How much transmission fluid does a 2018 Ford Fusion take?

9 quarts as a total fill for the 6F55 transmission (4.8 to 9 quarts across this year's engines). A drain-and-refill without removing the pan replaces roughly a third to half of that, so refill to the level check point rather than pouring in the whole figure.
