Mine has done this a few times as well. The difference is mine does it at low speeds, and in second gear. I notice mine when going through school zones. I have talked to Bill , but my problem is that I can not make it happen when I want, so it is hard for Bill to fix the problem. My RPMs jump about 200-400 and the TQ is not locked and it does not seem to be jumping in and out of gears.
