[quote]

1939 was the first year for column shift and also for overdrive

The 1939 overdrive was an R6, R9 for 1940 to 1948 and R11 for late 1948 to 1950

There were 2 different versions of the R9. The regular R9 was used for the junior 6 and 8 cylinder cars. Senior cars with the 356 engine used an R9A which had a 4 pinion planetary instead of 3 and a larger one way clutch.
