I just got a 2012 G37 auto, and every time I floor it the shifting is super delayed it’ll shift but the whole car will jerk and it won’t catch gear till about a second later. Normal driving everything is fine it’s only when I floor it. To get around the huge jerk I drive it in manual mode and lift off the gas when shifting like it’s a stick then floor it again after a second and I see it catches gear. It does this from 1-2 , 2-3, 3-4. Anybody know how to fix this?

 

The auto is just jerky in general tbh. I had this issue on my 2013 G37 and 2011 G37xS. Nissan is known for crappy automatics. You can try to do a drain and fill on your transmission fluid to see if it makes a change.
