I have the same problem with our 24 in the 35-40 mph range. Makes a lugging noise because the transmission seems to have upshifted too soon. Almost like a bad shift point probably meant to improve mpg or something. Just had an oil change at the dealership and forgot to mention this. Hope it's not damaging to engine or transmission.
