I did the latest update and no idea where to find transmission oil temperature. I even called Autel and they could not find it.
Autel scan tool users help please (can't find transmission oil temp)

On what make/model/trans car? They do not all have temp sensors.

It is not unusual to find scan tools not supporting all pids, occasionally you can find different pids in OBD2 mode that are not listed when you go in by make/model.
Most of the time however if they are not there they are just not supported by the tool, that is why you see shops using several different brands of scan tools with the best(and most expensive) always being the OEM tool solution for any given automotive brand.

Most scan tools won't support the trans temp PID that Toyotas have.
You can purchase any ELM327-compliant OBDII bluetooth dongle (~$20) and the OBD Fusion cellphone app ($5) and then the extra 'enhanced diagnostics' I think it's called ($10) for your model and it will display trans temps. Likewise you can do the same with the same type OBDII dongle and the Torque Pro app ($5) without the $10 addition but you'll have to do some googling Toyota forums &/or Torque Pro's forum to find the custom PID data you'll need to manually enter yourself to get it to work.
If you're only wanting to check trans temps so you can check fluid level on a Toyota sealed (no dipstick) trans after a drain and fill or a flush or whatnot Toyota has explained in their Factory Service manuals how to enter 'Transmission Temperature Check Mode'. It involves jumpering pins 4 and 13 in your OBD port and a slow shift sequence back and forth between Neutral and Drive for ~6 secs until the (D) drive indicator on your dash comes on for ~2 secs telling you that you have entered check mode. Then you wait idling until the light comes back on telling you that you have reached the Transmission temp check range for your model. When that happens you need to be ready & quick to open the overflow to check the level while it is still idling before that light starts blinking indicating it's gotten too hot out of check range. The details of how to do this are explained in many Toyota forums and Youtube vids.
EDIT: Here it is explained in the Factory Service manual for an earlier model. I strongly suspect it also applies to your 2021 as it has applied to previous models for about two decades now but I'd suggest checking your model's FSM or with AllData or Mitchell or by joining a Tundra forum to check with members there to be sure. Perhaps your dealer's service dept might be helpful in that respect too, or not.

I know for a fact that my BlueDriver with latest update can't monitor Toyota Trans temps, yet, even though a rep from them replied to me via email about a year ago now saying they were looking into adding it for select models including Toyotas because they get asked so much about it.
FWIW looks like the Autel Maxisys apparently does show Toyota's Trans temps in a live data PID judging by this video, at least for a 2008 4Runner...

I also use Torque Pro because it allows you to define custom PIDS. There are a lot of packages out there for different brands of cars. Gets you all kinds of additional data like the above mentioned transmission fluid temperature.
