Anyone Had the TSB-0111-22 Update Done Yet? 2022 Tundra Transmission Hesitation

Perry Parts V3 Bump Stops - I am fully sold

I had the opportunity to be one of the early testers for the new bump stops from Perry Parts. There’s a lot that makes these bump stops different, and I want to be clear up front: these are not the same bump stops currently listed on the website. The new gen is a whole new design altogether. First thing you notice is size. These bump stops are much larger, they’re tuneable, and they’re designed to expand with your build over time instead of being something you replace later. The biggest design change is how they’re built. There’s a base section, and then the attachable bump stop itself. The base stays the same, while the bump stop can be changed out for a larger version, different materials, and more options in the future. The idea is that the bump stop grows with your build instead of being an afterthought. For example, if you start with a 3-inch lift and later move to a 6-inch lift, you won’t need to redo everything. You’ll just be able to screw on a different bump stop and keep moving forward. The design of the bump stop itself is honestly pretty genius. By using 3D printing, they’re able to build internal air channels and chambers that you just can’t easily do with injection molding. It’s not just about the material compressing—the bump stop is actually moving air in and out, which adds another level of tunability when it comes to controlling suspension travel. To top it all off, the packaging, instructions, and overall experience were just nice. You can tell this is an American-made company that actually cares. A lot of parts show up thrown in a box with a packing slip and maybe a sticker. These didn’t feel like that. It felt like someone actually took pride in what they were sending out. I’ll share more once I get some more time on them, but so far I’m pretty stoked on the direction Perry Parts is going with these.

So Toyota dropped TSB-0111-22 back in Dec 2022. It’s supposed to address the transmission hesitation and surge issues some of us have noticed when taking off from a stop. From what I gather, the fix involves an ECU/TCM software update at the dealer. I have some follow up questions to this.

How do we know if the truck has already gotten the update? Is there away to tell in infotainment? Or is a VIN check the only way?

Also....
Anyone here already get the TSB applied?
Did it actually improve drivability?
Any downsides after the update?

Seems like Toyota is aware of the hesitation complaints, but curious to hear real-world results from other owners before I book an appointment.
