I would think that the transmission should be The same as what came in the R/T and GTX where as the 383 cars used the Roadrunner and Super Bee transmission.

Everything that I’ve heard was that the 383 cars came with the 091 and the M-code came with the 093 Roadrunner HD transmission, which, I believe, also came in the 440-6 Roadrunner. My GTS was missing the correct engine/trans when I bought it.
