I believe that I heard that somewhere as well. I love the idea of great gas mileage (my daily commute is about 100 miles). Just hope that they can get the programming right to reduce the delay in downshifts, especially when needing to accelerate for merging/passing. The DCT might be the ticket.

I totally agree about the delay in downshifts. I sold my 05 TL 6SPM for this 9SP Zf tranny in the SH-AWD Tech. I love the AWD but I just don't understand why the Acura engineers allowed this transmission to go to production. It just doesn't make sense. My car is in for service today getting the B16 service done (11k miles) and they are also applying TSB 15-34. I received a 16 MDX and the shifting is a lot better and more responsive. Why can't they get the timing right for the much lighter TLX? So aggravating.

Calls to Acura Client Relations have not worked. If you would like to be heard, simply sign the document. If you would like me to reword any of it, let me know. Maybe this will be a good way to see how many individuals actually want an improved transmission.

Just one of a few ideas I have... Thanks for your time! I will be posting this on a few threads, Moderators, so I hope you don't mind.
I signed.

I signed as well. I also posted messages on twitter to @Honda and @Acura. I would encourage all to post on facebook (I don't do facebook), twitter, etc.

Just a random thought as I sit hear and read through these posts - i wonder if any of the 2016's exhibit the transmission behavior. I'm sure Honda/Acura is working their tail off to fix the issue since this transmission is in the TLX, Pilot and MDX. Time will tell.

It is somewhat annoying that this TSB does not apply to earlier 9ATs as well. Some have speculated that this is due to an actual hardware change in the 9AT during the spring of 2015.

Son of a bitch. My VIN is before the range but does all of those things. So annoyed with Acura. They ought to volunteer to replace these things because if they don't, my next car WILL NOT be an Acura and maybe not the one after that, either...

So my car threw Transmission problem while i was driving in traffic. Then another warning popped up showing BLIS not working. I pulled over after a few kms when I could do so safely. Stopped the car, waited for a minute or two and then restarted, the warning is not there anymore but that was worrisome.

Have booked an appointment for inspection tomorrow, lets see

Its a 2015 V6 SHAWD Elite which I bought CPO in end of July this year.

Your problem is not related to this thread (9 speed). Yours is a 6 speed transmission. BLIS is the blind spot information system also.. so not transmission issue here.

HOWEVER, what exactly was your 6 speed tranny issue? Were you having like.. judders?

You did the right thing -- let them tell you what's wrong. There are too many cases on here of everything blinking all kinds of things and everybody seems to have some different solution as to how it was fixed. Often, the errors being displayed don't explicitly state what's wrong. Hopefully the dealership can get an error code.

Assuming he has a TLX, there is no 6-speed transmission in the TLX. All V6 TLX-es are 9-speed transmissions. The 4-cylinder TLX engine is mated to an 8-speed transmission.

I agree with datadr below. This sounds like a lazy, disconnected dealer.

Its a 2015 V6 SHAWD Elite which I bought CPO in end of July this year.
So when i went to the service center they first told me they might charge $137 for inspection if I am not covered (this is the lamest thing I have ever heard) and then made me sign a document which stated the same(luckily in the end no charges were applied). I am still in the factory 4 year warranty and have bought 7 year CPO warranty.

The mechanic who looked into my car was really good. He checked the messages in acuralink but didn't find any active errors. So he started checking for software updates and found that there was a big software update for VSA/TSC (Big as it took him almost an hour to update, he kept coming to me to show the status of download ). After that he took a test drive where he discovered that I had some jerky shifts in lower gears(I didnt complain as I thought this is how its supposed to be after reading the transmission woes on this and other forums :|). So he did an idle reset(some elaborate process where the engine should be warmed at 90 deg and at some rpm etc etc). He said the car will learn my driving for next couple of days.

And boy what a world of difference it has done to the car, the low end jerks are almost gone, the car doesn't bog down on sudden acceleration as it did before and overall the transmission shifts are barely noticeable. The car has become lively compared to how dull it was before and is very enjoyable to drive now.

I would definitely recommend getting the idle reset done if you haven't already.

This guy was old school mech and really thorough in his job, I am going to ask for him going forward and report every small issue to see what he does to fix it

Thanks, I think the VSA old software patch could have been the reason, he did say that these patches make big difference sometimes.

Yes mine is 9 speed

LOL I do have an MDX with 6 speed so rest assured I wont get mixed up on that

And yes I knew BLIS has no connection with transmission but that also gave me some relief that these warnings are not the cause but an effect of some other problem.

If this is the DCT on the '18 Accord 2.0, this is good news. I'm on the Drive Accord forum, owners love it.

the jerks are back and facing a new problem now, after making a turn and sometimes after overtaking as well, the car bogs down as if the engine was shutoff or something and just wont accelerate, takes a good 5-10 seconds before it regains and starts responding.

Check your VIN. You might be eligible for a replacement.

When they do the Idle re-learn procedure the transmission shifts much better. Then the transmission proceeds to 'learn' your driving habits and after about 500 miles it is a mess again. You can take it back and have them do the re-learn again... every 500 miles. Maybe they will get tired of you and replace your transmission. But if your VIN is not in the range on the TSB then they won't do much for you. I wish they could disable the learning mode. That seems to be what makes the transmission a mess.
