Finally a fix from Toyota for Stumble condition (TSB 0062-18)

Nope

 

Could someone provide in layman’s terms (I’m partially mechanicaly savvy) what the driver should feel in regards to the issues addressed in the section? My build date on the taco is 8/18 so I’m not sure if the ECU was updated on the build or not, and was awaiting the first scheduled service to ask them to check. I do notice some things with the shifting but I’m not sure if that relates to this or me just not being used to how the truck drives. Thanks

 

@inksin some of us don’t have 700.00.... lol I wish I did cause toyota service sucks they charged me for 2 quarts of oil over 5 quart limit they said the taco took 7 quarts, which is bs it only takes 6.2 quarts and they should’ve only charged me for 1.2 quarts not 2

 

If they can detect that you've altered the ECU, then yes you are on your own. Also, it's worth noting that OVTune has a pretty sharp disclaimer as well: "None of our products can be used at any time on any emissions control vehicle that is used for anything other than off-road performance. ALL Ecu tunes, Calibrations, flashes, files, datalogs, or anything in regard to the tune, tuning process, changes, are for OFF-ROAD USE ONLY NEVER TO BE USED ON A PUBLIC HIGHWAY. "

 

Actually 0058-18 Rev 1 does apply to the 2018, the first version excluded the '18s but it was revised to include them with Rev1. Funny enough it also applies to the B10,B11 and B12 ECUs (M/T). Know why? Cause it is mainly an update to the engine management side of things. The best part is that 0058 and 0062 are the EXACT SAME ECU program. It did some fine tuning to the trans with torque converter controls and such which helps with the smoothness that it shifts and how often it'll shift since it seems to allow for more slippage instead of doing as much of a shift dance as previous iterations of the trans programming allowed.
Yes, I'm aware of what the VW/Audi thing was about. I'm also don't kid myself in thinking that ANY of the car manufacturers are being honest with much stuff. Their job is to sell their product and to make it look as good as possible to the competitor who is also lying about his vehicle. The thing is that everyone....correct that A LARGE AMOUNT OF PEOPLE complain to Corporate about the shifting and the fact that they have released 4 different revisions to the trans yet it still shifts the same tells me that the shifting is what keeps Toyota compliant to the EPAs standards. NHTSA I don't think will have anything to do with the shifting issue cause there is nothing that is a safety concern besides the road rage that may occur from pissed off Tacoma drivers. The bad delay when you stomp the gas in 1st gear on the otherhand IS a safety issue to me but I don't suppose you bothered mentioning that to them. I'd recommend it. That feeling of going nowhere when trying to pull into traffic is truly frightening and a safety concern.
I won't be surprised that this trans gets put into or is already in use with Lexus vehicles as this motor is already in a few models. Thing is that you won't get the same blowback that you get from Toyota cause these are car motors and trans that are being used in a truck application of which Lexus has none. It works fine in a sporty car. Put a more torquey motor in this truck and a lot of the problems would disappear. Get rid of the double overdrive on our trucks and the problem would disappear. Combine a higher revving car motor with a double overdrive trans and an ECU programmed to shift as early as possible to meet EPA requirements and....here we are. If you want to compare apples to apples though then you can mention the HPFP the sounds like crickets under the hood at idle. Lexus owners complained about it, Tacoma owners complained about it, Sienna owners complained about it, Camry owners, Highlander owners, hell, even Scion owners were complaining about it back in 2013 and Toyota FINALLY listened and put out a TSB this year, not a recall cause it's not a safety issue, just another annoying thing that people complain about. My truck does the chirp real bad, embarrassing in traffic and drive thrus.
again, it's not that I disagree with the trans being shitty, it's the platform that you are using as your basis that is flawed and will cause you issues. The shifting is not an EPA or NHTSA issue and the TSBs do not mention shifting as something the fix so your Lemon Law is out the window too
@1911tex I stand corrected. Not everyone. A large portion is more accurate hence the reason you will find that most people that got the OVtune was to fix the shifting issues and the numerous threads on the various TSBs to address the trans with most people hoping the TSB would fix the shifting above all. There have been a handful of people that have said their truck shifts normal but then again, they get the OVtune or TSB done then say how much better their truck runs and shifts...maybe they just don't understand that just because the trans doesn't piss you off daily that maybe it could still be better.

I'm sorry you don't have $700? Best money I spent on this truck right next to getting 4.88s which also help out immensely with the trans driveability but is a bit more costly.
Not sure what the complaint is about the oil besides that you shoulda asked them for the other .8 quart, you paid for it. lol

 

@inksin lol yeah I thought about doing that but they would probably charge me more for a container to put it in as they have a big drum of oil that they pump from

 

come on man, you're smarter than them, bring an empty oil quart bottle next time with duct tape on the outside that says "Toyota Gold" on it then mumble to your service adviser that "only the finest of bitches can drink from this quart"

 

lol...... I love that I might have to do that

 

I just had the TSB done and I did notice a difference. The throttle response seems to be a lot quicker. Before it would lag a little while speeding up to switch lanes on the highway. That’s when I noticed it the most.

I have a camping trip this weekend so I’ll see how it drives through the mountains.

 

Let me know how it runs in the mountains last time I was there it would downshift on its own when I was coming down the mountains this was a few months ago. I’ve done the tsb this past Tuesday, which Toyota tried to charge me 44.95 to do it. Oh and I plan on going to the mountains later this month or maybe next month

 

62 fixed my truck.
If I'm super careful I can get the posted epa ratings with a modded truck.

Sorry your truck sucks.

As a former dsg owner, that tranny was way better than the taco. But that's not really a fair comparison.

 

I figured I would report back after altering my driving habits post TSB. I thought my truck was starting to stumble a bit and that the throttle response was not what it first was after the TSB so I decided to drive the crap out of it for a couple of weeks. The throttle response is now very good considering this is a small V6 in a heavy midsize truck. My mileage post TSB went up to about 22 but now it’s down to around 20, likely because of my newfound driving habits and slightly heavier foot.

 

Former, current, and future DSG owner here. Like you said, not a fair comparison. In fact, it doesn’t even belong in this conversation as we are talking apples and passion fruit (oranges just don’t do it).

 

Yup, driving aggressively for a while or disconnecting the battery to reset the learning and then driving the shit out of that seems to do the trick.

I haven't done it in a while, feels great now.

 

Mine is driving great now. I’m happy.

 

Different issue I think, I'm not talking lag, I'm talking NOTHING happens. you pull out and floor it and all you do is sit still. Doesn't feel like I was hauling a load, felt like someone turned the truck off.
In any regard, I hope you get something done with Toyota, it would benefit everyone for sure. Maybe your approach won't end up at the same dead end that all the others who have tried.

 

Actually it says right on the Tacoma tune page that it passes "all federal and Toyota emissions regulations". Just FYI

 

Yes, but very clearly non-highway use only in the disclaimer.

 

After the TSB, mine drives great. Before the TSB, drove like crap.

 

it's a standard disclaimer to limit liability from the dumbass sue happy tard that crashes his truck then decides to look for some deep pockets to blame for his own ineptitude. "the extra 25 horsepower made me crash" will inevitably be the basis of a lawsuit although any real driver knows that wouldn't happen. .....maybe in a car with 200 extra horsepower (which Matt also tunes)
It's just easier to use the standard disclaimer for everything.
It shouldn't bother you the least bit unless you plan on suing Matt at some point?
