Your Transmission is covered by a 10 year or 120,000 mile warranty - whether you're the 1st, 2nd, or 3rd owner. That's 100% parts and 100% labor. Bring it by a Nissan dealership to get checked out before it gets worse.

I had a similar issue in my 2012 altima 2.5. My symptoms were that when it was hot (90+), on the highway I would find myself stuck in 6th gear and unable to shift down or up. The car would shift with a change in speed, but barely enough to get off the highway to park (ie, it was always 1 gear or so above where it would have normally been). Stopping and turning the car off might fix for a little while. I took it to the dealership and they said the problem was that the transmission fluid was overfilled by as much as 2 qt. I've never done it or had it done, but Firestone (who does my oil changes) must have "topped it off" for me. Luckily they used the correct fluid or I would have really been screwed. This may be only one of many causes, and I don't know how to correctly gauge if its overfilled or how to resolve it, but that was what the dealership found. I recommend taking it to a dealership to get checked out over doing it yourself but its one possibility.

For no reading fail code case, the CVS fluid might be low or overfilled. However, the transmission temp sensor could register an overtemp limit; therefore, make sure that the radiator coolant system does its share in cooling the CVS fluid line (50/50 mixing if using concentrated coolant).
