SOURCE: Toyota Prius 2008 - Transmission or or fluid?
Here is the answer that you are looking for: Never.
The auto trans fluid in a Prius is what we call "World Spec", and never needs to be changed. Why? Because the Prius trans fluid is not used for hydraulic pressure or cooling the ATF fluid due to the lack of the aforementioned hydraulic pressure. All that the ATF does is perform a "lubrication" function. As long as there is no contamination of the fluid (such as being in a flood), do not bother with it.

This tranny has approximately 13 quarts of fluid. Just dropping the pan and replacing the filter will yield about 5 quarts or so, with the balance still sitting in the torque converter. I recommend just doing this instead of paying someone to power flush the system. There are debates whether or not this method will damage the tranny. When I did it, I got around 6-7 quarts out of it. Use GM's new transmission fluid Dextron VI. It's much better than the old stuff. GM starting putting the Dextron VI in 2009 and newer vehicles. Make sure you know what size your pan is, there is a shallow pan and a deep pan, the deep will have a step in it, the shallow will be completely flat.
There is another way to get rid of all the fluid, but it's very time consuming and difficult if you've never done one before. Involves disconnecting the transmission fluid cooler line at the radiator and having the pump inside the tranny pump out all the fluid for you.
