Re: 1940 overdrive?

Nomenclature question:

The 1951-64 Studebaker V8 has a Borg-Warner T86 transmission and an R10 overdrive attached

The 1955-56 Borg-Warner V8 transmission is a T85 and the overdrive unit is an R11.

However, it seems some knowledgeable Packard folk refer to the transmission with or without overdrive as an R9 or R11. What's correct nomenclature for a standard transmission with and without overdrive?
