I have hit the Rev limiter many times in my 2000 S10. Everything still holds together... for now. lol.
I would check the flexplate. Also, probably not the cause of it, but check the Dust guard on the Drive shaft... thing. please excuse my lack of termenolgy, for the name of the part excapes me at the moment. It's the support on the shorter piece of the two piece drive shaft. Mine came loose and cause a high pitch noice becasue of the vibrations. Like I said, probably unlikely.
Branden.
