2003 FORD MUSTANG automatic transmission

The clutch control system engages and disengages the clutch. The clutch control system disengages
the clutch when the clutch pedal is depressed and engages the clutch when the clutch pedal is
released. Clutch pedal motion is transmitted by the clutch release lever cable to the clutch release
lever. The clutch release hub and bearing engages the clutch pressure plate diaphragm spring,
releasing the pressure on the clutch disc which in turn disengages the transmission from the engine.
The clutch adjusts automatically to compensate for clutch disc wear. The clutch linkage is self-
adjusting.
The clutch pedal position (CPP) switch prevents the starter motor from engaging unless the clutch
pedal is depressed all the way to the floor. The switch plunger is contacted by the clutch pedal and
extends as the clutch pedal is pressed. The clutch pedal position switch is electrically connected in line
with the ignition switch and the starter motor relay coil. The CPP also turns off the speed control when
the clutch pedal is depressed. 4 7L583 Clutch pedal quadrant and pawl assembly Klj . 2 ba
