Gear Operation

Proper shifting technique ensures smooth operation and extends transmission life.

Fully depress clutch pedal before shifting gears
Move shift lever firmly but smoothly into desired gear position
Release clutch pedal gradually while applying throttle
Use rev-matching technique for downshifting
Avoid resting hand on shift lever during normal driving

WARNING! Do not force the shift lever into gear. If resistance is felt, return to neutral and try again.

Clutch System

The hydraulic clutch system requires proper maintenance for optimal performance.

Check clutch fluid level monthly in reservoir
Bleed system if clutch pedal feels spongy
Replace clutch fluid every 30,000 miles
Inspect clutch disc and pressure plate at 60,000-80,000 miles
Adjust clutch pedal free play if necessary

CAUTION! Avoid riding the clutch pedal as this causes premature wear.

Shifting Techniques

Master these techniques for improved driving experience and transmission longevity.

Smooth Upshifts: Coordinate clutch release with throttle application
Rev-Matching: Blip throttle during downshifts to match engine and transmission speeds
Double-Clutching: Useful for smoother downshifts, especially when cold
Hill Starts: Use parking brake to prevent rollback
Engine Braking: Use lower gears to assist braking on descents
