• Year: 2022
• 4WD or 2WD: 4WD
• Truck build date: 6/22
• Issues noted prior to flash/update (shift behavior, noises, etc) - if any
  Not really, engagement delay leaving from stop, but not easy to replicate and haven't tried much yet post update
• TCM version prior to update: 9BU3A
• Date of TCM update: 11/1/2022
• TCM version after update: 9BU8B
• Post update observations - anything "fixed"?: Inconclusive, nothing yet observed

 

Had my 2021 updated for the original shift shock tsb NOT yet for the pawl recalls.

• Year: 2021
• 4WD or 2WD: 4WD
• Truck build date: 3/21
• Issues noted prior to flash/update (shift behavior, noises, etc) - No real issues just wanted the latest flash at the time.
• TCM version prior to update: 9BT6A
• Date of TCM update: 3/22
• TCM version after update: 9BT6D
• Post update observations - anything "fixed"?: The shifting was smoother post flash and remains great today.

This was the tsb

 

Where did you get this from?

 

When I check the RO copy I have, it does not include the attached in "page of" count. Implies they provided the info because I asked. Because it is clearly a template, it may be something they all use but has to be asked for. I have seen version info added to RO lines also so it may not be required.

 

This works for Maineiac TCM info but not for mine and a few others I tried....

You can check to see if updates are available here: Nissan Publications

I suspect that recall updates may not appear here or possibly some delays before it shows as a general update. If I'm right, you can't just "ask" for the recall update to TCM without actually doing the recall. TSB's are apart from Recalls so to my logic this makes some sense.

Within each update download, there will be files to unpack. Thus far, I do not see where "changes" are documented. The purpose of the readme is likely for folder location after download/unpack.

A few posts, and my own experience, is that the time to reprogram varies. My dealer mentioned it has been slow to download lately... in a past life this would make sense - you download or check for one each time you do an update or if time has lapsed. Not checking only to find out later you assumed wrong is a good way to brick parts.

Where my Nissan techs at? Check my work! lol I have email if anyone has files. wink wink

Sharp eyes will notice the TSB search also, though I think subscription is required beyond summary. Most of us have little or no use for this subscription as there are other sources for TSB info.

Edit: I did not discover the page/site though I did stumble into it. Fairly certain its been shared in other threads, but seems relevant to add it here.

 

Forgive my ignorance, but do TCM updates override all prior updates? Like, is it all or nothing where you only need the most recent one? Or does each update affect something different, where you may need a combination?

 

I don't know if they bother doing checks like that

There are however iirc two diff flash methods. One for updates and one for bank modules

 

I know there is a prior TSB for a TCM update for "shift shock". If someone was experiencing shift shock and didn't get the update, but then got the update for the pawl recall, might it still be necessary to do the shift shock update?

 

Very unlikely

 

The "recall" TCM version 31039-9BU8B (4x4) now shows up as the available update in nissan-techinfo.com for the below numbers. Grains of salt, but may imply the TCM can be flashed to this version without recall labor op (think reflash, tcm module replacement etc).

9BU3A, 9BU2D, 9BU2E, 9BU8A

Because the file that is downloaded does not require a VIN, the further implication for us is that the files are the same and not generated on the fly. Does the "install" process check for an incremental update or just full send the downloaded file? I still do not have the data, but full send is my bet.

 

Quick question. I just picked up the 2023, when I go to www.nissan-techinfo.com and search the 2023, I don't see a service bulletin for reprogramming the TCM on the 2023. Although I have some shift shock around 1st and 2nd gear when accelerating, mainly when coming to a stop and I do not come to a complete stop. Since the recommendation for reprogramming the Gear Ratio DTCs Stored in the TCM does not come up for the 2023 the way it does for the 2022, does that mean it has been fixed between years?

Has anyone with a 2023 actively had it done a the dealer, or does it not need to be done?

 

The pawl recall update did not initially show in that portal even though it was available to dealers. Is it possible then there is an available update not yet visible to us? I suppose, but seems doubtful. Depending on the miles you have on it, the recommendation might be to drive more - could sort itself out.

All you really need for that site are the orig TCM#s. This IMO would be more accurate (within that site anyway). Plugging those in will show the vehicle and what if any the new TCM# would be.

That long winded response to say, I don't know. lol.

I just had my pawl fix completed. It took them about five hours to do it. For some reason my Accessorides remote start cable was unplugged afterwards so I had to reconnect that. They also didn't latch the hood the hood completely which I noticed when getting up to speed on the interstate.

 

Had my 2021 updated for the 2 different pawl recalls. they did both the pin and the software.

• Year: 2021
• 4WD or 2WD: 4WD
• Truck build date: 3/21
• Issues noted prior to flash/update (shift behavior, noises, etc) - No issues
• TCM version prior to update: 9BT6D
• Date of TCM update: 12/23/2022
• TCM version after update: 9BT8B
• Post update observations - anything "fixed"?: no change - was good before its still good

 

I had some TCM reprogramming done in the last three weeks. It helped the gear shock remarkably although there are still occasions where it happens inconsistently enough that I haven't discovered a causative event.

 

Just picked up my truck after the fix (pawl). Notice the truck is not jerking as it changes gears,it changes smooth from gear to gear but it feels like is less powerful, not sure though. It is smooth.

 

Based on below, this would be one item expected to be resolved in the TCM version issued for recall.

As a customer, if you dont ask for ver detail, it might still be in the tech notes for your RO. Better to ask.

TSBs are in several places via web, I see you already have at least one source 😉

 

What locations on web do you know about? For TSB'S Thank you

It was post #5 here and also given in the other thread where you acknowledged

 

I have had my 2022 3 months. Worst transmission I've ever had. Its clunky and indecisive. I drive stop and go for my commute, the constant up and down shifting is annoying. And will most likely break something

 

It gets even worse if you react to it or input without commitment. If on-off-on-off-on-off-on about all I can suggest is try to anticipate traffic and smooth out throttle inputs. This is likely more noticeable if aggressive.

None of the clunk thump thud buyers have had any volume of failures.

Also, without more detail (version tracking vs behavior/issue) this might be the wrong thread for general complaints or diag

 

As of today, not seeing any newer versions available for Gen2.5 or Gen3 4x4 (didn't check others).
