Actually mine doesnt seem to have the lag as much as it feels a lot less aggressive than it originally did (with the old s/w AND the new s/w)

For example, coming out of a turn with the engine at 2500RPM or so, if you gun it it doesnt shift down it just kinda takes its time getting up to 3000RPM then it takes off (without a downshift....just once the engine gets into the powerband it accelerates better)

Its almost like its not downshifting when it should, which I guess could be considered lag, but since it NEVER downshifts its not like its waiting too long to do so.

Ive tried the reset and it seems to work a little better for a while then goes back to its old ways. Even after a reset it NEVER works as nice as it did the first week or two after the new flash. Ive been resetting using the "press gas pedal" method, have never tried disconnecting the battery.

 

I found that you really need to be a little more aggressive with the Go-pedal than with other cars. Probably for MPG goals. Move the pedal a bit more and it will drop down a gear or two. My foot got used to how much pedal movement is needed. It took some getting used to.

And honestly before the 027 reprogram I was so disgusted with the trans, that I refused to try to get used to it, which made it a really miserable ride. So it took some faith on my part that it would work well once I got tuned to it. Now of course, I can not say that your car is working the same as mine, but really once I got used to how to "talk" to it, I found it so much more satisfying, and I was able to build my "skill" at giving it just the right input for the desired result. Some people will probably chime in here and say "hit the paddle if you dont like the gear it is in". And that's a fair remark because the paddles are there for a reason. I use the paddles FAR less than I used to. Sometimes I don't touch them for the whole drive.

This transmission's programming works more on "predictive" behavior than it does on instant reaction to tiny Go-pedal inputs. It seems to look at braking rate, speed, wheel turn rate, vehicle rotation rate, and decide what gear would be good to be in on the exit. I actually prefer something that simply responds to small pedal inputs instantly, BUT I have gotten used to this one being in a pretty good gear coming out of turns, automatically, which is itself pretty nice too.

I probably turn more aggressively (more speed and braking coming in) than most so maybe it is downshifting more for me and in a better more aggressive gear exiting the turn. If you don't like the gear it is picking, then yeah it probably feels stubborn because like I said it takes more throttle change to wake it up than other transmissions.

What I would try is get on the pedal a little more than you usually do, a little sooner than you usually do and you may find it reacts sooner and better. I don't understand the learning aspect of the trans, but this may help it to "learn" too. Works for me anyway.

Note to self: I use "quotes" too much.

 

Funny thing is sometimes it drives like a *aped ape.

I managed to find every patch of black ice last Friday, the car drove like it had a million HP. Breaking the tires loose left and right.

This morning, what I felt to be the same throttle input just kinda acted like the car was falling flat on its face. Makes me wonder if its adapting, and if so how fast/long it adapts for. If I hammer on it from a dead stop it just accelerates like mad, but if putt off a red light it doesnt want to respond as quickly to further throttle input.

 

Just drove it again.

What Im noticing is:

Driving along, if I want to accelerate (either after being slowed by a car in front of me or just want to go faster in general), if I dont really lean into the pedal the RPMs will jump up a bit like the torque converter unlocked, then they will lower back down like the converted locked again, then if I had given it just enough throttle input it will actually downshift. Without just enough throttle input I just get the unlock, lock then the car accelerates slowly without downshifting.

This mimicks mostly how the car acted *before* the latest update (note I got it right after it came out, so its not the D version if anything is different). Oddly enough this is also how my Frontier works....give it gas it jumps up a couple hundred RPM, comes back down, then if there was enough throttle input it will downshift.

 

^^^ All nissans do this in my experience.
I'm pretty sure the converter unlocks when coasting. I am also pretty certain it stays locked when coasting when you're in manual mode. Some day I will get a Consult tool to monitor everything. So the brief rise in rpm is the time between throttle application and full converter lockup. It has to "ease" it in.

But if I give mine more gas it drops down one or more gears, depending on how much gas I give it. It just takes MORE gas application in this car to provoke a downshift than in other cars. And I'm ok with and have adjusted to that, personally.

