All I can say is good luck dude! I had my transmission fail in my last car - an auto Grand Prix. I had transmission strangeness for quite a while before (my suspicion), and was even under aftermarket warranty and took it to the dealer a couple times, then finally lost 1st gear one day, then reverse, this after the warranty expired. I was able to drive it to a transmission shop without 1st. Like I said, I had the car in to get it checked out before it failed, but since I didn't have a "failure", the warranty doesn't pay for taking a transmission apart for diagnosis. I listened to the stupid GM dealer shop and thought things were just getting older - they weren't too concerned. After it failed, I wished I had paid whatever I needed to out of pocket to get it checked out prior to my warranty expiring.
