Drain change fluid in pan and filter use existing OEM gasket(replacement gaskets are rubber and can cause leaks) I dip a white paper towel fresh transmission fluid remove return line pump out old fluid out of TC. Check fluid coming out with paper towel and compare it to new fluid, when it looks the same just top off fluid and you are done.
If your old enough you've likely heard that flushing an older transmission can lead to it's demise, had it happen, blew inside of a week.
When experiencing discolored fluid, I simply find a return line and let the transmission pump out the old while I'm adding new....turns pink, your done.
When a transmission hasn't been neglected a simple filter change and refill has always been effective. Ymmv
