    New 2020 article about the JATCO CVT7, its good and bad.

    https://www.transmissiondigest.com/t...lematic-cvt-7/

    An insightful but alarming 2020 article about the JATCO CVT7. The author mentions some positives but also mentions a couple of severe design flaws. Having to install a new CVT cooler every 30k miles as well as fluid changes gets very expensive if your racking up serious miles.

    "Either way, it is recommended to install a new heat exchanger every 30K to extend the life of the fluid and transmission." Jeez whats the cost of that?

    He didnt mention anything about torque and hp though or stress levels so its kind of ambiguous.

    Ummm...this is the same article you linked in this thread 2 weeks ago:

    New confusing article on the JATCO CVT7

    If I owned a CVT Mirage, I'd find something to monitor the CVT fluid temperature. Then you would know if/when the fluid is overheating (usually the first sign that something isn't right in your transmission).

    Look into an inexpensive phone app that might be able to do it with one of those bluetooth dongles...like this video shows.

    I would tell you to get a Scan Gauge, but I'm not sure their XGauges functions (required to read CVT temperature) work on a Mirage.

    Is anyone monitoring their CVT fluid temperature?!?

    Has anyone with a CVT done this yet?!?

    I thought the bluetooth dongles were to be avoided on account of finiky Mirage electricals? If not, Ill look into it no doubt!

    Some of them can cause issues...but not all of them do. If you get one for $0.99 at Pep Boys and the instructions are in Chinese, then you may have issues. So try to find one with good reviews. Just be sure that if you buy something, it can monitor the transmission fluid temperature sensor in a Mirage.
