After very carefully reading the fine print in the extended warranty and determining that it does completely cover the cost (parts & labor) of a replacement transmission, I'd start driving it like I stole it! I wouldn't bother changing the fluid at this point. Definitely do bring it back to the dealer, and make sure you have their own copy of the repair order with the exact nature off the problem listed on it. You may have to go back more than once.
