What are safe CVT temperatures?

[OrganicFoxes]

Currently monitoring my cvt temperatures on a road trip for the first time. My temps seem to stay around 194F to 203F but i have seen up to 205F. When checking the dipstick, Mitsubishi says the "operating temperature is 122F to 176F, should I be concerned? Not sure how to add pictures from my phone so hopefully the discord file links work.

There aren't a lot of Mirage CVT owners who monitor their fluid temps, so the forum discussions on this topic have been limited. I have read on other (Nissan/Honda) forums that you can expect CVT fluid to run roughly the same as the car's coolant temp. For summer driving that number may be slightly higher. You are close to that. Under what driving conditions are you seeing those temps?

Looking at your phone image...



Is that app ^^^ saying your CVT is running hot?


FYI... Nissan TSB NTB13-095c describes potential high-temperature CVT fluid situations as follows:

1. High RPM and/or high speed driving (4000+ RPMs, and/or 65 MPH or more for 1.0 – 1.5 hours)
2. Driving in ambient temperatures of 96 degrees or higher
3. Climbing steep or extended hills for 6 miles or more

Highway driving is what heats up CVT fluid because it represents an extended condition of continuous high engine torque operating the CVT drive belt. That’s why most Nissan/Subaru/etc. owners experience CVT “limp mode” on the highway. CVT “Limp mode” is when the car’s computer detects high CVT fluid temperatures and significantly reduces engine power until the CVT fluid has cooled to an acceptable level.


What has always concerned me about the Mirage is the high temperature the CVT fluid must reach before the warning light comes on. If the "normal" operating temp is 176F, the warning light doesn't come on until 100+ degrees higher than that.

I really want to know what app you are using and what bluetooth adapter do you have?

CVTz50 as shown in the top left corner of his photos is the name of the app.

My Scangauge Eco has that temp gauge and it tells me my G4 CVT gets up to 204F degree. I haven’t seen going higher than that in my usual hilly commute. Im not concerned.

Here's a link to the application, it's on android only and from what i've seen with my devices it only works on 16:9 displays i'm pretty sure.

I didn't know any ScanGauges could read CVT temperature in a Mirage. Did you have to set up a special x-gauge code to get that to function, or did it work right out of the box? ScanGauge doesn't even show the Mirage on their x-gauge support page.

We need someone to put a CVT temp gauge in a Mirage...then drive up through the Eisenhower tunnel at 70mph in the middle of the summer with the AC on. I think it's a 7% grade for 7 miles.

I wonder if there is an MTz50 app for us 5 speed drivers?
