nah far from moving on. Sensor issues not mechanical, if I am reading the situation correctly. Or calibration.
2010 was the first model year so bound to have a few issues. This could be tss/oss, but if it was acting like it was in neutral, then it COULD be the trans range sensor. I would do them all at the same time as they are all packed in together, if it came to it. 4 hrs labor.
