Most likely it's you oil filter housing gasket. I have a 2013 C250 and had similar issue.

I just can’t figure out what the part is I’m thinking it’s the oil cooler line for the transmission maybe ?

Hopefully it is under light pressure. When I had no money and a bad car, 1978 Renault R5, Le Car, I 'fixed' a leaking hose by cleaning it up and wrapping it with duct tape. Repair lasted for a couple of years. These days, you can get duct tape in any color, including black. Probably not sanctioned in the WIS.

If it is the trans fluid line there should be a part# stamped on one of the fittings.

That leak looks like oil to me.

I would thoroughly clean the area then try and see exactly where the leak is coming from. If you havent already.

I was reading thru a thread and came across an interesting photo. It shows the transmission lines and it appears the lines have some type of cover over them. Made me think of this thread with thinking the line is cracked. It could just be the covering/coating on the line.

2013 transmission should have blue fluid I believe. The leaking fluid in the photos looks like oil.

I could be wrong.
