No, the "tighten to 20 lb-ft and back off 1 3/4 turns" is ALWAYS the right adjustment. I think your shifter adjustment may not be letting the valve body get all the way into reverse, but hit it when you shifted into neutral and back.

I assume your rear wheels are off the ground and you are observing the driveshaft? Not unusual for the tranny to windmill forward in neutral, but if you put the brakes on and revved the engine, you should not notice the engine straining. In high with the brakes on you should notice a definite load come on the engine as you rev it up. Same in low or reverse. If you feel no resistance in H, then either the valve body is still not set right, the high clutch discs are completely toast(Which you would have noticed by a lot of smelly debris in the pan), or there is another mechanical problem in the trans such as the bushings in the high clutch pack having spun out of position.
