I have taken it to 2 dealerships and they say it is "within normal limits". WTF is that supposed to mean. I also had the same 2 look at the 1-2 delayed shift. According to them, that was within normal limits also. I looked at the atf dipstick and it looks a little high to me. Even when it is cold it is at the full hot range. Could this cause a "delayed" 1-2 shift. Hope it blows up sooner than later. Nissan is currently working on a fix for the driveline vibration during acceleration and they are working on a fix.
