WHISTLING NOISE

Honda Accord

Please help, I just spent a lot of the money I earned as a private during Operation Iraqi Freedom (Phase I-II) on a 2005 Honda Accord EX Coupe Manual and this is driving me crazy.

Manual Transmission 2.4L 4 cylinder.
It's got 34000 miles on it.

My car is making a very high pitched whistling noise, a continuous beeeeeeeeeeeeeeeeeeeeeeeep that increases in pitch and volume with RPM.

Noise is present when:
-Clutch is depressed and car is in motion in any gear.
-It starts around 1800 RPM and is loudest when the RPM's around 2000-2750, and when I'm moderately accelerating.
-It's continuous and doesn't go away over time (even after hours on the road).
-It's somewhat faint but I can definitely hear it, on a noise scale of 1 to 10 I'd say a 2 or 3.

Noise goes away when:
-The noise goes away completely when I push down on the clutch and cruise on neutral while moving at any speed. I can rev the engine at this point and there is no whistling noise.

Noise chirps temporarily when:
Sometimes it chirps when the road condition changes and I go over soft bumps but it'd come right on a level road.

Thanks in advance.

You mention that the noise is there when the clutch is pressed and dissappears when it is pressed. I take it you lose the noise with the clutch in and the shifter in neutral. Noise comes back when the tranny is in a gear whether the clutch is in or out.

If you interpretted that correctly, have you checked the level of the tranny oil?

I've taken it to the shop and had all the fluids flushed out.

The noise disappears when I push the clutch pedal down regardless of the shifter position, neutral, 1st, 2nd, doesn't matter as long as I push the clutch pedal down.

I rev up the engine when parked (being manual transmission, not moving, in neutral, and with parking brakes on), and it does make a similar whistling noise but it's definitely not as loud.

It seems as though the noise is always there when I rev the engine to about 2000-3000 rpm no matter what gear I'm in. But it gets worse and worse as I change the gears from neutral to 1st to 2nd. To 5th. When I push in the clutch pedal to change gears, the noise goes away but comes right back at a higher pitch and louder volume when I depress the clutch pedal and engage the next gear.

I put this as clutch assembly related and I might stick my neck out and say that the throwout bearing could be the issue. When fully engaged it has full pressure on it and it complies. It will probably get worse but not sure of the rate at which it will go down hill.
