How much transmission fluid does a 2006 BMW X3 take?

9.5 quarts as a total fill for the 5L40-E transmission (9.5 to 10 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.
