Ok, I think I understand, but if not, sorry! You're going from 2nd. low range to 2nd. high, right? Here's how I'd do it: With power applied, move the splitter knob to the "high" position, the quickly ease off the gas and tap the clutch. This allows the planetary unit to shift in a no-load situation, and it's like making any other gear shift. Downshifting is accomplished the same way, but it's usually not necessary to declutch, just pre-select low range, and quickly back off and re-apply power. By making the shift selection with the load on, the diaphragm has time to preload the shift shaft and make a quick change to the other ratio. If I'm not understanding the problem, try to explain it a little more completely.
