You're preaching to the choir here, but I had a similar incident with GM with my 1990 ZR1 when it lost a tooth in the second gear. So I couldn't use second gear at all. It was under warranty and when I took it in they tore it down and fixed it. I went to pick it up and they said it wasn't covered because the spline shaft showed evidence of power shifting and abuse (NOT TRUE!)
I paid out of pocket and wrote letters to Chevrolet, the dealer I bought it from, the President of GM and finally after 9 months of bugging everyone including a letter to the Corvette plant in Bowling Green I received a check in the mail from GM for the $1643.
I wrote eight letters and sent four of them registered mail and talked with William Cooksey, Corvette plant powertrain manager, on the phone and by mail. I'd try to talk with someone at AM General and keep calling and writing. My message here is to not give up and bug everyone. I called the dealer that repaired it on a weekly basis to see if they had heard from GM and they finally got sick of hearing from me!
