Makes a fairly loud..whirring?... noise when starting in neutral, gets quiet when you put it into gear, and then makes noise taking off. Nothing changes with RPMs, it runs, and shifts perfectly, just that "expensive sounding" noise. Well, they call 'em Hundred Dollar It was, however, a very nice 3500 miles to AZ and back, all on back roads. Pictures sometime this week. Any guesses on the noise?
