If the scan is still showing a bad Crankshaft Position Sensor after replacement, it could be a loose connection or the sensor thet you replaced is bad. Such sensors are known to fail out of the box.
As to the jerking and rpm jump, seems the CVT is missing a beat and did this happened before the solenoid and/or fluid replacement?
I would like to know the exact trouble codes to be able to do some research on the problem. However data on the CVT seems limited so might need some time to get any results.
