I had the same thing happen to me. I was sitting in traffic due to damn traffic and the car began to overheat. I couldn't move, so I was forced to sit in the traffic.. The engine got so hot on the way home (had to drive it cuz I couldn't pull over due to traffic!) that it burnt the transmission slap up. The car wouldn't even pull in the driveway, and I had my foot mashed on the gas.

I took a wild guess and thought it might be the lower intake gasket, which I was correct. It took about a day to dismantle everything, then another day to install everything back together. It's not that hard, but it's down at the bottom of the engine in the lifter valley. It's a good expierence tearing it apart and putting it back together. If you attempt it, I'd suggest getting a Haynes manual so you can find out the torque specs and teardown instructions (if you haven't done this before)
