1994 Ford Aerostar clutch slave cylinder

slave cylinder is internally mounted of tranny

Thank you,

When I went in my car to press the clutch, my clutch
went down to the floor. I look at the clutch fluid which is also brake fluid and it was empty. I was wondering is that a simple fix, too just refill, or do you have to do something else.

unless there is a leak somewhere then yes just refill it
