Is it viable to install a Magnefine in-line filter on a CVT transmission? As far as I know, a Magnefine's restriction to flow is negligible (as tested by Ford), so I don't see any reason not to install one. The cost of some CVT fluid to top up is exorbitant, of course, but other than that...
My mother's 2007 Altima has 90k miles. The Nissan dealer said there is no need to change the fluid yet. They checked several thousand miles ago, presumably by determining the fluid's deterioration level via their CONSULT III scan tool. I am thinking of getting a flush done once it hits 100k just to be on the safe side, so I was wondering whether installing a Magnefine would be viable as well. I know Nissan extended the warranty for CVTs to 10 years/120k miles. Installing a Magnefine would probably void that warranty, so maybe my question is a moot point (at least until the warranty expires).
