I have footage of the owner's manual from a 2008 Altima here
https://www.youtube.com/watch?v=-JByqE-CSU4 and it doesn't even list the capacity for CVT's!
Mine took 7 quarts of Valvoline brand CVT fluid (listed as NS-2 compatible). I loosened the CVT casing's bottom pan and let the old and dark CVT fluid gush out. I still don't know what the official total capacity is. Yes, I drove the car around afterwards. The only noticeable change was that the slight whining from the tranny during "manumatic" shifting is now gone.
