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.
Any noticeable smoking gun?
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.Quote:

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?
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).Quote:

Here's what the backside of the input housing should look like Attachment 11440 There is a shim and a cheap looking thrust washer that just sits there loose between the shaft and the housing. Attachment 11441 Attachment 11442
And this is the crack I get to attempt to repair...Attachment 11443
Sure hope the drivers are ok.Quote:

This is cause for concern for me. I love my Fiats but my main complaint with them is the lack of parts availability. God forbid you need anything quick as most parts take a week or more to get. It's the main reason I probably won't buy another. If this is an issue for Mitsubishi, I may need to stay away.Quote:

Just interested in everyones thoughts; does this increase the risk with the cvt? Or fairly safe to buy and immediately change that fluid/filter? I know there are no guarantees, just curious what the wisdom of this forum thinks. Thanks in advance!
Hey Fummins,
Curiousity here...since the thrust washer seems to be the weak link, would more frequent fluid changes really change the outcome? Seems to me it's just a cheap part or bad supplier. The heat of frequent high speed travel could also be what's degrading the part faster, meaning a city driven Mirage may have better luck. I know the 4 speed automatic on my 2010 Accent (which was used on Mitsubishis) was known to have poor cooling capabilities and suffered on long highway drives. Around town it would shift fine all day, but drive it on the highway for an hour or more and when you got off the highway, it would sometimes slip like crazy and shift harshly.
This thrust washer experience also reminds me of VW's short-sighted move to remove a simple c-clip from their short ratio 5 speed manual in the early-mid 80s in order to save pennies per car. The end result was the transmission earned a reputation for throwing 5th gear off the shaft between 100-200k. It was guaranteed to happen to every tranny like it, regardless of fluid changes. Happened to my 84 Rabbit GTI while going 70mph. I pressed the gas to accelerate up a hill to pass someone and the revs just shot up as if I was in neutral. I was steady losing speed and only got grinding noises when I tried to shift back into 5th. Once I pulled over, calmed down and called dad to find out what to do (I was on way home from college), I discovered the car would still drive fine in 1st-4th gear. I give the car credit as I limped her home at 60mph in 4th for 3 hours.
I would expect that publishing a service interval that is more frequent than others becomes a deterrent to either sales or the service requirement.Quote:

My 2 cents (.026 Canadian) on the cvt failures: have we heard anyone else that isn't a delivery vehicle talk of failures? It does sound like the thrust washer may be a weak link, but I wonder what role being on the road all day plays, other than accumulating mileage faster?
A commute gets her up to operating temp, then it sits for 8 hours, cooling down to ambient temp, and repeats on the way home. A city car MAY get up to operating temp, but won't stay there for sustained periods like your delivery cars. Either way, it still shouldn't fail, I'm just wondering if the sustained operation is the X factor, with an eye toward insufficient transmission oil cooling? Does the mirage have a sensor/light or throw a code if its exceeding operating temp range? Or maybe ( more likely), that part isn't built to withstand the operating temp specifications. Just trying to hypothesize...I used to be a Honda tech in a previous life and I enjoy the post mortem of figuring out exactly what failed and why. Thanks again for all your posts; hope we don't lose you if your company switches to a different brand of automobile!
And this, ladies and germs, is precisely why I held out for a 5MT. I know a clutch will be needed at some point, no big deal as I've done a few on Saturns and Fords.
That's got to have 250,000kms on it. Otherwise, why brand new brake pads, shoes and tires? How the hell do you roll up 250,000 in a year or so?Quote:

I wonder what the 2017+ roller cam looks like. I don't recall seeing any pictures of one yet.Quote:

Where's the MIVEC?
Pics rotated .. better view.

That is much simpler than what I expected. There's no 'swing cam' complication as shown in this video:

Now I wonder what's in that there little can...
Also it looks to me like the cams are pressed on.
It must work more like this:

I'm wondering if the cold Canadian winters are having an effect on the CVT's long term. There is this warning in the owners manual. Even though temps may not be -20C, they may be cold enough consistently enough to create some excessive wear due to lubrication issues.
Startability of continuously variable transmission(CVT) vehicles with an ambienttemperature of -4 °F (-20 °C) or lowerWhen the ambient temperature is -4 °F (-20°C) or lower, it may not be possible to startfrom a standstill even with the selector leverin the “D” (DRIVE) or “R” (REVERSE)position.This phenomenon occurs because the transaxlehas not warmed up sufficiently; it doesnot indicate a problem. If this occurs, placethe selector lever in the “P” (PARK) positionand let the engine idle for at least 10 minutes.The transaxle will warm up, and you will beable to start normally.Do not leave the vehicle during warm-upoperation.
Hi, I am trying to find more info on the 2013 90.000km Mirage CVT transmission but I am not able to view your attachments. Any chance you can send these directly to my email? Have just started to notice the warning indicator comes on the dashboard and it sometime seem to slip when going uphill. But mainly when the engine gets very hot. We are located in Sydney Australia where the temperatures can reach 40 degrees! So any information that may relate to this would be appreciated. Tx
