Oddly enough, sounds like the fluid is incorrect. Even on a hot day it shouldn't do any of that. However, it can do a bit of a jump if you are slowly cruising in high gear and then press hard on accelerator, it can rev up enough to punch into gear. But if you are getting a whine sound into second that sounds like the fluid is massively burnt and causing a blockage into the tq converter which is starving for fluid which would cause your issues especially at temps. This typically is something caused by abuse of the fluid in general, but with only 8k I would lean towards a manufacturing defect. But Get it into the dealer and diagnosed/repaired right away because the longer you let it go the more they will point towards you abusing it. The first treatment will likely be changing out the fluid.
I had the same thought. Incorrect or contaminated fluid. Check the fluid level (procedure should be in the manual, if you're unfamiliar with it) and wipe the dipstick on a white cloth. At 8k, the fluid should look fresh, if it's brown or has a burnt smell, there's definitely something wrong there.

There's always a chance of an isolated manufacturing defect in the transmission itself, and perhaps there are excessive metal shavings wreaking havoc in there. That's something your dealer would have to diagnose.

Good luck, and keep us posted. I'm not far behind you mileage-wise!

Hey man, were you ever able to figure out what was the issue with your transmission? I think I might be experiencing a similar thing, not as bad as you but I feel like the shifting should be a lot smoother than what it is now. My car only has 2000 miles and I haven't really thought about it much but after taking my wife brand new 2023 CX5 for a drive that thing has buttery smooth shifting compare to my 2022 Mazda 3.

Not yet but I am planning on looking at the AT dipstick out of curiosity. The car still drives about the same – sometimes fine, but often very annoying. Have driven a couple other cars (high-mileage 2015 4Runner and low-mileage Volvo XC60) and both have extremely smooth transmissions that are willing to gently downshift for acceleration ... but the Mazda is a different story. Will let you know if I find anything.

There was a great thread the other day about resetting the Skyactiv learning system for "factory fresh" behavior on your AT. That's another option I'm mulling.

Have you tried to zero-base it, then start driving it as you wish to, and let it re-learn that?

Yeah, I did that last week already but not much changed, car still drives/shifts the same. This is extremely frustrating because even if I was to go to the dealership the "issue" isn't really easily reproducible and even if it was it's not that serious and I'm sure Mazda will just say "it's normal"

@BenDoyle I am having exactly the same issue and I absolutely regret buying that car. I am absolutely pissed off every time I drive it. :(

  • It sometimes jerks and jumps after shifting to second or third. Like if a person can't drive a manual in driving school and it jerks on first gear.
  • Almost all the time it "stops accelerating" and jerks a bit when shifting up.
  • When it shifts to 5th gear, a clunk/thud is felt from the engine. Like if you dump a clutch in a manual too fast and the engine moves in the mounts.
  • When you accelerate to 80 kmh, let off gas and the car starts to down shift to 4-5-6, it like "flares" or moves the car forward, like if you pressed accelerator a bit.
  • Dowshift jerking also, but that's normal for TC transmissions I think.

First visit to a dealer - Yeah we feel it, let's reflash the transmission and run adaptations and see if it's any better. No change.
Second visit to a dealer - Accepting technician nods to everything I say and show to him. Week no change. Then after some urgency, they ran all the checks, scanned for codes and told me that the car doesn't show any signs of bad transmission and that the warranty technician didn't feel anything wrong.

"The symptoms you complained about in order sheet XXXXX / non-standard behavior of the automatic transmission were properly verified by the service background, both by test driving, checking stored error messages and other initialization steps of automatic transmission parameterization. Since the aforementioned interventions did not result in the claimed defect, there are no error messages stored in the event memory in the automatic transmission sector, the claim was evaluated as unjustified."

When I drove the technician after a heated discussion in there, when it jerks, he smiles and tells me that he doesn't feel anything and that everything is normal. :)))

I think they know pretty well that the transmission is shit, but its a engine/transmission/software combo I think.

No other car I ever drove did any jerking and it shifted smoothly. Old mercs, 2003 passat tiptronic, BMW F01 transmissions, DSG passat, DSG arteon, new mercedes V, new Supra - ALL of the cars shift smoothly.

