I have posted this in another thread but I'll toss it in again here...
How hot does the CVT fluid in a Mirage have to get before the driver gets an overheating warning?
Answer: 137 C (279 F)...
Is that too hot for CVT fluid? I don't know...but I think I would want to know what's going on in the transmission before the fluid reaches 279 F!
Here are some interesting comments from a Fit owner who monitored his CVT temperature over time...
2018 Honda Fit EX w/CVT
I have a Scangauge 2 and the ability to monitor CVT temps. 7+ months have taught me.... The car does have a CVT warmer. Basically a heat exchanger between the engine and CVT. This will bring up CVT temps quicker for fuel economy and my best guess is that once it tries to go over the engine coolant temp, then you could consider it a CVT cooler. That is very loosely said, but the truth is that it works both ways.
So, about the temps...
Southern Indiana Winter, under 20 degrees: The trans almost never gets over 100F degrees with my driving and short trips under 15 minutes. From there the temps creep up very slowly and I believe interstate cruising was around 150 degrees. No interstate hills in Southern Indiana.
Spring temps into the low 70's: CVT acts just like the winter, but add about 20 degrees. It warms up sooner of course, but not a lot sooner.
Summer 85-100 degrees: The CVT warms up incredibly quickly. I know it helps that it's already warmer to start with... With the car running between 185-190, the CVT is usually 195-205. This is interstate at 75mph. Temperature wise, I feel like interstate driving is where it sees the hottest temps and most of my driving is interstate.
