i guess i'll skip this reflash for now.

 

Almatti: does the reflash fix the "flare" issue for you? I see they mention this in the TSB. Thanks!

 

hado: I've seen that mentioned before: "flare". Can you describe this Flare? My problems centered primarily on this hesitation/lag, and the herky jerkiness of the tranny - particularly while in stop and Go traffic - 40 to 20 MPH or so. That's Gone with the reflash, but as I mentioined ; to me - it;s coasting a bit Too Much now, seems to have lost a little - alost an Over compensation for the gear Hunting issue - that's what generally is causing the Jerkiness in thos described conditions.

I wish I couul report what FishmeetFish has posted here after the reflash. He mentioned that his car is better than ever.

 

The flare: the engine rpm goes up (200-500) during 3-4 or 4-5 up shift when the car is warm, e.g. drive it then leave it off for about 30 minutes to 1 hour.

From what I've read, the TSB fixes the jerkiness in stop and go traffic but it's inconsistent whether the hesitation/lag is fixed or now.

 

I never paid attention to this flare until it was just described. I think I did see that this morning at upshifts the RPMS flared up at least 500 RPMS. SOB another thing that I don't think I had before the Reflash.. Oh BTW, my Auto Windows don't raise the windows in Auto fashion since I disconected and reconnected the battery.....

 

Lol Dang, so the TSB doesn't fix anything hah.

On the windows: you'll need to reset it every time you disconnect the battery. I think you need to pull each switch and hold it for some number of seconds. The exact instructions should be in the manual (or in the forum some where).

 

Hado: It did make the tranny shift smoother !! I'll try the reset of the windows later.THX

 

You guys are making my head spin Just when I think I really want this TSB performed I start hearing more negative reactions to the reflash. I guess I've adapted to this finicky trans so maybe I'll just wait a couple more months to get a better consensus. I really don't want to lose some of the good just to get rid of some of the bad

 

yep...i think i'll skip on my oil change next week.

 

Almatti: I did not have the TSB done scared, LOL after reading about the issues with it on here, I'm gonna try reseting the ECU and see what happens. But as far as now NO TSB for me.

 

ANMVQ and Others: Now with over 100 miles since the Reflash, and my Reset of the ECU, driving 'er hard (as much as possible - we had nasty weather here in NY area yesterday), the results have chnaged a little. I guess it is re-adapting since the reflash / reset, but driveability this morning was different:

Definitely smoother up and down shifts in D and DS mode.

Alot less herky Jerkiness in traffic which seems to mean that its finding the right gear when stopping and going. This also relates to the Better "coasting' to a stop.

Seemed to have less lag/hesitation this morning. I take a 40 mile jaunt to work in LI. I really stepped on it today in both D and DS mode. Where i could I hit 6500 RPMs in DS mode. Don't get me wrong: there is still some hesitation, but seemed better.

I really don't experoience this Flaring Issues. I watched my Tach closely and other than normal behavior of shifting into higher gears while accelerating, I didn't see or feel 200-500 RPM "flares".

It may be that following the advise from other members on different, but Tranny related sites when I first got the car in June - where they said To Hell with the deleicate Breakin driving, drive it hard. Even my dealer at that time told me to drive mostly in DS mode until she breaks in some more.

That's the best I can offer on the Reflash. I am certainly more pleased than the other day. But it's not Utopia - afterall this is a common complaint of 7 speed auto trannys... check other forums: Ford & Lincoln for one, don'y know about Lexus, etc.... Many other carmakers use 6 speed Auto Trannys, that one extra gear does affect the behavior.

I will say another thing as an overall observation of the 2010 G37X compared to the 07 G35X I had, I'd say I'm getting about 10-15% better MPGs in similar driving modes. This 100 miles with a computer reset - driving a little more aggressive than normal -22.9 MPGs on winter gas.

 

Almatti: Damn man thanx alot,, Yea the gear hunting is rediculous, Especial when I'm doing 35MPH and it's in 5th FN gear..( Check with manual mode) DS Can't even use it car drives exactly the same as drive, NO downshifts when slowing and doesnt hold gears longer, Drive the same .. I have tried putting it in DS mode and drive it like I stole it but still drives the same.. BTW I'm just outside of Boston so I know the crap weather you are having.

 

Yup, I'm disappointed in the DS mode after the reflash, it drives just like D mode, hardly any difference. It tries to get to 7th gear asap just like D, and engine braking when breaking hard is reduced. DS mode did not require any changes it was fine.

D mode is definiately smoother, especially when coasting to a red light. I used to have flares after a warm engine start, now that's completely gone.

Throttle sensitivity has been reduced. It takes more throttle input to drive aggressively now. I still haven't made up my mind about input lag, it seems about the same.

 

now i'm undecided again. FML

 

sniper27: Isn't America a great place. we get to make Executive decisions about so many things!! Lunch choices, what type of clothes to buy, what kind of cars to buy, and now what kind of Menu of Automated Digital enhancements we can make to our cars.... Man, in the "old days" all you could do was adjust the Timing on the Ignition, change some spark Plugs & Ignition wires, exhaust systems & manifolds [not that I ever did it], to enhance the performance of your car. Now we decide from a "menu" of Electronic Control Modules software programs to change the way the car performs.

I am sorry for the number of posts on this thread, but if you read my posts, this freakin' 7 speed Auto Tranny ruined the car's sportiness and driveability > compared to my 07 G35X anyway. I am hoping that through the course of ownership, I will achieve total satisfaction with the perfect blend of performance, MPG, throttle response.... Thank God there's no ECM for the suspension and steering.

IMHO, if you are happy with your car's behavior - let this ride out some more before you proceed; don't be anxious about it. It will drive you Nuts; I found that to be for me.... The TSB's not going anywhere and there will be more I presume. Just be sure that your dealer tells you Specifically that they are going to Apply This!! On my 07, my dealer (not my regular Service Advisor that day), decided on their own to apply a Reflash that affected the terrific throttle response in that car (some folks didn't like it - too sensitive, I loved it). I was livid when I picked up the car - I was reading this Forum about the results. I did not want it. Anyway, long story, but excellent Dealer - ordered a new ECM that had not been reflashed with the new software at that time, installed it, under warranty - no charge. Still wasn't exactly the same but it was closer to the original.
