Transmission Gear Slipping problems of the 2010 Nissan Sentra

After driving for about 10 minutes, the transmission did not want to come out of low gear. At 35 mph, I was at about 6,000rpms in drive. I confirmed the overdrive off button is not engaged, nor is it in "l", and the emergency brake is off. When it has been cooled off for about 3+ hours, it will drive fairly normal for about 10-12 minutes until warmed up, then it all starts again. Even once it is cooled off, there is a slight drag on power and it will begin to have erratic shifting (similar to a regular automatic transmission slipping) after a few minutes on take off it feels like the parking brake is on, but it is not. The service engine soon light comes on, the vdc control light comes on, and another light that is above the vdc light comes on. Codes p0720 and p1778 were found by a local non-Nissan dealer who checked them as a courtesy for me. Have discovered that Nissan has extended the cvt transmission warranty on certain Nissans up to 10 yrs or 120,000 miles, my Sentra is included among others. . Read more...
