I put mine up (4) 12K lb Rhino ramps

I use ramps when I can for car maintenance (because so easy) but for this I used 4 jack-stands as it allowed me to compensate for my leaning driveway and get the GX pretty darn level.

Just a few weekends ago I did my first pan drop/clean, filter change, 12qt. flush (via trans warmer), and trans cooler install.
2016 Lux w/ 120k.
The old ATF was dark but obviously still red, didn’t seem burned, and magnets had just a little metal fuzz on them. Oil pan cleaned up very nicely.

Strong work!! That's my go-to procedure as well. Do you know if that's the first full fluid change for your car?

Putting up front on stands will drains double the “usual/level” amount, to 4-5qts - very helpful!!

Prior to me, no indication of trans fluid drain or flush. Single owner, all major service done at a single Lexus dealership.

However, right after I purchased it, I had the 120k severe service performed at a Lexus dealer (118k at the time) and they did a drain and fill. Charged me for 4 qt. of WS, so I assume ~3.5 qt. of fresh WS made it in there.
(After this, I went deep down into the rabbit hole of CL and Mud and decided on a full DIY pan drop, filter, flush, and cooler.)

Not sure what the true condition of the ATF was prior the 118k drain and fill but I'm assuming if it was torched, I'd have seen some good evidence in what I flushed out.

Unless I start towing a bunch, I think I'll skip the pan drop and filter replace for another 120k and just do drain and fills every 30k or full flushes every 60k. The full pan drop and filter change is not hard but time consuming and messy (snugging and torquing all 20 pan screws was annoying!) and based on what I saw in there, I'm not all that worried.

That's more than I would've thought. Just over 5 qt. is what ended up coming out from the drain, pan drop, and filter removal, and quite a lot was still in both the pan and the filter.
UPDATE: Looking back through my notes, just over 3 qt. came out from the drain plug with the GX level, and another 2 qt. came from the pan and filter.
Seems like the tilt 'n drain method has some merit!
