92 corolla DX tranny, cable or hydrolic?

Well when i drive my mom's car, ive noticed that the clutch is slipping very bad on it, she told me she just recenlty put in a new clutch so i am guessing that the clutch just needs a little adjustment, does the 1992 corolla DX have a cable or hydro tranny? Do any of you know how to adjust the clutch if it is possible because it slips pretty bad on acceleration and shifting..thanks.
