Question about On Wet Transmission Pan

Hi, new here.
I have a 2012 5.7L that has served me really well. I have a goal to do all the work on my own vehicle.
I was under the vehicle doing an oil change recently and noticed wetness around my transmission pan along with a red drop of fluid on the fluid level bolt. This was a month or two ago and i noticed it was still there yesterday, image included.
Could this indicate a bad transmission pan? Maybe just the bolt is loose? Could the threads be bad? Curious to hear what you guys think.
The last transmission service was a fluid replacement at 120k, about 1.5 years ago. I'm at 150k now.

 

Clean it with brake clean and see if it comes back.
