My Car

Question by Rosiew00425 posted 1 year 2 months ago in 2013-____ (B17)

I have a 2014 Nissan Sentra SV with a CVT. Since having the car I experienced random bucking. I took it to the dealer and was told it was normal. Now years later the transmission failed. I have recently had the transmission rebuilt. The shop has had it for over a month due to locating parts. Now they put the rebuilt transmission in and say they are getting a code that a sensor is malfunctioning. This is cause the speed to read incorrectly. They said the transmission is running faster than the odometer is reading. I have put a lot of money into this repair and to me it seems that they are guessing more than knowing for sure what the problem is. What could be the issue?
