How do you know that it was a transfer? Did you have someone make the transfer and apply it, or did you buy the shirt that way and assume it's a transfer?
It's possible that the shirt was printed with water based inks. Water based inks have little to no hand. Since you said the print is black, I'm assuming that the shirt was light colored? If so, it's probable that you've got a water based print on a 100% cotton shirt.
Water based inks become part of the shirt rather than sitting on top of the shirt like plastisol. You can also get the same effect on dark shirts that are 100% cotton by using discharge inks.
But I really doubt if it's a transfer. There are no water based transfers, they're plastisol. Of course there are some transfers with a very a very light hand. But I doubt that they are so light that they feel like it could be dye sub (or feel like it's part of the shirt instead of sitting on top).
