Thanks guys and Moparts Sorry but the 9G296333 could not be an A12 transmission as A12 were only built in the Lynch Road "A" assembly plant. "G" is the St. Louis assembly plant code. And the only way to find an A12 transmission is if one can prove it matches an A12 VIN. Your RM23M9A is proof that you have an A12 regardless of the last digits. The "M" "9" and the "A" along with the B-body designations (RM21 or RM23). There's nothing different about an A12 automatic 093 transmission, folklore claims the A12's had a "HEMI" automatic trans and that is not true. They are the same as any '69 383 or 440 HP engine automatic 727 transmission in the '69 B-bodies. I would just stick (not a pun) with the transmission you have now, other than the "G" in the serial number the internals should be the same if it is an 093 trans. Mike
