Curious, have you had the update applied? You may have mentioned this in a prior thread, sorry.

I had mine done a year ago or more and it really helped. It's still a little goofy sometimes but not as bad as you make yours out to be.

Have you had anyone else drive your car, to get their opinion?

 

My friend is going to take it for a spin this weekend. My other friend could feel it riding in the passenger seat. He is like, why does your transmission transmit so much without really doing anything you want it to do? Im like, your telling me.

Last time it was in they said it was up to date. So maybe a new one is in? Idk.

 

Im wondering if you actually have a BAD transmission.

Doesnt seem like there are too many that have gone wrong (even though a thread on this forum says otherwise) there is always the chance of something physically wrong with it.

Mine frustrates me, but unless I have a whole lot more patience than you do (HINT: almost impossible for me to have more patience than anyone else on this planet!), yours is an exception and not the rule.

Just drove mine today to work and did a little granny type driving and a little "kick it in the pants" driving and the car responded fairly well. Does it downshift as fast as I would like when in D? No. In DS? A little better. Paddles? As instant a shift as Ive ever had on a torque-converter-based automatic.

 

My 2011 7AT blew up at 22k miles the replacement shifts the same as the old one but now had a harsh shift into first when cold. Other than that I can live with the strange searching behaviour. I use sport mode a lot and it seems to shift better in DS to me.

 

Had it done today finally. I think there is definitely an improvement. I had a Q50 for a lonaner, and got to essentially take it on an extensive test drive. The Q50 definitely shifted better. I think it was still a little better than my G37 after the reflash.

(Aside: Definitely can't see me getting a Q50. Will have to see if the new S's steering is better. It was pretty bad. Felt like driving a Camry. It was a non-nav, so I am not sure how downgraded the infotainment was, but I was not all that impressed with it. The apps were kind of lame. I set the drive mode in sport and left it there. It 100% absolutely is less dynamic than a G37S, even though it costs a lot more. Seats were nice, I guess, and the trim was nice. The trunk looked like it was a touch smaller somehow. Hated the raised cowl line (man, I miss the old Japanese low cowl cars).


Edit: One more thing. This may be my imagination, but they did an ECU update, too. I think the automatic AC works better now. I had noticed that you could leave the climate control on 72 and not freeze in the Q50. After my service I actually got warm with it on 76. (For the record, I am cold blooded. If I could stay married, I would set the thermostat at the house on 68. I used to just turn it all the way to the bottom when I lived in a small apartment when I was single, lol. In our Acura I set the climate control at about 70 most of the time.)

 

After getting the updates, I haven't had any of the original major problems.

I believe our 7AT's ECU adjusts the transmission to our driving style as it learns from it, do they not? I've noticed that after switching consistently between slow and faster driving styles, it seems to get indecisive. Now I believe disconnecting our battery resets the ECU. I recently had done this while a friend did some work on it, and afterwards I was shocked, but i swear that the transmission felt smooth and alive again. But I can already say that it's slowly returning to it's indecisiveness.

I'll have to try it a couple more times to know if it does the trick for sure. If so, It's kind of annoying that those of us who don't have a consistent driving style would have to constantly be resetting our ECU's to get what we want. I'd also be interested to know if getting a tune overrides our 7AT's feature to adapt the transmission to us or not.

That's like mine. I installed the paddles and like having them there. I can't always trust the tranny to be in the right gear all the time, but I know I can pull that right paddle anytime and be where I want to be. Most of the time I don't have to downshift, the car does fine on it's own.

 

Should I have the 7 speed transmission update on my 2011 sedan, even though I don't have a problem with the transmission? My warranty will be up in November. Will I be missing something?

 

I unplugged the battery and just left it for about 12 hours. Car felt better, but i can just envision it coming back. It still flaires and kinda doesn't shift smooth so who knows. Im going to talk to the dealer this week and see if there is anything they can do. I am just so fed up with this car and trying to make it livable.

 

Waiting for the ECU to reset.

 

If you use this gas pedal / timing method to reset the ECU, be sure to use a stopwatch or have someone else count seconds for you, as timing is a MUST for this to work. I've tried it thinking I can count out the seconds in my head, but it doesn't work. If you time it right, it does work.

 

I had it done. I think it is worth it. I actually leave the car in drive now instead of driving everywhere in drive sport. It may have already been done...I have heard some dealers do it as a matter of course.

Unless you put ungodly miles on your car, you should have more warranty left. Power train is 6 years.

 

I was told by my dealership this week that the rough down shifting issue was normal on the 2009 g37xs sport car, can some one confirm this comment??
tks

 

My G is at the dealer. Told them I didn't want it back until it is fixed.

 

the fist time my car goes into 5th is "slides in" after that its fine ? Reprogram?
