transmission fluid change procedure

[Russianblue]

I'd like to do the multiple change method where I drain it two or three times to get all the fluid from the torque converter.

1. can multiple fluid changes all be done in one or two days (over a weekend)? how much driving between fluid changes is required to sufficiently blend all the new oil and circulate all the oil in the torque converter?

2. do you have to replace the gasket and or bolts all three times? I've seen plenty of DIY's and videos for the partial fluid change but very little documentation of the full 3x fluid replacement.
