Welcome to the forum!

You'll probably need to describe the noise a bit better. If I'm understanding you correctly, there are two issues, one is a noise that is there just with the engine running, even at idle. The other is with the transmission/engine rpms being higher than usual? Also, at idle, is the engine smooth or is there a lot of shaking/vibration? Did you notice the Check Engine or Transmission light illuminated in the instrument cluster during the drive?

Also, you should consider moving this thread to the more specific Ford Taurus forum.
