Driving Your Shelby Gt500; Alternate Calibration; Transmission Operation - Ford 05+ Mustang 2008 Supplement Manual

Driving your Shelby GT500

ALTERNATE CALIBRATION

Your Shelby GT500 Power Train Control Module (PCM) strategy contains
a feature to limit supercharger boost pressure and engine speed to 4000
RPM for the first five consecutive miles of vehicle operation or 50 engine
start / warm up cycles. This feature is enabled prior to shipment. If
neither of these conditions have been satisfied prior to customer
delivery, full power will not be available.
MANUAL 6 SPEED TRANSMISSION OPERATION
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully depressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to 1st gear, then slowly release the clutch
pedal while slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Failure to fully depress the clutch pedal to the floor may cause increased
shift efforts, prematurely wear transmission components or damage the
transmission. Make sure the floor mat is properly positioned so it doesn't
interfere with the full extension of the clutch pedal.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Due to the high performance of the powertrain, a certain amount of
noise from the transmission is normal. This noise will be most noticeable
when the vehicle is idling in neutral with the clutch pedal out but can
also occur when driving away from a stop.
