If the pan's cracked, you need to replace it. If it's a cracked gasket, just wait until you can get a new one, and see if you can get your money back for the defective one.

Also, I would avoid driving the car until the issue gets solved. You run the risk of losing trans fluid while running, or introducing air/moisture into the pan as it cools down after running.
