2019 trans shifts fine...

This here makes sense. ^^

A lot of trucks that got TSB's at the dealership didn't get a sticker. Mine didn't & it wouldn't make sense to put a TSB sticker on a brand new truck

 

Thanks, I got them from a local 4x4 shop here in town. Rock sliders with removable steps.

 

This is just how OEMs operate speaking as a former dealership tech to a few different OEMs. I also think you have a fundamental misunderstanding of what a recall is for... a recall is a safety issue. These reflash issues affect a small proportion of owners that sounds larger than it is because an "enthusiast" forum like this is more likely to bring out the issues. A reflash in most of these cases is a QoL improvement and 95% of owners won't realize there's an issue. Like most software development, if a reflash fixes a potential issue, there's no reason not to roll it up into the next major release which, in this case, is the next model year.

All vehicles will have lingering issues that 2% of owners notice and other issues that sound like prior problems that are just deviations from the norm. This is literally the definition of an echo chamber and TW is so far from the truth about these trucks it isn't even funny.

 

I’m the op and dont have an issue. My Taco shifts smooth as buttermilk? So what is it exactly I should be fixing?

 

All steps are removable if you use them as sliders

 

Lol, that’s definitely the harder way to do it though. I’d rather use a socket wrench...

 

Didn’t say you should be fixing anything... recent posts suggest some of the 2019 owners are experiencing the same transmission issues as the 2016-2018 owners. Your 1st post asked a question, I’m just trying to help fill in some of the answer. My truck shifts fine as well... no problems noted except an occasional unwanted downshift here and there, yet my late 2018 doesn’t have the TSB as indicated by the ECU code. Not all transmissions exhibit the harsh issues complained about on TW, nor has anyone been able to verify the new models have the TSB as standard... it’s all speculation at this point.

 

Ok... thanks for offering more insight and speculation, still looking for collaborative evidence (aka factual based document stating the aforementioned TSB has been applied to the 2019’s).

 

You'll never find it because it doesn't exist. There is literally zero reason for an OEM to release a vehicle with the same potential problems as prior model year vehicles and if you can't see that then there's nothing I nor anyone else can do to convince you otherwise. Again, these are viewed as QoL improvements because they only affect a small subset of users. If nobody posted the TSBs or complaned about the issues, 99% of owners wouldn't realize they had the issue.

 

You started the post with “OP, ...” I took your post as suggesting that I should bring my truck back to the dealer to be checked. That’s why I asked what exactly it is I should be checking since there is no issue. I now see you were posting in general and not me specifically.

I will say that I did bring my truck by the dealer the day before yesterday to have the trans fluid checked after seeing that thread. They couldn’t do it at the time but they did tell me that they had had a few low fluid issues with the prior years models, but none at all on the ‘19’s.

 

I have zero problems with my 2018.

 

Then help, me understand why the 2016 model year exhibited this issue, TSB issued and no change for 2017 (repeat issue in 2017) and no change for 2018 (repeat issue again for 2018)... and now, they incorporated into 2019? Slow learners at Toyota I quess?

 

I think it would be obvious that it's because the OEM doesn't realize these small issues right away. This only confirms my point that it only affects a small subset of owners because clearly enough weren't complaining that any action was warranted.

No vehicle will be perfect to everyone and no OEM will fix every issue. If this is what you're expecting you'll only be disappointed.

If you're wondering about drivetrain issues persisting, there's several dozen scenarios that play out to the same set of symptoms. What you perceive as the same issue can have about 50 different causes and just because a few people still have the same problem doesn't mean the TSB didn't solve the issue for the majority.

 

Thanks @velogeek for posting some sanity in an insane world (a world I just can't quit for better or worse). The way I understand it, ECU programming is just that, a program, well firmware would like be the more accurate term. It will have bugs that affect some and not others, requiring updates/patches. It appears that Toyota releases a patch about once a year, that will address a number of issues. What makes things confusing is that once the patch is ready for release, it still takes a number of months to publish the various TSBs that address each fix that the patch was developed for. For instance the last patch fixed three primary issues (3 separate TSBs all having the same reflash) and also further refined the shifting. I imagine having to make sure the patches are still compliant with CAFE regs slows down and cripples the update process significantly also.

I have heard of other vehicle manufacturers doing the same thing. So basically the new normal for vehicles is the new normal for any electronic item, expect to update the software/firmware repeatedly until you get a build version you can live with or they stop putting out updates.

 

@Tacoma3rdGen why is my post quoted in this thread? Nothing I was referring to in my post was related to '18s and up since they use a different ECU code. I'm not sure if what you're saying is that when a TSB comes out it is NOT applied to newly produced vehicles as the standard ECU version at that point?

 

I have an 18 and have had all TSB done in regards to drivability. Mine still shifts hard and erratic pretty much all the time. Always searching for gears. I think most are used to it or are used to Toyotas in general. This is my first toyo and second I have been in. Havent been in one since a 96 maybe. The auto just shifts funny AF.

 

its probably because its new and has not done much of any trans learning. once it has "learned" values it will likely start acting up. When i first got my truck (2016) it drove great for the first few months then went to crap. If you clear the learning with techstream it will be back to driving pretty good. My guess is after a few thousand miles you will be back here looking for the OVTune ;-)

 

People act like this isn't normal but this is what literally every vehicle does now. It's all about being in too high a gear all the time because it increases economy. The difference is that this transmission isn't tuned to soft shift (this is actually a good thing) and with only 6 speeds, it's a bigger jump between gears than something like the 10 speed Ford/Chevy or 8 speed Ram.

 

Velogeek........no truer words

 

19 2wd TRD sport DCSB with a bed cover, 91 mile drive doing 70, cruise on, flat ground with calm winds. Couple occasional overpasses in which it would downshift, clicking it over to S causes it to do that less often I noticed. Beyond that, as you can see, I can’t complain.

Had a bit of a rough up shift In the beginning I noticed when cold and took it to the dealer. I suspected low tranny fluid as I’ve had a vehicle behave like that once and that was the issue. Got the usual, “Uhh, it’s normal at the dealer. So I went to the parts department and bought a quart and latter added it the next day with it cold while doing the temp check mode thing with the shifter and the overflow bolt. It took almost 3/4 of that quart. Not a single harsh shift since, imagine that
