    Does anyone have info on if the 2021 Tacomas are coming from the factory with the transmission shift points already corrected per the recent TSB?

    So far, each MY has their own ECU IDs. The 2016s have several different TSBs to update the ECUs. The 2016s and 2017s group together which makes things a bit easier and is unlike the rest of the MYs since.

    At this point, the 2020 AT was 04A81 in late production with a TSB released to update the 04B80 Tacos. The 2020 MT was 04B91 in late production, but no TSB yet for the 04B90 folks.

    The 2021 ATs are 04C00 and 04C20. I believe 04C00 is MX. The 2021 MTs are 04C30.
