Transmission Fluid leak

[Vroomer]

I parked my coupe on Thursday. Friday afternoon I left for a wedding in San Diego. Sunday afternoon, I came back to this:

I knew the car "leaked a little" transmission fluid when I picked her up. Also, I had the fluid changed and checked at 2002 Haus. Any thoughts for you all?

1972 3.0CS 3-speed Automatic transmission

How much transmission fluid does the auto take?

Sorry, don't know the fluid capacity of the trans but I would guess it's more than what is on the ground. If possible, raise the car and try to ascertain where the leak is and hope it's not the front seal. Do coupes have trans cooling lines to the radiator?

According to the repair CD, the initial fill is 7.63 liters, it also states that the oil change capacity is 1.8 liters.

Yes, there are transmission cooling lines to the radiator.
However, if one of those were leaking that much at rest, you would have a massive leak in operation and would leave a trail of transmission fluid for about a quarter of a mile intil forward progress stopped.
Lets look at the clues.
It has a lovely leak at rest when the fluid in the transmission oil pan is at its highest level.
I would suspect that the leak was at the transmission oil pan gasket. The pan bolts might not be properly tightened, or worse, stripped by hamhanded overtightening. The pan surface must be flat, the gasket must be new and the bolts tightened to spec in proper sequence with a torque wrench.
