It’s basically a complex snowmobile transmission. There are two pulleys and a belt connects them. Imagine a bike that has the main big sprocket at the pedal where your feet are and the back has that cone shaped 3-5 whatever amount big to small stack of sprockets. Sort of like that. By changing the position of the chain on the rear sprocket set you have different gears. This is a basic explanation.

It's not so much that CVT technology is in itself unsound, it's mainly CVTs that are manufactured by JATCO that tend to be problematic and there are a heck of alot of them out there.

EVERY Nissan with a CVT uses a JATCO transmission.

A few other manufactures have used them here and there as well.

There's no way to repair them, essentially consumables with the potential to total your car if you don't have the money to replace one.

Most owners don't change the fluid on these, it adds to the failure rate.



The transmissions are not any more complicated that the regular or dual clutch transmissions, its just that you have to replace the whole unit with a new one which costs a lot.



If you had to replace every/any transmission with a brand new one, it would cost a lot. (As opposed to rebuilding them)

Yep. The Jeep Compass and Patriot had the JATCO Sentra CVT transmission. Those both usually made any top-10 "Don't buy this car" list.


Personally, I wouldn't worry as much about a 2019 Nissan.

This topic has been beaten to death. Car enthusiasts hate CVT's, it takes out the fun factor of rowing your own gears, or feeling the shifts. Some CVT's have simulated shifts and paddle shifters that try to make it fun. The good thing it's a smooth and efficient ride, and you'll get off the line quicker than a manual that's wasting time shifting gears. I think reliability depends on brand, driving habits, and changing fluid when recommended. The Toyota Prius has used CVT's, and many owners have a lot of miles on them without CVT issues. Toyota and Honda probably have the best CVT's. Honda makes their own CVT's. It's not a little rubber belt, it's often a steel belt. If you're coming to a complete stop before moving between R D, and don't beat on it, I don't see why it would fail early.
