what transmission?

Does any one know what 4 speed transmission came in a 79 Trans Am with a 301 pontiac? I think it was either a m22 or a super T10 but i cant seem to figure this one out.

It could be either a saginaw or a T10. They used both.

Thanks thats what i got out of the hanes manual here is why i was asking

Got a couple of days left but im thinking of putting a bid on it. I sent a message to the seller and he said its a super T10.
