How to Change Trans fluid in an 03 Tiburon

I am searching for DIY instructions on how to replace the transmission fluid on a Tiburon. The dealer quoted me $200 on a fluid flush and refill. I have experience changing trans fluid on other vehicles but I'm not familiar with the automatic transaxle on the Tiburon. To my knowledge, a repair manual (such as Haynes) does not exist for the Tiburon.

The car is a 03 Tiburon GT V6 with the auto transmission.
