Hi, I have a 2017 NV 2500 and I had problem taking off slow the transmission would like over shift. It would be in 4th gear going 20 mph. I took it to dealer and they said there was a computer problem and they downloaded new software. Still drives the same. I hate the van because of how it shifts and if they don't have a fix for it I will Never buy a Nissan product again. I'm a Toyota guy all my life and Never had a problem.
