Thanks for the tips.
FYI
I just did a full flush on both our 06 Aveos, used the fluid supply line to the cooler to flush 8 quarts through the trans, and flushed the cooler.
Here is a short video of the process (on a different model) to get a full demo of the process.

Attached is a photo showing the location of the supply line on our Aveos, just connect about 4 feet of (I used clear) tubing, and you are in business. Use the same cautions in the video and don't run the trans dry, and power down if you are learning and see too much air in the line, or not sure how much is in the case. Over all this is a fairly easy process, and saves a bit of time. Go steady and really helps to have a helper on the key so you can just concentrate on feeding fresh fluid.
To make note I used the same maxlife synthetic as suggested and both cars shift great. Great stuff for the money IMO.
