If you like to drive your AT Z in manual mode, I can see some potential issues with having 9 gears. Take this scenario: you are cruising down a busy highway at a less-than-ideal 65 mph, in 9th to save gas, and an opening in the fast lane suddenly appears, but you have to move fast to get it. Now in manual mode, you have to downshift four times just to get your car into the power band for best acceleration. Not being a DCT, these gear changes are going to take a frustratingly long time in total, by which point your lane change opportunity may be gone.

In fully auto mode, the AT should drop down to say fifth or fourth in one step when you go WOT. But I have no desire to drive in full-auto mode, it drains much of the fun out of having a sports car - something bought primarily for enjoyment in the first place.

It should be possible for Nissan to program different logic into the AT so that in manual mode when you downshift it skips one or more gears based on the current degree of throttle opening. Or have it drop down to the optimal performance gear ratio if you continually pull the downshift paddle for say 1/2 a second or longer. But these options may bring some legal liability issues with them that make them unpalatable to Nissan.

I don't know that it'll be an issue. Even the current 7AT in the Z drops into 5th as the default upper cog if you switch over from full auto (obviously, you can manually select 6th or 7th) at a somewhat higher speed.

Granted I don't know that many folks would see fit to be manually shifting an automatic gearbox while driving on the freeway since you'll almost always be returning to the economy cogs in short order and you're not going to be revving out higher gears unless you're aiming for felony-level velocities.

There are some cars with the option to hold down on the downshift paddle and it goes to the lowest possible gear. It might have that.
The 10r80s the fords and chevys have seem to do fine with double or triple clicks.

It's not really an issue. I don't see the point of using paddles or the sequential style shifters during everyday driving. It's unnecessary. Step on the pedal harder and it'll downshift like what an automatic does. I find these types of shifters very gimmicky.

I agree with you. I just can't get behind using paddle shifters if I don't need to, and I love rowing gears on a manual.

The only time I think I ever use them is to gear down to slow the car at highway speeds just a touch. Or if you're on a racetrack. Then gain, I'd driven PDK 911s on a track and if you put them in Sport+ it's just as good as if you did it yourself.

Having never driven a "paddled" car (other than in a 20 minute FR-S test drive) it's interesting hearing peoples' experiences with them. Sounds like once you get paddles you quickly lose interest in shifting manually with them most of the time, which for me would suck a lot of the "sports" out of sportscar. All of which makes me more likely to stick with a manual.

Yup.

Only time I've known of people to really use the paddles is during racing applications or playing around. It gets old after a bit. I've changed the paddles on my Supra for a better feel if I want to use them, but as St00k mentioned Sport+ does a great job of shifting.
Then gain, I'd driven PDK 911s on a track and if you put them in Sport+ it's just as good as if you did it yourself.
If you really want to feel engaged in shifting all the time, then get a manual.

I've got paddles...on my wife's Grand Cherokee. Those are ridiculous. The only time I have used them is when I accidentally hit one and then I have to figure out how to get back into auto mode. Having the ability to manually select a gear on the shift lever is fine when necessary (downhill, off road, etc.) The paddles are silly in that car though.

All the more reason to buy a manual.
Transmission is one car component that should never be controlled by software, IMHO.

Isnt the 9 AT from Mercedes? Seemed to work okay in their C class econo models. Not sure they use them in C43 and C63 though

Yes, it's MB's design, but JATCO will be building the trans.

And yes, there's nothing wrong with the transmission. It's still in use today in several MB cars, including SUVs. AMGs use two higher performance variants of the same trans. When I say variant though, I been that the basic design is similar to the 9g tronic, but parts are beefed up significantly. Search 9g-MCT.

I tend to agree, I had an 09 Lexus ISF with the 8 speed and it was constantly shifting and trying to find the right gear. Possibly 7 is all that is needed.

You could be right, and 7 seems pretty appropriate, but that also relies heavily on transmission programming. Some do tend to "search" as a general rule, some wander only in certain drive modes, and some just have excellent programming and work phenomenally, always seeming to select the right ratio. ZF's ubiquitous 8 speed is almost universally lauded for being one of the best in the business despite having seemingly too many gears.

Agree, it was a good transmission, one of the best none DCT’s, I just felt 8 was too many gears for more agressive driving, fun car though…

Mods, let's delete this thread. The less we discuss automatics, the better the community will be.

We shouldn't provide a safe haven for people who want an automatic Z.

The less we gatekeep over the transmission type that people choose, the better the community will be.
Definitely. I will also add that as enthusiasts that represent the community, we shouldn't shame someone that doesn't know how to drive a manual transmission (and vice versa, auto drivers shouldn't shame manual drivers for their "slower" cars as that was simply their choice of transmission for any number of reasons). Rather, we should offer to teach those that are willing to learn how to drive stick.

I firmly believe that the more manual cars on the road, the safer the road will be. The extra engagement would arguably prevent people from texting and driving, as well as allow for them to have a better understanding and feel of their car. But people will shy away from learning if they are being told that they are not real car guys or real men because they don't know how to drive stick - that needs to stop.
