You're replying to a 9 year old post, I don't know if any of the posters will still be listening.I've called the dealerships near me for a quote and what their CVT service actually entails. After explaining it all to me I asked well what about the CVT filters? And he said and I quote "we do not change filters in the CVT transmission they last the lifetime of the vehicle"..... Idk about you guys but I've never seen any filter of any kind last for the entire lifetime of any vehicle lol.
FYI, the reason Nissan doesn't recommend changing either filter is perfectly sensible. First, CVT's have almost no clutch material and never make "ATF soup" like a regular A/T. No matter how decrepit the fluid gets, it only oxidizes and forms varnish. It never gets soupy because it lacks the ingredients. That's the reason the primary filter is a screen and not a true filter, and it's easy to blow it clean if there's any visible debris. Changing it is a waste of money. The paper element under the beehive is there only to catch fine break-in shavings, and it pretty much does nothing after break-in. Shavings that occur after that are almost always larger and the magnets catch them. Changing the element entails possibly putting some of that fine stuff back into circulation, so Nissan recommends leaving it permanently alone. I agree with both recommendations.
Now, your 30K changes -- all I'll say is kudos. If everybody did that, the CVT's reputation would be sterling and not suspect.
