A few days ago I go in my car... take the ebrake off, clutch, and the car wont go in gear... ive heard things about clutches freezing, so I let the car warm up and pumped the clutch a lot... finally it let me get into gear.. and the car rode fine.... then today the same problem happened... s0o i warmed it up, pumped the clutch, and still it would only let me get into like 1,2 and 3rd gear. what am I looking at here? big problem or easy fix? btw the lude is a 98 base
