I don't know if I would even use redline. I question it's use in this application. Just use A/T fluid as has been said multiple times. No additives necessary and may do more damage. I have V8 so I drain, fill, drive 10 miles, drain, fill, drive 10 miles, drain, fill and keep driving knowing I have exchanged almost 100% of the fluid. Don't known what difference it makes how much it holds because you are going to buy like 5 quarts for the multiple fill/drain procedure and if you have a bottle left or you need to get another bottle, who cares? A bottle of trans fluid on the shelf will get used eventually and save another trip to the store.
Since you have a V8, you should have a drain plug on the bottom of your P/S pump. This allows you to drain most of the fluid in one shot. You get a much more effective fluid change, and you only need to buy 2 quarts of Dex-VI.
