2006 Ford F-150 • 6 cylinder 2WD Manual • 80,000 miles

Enter your question.I drive a 2006 Ford F150 4.2L 6 cyclinder truck and the clutch pedal isn't working. I filled the clutch fluid reservoir and tried pumping the pedal to no avail. It still loses pressure after driving a little ways. What else should I check or do?

This sounds like you might have either a failed master or slave clutch cylinder. Inspect the underdash area for fluid leakage at the master cylinder, although I suspect the slave is the culprit. It's inspection is more involved.
