I like that this thread exists to keep the conversation alive about transmission oil awareness. If I were to shop for cars today one of my top 10 maintenance questions is "how to access the transmission fluid". Doesn't mean I will change it but I would like the option to do so.That's interesting that Honda has those short CVT fluid change intervals. I have always been worried about the CVT in my wife's 2016 Subaru Crosstrek. There have been issues with these, and Subaru extended the warranty to 100K miles (supposedly to avoid a recall). So I take it to the dealer for the 30K mile checkups so there is a record, but they say it's a "lifetime" fluid and they don't change it. It's almost due for a 60K mile check, and I may insist on a change.
On CX-5's we know is easily accessible without specialty tools and they come a bit low in fluid level from factory.
Another way to look at it is the two sides of the coin you're eventually going to come across. Side A is what the dealership and manufacturer claims (lifetime, every 30k miles, ect.). Volkswagen and their DSG had very strict intervals I recall in that not abiding by them voided warranty. Not sure where that stands today. As a consumer we should know this! Side B is where does the token independent repair shop or better yet Transmission repair shop stand. They are the ones having to repair or replace many transmissions past the warranty period. I would reach out to reputable one in your area for their take on high mileage Subie CVTs. Only drawback is it may take a few years for them to start seeing your specific CVT. The good thing about the skyactiv 6-speed is its the same one used in the US since 2012! Mazda took a page out of the Toyota book of using old by tried/true tech to get the job done.
