See if you can get underneathe the vehicle to see if you can pin point where the noise is coming from (may have to use a lift).
Also, my first thought was the Vehicle Speed sensor (VSS). Mainly because of the rpm's going a little high. However that still does not explain the noise. So try to find the origin of the noise before considering replacing any parts.
