2006 GT S197 Rattle/Clicking when clutch disengaged

Hello, I have a 2006 Mustang GT Manual Transmission. Everything is stock. 73500 miles. Original Owner.

I have no problems shifting into any gear. The clutch does not slip when starting out in second or third gear. But...

After accelerating normally in first gear, when I push in the clutch for the shift to second (2000 rpm or higher), a loud rattling sound happens for about one second (until the rpms come down). The sound is kind of similar to the "wheel of fortune" noise when you spin the wheel, but deeper. If I keep the clutch in, the rattling stops, and then I can let the clutch out and accelerate normally in second gear. If I let the clutch out while the rattling is happening, I can accelerate but the loud rattling/clicking continues even louder and faster. At this point, I press the clutch in, wait for the loud rattling to stop, then let the clutch out and accelerate normally. This mostly happens on the transition from first to second and from second to third. It does not happen in the higher gears very often. I seem to have full power when I accelerate in any gear as long as there is no rattling. It usually only happens during cold days or in the morning but it is starting to happen more often than that. After I have driven for 10 minutes, the rattling will not occur when I push in the clutch and it is harder to recreate the rattling. Also, it seems to happen more in a turn than when going in a straight line. For example, when I start off in first gear and make a turn, half way through the turn I push in the clutch for the shift, the loud rattling starts. Lately, I have been keeping the car in first gear through the entire turn, and then shift to second after the turn is complete, and the rattling is kept to a minimum. Or, if I am coming off of the freeway after I downshift to third, and as I am going around the cloverleaf with the clutch engaged, while throttle steering the rattling will occur as I let off the gas.

Anyone know what is wrong?

Thanks for the help.

I have just had the same exact problem with my 2005 GT convertible with 45k. It turned out to be an "inspection plate" under the car that covers the bottom of the flywheel. Apparently this is what is removed to inspect the flywheel for wear and soforth. Anyhow, it turns out that the plate was bent and rubbing against the flywheel. Your symptoms were the same as mine but mine went away once the car was warm. Hope this helps. Now the battery went bad and it won't start. That's ok since the weather is bad and the car does not get driven in any inclement weather.
