7A Transmission...dare I commit heresy?

Dark Sarcasm · 12-08-2011, 06:05 PM

mines shifts in corners, braking, whenever i ask it to.

Yeah he's referring to this quote from WWJD:

Quote:

The tranny is no good for racing. It wouldn't shift when the car is corning, or braking. The only way you can down shifting is when you doing northing with the car. SUCKS!!! Hopefully someone come out with some tranny software tuning.

I donno, I guess we could talk to WWJD and try to get more info about what issues he was having, but I assure you the 7AT is meant to shift under all reasonable conditions, including while braking, cornering, and/or accelerating very hard. I'll link my track video clips again, where you can clearly see my 7AT doing all of the above in various places (well, I try to avoid shifting while actively turning a tight corner so you won't see much of that, but it does in fact do so just fine): TDE MSR-Houston Nov 6 2011 - YouTube

He may be referring to the fact that it will automatically downshift if the revs drop below 1.5 K.

I find that mildly annoying too, but you can downshift before it happens and if you don't, we'll then you are in the right gear for when you plan to accelerate out of the corner, so it all works out.

It's a minor issue -- basically you can't really be in the "wrong" gear as revs drop. Otherwise the 7AT is pretty much perfect.

Anybody know whether the GT-R does that too?

wstar · 12-09-2011, 06:13 AM

Don't know the status of the GT-R or other PDK/DSG-type transmissions on the automatic downshifts. However, on our 7AT it's really more of a help than a hinderance. If you're actively managing your downshifts you'll be hitting that button way before the TCM does it for you. The TCM downshifts at a pathetically low RPM just to prevent a long-period loss of lockup (or for that matter, engine shutoff eventually) due to low RPMs. If you're not actively managing downshifts (e.g. coming down to a red light in normal everyday street traffic), just let it do its thing and it'll keep you in the right gear for a very mild and fuel-efficient takeoff when traffic starts moving again

That's how I see it too, and I'm fine with it. I have had other semi autos that didn't down shift until you were at about idle, and then it went immediately to first -- I liked that better, but I can certainly accept this.

ImportConvert · 12-09-2011, 06:20 AM

I agree. I tested if it would downshift or kill the car or buck. I liked that it does that. I imagine without the rest of the stuff ( stick and clutch) going on a lot of people would forget to ds and kill it often.

I have just not had good luck with autos, but if they find my car 100% as I want it except in auto, I might consider. I just have never seen a reliable auto, and do plan on keeping the car long term. I have owned 3 autos so far. Killed em all, or at least had them slipping on hot days. Never killed a manual.

Dark Sarcasm · 12-09-2011, 03:34 PM

one thing reason i like a manual over the auto is being able to push in the clutch and coast in nuetral. other than that i will take the 7AT. Its a perfect balance for those of us that want to be comfortable cruising and switch to manual mode to have fun also.

b1adesofcha0s · 12-09-2011, 03:41 PM

I wish they would put the GT-R's DCT into the next gen Z, that would be awesome

sonic370 · 12-09-2011, 08:46 PM

Well this ain't your grandpa's slush box PERIOD...
Has anyone driven the mustang or camero AT. how do they compare?
i'll stick my neck out say they don't, close but not quite....

imho it comes down to personal choice were all z owners here
so we all win...............

iv'e owned both but it was the paddles that sold me just had to have them!!

I'm not sure on the camaros or mustang, but when the vette came out with the 6a, it was within a tenth or two of a second with a pro driver on the same track or something rediculously insignificant to anyone but a magazine article racer.

ImportConvert · 12-10-2011, 06:28 AM

All the horror stories of the manual still have me considering : /

Just a vocal few, or what? Seems like damn near everyone here with a manual has a grinding issue.

wstar · 12-10-2011, 08:11 AM

Really the reason I stand up and advocate the 7AT so much is because otherwise it gets **** on a lot just out of the general "sportscars aren't autos" mindset, and it's a fine choice

. So that aside keep in mind they're both fine options, the car rocks with either one, and there's a long list of minor perfectionist quibbles people will make about both of them. I wouldn't let that list stand in the way of a decision though: just pick what you're gonna be happier driving

.

Is be much happier with a manual...if it doesn't grind. :/

Just read...traction control is not defeatable with a7? NO burnout possible?
