I personally believe there is some kind of incentive for giving "good reviews", not sure what those are though, my opinion of course .

wlkeel

Perhaps because he was driving the snot out of it. As he said, "Sport+ and manual shifting are encouraged for the most engaging experience". Heck, mine is fantastic in this mode, no problems at all. However, the low speed hiccups manifest themselves in full auto mode, as described in the following:

2015 Acura TLX I-4 review notes | Autoweek

In my case, it occurs mostly in Sport mode, hardly ever in normal mode (I don't use econ mode). Right now it's more of an aggravation, but I still want the programming fixed since I prefer to drive in Sport.

Anyway, if he was driving aggressively and mostly in Sport+, he might not have noticed any significant problem. And who knows, he might be getting some kickbacks for writing a positive review.

Not everyone sees/feels it--I don't have issues, so undoubtedly that makes it harder to resolve. Have been in Sport since day 1.

This is 100% accurate. Plus - as has been mentioned not every car exhibits the same quirks. This is, in my very humble opinion - is mostly based upon long-term driving habits and why not many reviewers and regular schmoes have any issues with the DCT during a test drive.

I just did a new software update on my TLX 8 speed DCT today.
Version-DFA560
Part number 37805-RDF-A56 released on Wednesday.
So far so good, no lurching, immediate downshifts and better response from the paddle shifters. This latest version should be out in the U.S. as well. I also performed the idle learning procedure afterward. I hope this update will work for others too.
Good Luck!

Thanks for the info. Please keep us up to date on your experience. I hope this update finally resolves the DCT issues for those of us affected! Which dealer in Ontario performed your update? Do all of them know about this already?

I'm also wondering if outside temperature influences the manifestation of the DCT issue. For example, today was quite warm in Southern Ontario (>13 C at noon) and I didn't notice the weird lurching while coming to a stop. On any other day these past 2 weeks where the mercury has hovered slightly above freezing, the lurching happens at least a few times during my commute.

Dutchy....Thanks for the update and as others stated, please keep us updated. I am hoping this will solve this DCT issue once and for all.

Dutchy

I did the update myself as I work at a Honda dealer. Our programming tool got the file updates on Wednesday. It is the same tool for Honda/Acura so all dealers should have updated their ECM/PCM programmers this week. This time it feels more than just weather change. The paddle shifting responds instantly to up/down shifts too now, no lurching, etc. It is day 2 since my update and the DCT is behaving nicely.

BellaTLX

I have ZERO issues. Sport mode all the time. Smooth as silk

Do you have anymore salt to rub in our wounds?

Honda released new HDS PC/MVCI software version 3.016.018 today. It contains program part number 37805-RDF-A56 (program ID DFA560), as Dutchy mentioned above. Hopefully the TSB will be issued soon with full details.

wlkeel

Thanks Dutchy and EE4 - sounds like good news!

Nomad346

Okay thanks for the info. I will e-mail my dealer this week and see what they have to say. The two issues bothering me is the lunging while stopping (mainly in Sport mode), and the rather jerky shift between 2-3, 3-4, again in Sport, while moving at low speeds.

I hope the problems are banished for good and all of us owners can finally have some peace of mind with the car!

TSB 15-021 - Transmission Slips or Shifts Hard When Cold was released today. Per the TSB, the program part number is 37805-RDF-A560 (program ID is A560).

See the 2015 Acura TLX TSB thread for details.

SYMPTOM

The 8-speed dual-clutch transmission (DCT) slips or shifts hard when cold, usually on 1st to 2nd up shifts. The client may also report about feeling bumped or jerked once the vehicle has come to a stop. After the transmission warms up, it shifts normally.

We have a winner!

I may take mine in for the first oil change a little early to get this one done! Plus the nav update and the cross traffic TSB. I suspect they'll have my car for a day or two at this rate.

wlkeel

Not sure it's a winner for some of us. First of all, many of us notice it when cold, but also to a lesser extent when warmed up (TSB says "After the transmission warms up it shifts normally"). Secondly, the applicable VIN numbers are FA000001-FA011573. Mine is FA014597 which is outside the range. By the way, my build date was around 2/2/15.

Oh well, I had a day or so of high expectations - guess I'll just go back to wishing.

My dealer is having a welcoming get-together later this month to meet the service personnel and get questions answered one on one. I'll check with them then. Luckily, mine isn't so horrible that I have to have something done immediately.

wlkeel

Nomad346, in looking at past posts I notice that your build date is also Feb2015 (same as mine), so you may be in the same boat re VIN numbers.

Please keep us informed after you correspond with your dealer.

Thanks

CheeseyPoofs McNut

Mine is FA002873 - so I'm in the range. And - that pretty much describes the behaviour of my car - it's shifts hard from 1 to 2 when cold (regardless of the outside temp) and I've had the "lunge" happen twice. So I'm going to be taking mine in to have it done.

I wonder what the "clutch break in procedure is?

wlkeel

Glad you're one of the winners, Cheesey.

Actually, the TSB may show some progress - they're starting to show some formal recognition that there may be some reprogramming required as real world data show up. Hope so.

Nomad346

The TSB doesn't include Canadian VINs which number FA80XXXX so I don't know if the dealer will apply it. But I am hopeful since Dutchy, another fellow Canadian TLX owner, said Ontario Acura dealers got it already.

