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

[Delta1Seven]

@Gfenza89 Yep - I have had trucks which fell under several of them. I just didn't think that they would still be building trucks with transmissions in the TSB range. Isn't that kind of nuts? Maybe I didn't understand the situation and I don't think @Delta1Seven's dealer is being very helpful, for whatever reason. If it was me, I would at least want more info from the dealer.

BTW - yesterday my truck shifted just like normal. Did your issues come and go like that?

thanks for the idea. I will ask for more info. All they told me was that it was "in allocation" which they claimed doesn't have an accurate ETA. I assume this means pre/in production?

I find it weird that the VIN number is so low if the current trucks are higher. (Assuming VINS are sequential?)

EDIT: I'm new to "ordering" a tacoma. What exactly should I be asking? They have told me the ETA is 11/4 but then in the next breath they claim it's in allocation and the ETA isn't accurate. I feel like the salesman doesn't have a clue, and he is trying hard to get me into a limited on their lot, but I want a OR premium lol

I just updated the tracker.

Interestingly, the VIN i was giving by my dealer of a TRD OR that is in allocation, is not on your list despite it falling into the TSB range. Does that make sense?

That is what mine has started doing most days now too. I can live with that but it does make you wonder where this road is headed.

Any other symptoms?

tankk69 - I am new to this forum but had my transmission go out at 2500 mi. In looking at an earlier TSB the first letters were different in some of the affected VIN's. The numbers varied with those first letters as well. Bottom line, my impression is the whole string is important. BTW it took a little over a month to get my rig back up and running. With over 10K on it, the mileage is better and it works as expected.

What was the mileage when it failed?

literally says 2500mi in his post.

What's the vin you were given?

Not the last time I drove it. On some days it works perfectly and recently when it has had issues it has been a delayed and abrupt engagement of 2nd when going from 1st, which is usually only once when first starting to drive. It is abrupt enough to make the truck jump, like it was bumped from behind.

I also have that slight rumble when downshifting occasionally, maybe that is the 2nd gear solenoid also. Still waiting to see if this stuff changes or how it develops.

How does yours shift in and out of park, reverse, drive? Does your truck jump forward or backward?

Nope - at least not at this time. It shifts in and out of park, reverse, drive as I expect it to.

I mostly just have that delayed shift when I first start out, which seems like it almost has to be a problem with a shift solenoid. I have seen a lot of owners comment on having that. I think the transmission control unit says shift, but the solenoid takes a while to complete that. It isn't stuck so there are no codes, and I guess Toyota thinks this is normal.

Yeah makes sense which simply means there’s a problem… im really thinking more info from Toyota is coming soon. There are a lot of trucks out there in this vin range and a lot of possible failures for them to just let this go. Then there’s me who seems to have a trans that just won’t give up the ghost!

These are trucks currently in dealer inventories. Also, the list is not 100% accurate.

Well shit.. Maybe I’ll learn to read soon!

What was yours doing before and during its failure? Can you go into detail please to help the folks on this forum who are going through this? Check engine light on ? Thank you!

The only thing that really stood out was poor MPG's. A friend bought a similar TRD and was consistently getting 3 to 5 mpg better than I was. One afternoon I stopped at a red light, when it changed, my rig wouldn't move. I ran the shift selector from D to P and all other stops with no movement; went to the "manual" side and found it stuck in 6th gear, would not change out. Back in D out of frustration ran the RPM's up over 5K and just crept enough to get out of the traffic lane. Sat for a few minutes messing with the shifter without any noticeable changes. In D ran RPM up over 3K and we slowly moved off with a gravel on tinfoil sound. Drove about ten blocks at 20 - 25 mph to my mechanic, turned it off. Came back out about ten minutes later, started the rig, put it in Drive and it moved off like normal. Drove it two hundred miles to the dealer without an issue. When the service mgr had a Toyota tech drop the pan, brass particles were visible. A thought was that the particles plugged a sensor so the transmission didn't know it was supposed to move. Once the particles had a chance to drop off, the sensor worked.

Thanks for that post. I think a lot of us wonder what we might see leading up to a failure. Getting stuck in 6th gear seems to happen a lot.

Your post reminds me of something else I have seen with my truck, which is low fuel mileage. Even though my truck is still below 1k miles, its mileage is a lot less than I expected. My best drive so far was 17.2 mpg, all freeway. I thought maybe it's just breaking in, but now I wonder if mileage 5-7 below the EPA number is a sign of a transmission problem. Maybe it isn't able to shift into some higher gears or lock the torque converter?

Dirt and Tacofreak - thank you. This is great information and background. I have a Tacoma Pro/Hybrid w/1400 miles on it, and also experience the poor gas mileage. I barely got 20 mgp on the expressway, flat road, hypermiling. Now experiencing "hard shifts". So we'll see what happens going forward. I will post accordingly. Thank you again.
