Good Morning All!

I am a proud new owner of an 08 Dolphin Gray S4 Avant! Please excuse my ignorance with this question as I am still learning my way around the car and all it’s greatness.

Now to my tech question, while checking out underneath the car with belly pan removed I came across a leaky plug/sensor located on the front driver side of the transmission plugged in right above the ATF oil pan facing the front of the car. Also, it is right next to the green/silver manufacturer part # tag.

What sensor is this and is it a common leak point? (118,xxx miles)

I’ve searched but have not been able to figure it out. Ty in advance!
