This is not one of the easier jobs to do on the 2.2 mate.
Basically, you need to remove the top filling bolt, and then also remove the lower level bolt, and then fill the transmission til its level with the lower level bolt.
Too little, or too much oil can be detrimental to the transmissions health though. Why are you wanting to change the transmission fluid, and do you feel confident in the task?
I have a how-to I made somewhere, but it doesnt actually have pictures from the car on it - They're images taken from software, so it doesnt help someone who doesnt actually know where bits are located. I'll upload it and link it.
