According to the manual, we should change the Trans fluid at 60K. I'm around that milage now, so figured why not.
The procedure itself is fairly straight forward.
To drain the fluid, remove 24mm fill plug on pass side of trans, remove a 14 mm drain plug in the back of pan, and for good measure remove or at least crack open the overflow plug (5mm hex) in the front.
This process will drain approx 3 quarts of atf.
Now it's time to refill your transmission. Install a new overpriced crush washer on the drain plug, and tighten it (can't find torque info on it). Again, New washer on overflow plug, but this one just finger tight for now.
Now add you fresh ATF WS ( I used this pump ) 3-3.5 quarts should be quite enough.
And now it's time to check your atf level. For that, we have to bring up trans temp to *95°-113°F* Yep, that tight. Start your engine, let it warm up, and when your atf reaches that optimal temperature, it's time ( with engine running) to remove the overflow plug and drain the excess fluid. It should start quite heavy, and when it calms down to just a drip, replace the overflow plug (with a new washer) and tighten it to 15 lbs. You have only a few minutes before temperature gets too high.

And voila!! All done!
actually, I performed drain & refill process twice, just to add 3 more quarts of fresh atf. Not sure how much of a difference did that make besides adding some more time to the entire operation [/S]

*Edited an updated to values from Service Manual for 2016+ Tacoma
I use Scanguage to monitor the temperature.
There is a way to check it using TechStream or shorting pins #4 and #13 on obd and putting the cpu into Temp Check mode. Like this

Pretty similar to 2nd/4th gens. Need to check my levels since I added the transmission cooler.

So brother Bastek, notice any difference with the transmission after the fluid change?

I am at 70k and am planning on doing this over the summer so thanks for the thread.
