Well, I just finished changing the CVT fluid after doing my rotors and brake pads. It was the first time I've ever done either of these so it took me essentially all day (worked completely solo, ~10 am to 8 pm with zero breaks in between) although a good portion of that was driving to break in the brakes and heat up the CVT fluid to check the level while hot.
Below is a comparison of new (left) vs old (right). And no, I'm not storing it in these containers, I did this only to get the same amount in as I drained out). I did a drain and fill only and about 5 and 1/2 quarts came out. It's a good thing I sprang for the 6 pack of CVT fluid (I used Valvoline CVT fluid which is Nissan NS-2 compatible). What is shown in the containers below is not the total amount of fluid that came out; there is still some sitting in the drip pan to the right.
What's interesting is that I ordered a crush washer from the Nissan dealership (50 cents with tax with store pickup), and they cancelled my order and told me to just come in and pick it up. Went in and they gave me one for free. Another interesting fact is that there was no existing washer in the transmission pan so maybe I didn't even need it to begin with. I installed it anyway.
Even after driving for quite a while to give the new and old fluid a nice amount of time to mix I found that the resulting fluid was quite clear when I checked the dipstick. I think I may be a bit above the recommended level, but it's at the same level as the fluid that was in there since the car was new.
When I first took it out on a test drive I thought I noticed a little difference in response, but I am probably imagining it. The occasional weird sounds on acceleration from a stop are still present.
In case anyone is interested, I used Centric 120.42091 premium brake rotors and Akebono ACT815 brake pads. I have the 2008 Nissan Versa SL without
ABS. There were no issues installing these items.
Edit: Checked under the car this morning for any leaks and everything looks clear.
