Oh well, it was too good to be true!
The flaring between the 3-4th gear change is back. Started doing it again on Saturday 18th. So the "fix" lasted just 3 days. Damnit!
I was able to get it on video this morrning and drove straight to the dealer and showed them. The foreman is going to drop past on his way to work tomorrow morning and we will take the car for a run when it has sat again overnight so he can experience it first hand.
So, back to the drawing board. Twice now they have done the PCM update and transmission relearning process. Batting 0-2. I think at this stage we can safely say that doing that again isnt going to solve the problem.
Will keep updating as we progress.
The dealer's foreman came past this morning. Firstly, I showed him the video I made yesterday and he said that was very clear. Went for a test run - and you guessed it, it didnt flare. Heres the videos. Make sure you go to full screen and turn volume up full.
But anyway, he was satisfied wth the video and asked me to send it to them. We chatted about the two previous software updates and i mnetioned that this latest one seems much better, and I also commented that there seemed to be little point doing the same thing again and expecting different results. He agreed.
He will report back, and Mazda will decide what is to be done, but he thinks that the module that controls the transmission will need to be replaced.

The car went back to the dealer yesterday for more tests on the transmission. I had also sent them a couple more videos of the issue happening.
More data downloads, data sent to Mazda HQ in Aus for analysis, then they did more tests. Picked the car up yesterday afternoon and the service advisor said they were waiting to hear back from Mazda Aus on what would be the next step. He said that this is NOT the same issue as other people had experienced a year or more ago with auto transmissions not engaging as has been discussed elsewhere on this forum. Lucky me - It is something theyve not seen before.
Anyway, at lunchtime today I got a call from the dealer - Mazda is going to replace the transmission. Its been ordered and will take a full day to do the change. Not sure when it will happen, they will contact me to book it in once the new one arrives.
Will update after new trans is in and been running for a week or two.

Also, every Jeep dealer in my area in LA had "never heard of N23 problems before", yet there were 100+ page threads on multiple forums about it...don't give that damn dealer AN INCH! (or is it a centimeter over there?)
Anyway, im not expecting any drama, Mazda has already approved the replacement transmission, and its been ordered by the dealer.
I can only conclude that the data downloaded by the dealer, plus the videos i took and sent to them, and the work done by the dealer to (unsuccessfully) try to rectify it with software changes, convinced them that there is a hardware problem that warrants a replacement.
The local dealer has been good, Mazda took 1 day after the most recent tests to approve. So I am very pleased with their support. Really couldnt ask for much more.
Note: There are no other reports anywhere that Ive been able to find, on this forum or elsewhere, wth symptoms even close to what my car has shown. The dealer was upfront and talked about the transmission issues (same as others have reported on this forum), but as I said, the slippling/flare between just one gear change when cold hasnt been reported elsewhere that ive been able to find.
So its not at all relevant to compare this situation to the Jeep debacle.
I imagine that Mazda will be sending my transmission back to Japan to be dissected to find and address the root cause.
I had the exact same flaring issue that you have with my 2016 Mazda3. I brought it to a couple dealers. The one dealer I brought it to couldn't capture the data when it would happen so they couldn't do anything about it even though I had videos of it doing it. Called Mazda corporate and didn't hear back from them. Ended up trading the car in. Of course Mazda finally called back after I traded it in. I just recently got another 2016 Mazda3 hoping the transmission issue from my previous Mazda3 was just a fluke. As soon as I pulled off the dealer lot and it was about to shift into 4th, it flared, but it hasn't happened again since.Note: There are no other reports anywhere that Ive been able to find, on this forum or elsewhere, wth symptoms even close to what my car has shown.

This should be the final update on this issue.
Dropped car to the dealer on Wednesday morning for the new transmission to be put in. Took them all day and a bit of Thursday morning to do the change.
When I picked it up I then went for a good drive across town in the freeway to a mates place, did some driving around the suburbs over there, and then back home, did 140kms in total, 2 hours driving. Since then I have done some more local short trips as well.
So its only been 2 full days with the new one, but ......
The new transmission has performed flawlessly. So much so that it has confirmed my view that the original one was never quite right - this one, I feel, seems noticeably smoother and crisper changing whether cold or hot.
I had to reset the iStop system because it had deactivated due to the battery being disconnected, I called the dealer to tell them and they said they would do it for me, but I googled and found the procedure online and did it myself. Working fine now too.
I checked but they said there was no running in required, just drive it like normal. So thats what I am doing.
So I think I can draw a line under the issue and tick it off as "resolved", and I would like to say thanks to Mazda Australia for their good customer support, and to my local dealer Oldmac Mazda for taking care of the work, and keeping me informed along the way.
By the way, i did recently find one other report from a CX5 driver of the same issue, including a video that showed the same symptoms as mine. His auto was replaced as well under warranty and the problem was solved. Similar build date to my car.
