    Cvt failure at 223000kms / 138k miles (courier car, 2nd CVT failure in the fleet)

    She's toast Attachment 11413 Attachment 11414

    I'll bet the same problem as the other car:

    Thread: CVT Failure (at 304,000 km / 189k miles, delivery vehicle)


    I'll be tearing it apart once it's out. No engine lights on at all.

    Was it driven hard?

    If my CVT goes to 223,000km, I'll be happy. At my current rate of driving, my car's CVT should then last 60 more years!

    Fummins: Since you’ve had a couple of these apart and are now doing filter changes along with fluid changes is it possible to change the upper cartridge filter without draining the pan? I understand there’s no way to avoid that with the pan filter but was curious if it was possible with the upper one.

    Thanks for all your expertise and data. 2 same failures around the same mileage in your fleet is looking like a trend, which is sad. How much is a rebuild or re-man cvt costing you? Anyone on the forum have higher mileage cvt without failure? Maybe we could deduce driving conditions might factor in? Although, from what I've read, you are very proactive with maintenance. Really wanted the automatic, but leaning toward the 5 speed with this new info...

    The first CVT went at 304,000 km / 189k miles. This one is significantly earlier.

    The good news is that there will probably be a healthy supply of Mirage CVTs in salvage yards in the future. Let's face it...if you look at a Mirage cross-eyed, it's almost totaled. This CVT unit is also used in multiple vehicles.

    As long as you aren't relying on Mitsubishi for a replacement (around $4K the last time I looked)...or AAMCO...you'll probably be fine if/when you do need a replacement.

    I remember you posted these were highway cars for the most part. The original plan was to pick up a used Mirage, use as my commuter, then turn over to my youngest in 4 years for his first car. But, I average 17000 miles a year just on commute miles, and if I get anything with 45k + on the odometer, I'm turning it over to him in what is looking like the cvt failure window. I do think it will be a great first car; not like the torque steer is going to jerk the wheel out of his hands, lol.

    What did you end up doing with the first car with failed CVT? Did you throw in a used one?

    Of course the piece that is cracked is main case.
    Aluminum brazing rod assuming you can get the crack cleaned out. I was planning on using it for a transmission case mod I had planned on another car. Worked great for a oil pan repair on my sister's TDI. This was my first go at using it (besides the tiny patch you see on the left).