Sorry to hear that others are having little success in diagnosing these poor shift behaviors. I like my dealer, but I doubt they would be any better. Unfortunate to think that the transmission is slowly destroying itself, but not fast enough to do so under warranty!

If any Mazda Skyactiv 6AT owners want to chime in, please do so. The more information we have, the better. This weekend hopefully I will remember to look at my AT dipstick.

@BenDoyle , take extra care to NOT get any dirt in the ATF dipstick hole. If it were my car, I'd first remove airbox to clean IT, and to allow good visual- and cleaning access to the ledge where the dipstick is... YMMV, but just 'sayin.

Sometimes it's "stack-up of build- tolerances" that conspires to make the car not perform smoothly. For me, that'd be unacceptable, and despite $$ loss I'd sell and move-on...

Keep in mind Mazda FZ fluid discolors quickly and smells bad/slightly burned when brand new due to the specific friction additive package it comes with. If the fluid looks odd it may just be normal and not indicative of a problem.

Based on some Google Fu.. early transmission failure was common in the second Gen 3s.. especially the 2010 models. Current models are said to be better but will sometimes start having symptoms of failing around the end of the warranty period.

Getting a 3rd party opinion may be worth your time and some minor expense.

Thanks all. To provide another short update:

My Japan-built 2022 is now at about 16,500 moderately hard miles. Whenever I drive other automatic cars, I'm still amazed at their smoothness. My 6AT is much the same as before. The following symptoms may sound familiar:

-Most of the time when cruising (30-50mph), it utterly refuses to downshift, unless you mash the throttle (dangerous and annoying). It likes to sit in 6th and flutter the torque converter instead; this means there is usually zero throttle response unless you force a kickdown. If you DO mash the throttle and let off too quickly, it gets confused and produces a wicked shift flare. Downshifts are sometimes imperceptible under light load, but moderate/heavy load makes them excessively harsh.

-Poor software tuning means that, if you put your foot down while it's starting to upshift, it won't stop -- it will just carry on upshifting, leaving you in the lurch unless you floor it.

-It's often very slow to engage when going from R-D at a dead stop. I've noticed that it most commonly gives me the "whiplash" effect when cold. On occasion, you'll go from R-D, hit the gas, and nothing will happen. The car will get very close to stalling out. Then there's another second or two with no throttle response, before the car slams into first and takes off (again dangerously) like a stabbed rat.

-Has a hard time taking off from stoplights in any kind of hurry. There will be a shudder and a brief pause before it gets up and goes. The torque converter often slips far too much from a dead stop, which makes it feel like a bad CVT. It will feel held back and then it will start to pick up speed after a few seconds. With this car, there's a constant feeling of 'catching up' with itself -- it's held back initially, but then it surges forward unprompted. A very hard car to drive in a smooth / linear fashion.

Some days, the transmission is pretty good. Other days, it sucks. It's not bad enough for me to surrender the $150 diagnostic fee at the dealer (because they'll tell me it's normal), but it can always get worse. With any luck it will grenade under warranty.

I continuously encourage other 6AT drivers to chime in with their own thoughts, opinions, and driving sensations.

Thanks to all for lots of great info and suggestions!

Another interesting point -- I've noticed that adding a second passenger to the car makes it feel much smoother.

Debating whether the AT software reset is a good next step.

The car has been nerfed for cruising and higher mpg goals.

They aren't targeting enthusiastic drivers any longer.

I remember hearing that. Combined with the torsion beam at rear, it seems like Mazda should decide between comfort and sporting character.

I definitely think it is not normal. Someone was riding in my car the other day and remarked how smooth it was. It is definitely the smoothest driving car I've ever owned but I still prefer CVTs. Can you use the paddle shifters or put it in manual mode to see if it has problem changing gears when you tell it to? Maybe you can find a dealer that will go for a ride with you for free so you can get them to admit something is not right before they start diagnosing it.

Go to the dealer and tell them you are having a "delayed engagement". This is usually indicative of a pressure issue or a combination of solenoids not allowing the Low/Reverse Brake and the one way clutch to actually operate like it is supposed to. It could also be causing the slip felt on take off.
