1st ATF replacement due

just curious what's the 'proper' way to approach this alternative to a tranny flush

i've seen many different methods suggsted online

1. after first fill, drive few times around the block going through the gears, drain & refill & repeat 2x

2. a week of driving in between the drains & refills

3. wheels off, run it through the gears for few miles. Is just shifting continously adequate or do I have to bring it to a typical rpm per gear? (is this even safe on jack stands?)

is all this necessary or would a single D&R be enough? I already bought 9 quarts of ATF-DW1 so it's not so much a financial concern as but moreso the perception of wasting fresh fluids

car shifts fine, would comparing fluid colour/smell/presence of metal be good enough of an indicator to follow through with the 3x? Or just do it for a peace of mind?

Also annoyed at coolant fill not needing 2 full gallons....and probably won't keep the excess around because shelf life...what a waste. It's already 50:50 and it's got a big do not add water label.
