It depends on the design of the transmission. I've seen transmissions that use gear oil, ones that used modified 5W-30 motor oil, and of course ones that use some form of ATF. Me personally, I prefer to use something compatible with what is supposed to be in the transmission if not what the manufacturer specifies. To each their own on straying from that. I don't pay your bills.
