TSB: 2024 Tacoma Transmission Failures Issue & Replacement (9/9/24). Updated w/ VIN Lookup Tool

[TacoFreak]

@OlafTheNork That is the same for me - driving on mostly level roads, at 65-70 mph only gives me 17.2 mpg. I am also starting to have hard shifts, so I guess the failure process has started. Now to see where it leads. Good luck to all.

I don't want to spread unnecessary concern, just my experience. Not sure if it had anything to do with it, but most of my driving was in the "Eco" mode and got 19 mpg +/-. Since replacing the transmission I've run in "normal" and have been getting 23 - 25 routinely.

@Dirt I understand and I am not trying to spread FUD either, just trying to get a better understanding of what is going on.

That is a big change in mpg though and fits with what I am seeing. I had not seen that reported before and find it interesting. I just want to have as much warning as possible that my transmission might be on its way out.

Thanks for the input.

UPDATE - use this VIN lookup tool to determine if your VIN is affected by this TSB:

Here it is guys, official technical service bulletin for the codes that relate to transmission failure.

**UPDATED WITH PRODUCTION CHANGE EFFECTIVE VINs**

Steps to figure out if your VIN is in the TSB (by @taco_overlander).​

​

1. your VIN is an exact match to the letters and numbers to the left of the "#" in the TSB list​

2. your VIN has a number to the right of the "#" that is less than the number in the matched line found in 1.​

​

If you can do both 1. and 2., your VIN is in the TSB​

You do not fall under the TSB


I see this message. Is my Tacoma affected by the transmission problem or not? What should I be concerned about?

 

[Chewmeista]

other than a stuck gear and bad mpgs, has there been any other signs leading up the transmission failures?

my Trailhunter has officially hit 850 miles , my 1 ,2 shift still hits hard EVERY time I time I take it out to drive. After it seems to run normal , mpg im getting around 17.5- 18 mpg. I did notice that if I start the truck and engage it into "sport" mode the shift does not hit. It is only when the truck is in "sport" or "eco" . I do get sudden jerks at a stop light from time to time, I plan on taking it into my local dealer and getting the oil change at 1000 miles and asking them to change the transmission fluid.

@SP4RUNNER You truck's poor shifts and low fuel mileage sound a lot like my Pro. I am starting to think that damaged transmissions are pretty common in 4th gens, and obviously the problem was not fixed by the time that they started to build the halos. Last week my truck added a new one when it slammed hard into reverse after it was fully warmed up.

It will be interesting to see if your dealer will change your transmission fluid and if that makes a difference. I will talk to mine the first time I take it in and see what they have to say. I hope they are working three shifts at the transmission factory, because they are going to need a lot of replacements in the pipeline.

Good luck!
