Since I work for a parts supplier to Honda were do you think the new trannies are coming from?

It may be wrapped and cleaned and polished but major pieces of that tranny are reconditioned parts. Trust me if no car is recieving that tranny there isn't a Honda plant or subcontractor making that tranny Japan or United States. Since Honda is a J.I.T. supplier there isn't such a thing as a J.I.T. New Old Tranny warehouse.

The major case and spline shafts are likely key pieces cast or forged at Honda factories, and those factories aren't casting new pieces for your out of production tranny--the same goes for Honda engines, there aren't any new old F-series or J-series(ver 1.0) engines to be had anymore.
