About 8 months ago i noticed when i put my car in park i hear a pop and can feel it through the shifter, somestimes if parked on any kind of incline it will roll and pop ever louder and feels worse. So i took it to the dealer and they did not know what was wrong with it, they called nissan and luckly i got a new transmission thanks to the warrenty. Well hear i am 6 months later and its starting again, does anyone know whats causing this and how to fix it? Has this happened to anyone before? Any advice is helpful.

Thanks

 

anyone know?
