ATF Type and how much?

[white89gt]

I am very new to Toyota's so I was wondering if someone could point me in the right direction. I want to change my trans fluid in my 07 Yaris with an automatic trans. What fluid type does it take? I know some 'Yota's take Toyota specific trans fluid.

Also, is the filter able to be changed? And how much fluid does it hold?

Toyota WS is the correct fluid. Filter can/should be changed. A Wix brand from RockAuto is good. A case of 12 will do a good flush.
