How much transmission fluid does a 2018 Subaru Crosstrek take?

11.3 quarts (10.7 liters) as a total fill for the TR580 CVT transmission. 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.

What brake fluid does a 2018 Subaru Crosstrek take?

Source: World's Best Oil (AMSOIL dealer cross-reference). Capacities are total system fills; a drain-and-refill takes less. Where no fluid specification is shown, the source lists only a catalog code, so use the specification printed in your owner's manual - the wrong transmission fluid damages a transmission.

Gear counts (for example "10-speed automatic") are from the U.S. EPA / DOE fuel economy listing for the same engine.
