Just one other thing I remembered. 2 of the 3 times I mis-shifted in my car, it caused the flex-plate to come loose. What happens is that the sudden high rpms cause the flex-plate to deflect, and the flywheel bangs into the flexplate to crankshaft bolt heads, and the impact causes them to come loose.
I can ALMOST guarantee that that's you're problem. You can confirm that by removing the dust shield between the trans and motor, and grabbing the clutch/fywheel/flexplate assembly and attempt to move it around. If it does move, even a teensy eensy weensy bit, you have problems. And even if it doesn't move by the force of your hand, it could still have a couple of bolts loose, causing it to vibrate against the crankshaft.
In a situation like this, I would HIGHLY recommend pulling the trans, and checking said bolts! Otherwise, you could be the next victim of a clutch flying through the bell housing of the trans, and out through your hood! The possibility is there that you could be seriously injured from such an occurrence!
Also, if you do have a few bolts loose, don't cheap out and just tighten them up. Replace the bolts, and loctite them. And if the bolt holes in the flexplate are oblong shaped as a result of the bolts loosening, replace the flexplate. Otherwise, you'll be asking for the bolts to loosen up again, without having over-revved the motor.
Exactly what happened to my car a couple years ago, heres the noise it made...
