I'm curious that you do the filter AFTER the first two drain/fill cycles... I read that you dont want to run your 80% new ATF through an old filter and contaminate it, better to run 20% old through the new filter and do the first drain / fill after a really short cycle (few minutes shifting through all gears) then the 2nd drain / fill after a longer one... what is your experience, opinion?
