Hello All -
I've had a persistent rattle that I've had trouble duplicating when putting the car up on stands for some time, but recently, it's gotten much worse.

First, car is a 2006 Mustang GT coupe with TR-3650 manual transmission, original clutch with a short throw shifter and 48k miles.

Originally, the rattle/vibration was present at startup, until the car warmed up, and would only occur when the engine revved to a certain RPM (and its subsequent resonant frequency). I assumed this was a loose heat shield or exhaust bolt, but was never able to find it. Awhile back, the rattle got worse, and started being persistent from startup to warmup. Again, I put the car up on stands and couldn't find it.

Last weekend, I changed the oil, and while I had it on stands, I checked again, and found that the noise seemed to be coming directly from the bellhousing, where the engine meets the transmission, and it is persistent until the engine warms up. Once it reaches a certain temperature level, the rattle changes, and instead of a persistent buzz, it only occurs when the clutch pedal is depressed, but will occur when shifting between all gears.

My father-in-law and I spoke on the phone, and though he's unfamiliar with the TR-3650 and S197s, he seems to believe it's a bad throwout bearing.

Thoughts? I'd really prefer to not have to do a clutch on a very lightly modified car with only 48k miles when it's not slipping, but the buzz is driving me insane!

It could be the dust plate , some were missing screws and rattled. Here's a link to a thread on another forum about it

Holy crap! That seems to be it, exactly!

I'll get some double sided tape and try to tackle this on Sunday!

Thanks!
