When they first appeared I looked into them and it's like two wedges/tops with special belts. They slide back and forth unto each other to give you the infinite gear ratios. I was like ha no way am I messing with those. The fluid must be changed right on time to avoid a blowup and it's a fortune. I had a truck so it didn't have those. Even that I had to reroute the coolant line because of dumb shit they did, routed through the trans and it cracks and you end up with coolant for transmission fluid, which destroys it. Dumb!
I've driven a few CVTs, it was like an infinite slushbox of no-go. That's why I bought my last car as a stick. Those seem to be vanishing, sadly. Gotta have that nanny driver system in your car!
Automatics use the radiator as a cooler for the transmission fluid. I always used to disconnect it and put a simple cooler on the front of the car when I had an auto, probably saved my butt more than a few times.
I didn't even add a cooler, no overheating or nothing after that.
The electronics in the new ones are crazy and with the shortages makes me nervous. Trucks go in for service and just sit for months. They drive great though, power, mpg, smoothness, everything just keeps getting better. But I have been looking to get an old truck as a backup too, something 1970-85 or so.
