Rather than just replace it, why don't you take a sample and look at it. I have a 2008 RAV4 and I did just that. My conclusion was the fluid looks just fine. So I didn't change it.
A well designed transmission does not "burn up" the fluid, hence no reason to change it. A poorly designed transmission DOES over-heat the fluid and they do need changing (doesn't solve the crappy design though).
A good transmission will burn fluid if left in for too long. What is too long? With normal driving 60-100K miles likely. It would take some UOA's from ones transmission to determine what is the ideal mileage for ones vehicle.
