The BTR is an all Australian fully electronic box. From memory the AOD is a full hydro box based on the C6 with an added overdrive. My old Autotech teacher had 1 in his 1977 F100 running a stout 351C. He said the box was the only reason he drove the truck daily as the fuel usage would kill him, and it was straight gas! The AOD proved plenty strong because he was always doing burnouts in the thing with 30" mud tyres.
