Clutch Sqeal when shifting


overtime

Recommended Posts

Need some help. I have read all of the clutch and transmission threads but have not seen where this issue has been mentioned. I have a 2008 GT500 with 540 miles (purchased in May '08, built in February '08).

 

I've noticed that when I shift and release the clutch quickly, I get a sqealing sound. The higher the RPM, the louder the sqeal. And no, it's not the rear tires. :) However, if I release the clutch more slowly after the shift the squealing sound does not occur.

 

Is this some sort of clutch break-in issue, or do I have a warranty issue.

 

Any help or suggestions would be greatly appreciated.

 

Thanks,

Overtime

 

PS: I will be at the 31st Southern Illinois Mustang round-up this coming Saturday in Alton, IL. If any of you are planning on being there, it would be great to meet you.

Interesting that you mention this. Mine has had that "sqeak" when hard shifting from day one. I now have 2600 miles and it still does it. I feel that it is a suspension bushing sqeak. I notice it only when the windows are open. Could this be what you are concerned about?

This may be related to a release bearing. Check these topics out...

I believe this is a different issue. I do hear the release bearing when depressing the clutch at idle, but it fully releases once the clutch is near and at the floor. My issue occurs during shifting and is a completely different sound tone.

 

Thanks for your input.

You sure it is not the Supercharger Belt slipping. There is a bulletin from Ford on this with fast shifts and/or high RPM shifts.

 

Just a thought.

 

I did think of the SC belt, and that could be it. Is there any way to check it without actually driving and shifting?

Not really, although I would tug on it a little and see if it seems loose. Easiest fix would be the Metco Aux Idler kit, you dont need the upgraded pulley to use it and it increases belt wrap on the pulley, and should fix your issue.

It's not your clutch, it's your SC belt slipping on the pully. Perfectly normal, and as stated by others here, the issue can be resolved by changing over to a Metco pully with a Goodyear Gatorback belt or by adding a aftermarket belt tensioner to the stock setup.

Thanks CRQuarto and Son of GT. If this is the case, I might as well switch to a smaller pulley, add the tensioner, and enjoy a few more horses. I was hoping to wait until the fall to do these mods, but I can't stand listening to the belt squeeling. Hopefully the slippage won't damage the belt (or anything else), until I can get it taken care of.

Nothing like a good excuse to do a mod! Doooo iiiitt..... :drool:

Change the belt and see if it goes away. If it doesn't then at least you have a spare. I did that with mine and fixed my problem after replacing two pullies (including my metco idler bearing, which was notchy as hell when rotating through the fingers).

Do you have any suggestions on Belt brand (ex: Goodyear Gartorback). If you have the size, that would also help.

 

Thanks again for everyone's help.
