Here's a link to my Partial Drain Calculator Spreadsheet.
You must dowload it for it to calculate for you, it is an EXCEL Worksheet. Dropbox will just show a preview.
I have seen to many people miscalculating the percents and numbers on partial drains and refills on their transmissions.
What folks commonly say is "if I drain 2 of 6 quarts over 3 times, heck I can have a full changeout by the tuird time..BEWARE! That's not the case... because of mixing, it wont be until the 7th fluid change that you actuially reach a 95% total new fluid.
I used university mathmatics people to design this spreadsheet which is verified as accurate. It gives you percentages, volumes of how much is now old vs. new, it tells you how many partial changes it will take to achieve your desire percent total of new fluid.
Perhaps a Sticky?