There's initially maybe a quarter second delay between application of gas and getting a downshift. I do not call this "lag", just a brief time when it decides what you want it to do. My G35 5AT was the same in that respect. I consider this acceptable, albeit not ideal.

The "lag" we were all carrying on about, in previous software (075 I think) was the long delay after coasting to about 20mph, where the gas pedal would have no effect whatsoever, for a whole second or more, while an 18 wheeler was coming to T-bone you. That thankfully is completely 100% gone and has never ever happened since 027.

 

Yeah, its odd that I didnt really notice it the first week or two after the 027 flash. The only thing I can think of is that I was "hard" on the car trying to get it to have the same issues as before, and the car responded to me being aggressive with it.

Since thats not sustainable around here (give it full throttle and within 6 seconds you are tailgating someone), it might just be that it "adapted" to the putt-around-the-city lifestyle that my car lives 90% of the time. I might still take it to the dealer if they dont mind taking a look at it. I need new air filters and a tire rotation so maybe that can be my guise for dropping it off

 

Is there a menu option to see what version you have similar to checking the map version?

 

Hey Chris11LE, Let me chime in.It's been awhile for as you guys know, I was a "chronic" complainer about the 7AT. Chris, you had the 027 TSB reflash applied as you have posted. I found similar results to yours, but a little more erratic. Since late June or early July, when I had the reflash done. At times i felt the Lagging and other erratic behaviors return at times. Try driving in DS mode for a week or so, in all driving scenarios , eeven use the manual mode some more as well. Since I did that, and now drive it almost exclusively in D Mode, she feels more like it should. More responsive upshifts, less quirky coasting, especially in stop and go traffic. I have not Reset the ECU (battery disconnect or otherwise), but followed this policy. I am more happy with my G now. But will only give the 2014 serious consideration at lease end this summer, Only after taking the new one for a good long test drive. Preferably for a day or more....I would be looking for a bit larger car for at 61 years old, over 200 lbs, the Personal Sports sedans are getting a little weary. I could use more room - like the M or The Buick LaCrosse, or Lexus G350, or even the Acura TL.....man the Audi A6 Quattro with the 3.0 Turbo is really winking at me, but my wallet is "burning" every time I see the "winks"....ha,ha.

 

Great write up. I totally agree....this car drives much better if you squeeze the gas pedal and keep pushing slightly. It doesn't accelerate well using a minimal throttle application like I've used on every car before this one. Other cars will walk away from you if you just give it minimal throttle. It's a little weird getting used to it, and personally, it's more interaction than I want some days after a long day at work, but it does work.

 

I will give that a shot. Whereas I remember a few people saying DS didnt seem any different from D initially after the flash, I can definitely see a difference between the two right now: DS seems more aggressive than D at this point. Maybe not perfect but definitely more aggressive. It makes me wonder if, during the initial period right after the flash, what we were seeing was D acting more like DS, instead of the reverse.

As far as the '14, have you seen Jalopnik? Im not sure if they are 100% accurate but they had pics of the "new G". Infiniti is calling ALL of their cars "Q" (so no more G, M, JX, etc), and then some numeric code to signify (no longer the engine displacement). The "new G" is going to be the Q50. If the pics they have of it are correct, they are clearly trying to mimick the front end of newer Lexus vehicles (with the "sideways V" in the center of each side of the front grille). I am NOT impressed.

Chris, I agree with the front grill looking Lexus like (the Altima and Maxima has similar characteristics), but it also resembles the new Jaguars too. This seems to be the current trend with many car makers. But overall, I like the initial looks at the new photos taken on the 2014 Thread. But to me the real variable will be the drive train. If it's the same old 7AT (with the quirkiness), that could be a Deal Killer for any consideration by me at lease end in August.

 

The prelim specs show same engine (VQ 328 hp) and it says 7AT, not sure if the same or different, it appears to be the same.

 

I think they had a chance to make the G as relevant as it is today, if not more so. But if the pics are an indication, I dont think they took advantage of that chance.

