I'm sure they have an interline agreement. Are you on one ticket?
2nd question: Do I have to clear immigration in GRU or can I stay in a sterile zone?
You stay in a "sterile zone" - just make sure you don't turn the wrong way. Everytime you see an agent of some sort going through the arrival corridor, just keep saying "Buenos Aires" and people will point you the right way.
3rd question: Is there any chance I get through all of this and actually make the flight?
Yes, it is an easy, albeit a bit annoying, connection. If you are on time, you will be just fine.
Thanks for the great answers! Do you know if TAM and Delta are in the same asa (wing) of Guarulhos? That would certainly increase my odds. Also, I am traveling on one ticket.
Finally, is there anything I can/should do to help ensure that my bags don't get stuck in GRU?
