My apologies, I was not very clear in explaining the problem. So I went out to test drive the vehicle and check when the noise comes on.
I also forgot to mention that I have a 6 speed manual transmission on my 2007 Nissan Versa.
So, this repeats basically on any gear:
Let's suppose I am driving at 40mphs on 4th gear and 2500-2600rpm. When I press the gas all the way in, then the car makes the noise and the car starts slowly picking up speed, until at about 3500-3700rpm, going at about 60mph. Then it stops making the noise.
That's probably as best as I can describe it. Again, I tested this on other gears (except 1st) and it happens on all.
My apologies for the unclear posts.
