2014 ES, early production number Mirage and it is doing something strange in the CVT. It happens with a light throttle around 46-49mph, or 56-59mph where it is trying to lower the RPMs and I hear this screeching sound along with the CVT jerking and if I let off the throttle it goes away. It is not consistent in doing this, just this morning coming back from the store accelerating from a stop with a light throttle it did it even at a lower speed.
It goes away when I reset the battery (30 minute hard reset) then it comes back. I changed the cooler filter and CVT fluid with OEM liquid gold about 3000 miles ago. I am going to be doing the pan filter and a fresh fluid change this fall as I have all the parts. Thoughts?
