At least the newer Nissan CVT's have a drain plug. I don't know about the older ones. The CVT doesn't use a standard automatic transmission filter but instead a cartridge type filter inside a housing on the transmission. It would have been nice if they'd have just used a screw on filter. There are also a couple of large magnets in the transmission pan that I want to check, especially at the first fluid drain/fill. I've saw a few pictures of those magnets online where they were loaded with metal shavings. I don't know how long it took for them to accumulate that many shavings but, I don't want shavings turning loose and circulating through the transmission.
Years ago I had a '76 Chrysler that after the fluid had been in it for awhile the transmission didn't want to engage the gears as soon as it was shifted into gear. I'd change the fluid/filter and all would be fine for a few years. One thing I really liked about that Chrysler was that they put a drain plug in the torque converter so you could change all the fluid not just a small amount of it. When I got rid of the Chrysler it had 231K miles and the transmission was still fine.
