2022+ Transmission Fluid Drain + Fill + Level Check

Has anyone done a drain and fill on the transmission on a 2022+

I found one video showing the process but lacked the details (Torques/Temp range) and did not show pinning the thermostat open.

Anyone on here done it and have tips/specs to share?

Planning to do it shortly and share.

So far found:

- Fill 29 ft lbs
- Drain 15 ft lbs

Then i found a conflicting 30 ft lbs for both drain and fill bolts...

- 30ft lbs for both drain and fill

Level set temperature is 99*-109* Degrees F

 

How to change transmission fluid on a Toyota Tundra This is a 2nd Gen but shows pinning the thermostat open at 6:11 mark

2022+ Tundra Transmission Fluid Replacement - YouTube This shows a pretty good overview of a 2022+ but does not have torque/temps nor does it show pinning the thermostat if that is really necessary

 

Did it this morning. There does not appear to be any thermostat to pin open so that likely does not apply.

Used 5 quarts of fluid Toyota ATF WS. The washer for the transmission drain bolt is new and I've never seen it on any of my other Toyotas so i just reused it this time. Fill bolt washer is the typical washer used on the Toyota diff bolts I've seen.

Torqued the Fill plug to 30 ft lbs. And it felt right.
Torqued the Drain plug to 15 ft lbs and that felt right. I think you would strip the pan if you went up to 30...

I thought i had a scan tool that read transmission fluid however on this truck it did not show that option to read and track live data as it does on my older Toyotas. So i used the transmission fluid check mode by Shifting through P - R - N - D - P 3 sec each and then back and forth from N - D for 12 seconds until the D on display begins flashing... It was very simple. Had to let the truck idle for about 10 min to get up to temp. D came on solid and i went under to remove the check valve and let drain to slow trickle.

Fluid looked great for 49k miles. No sign of burning or irregular wear.

I'll probably do a drain and fill every 30k miles since its so easy.
