I just did a drain and fill on my camry. I used Mobile1 ATF (as recommended by Fenixus, thank you..), bought from advancedauto with online coupon for around $5 per qt. Easy job. Make sure you won't overfill the tank. Mine took exactly 2.6qt to fill the tank. 10mm hex key (from harborfrieght for $6.99) is all you need to do the job.
