adjusting transmission vacuum modulator

Hold the reprimands! I've looked and looked in the archives and cannot locate the answer to my question. I want to soften the shifts on my 300D. First replaced a leaky vacuum modulator. This was an improvement but she still shifted a bit hard. Next I fiddled with the bowden cable. Got it to shift softer but at the expense of shifting too soon. I had read that the bowden only affected timing, not softness but it surely seemed to influence both. My question at this point is ------ when adjusting the vacuum modulator counterclockwise for softer shifts, are there just three positions (in the slots) or can I turn it several revolutions (essentially 6 or more slots)? I've read and tried to understand some of the excellent advice about orifice restrictions in parallel vacuum circuits and am coming closer to understanding --- but I could surely use some dumbed down advice. Again, thanks in advance for the help. This forum is great!
