Thinking about have my local mechanic do this. He’s very good and trust worthy. He did my brakes when I bought the pads from Nissan.
Does anyone know what Is required/done for this so I’m informed and can purchase the right stuff? I vaguely remember something about a gasket, filter etc.
I doubt anyone but a good dealer is qualified to rebuild a CVT at this time. In fact, my impression is that dealers replace CVTs instead of rebuilding.
Most mechanics will not warranty work if you bring your own parts. You can ask if the mechanic has different levels of parts but I would just let the mechanic take care of it.
Take it to the dealer. Usually they aren’t that bad as far as cost on tranny service. CVT need special fluid. Too many people say they got their transmissions ruined by the wrong fluid. Not worth the savings.
