I have noticed mine doing it from time to time under the same conditions - going downhill or coasting at approximately 5-10 mph or less and then pressing on the gas slightly. I think it is just the transmission going into 1st gear instead of staying in 2nd gear, thus the revving. On flat ground it will lock into 2nd gear and continue on. Mine also seems to do it more whenever the tranny is cold, although that isnt the case every time.

I think it is part of the logic that tells it to downshift when you are going downhill or coasting. It is a nuisance at times, but I dont think there is anything wrong with it. Mine even does the same thing at faster speeds after it downshifts going downhill, then press the gas again and it stays in that same gear until you let off again or gain an amount of speed that makes it upshift.
