Packard issued a statement to dealers explaining the correct procedure for locking out the new overdrive on December 23, 1948.
Packard records indicate that Eights through engine number 272006 used the R-9 overdrive. Eights after 285157 were equipped with R11s. For Super Eights, those up to 424978 used the R-9s. those after 427710 were equipped with R-11s. Customs up through 610359 were equipped with P-9s while those after 611500 were equipped with R11s.

During this gap, Packard was having trouble with obtaining parts from Borg Warner, among others.

Obviously, this leaves quite a few cars that could have originally been equipped with either. Couple that with the retrofit kit and your car is any ones guess.

As mentioned above check the components you have for identification. One additional identifier is that the cable for R-9s and R-11s run down opposite sides of the engine.
