The only reason you would need the automatic transmission if you need to transmit the mechanical power of the internal combustion engine to the wheels.
Not all electric motors can do that, though. I do agree that they don't really need the gearing of the transmission, but then again, they're never very efficient in the extreme ranges, either.

Then a third, You can't really tell that the transmission is stock, re-geared, or otherwise.

Sure, it's probably safe to assume that you're correct in thinking that it's engine/gen/motor/trans in a line (which, by definition, is actually in series), but you still can't prove it. Kind of hawking a point that you can't back up, isn't it?
