1948 Super 8 overdrive

As I get to know our 48 Super 8 a little better ... I'm still a little perplexed about the tranny. The manual overdrive cable definitely works - as the car seems to free-wheel ( no engine drag when I let off on the gas ). But what does the "trans" switch on the instrument panel do ? I don't detect any noticeable sound or change in feel of the car when I push this switch. Is it an option that doesn't exist on my car ? a faulty switch ? neither ? And how would I differentiate between an R9 and an R11 ? Just a start to a plethera of trans ?'s. Thanks , BigT
