2013 Touring/Sport (7 SP) AT - Idiot Proof??
 

Hi,

I just did a dumb thing with my new 2013 Z. I came around an intersection right turn in "M" mode and forgot I was not in full-auto mode. The trans auto-shifted down to 3RD gear and I punched it. Everything felt great until I ran out of gear and hit the "rev limiter". The strange thing is the "rev limiter" didn't feel like my old 350Z. The motor didn't choke or shut down. It simply held the revs at 7500 and no more. Of course, I backed off quickly and shifted-out and everything seemed OK. Is that motor and AT that idiot proof?? It totally took it in stride. This thing is bullet proof!!

What?
I don't get it

When I come to a slow turn it will not shift down to 3rd, but when I punch it it will stay in that gear no matter what


If you're saying it then auto shifted into 4th, you got shafted... Because that beauty of THIS AT was that it would stay in whatever gear you wanted...

Personally, if you're not going FI, I think the 7AT is wayyyyy better...

So yeah, it's the motor/ECU/trans

When I dyno'd my car it hit the limiter (speed and revs) and coasted, it was nice

What hes saying is it Did just maintain gear, it Didn't upshift. But the motor didn't get bogged down @ redline. It held the rpms.

Oh, well that's nothing new

I'm glad the OP likes the 7AT

When I saw the thread title, I was expecting an OP about how when you are in full auto mode, but think you're in manual mode, and go to upshift, putting it in neutral... :bowrofl:

VRROOOOOOOOOOMMMMMMMM :eek: fuuuuu!! screech, shift, pull away ducking head down..


:bowrofl: :roflpuke2:

My point is, I think the logic Nissan built into the 7 SP AT / motor CPU is amazing. It appears that there is no way to accidentally over-rev the motor when pushing the limits of the gears with the paddles. Full throttle acceleration isn't any safer in full-auto mode if the motor CPU logic simply won't let you hurt it shifting with the paddles in "manual" mode. BTW in manual mode the AT will automatically down-shift based on your speed and eventually downshift to 1st gear when you come to a stop.

I only ever downshift down to 3rd. 2nd and 1st gear downshifts are too jerky.

I downshift that bitch to first when I want to let my prescence known to an ásshole driver

And in doing so we learn of the paradox of Asshole Transference.


:rolleyes::bowrofl:

In any event... Nissan Z engineering rules...

Well if you car was sitting out in the freezing cold for a long while and your event occurred shortly thereafter without proper warm up...

I'd say sir that can't be good. :)

lmao!!!

There are better ways to make your presence known to an a$$hole driver Andrew. lol.

The shifting characteristics on our 7AT's is pretty great. Rev matching is more aggressive than the settings they put in the G37's, and it'll hold gears unlike a lot of other paddle shift autos.

I do wish there was idiot proofing for the slip-into-neutral goof though. I've done that a couple times on both cars and my instinct reaction is to put it back into drive. This sucks because the revs are usually still around 5 k when that happens and I get reminded of my mistake by the subsequent jerk. Can't be good for the trans.

Yeah, I never understood that... Because you can't go into park or reverse at a certain speed...
And my 2009 Maxima would dumb down the RPMs THEN engage...
(Then again, the CVT is way more sensitive and worse for higher power motors)

:iagree:

dont worry OP first week i had mine home i was leaving a red left and making a left turn and my hand slipped and as i was going to smack the throttle in 2nd to get goin i downshifted and redlined 1st real quick lol

the 7AT is a awesome set-up i'm sure you'll love it more and more as you drive

Omg I hate that! when you are in Drive for whatever reason ( 99% use manual mode) and then you "shift up" into neutral and hit the rpms all way to 7k and you react quick and are like wtfff put it back in gear and bolt off hahah

o,o LOL I have to try this out now.

Another thing that I have found that works well on the 7 SP AT is shifting from full auto to manual if you are cruising around town at 40 to 50 MPH. In the full auto mode, the AT will lope the motor down to below 2k RPM at 50 MPH. (Probably for fuel econ) If you slap the shift into manual mode at 50 MPH the trans will select 5th gear and lift the rpm by about 500 rpm to 2.2k to 2.5k RPM and hold the gear. It moves to motor up on the torque curve and removes the "slush from the box"

thought this AT has lockup on each gear other than 1st?

anyway, good to hear the car bounces off the rev limiter. i would be EXTREMELY PISSED if the car shifted up on its own.

That's awesome, I know exactly what you mean, I had a 350 before as well. Haven't made the mistake with the 370, but it's good to know it doesn't bang against the limiter over and over.

LMAO!

My exhaust it deafening at times, like shifting into first at 30MPH, lol


I get a SLEW of ásshole drivers, and I'm not going to lie, ásshole drivers get ásshole things done to them

(Look up my thread on running a red light) or last night 2 guys didn't stop as I was going 50 and I barely missed hitting them and the curb, so I hit the horn, still going 50, got in front and checked to see how my brakes were functioning...

Lockup?


And the fact it sits at/on the limiter instead of shifting/lets you shift into any gear no matter how high the RPMs are, makes me VERY happy

Stupid ISF I have will stay IN a gear buy locks out gears when you downshift
(1st takes you to like 42, but you have to go less than 20 to go back into 1st... You can floor it and it WILL go into 1st itself, but you have no control)

If you hit the limiter on the MT6 , something cuts out and saves the engine from the driver.

So no 4=>1 misshifts of death?

I'd guess a fuel cutoff first.

Nope, that's still bad. No fuel cut or rev limiter can save you if you mechanically over rev it.

But the syncro rev match will scream at you if you have it on, and hopefully you won't release the clutch. Even if SRM isn't on it still shows you which gear you are in, so if in doubt, look at the display before you release the clutch.

Yeah, hopefully you catch it before you let the clutch out. Otherwise you're going to hear a very expensive noise.
