Thank you for your responses.
Got some paper under the car. The stains were in the area below where the gear shifter sits. I can't be more specific, I don't have jacks, just my old maglite.
The stuff didn't completely dry out on the paper. It doesn't fell greasy, it's black, and it smells a bit like gasoline.
I don't think it is engine oil or Atf , as both look clear on the dipsticks. Could it be P/S fluid?
