Well I'm not a DCC guy but your idea of slack in the gears does sound plausible. Do you have any other P2K units giving you that same problem, A few of mine suffered cracked gears on the axles, something like that could be the problem also. I was able to fix them with a drop of CA. you may want to check them just in case.
