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

For what it's worth, I did the TSB last month and am very pleased. No more stumble, and power and acceleration seem to be smoother and more stable. Gas mileage took a hit, but it's like a totally different truck.

 

I checked my vin and that recall does not apply to my model ! Looks like I literally (DODGED) a bullet on that one. I guess I am just a (REBEL) LMAO . Thanks for the positive wishes lol . But in all seriousness I still have unfinished business with the Tacoma. When the Taco team puts in a power adjustable driver seat (so my better half can adjust it and drive when needed), puts in android auto and apple car play(so I can use and enjoy my infotainment system) and puts in a new engnine/transmission option( so I do not get ran over when trying to accelerate in traffic) I would like to give the Tacoma another shot. Maybe 4th gen in about 6 to 8 years. But for now I seriously love the Rebel and am glad I swapped it in .

 

I do think you are right sir, I don't think the organizer will fit on top.

 

So far I really like the rebel. Still getting used to the size difference but I really dig the way it drives.

 

Haha it's all good. I gotta give you some ribbing. Bottom line is you gotta do what you gotta do.

 

I had my dealer do the TSB 125-18 today and I think it has made a nice improvement over the stock tune. Everyone should do this the next time a trip to the dealership is needed.

I told them like the others did previously on this forum that it hunts for gears, slips, etc. etc... Thanks for your all’s experience and posting.

Side note, my dealership service department scratched my drivers side door today while doing this update. Previously I had them install my SCS wheels on my stock tires and they nicked my new wheels. They ended up buyin me a new one. I’ve never owned a Toyota before this 17 Tacoma, are all the service departments so careless?

 

Rule 1: never have toyota dealerships touch your wheels or tires if you care about them at least.

The only thing i trust them do is Oil change and most people on the forum dont even like that...

 

After years of the government convincing us that our children should be IT Nerds, coders, or human resource marketing analysts, there’s actuallly a huge shortage of qualified, skilled auto mechanics. A whole generation of mechanics is missing. The older guys with the skills are enjoying fat paycheques, good working conditions, and their pick of jobs, but there just isn’t enough of them. Your average dealership is now staffed by kids who were working at Subway last week.

 

The older guys are good at scamming single moms and old ladys on brake jobs and cabin filters..

 

Took my 2018 Tacoma with auto trans and 2.7 motor to The Newnan Toyota Dealer in GA ,would not do the tsb for me. My truck hunts for gears and when using cruise control it will down shift when it doesn’t need too. It also will down shift but will not up shift once i top the hill and go down the hill it will not up shift.

 

I saw that the tsb is for the v 6 trucks. But don’t the 4 and v6 trucks have the same trans? Looks like I have the same problems.

 

Tsb is technically for motor tune, not officially any transmission tune changes

 

Newnan is where I got mine done. No questions asked. They’ve always been great to me. I think it must not be for the 4 cylinders. I’m not 100% sure though.

 

Just so everyone knows I called Lagrange Toyota and they took my vin and said there is no tsb for the 4 bangers. If newnan would have told me this I wouldn’t had to argue with them. They were telling me it was my 2 inch lift that was causing my problems. Then I told them it was baloney then they said it was my Toyota trd rims with tires. So I call bologna on that too and told them that they were selling the same trucks with the same rims and same size tires so then they told me it was my exhaust and cold air intake then I just left the dealership.

TSB #T-SB-0062-18
NHTSA ID #10143932

• Date Announced: JULY 17 2018

Summary: TSB: Some 2016 2017 2018 model year Tacoma vehicles equipped with a 2GR-FKS engine and an automatic transmission may exhibit a stumble at wide open throttle takeoff during operation in a high-altitude area.

 

I had mine done last week while having blower motor recall done. Truck throttle response is so much better now.

 

What octane are you running now? I MUST get this ECU update but wondering if running 87 is part of the problem..

 

Running 87 is absolutely part of the problem. However i would say 85% of the issue is the transmission shift logic making your engine try to run at 1000 rpm. After the tsb, i notice it tries to stay above 1500 rpm, which helps a lot. Low rpm sputtering and missing has been solved with 91 octane. The detonation rattle at light throttle right before a downshift is also gone with 91 octane.

 

Thank you that’s very helpful. We have 93 octane here, otherwise would have to use 89. I’ve read that high octane fuel in engines built for lower octane can negatively affect an engine over a long period of time. Any truth to that IYO? Would 93 be too high? Also, the TSB you are referring to... Was it the 0062-18 that helped? Thx in advance

 

There is no harm in running 93. I have run it for 30k miles or so due to the low throttle miss. 89 probably would fix it as well, but I typically only have 87 or 93.