I plan to take my vehicle in on Friday and will let you know how it went

Dutchy

Well I did the software update already so tomorrow I'll do the clutch break -in procedure.

Tjb117

Well, I went from really excited to really disappointed pretty quickly when I realized my VIN was just outside the range in the TSB.

So am I pretty much out of luck then?

As aggravating as the jerkiness and everything has been, I've been holding out hope that soon enough the "fix" would be available and all would be good.

So, it's a bit of a letdown when this "fix" is finally available, but not for me

nebula

So when it says it fixes hard shifts when cold can we assume this means or includes the clunk that myself and others are experiencing going from reverse to drive?

TSXtravis

Do you know if this is the same as the update that the Acura tech line suggested about a month ago? Or is it a new one? Or the same update, just released as a TSB now. I see on the TSB it says "Database update 17-Mar-2015 or later"

a77

Dutchy, do you know affected Canadian VINs? Thanks.

Dutchy

No sir, I haven't seen a Canadian bulletin yet. Mine VIN is very early something like car number 360.

Dutchy

This update was just released last Wednesday.

Nomad346

Will dealers perform the update without an applicable Canadian TSB? My number is 1800.

NRS78

I was all excited when I saw this TSB released, and e-mailed my service manager to get it updated on my car. He just e-mailed me back and said that the TSB is really just the official release of the 2-2-15 update (2nd software update) that some of us have received through Acura TechLine. I can tell you that it DOES NOT fix the hard clunk from R to D, I still experience that. It also does not completely resolve the shifting when cold. It is better but not a complete fix. Since the update, I have not experienced the hard shift into first as I come to a stop, but I know others still do, who have this update.

EE4Life

Thanks for the info from your dealer.

The TSB has two parts...update the PCM A/T software and do the clutch break-in procedure twice.

We would need confirmation that dealers did both parts of the TSB with the pre-release software, instead of just updating the software. That could make a difference.

NRS78

Well I know my dealer did the clutch break-in after they performed the software update in February. I spoke directly with the technician who performed the update after he completed it. He even had to wait a bit in between the first and second break-in because the ATF went above recommended temp, so he had to let it cool down.

nebula

I thought Dutchy said this did help his car resolve the R to D clunk, I could be wrong though. I would like to know if Dutchy can confirm or not. I also noticed sometimes I see a DF infront of ID # and sometimes I don't. Does those letters make a difference. It doesn't make sense if the update helped Dutchy's car and not others.

weather

NRS78...Are you sure you got the same software update? Why did some just state that this software update just got released less than 2 weeks ago, yet yours was done in February? Any chance that this software update is not what you got done?

Darn it Acura....why is there so much confusion. One and correct software update....get it straight.

NRS78

I specifically asked my service manager that question: is this TSB the 3rd software update? His reply was that his technician talked to his contact at techline this morning and "the TSB is the official release of the 2nd update. There is no 3rd update at this time." I received the 2nd update back in February, when Acura was testing it. The technician at my dealership is part of the super tech group, and received it through his contacts at Acura Techline. Is it possible the release a couple of weeks ago was for Canada? It seems like those updates are coming out later than for us in the US.

I don't know. I'm just going on what I have been told by my service manager. It is frustrating.

weather

I appreciate your answer...and I can feel your frustration as with most other members having issues with their Trannies.

Our little 5-speed 2.0L ILX is behaving flawlessly and exhibiting more power than what the ratings would suggest. I am not regretting holding off getting the TLX seeing all these non resolved issues. I know IT WILL be fixed but I am shocked its taking this long.

colohusker

Actually I don't think that's true. I looked at my old paper work and the early February update was dfa550 (not dfa560) and the it was 37805-rdf-a55 not (a56). So I think this one is new.

Excited to here about this though. Hopefully it will help as I continue with the same issues. Just looked at my vin and I'm 000353 (wow I was early on this train) so I qualify.

Once done I will provide updates. Thanks for this new info guys. Off to the shop!!!

TSXtravis

Thanks!

CheeseyPoofs McNut

Thanks for being an early adopter! I'm sitting at 40% oil life so will likely wait for reports on how effective the TSB is before pushing the issue with my service guys. That said - the hard 1 to 2 shift in the mornings is getting on my nerves more because I think about it now! I'll be happy if we can smooth that out.

Regarding the R to D clunk that others have issue with - I pause for a second in N then shift into D and it never clunks into gear anymore. A workaround I can live with.

Buzz1317

I had my vehicle in the shop on 4/13-4/16 and was told by the service manager that they might try doing the breaking twice. He said there were no TSB's on the vehicle and that the update mentioned above was done to my vehicle back in March. When done it worked great but has progressively gotten choppy again. That is what it was in for!
I also spoke to the Acura Client Relations Rep on the 15th and he was a bit arrogant and said that nothing could be done to my car. At the dealership they talked with the Tech line twice on the 15th or so they said.
How do they communicate? My vehicle is one of the ones on the VIN list as well??
I have a message in to try and get it done again... Man!

nebula

I have to try that trick and see how it works, still I hope the TSB resolves this issue as it is unacceptable.
