Maybe not fine
It has been said that paper lint or textile lint particles can make their way into automatic transmissions via the dipstick, where they can get stuck in the valve body and cause problems. I have no idea how much truth there is in that statement, but I now wipe the transmission dipstick only with my fingers. The oil dipstick I still wipe off in the traditional manner.
