Upshifting: Clutch in, shift to next gear, smooth clutch release.
Downshifting: Clutch in, shift to lower gear, rev-match if desired.
Reverse: Complete stop, clutch in, press down and left to engage.

WARNING! Do not force gears; ensure complete clutch depression before shifting.

Clutch System

Hydraulic clutch system requires periodic inspection and maintenance.

Clutch pedal: Check free play (10-15mm at pedal).
Fluid level: Inspect reservoir monthly; use DOT 3 or 4 brake fluid.
Bleeding: Required if air in system or spongy pedal feel.
Wear indicators: Slipping, grabbing, or difficulty shifting.

CAUTION! Avoid riding clutch; replace if pedal engages near floor.

Maintenance Schedule

Transmission Fluid: Replace every 30,000 miles or 2 years.
Clutch Fluid: Inspect monthly; replace every 2 years.
Clutch Assembly: Inspect every 60,000 miles; replace as needed.
Shift Linkage: Lubricate every 15,000 miles.
Transmission Mounts: Inspect every 30,000 miles.

Capacity: Transmission requires 2.2 quarts (2.1 liters) for complete refill.

Shifting Techniques

Master proper shifting for performance and durability.

Smooth Shifting: Complete clutch engagement, smooth transitions between gears.

Rev-Matching: Blip throttle during downshifts for smoother engagement.

Hill Starts: Use parking brake for assistance on steep inclines.
