The Blue Ox Base Plate Kit - Removable Arms # BX2803 is a fit only for the manual transmission not because it wouldn't fit the automatic, but rather because the automatic transmission is not able to be flat towed.

You also probably need a bike frame adapter bar like the Swagman Deluxe, part # 64005. This creates the horizontal tube to hang the bikes from to keep them level if the bikes don't have that bar.
