Impressions of shifting/hesitation/power TSB (T-SB-0092-20)

Good to know, I'm in the Bay Area but have family up that way. May just reach out to them and try and get it scheduled.

 

Only difference I can tell with ECT is that if you go past 1/4 throttle, you drop 1-2 gears and are placed right in the powerband.

 

I just had the TSB done and it definitely makes a major difference to the way the truck performs.

 

what dealer? My local shithead refuses to do ANY tsbs.

 

You can do this at home with less frustration. See the ECU Update thread.

 

I just had my '20 Pro updated to this TSB. The differences that I noticed are:

- It does feel like it holds gear longer down low and does not look to upshift as quickly.
- The biggest difference for me is cruising 65 -70mph it no longer gear hunts a soon as you hit a grade... it will hold the gear.

I was in the group that my Crawl Control did not work and after the TSB it still does not work like the previous years.

 

The dealer in Petaluma did mine. Oddly enough they won't do my fuel pump recall yet though.

 

Anyone have this tsb file to upload prior to ovtune?

 

See the ECU Update thread 1st Post. All available ECU TSB and CUWs are there.

 

Looked it was a link to pdf. I get access denied when I click on the computer number

 

I have no idea what you're saying here, but attached to the 1st Post are the US and CA TSBs being discussed here and the CUW files for the 2019s and 2020s:

 

In the TSB pdf there is a list of calibrations with a link to the new calibrations. The files are missing on the link to the new files

 

Those are not missing. They're on the TIS subscription, Toyota file system data. The other underlined ZIP files are those files. This is all detailed in the 1st Post. Which CUW goes with which TSB, Taco, and ECU ID.

Doing this update might not be for you? If you reach out locally, I'm sure some TW'er will help out.

 

lol your funny, judge much for asking a question. pdf doesn't state what calibration id's use t-0023-20 vs t-0022-20. I've flashed plenty of cars in the past, but also not smart to just flash without a lack of info to tie everything together.

 

As noted, all info is in the 1st Post:






If you're not going to read, you're gonna struggle. See it before.

 

Just a hint, you might want to relabel your initial post on the usb to state "spoiler: attached are the cuw files and description..." Seeing the files below not everyone will click it, but that is where the key information is.

 

so they finally tried to fix the hotmess of a transmission 4 years in?

I guess I should have waited

 

I had mine done yesterday. No problem with getting it done. Just asked for it and showed them a copy of the tsb.
I could notice the difference as soon as I pulled out of the dealership. It feels like it has a little more power when taking off and getting up to speed. Or I should say the transmission makes better use of the power the engine has. Has a somewhat similar feel as when driving with the ECT Power button on but in a lesser way. Seems to be keeping the transmission out of 6th gear, at least with speeds up to 50mph as I havent been on a highway yet.

 

Makes me wonder if I was too hasty in ordering OVTune this week
