Question WHAT IS THIS NOISE? 2003 Mustang Gt (VIDEO)


Any help with what this noise is, or what is causing it, or what it may be, would be GREATLY APPRECIATED!!!!! Sounds like it's coming from the transmission or clutch. It is not coming from the motor or the supercharger. It does it intermittently but constantly just like in the video. It starts after the motor is warmed up and at temp and usually around 10mins or so driving. The sound does not change with the RPM, meaning (shown at end of video) when I rev the car it does not get louder, the pitch does not change, it ALWAYS sounds exactly like in the video and doesn't matter if I have the clutch in or out, doesn't matter what gear I'm in or in neutral, doesn't matter if I'm parked or driving, doesn't matter if I'm doing 10mph or 100mph, doesn't matter what I'm doing or the car is doing, it always sounds the same and does not change in anyway. Please send any thoughts my way!!

Let me know if any more info on the car is needed. I want and need (it's driving me crazy) to get this fixed, but don't want to dump a ton of money just to diagnose the cause of the wicked witch screech!! Please HELP!!

Not gonna lie, sounds like the ac compressor kicking on and off like it's undercharged and squealing.

Sounds like it's haunted. I'd take it to a catholic church immediately.

Thanks for the responses! I really appreciate it and I'm pulling my hair out annoyed with the sound!!!
I didn't take video from under the hood because the blower drowns out the sound, and also cause the noise when laying on the ground next to the car or under the car, it is no question tI on coming from the Trans/clutch. I will post another video of under the hood (when I get a chance) just to see if it helps figure this out, but if you were next to the car it is clearly coming from the Trans or clutch. I have never heard a thrust or pilot bearing make that noise, and it would change with rpm, and pressing clutch in and out, it wouldn't be consistent with no change.
The noise is so loud and annoying the Catholic Church wouldn't touch it. Even they are afraid of the demonic screech, and told me to click my heels three times and if it didn't go away then to drive it till it fails, then put it down for good using holy water and silver bullets!

Dont know much about transmission internals, but could one of the oil passages be clogged up or something? Kinda sounds like it could be a sort hydraulic or pressure relieve sound. I feel like this would be more of an auto trans issue though.

The problem with diagnosing is that you say the noise does not increase or decrease in pitch with rpm. And without rhyme or reason it kicks on and off.

Can you pull the serpentine belt and run the car to see if the noise is still there?

How are you sure it's coming from the trans/clutch? We are not there in person to pinpoint the location, so you'll have to describe how you know that.

I am going to say it sounds like the a/c clutch also.

Sorry been away for awhile and have had nothing but bad weather up in here mass to get a running video under the hood. I probably can get an under hood video tomorrow.
I'm sure it's coming from the clutch/Trans area as when the car was up on the lift, and your under the car, it is clear as day coming from there. At first I thought it was a belt pulley bearing up front but it's not.
I clearly understand it's hard to diagnose from a video. I just need something that it logically could be to try instead of replacing 10 parts before I get the issue. My other huge hang up is I REALLY REALLY REALLY don't want to leave my car at some shop where some kid takes it out and beats it up. The car can get away from you extremely quick, and have a hard time trusting a shop to take it.
Anyway, thanks guys for the replies. Please tell me if there is anything you want me to get a video of that may help point me in a direction. The nice weather is finally here, and it's damn embarrassing at a red light with that horrible noise kicking on and off. I NEED to get this fixed asap!!
I will pull the front belts tomorrow anyway and run the car even though I'm positive it's not coming from up front, but hey you never know, and I will get an underhood video up tomorrow too.
Thanks guys!!!!!!! I will try anything to figure this out so please keep ideas coming, and I will post the out come of what it is, when it is found, and how it was rectified to hopefully help someone else in future that may come across this issue with their ride.
