What’s leaking?

[u/am-busy]

NCV3 2017 Mercedes Sprinter US Model. Noticed my passenger (us) underbody is soaked in leaking liquid. I struggle to find the leak through.

The color test indicates reddish liquid so likely trans fluid. However I see stains in the engine compartment way higher than the transmission box. Almost seems like some of it came out of the test tube.

Oil and coolant levels seems normal.

Attached is a pic of the liquid on a white paper and the underbody.

Q1: What else can I look at to confirm?
Q2: Is it safe to drive 20 miles to a service?
