I have a 2010 Nissan Altima that I had to have the transmission replaced April 2018. It came with a 12 month 12000 mile warranty. Since then, I have had to have it replaced 2 more times. The 3rd tranny started whining so I took it to Nissan, they said the tranny fluid was Overfilled and causing it to overheat. They adjusted the fluid level but said the damage may already have been done. It seemed to run fine. Last week it quit and I was stranded on side of road. Had towed to dealership and they confirmed I will need a 4th transmission. However the warranty is only from the first trans put in and it is now 2000 miles over warranty. Trying to decide if I have a case?
