i want a shift light so badly! must be a way to get it in the 09's 7at's. i'm pretty sure they have the physical light since i believe it's the same part as in the manual 09's

https://vimeo.com/131158695 automatic downshift from drive,while cruising at 68...listen for the click/ that's the gas pedal hitting the floor & watch transmission delay a sec before responding (gotta drop from 7th to 3rd while unlocking torque converter) I'm cool with the slight delay: unless yours is doing something totally different- mine has always performed this way since new.

I was having a similar issue where I opened a thread here:
http://www.the370z.com/engine-drivet...ght-stall.html

For the quick and dirty the Nissan Dealership told me it was pretty much downshifting but I was hitting the throttle to hard (yes, according to them even in automatic you can hit the throttle to hard) and so it hits the rev limit and you get that half a second stall with the sound. He told me in that instance I'm about to accelerate hard and I'm around 60 to pay attention to the rev meter and if looks like its about to limit just ease on the throttle and then go back hard on it if I want, or just be in manual mode, or finally he advised maybe I should just go get a GTR.

hahaha get a GTR..... So was he essentailly saying that when you mash the pedal in D mode the engine can over rev just a bit? My issue happens no where near 7500 redline

Well specifically that if it's in D mode and you're cruising around 60, if you just WOT the car thinks you're passing so it downshifts to make you pass quicker, but I guess it's too much throttle to just step on the gas all the way and hold so you should ease up if all of sudden you see it getting near the redline or you will get that half a second stall. :eekdance:

Solution: drive in manual mode. Never had these problems lol

I hope that makes sense...but you can hear the engine go "ruumm' *once...then "ruumm" twice and on the second rev is when it took off... anyone heard of this before? has happened a few times already thanks

Sounds like the ASC doing its job.

honestly OP, i really think your car is okay.

the dealership you went to probably quoted you on some outstanding (and unnecessary) jobs.
