I’ve been having an issue with my 2013 Nissan Versa sv CVT for about 2 months. While driving on the highway the engine RPMs will be abnormally high. Sometimes I notice the RPMs seem to go from 4K to 3500 back and forth. I’ve also noticed while accelerating the transmission seems to be “searching” for the right point. The car will jerk when accelerating and feels like it’s shifting from 1,3,2,4,2,3. (Random ups and downs). While at a stop with the car in drive the engine idles very rough, shaking the car. Sometimes with the a/c on the idle is better.
