How often can these be shifted while in while in motion? If any, what problems have occurered and what should we do to prevent the problems?

We used the DeWalt trannies with CIM motors last year and had no major problems. They will shift on the fly as many times as you want them to. Those noises you hear are normal and shouldnt cause you any problems. The only mistake we made was that, initially, we didn't replace the case, which allowed the plastic ring that actually does the shifting to expand and warp. So just make sure that you replace the front section of the drill case to avoid this. Good luck!
