    Burnt CVT fluid at 30,000 miles

    Greetings. Just did my own CVT service. I have a 2017 Mirage G4 sedan, with CVT.
    I live in Las Vegas where temps can easily top 113-14° for 2-3 months during summer. Just recently the CVT started acting strange. Slow reaction times, jerking at low speeds.
    Dealer said I should do a CVT service at 30,000 miles. Dealer also wanted $329 for the service. Well, I decided to do it myself. I bought the external filter, O-ring at the dealer. Bought four qts. Amsoil CVT fluid.
    Imagine my surprise when the original fluid came out brown....
    I dropped the pan, cleaned the two magnets, and cleaned the metel screen.
    Popped in a new filter and O-ring. Refilled with Amsoil CVT. The CVT feels like new again. I actually feels a lot smoother, better than it ever was new. I documented the entire service with pics and video for warranty purposes. I'm not an Amsoil Distributor so don't flame and troll me LOL. I just wanted to pass along my personal experience with the CVT service and the marked improvement in feel and drivability.

    Cheers, 3banger

    If you have some of your old fluid available, it might be worth $28 to get a Blackstone transmission fluid analysis to tell you the real condition of that fluid and any contaminants that are in it.

    I second that. If you have any concern about problems with your CVT it can be found in an analysis, and is a small price to pay to better understand what's going on.

    Thanks for sharing your work.

    Thanks gentlemen. I did save a small bottle of the dark brown CVT fluid.....looks like Guniness LOL.
    It took me a while to find the freaking external filter. No pics anywhere on the net showing location. Couldn't call the dealer because of Labor Day. It wasn't really a pain in the a$$ to do, just took a while, about 4-5 hours between scotch rocks.....

    This is a stupid question...but does CVT fluid look like "normal" red transmission fluid when it's new?

    The fluid I use is brown. The factory stuff is pretty dark too with a greenish blue tinge to it.

    For anyone else looking for the cartridge filter it's on the lh side of the cvt rear of the dipstick tube. Make sure you double check the fluid level once it's good and hot too.

    Here's a few links I just stumbled upon that kinda show where the one filter is. https://mirageforum.com/forum/showth...t-fail?p=74296
