Change from 4-speed to 3w/OD

AJ/FormS said
All my833s have been fully synchronized,od or not, as was the A230

But the A745 and A903, three-speeds were not
I think the 230s debuted behind the 340s in the 1970 model, then were the only 3-speed from 71on, or so.

I agree, my 71 slant duster has its 3 speed, fully synchronized.
