I have a 2012 Versa SV. The CVT gave no indication of trouble no shuttering or whining. It just stopped pulling. After getting the car out of the road I tried again but the engine just flutters and the car will not pull. I tried reverse and it pulls fine. I was told to replace the TCM. I did but no good. It still doesn't pull in drive only reverse. Unless you forget to plug the TCM up. Then it will pull strong in forward or reverse. But lots of other things like abs and cooling fan go haywire.
