I would say that is the original transmission for your car.It has the right production date window.I have seen other A833's with the VIN # stamped and no other info on the pad.I have a 2817 A833 on my database that was for a 422 SPD as well as a 2819 A833 that was for a 430 SPD.Your RR should have a sequence # in the 9G251xxx to 9G2522xx range.