Is '14 the full redesign or just a refresh? The funny thing is my favorite part of the M is the back end design which looks like the same thing they did to the back of the '14 G.

And I agree with Almatti, if they didnt fix the 7AT and threw it into a new generation, well thats just about what Honda did with the Accord and TL about 10 yrs back. I dumped my Accord as fast as I could, still living with the wifes TL but it will be replaced soon. Was hoping for the '14 G but now not so sure.

Awful lot of questionable design changes/choices/decisions being made out there today. The new Vette now the new "G"....maybe they know something we dont but right now I dont have that much faith.

 

If you look at the 2014 Thread and the recent comments there, about BMW & Altima comparisons... It's mostly about the design. Notwithstanding the design similarities of the Maxima, the new Lexus' , evne the newer Hyundais, it comes down to the "drive"...

Chris, and many other of posters about the now notorious 7AT, will continue to ponder the decision of anew 2014 G due precisely to the 7AT. The 2014 thread postings also relate to "tranny" problems with other Nissans. I had a 2005 Altima, that after some mileage over 15K if I recall, it started to develop Torque Converter problems (very harsh upshifts at 2-3, quirky and ineven coasting in highway traffic scenarios [20-40 mph]. Nissan replaced the valve body, but my local mechanic always insisted it was the TC not the valve body. I had been close to the end of the lease on the Altima, so I let it go. Then I leased and upgraded to 2007 G35X. That Tranny after 18k miles or so was Replaced under warranty (The dealer had earlier replaced the valve body too!!!). With the new tranny, the sometimes harsh 2-3 upshift was smoother. I should've bought that car at lease end, but that's another story...
It seems to me that JATCO makes the trannies for Nissan and Infiniti. JATCO=Japanese Automatic Transmission company. I'm not sure if they make trannies for any other car maker in Japan. But from my experiences with these 3 Nissan products [The Altima, 2007 G35X and now the 2010 G37X], it appears there are problems. Oh Yeah, had a 2001 Pathfinder, after 130K miles it developed warped gears in the front transfer case, but that may have been the result of my son's misuse of the 4WD system or a mechanics error when he changed the Transfer Case's fluid at 80k...The drian plug was "locked-frozen" into place. They used an aluminum plug into a steel transfer case...BTW< the Pathy was terrific vehicle but of course, sucked gas like a Banchie..

 

I have an '01 Frontier so I know about the "sucks gas" part. I cant quite figure out why such a relatively small V6 gets such horrible mpg! But, at least the tranny works

Automatic transmissions are the one thing that I cant quite figure out....have they EVER been perfected along the way? Manufacturers barely get a 4 or 5 speed model working, and then move onto a completely different design to add more gears. For what, 0.5 MPG extra? I can understand the whole marketing behind saying your car is more efficient, but at what cost to the customer?

Im really vowing that my next car will be a manual shift (I dont care how many gears it has.....3 or more is fine for me, mpg be damned!) Its just massively inconvenient because the wife cannot (and has no desire to learn) drive a manual.

So the other option is to buy a car based on the reputation of its transmission. Sorry, thats just not me....I want a car for the design and how much *I* like it.

Id have to limit myself to something like a VW/Audi because their transmissions are great (kind of....my brother in law is dealing with a slipping tranny in his 02 Jetta with 130K on it....but the tranny is not user-serviceable so get ready for the bill!), but only if the car doesnt burn down from electrical issues

BMW (and maybe Mercedes, havent checked) transmissions are excellent too, except I don't like paying for the "privilege" of owning one not to mention the out-of-warranty issues that always seem to pop up.

Really kinda narrows it down to the Jap cars. I refuse to buy another Honda product (go figure, because of previous issues with their automatic transmissions). I guess the only thing left is Toyota/Lexus. Havent really looked at them because all of their local dealers are part of this massive family owned thing. So pushy that I didnt even finish parking my old car before they literally opened the drivers door and asked what they could sell me.

I think we should all just go back to the TH350 or TH450 that GM made back in the day. Bulletproof! I think they still use some form of the TH450 today in their vehicles. But alas it only has 4 speeds so no one can brag.
