looks like it is leaking down in front of the transmission pan and then blowing back down the pan towards the rear of the car

If its not dripping from the top, its probably oil pan. That's where i had oil before my OPG was replaced under warranty. Literally that same bolt was oily like that.

That was one of my suspicions, the dealer replaced that seal November 2022 so hopefully they will warranty it if it turns out to be it leaking again

Most dealers offer 2 years/unlim miles on their parts and labor but you'll have to check

Both? It looks like dirt and in some places wetness from a fluid
