Operation and Shifting Techniques

Proper shifting techniques for optimal performance and transmission longevity.

Startup: Depress clutch fully before starting engine
Shifting: Smooth, deliberate movements between gears
Rev-matching: Recommended for downshifting to reduce wear
Skip-shifting: Possible from 1st to 3rd or 4th to 6th for fuel economy
Reverse: Complete stop required before engaging

WARNING! Do not rest hand on shift lever while driving; avoid forced shifts.

Maintenance Schedule

Transmission Fluid: Replace every 30,000 miles or 2 years
Clutch Fluid: Inspect every 15,000 miles, replace as needed
Shift Linkage: Lubricate every 30,000 miles
Clutch System: Inspect every 15,000 miles
Differential Fluid: Replace every 30,000 miles
Transmission Mounts: Inspect every 30,000 miles

Fluid Requirements

Use only recommended fluids for optimal performance and longevity.

Transmission Fluid: Honda Manual Transmission Fluid (MTF) or equivalent

Capacity: 2.6 quarts (2.5 liters)

Differential Fluid: Same as transmission fluid

Clutch Fluid: DOT 3 or DOT 4 brake fluid

CAUTION! Using incorrect fluid may cause shifting issues and transmission damage.

Clutch System

Hydraulic clutch system with self-adjusting mechanism.

Clutch Type: Single dry disc with diaphragm spring
Operation: Hydraulic, no cable adjustment required
Pedal Free-play: 0.4-0.8 inches (10-20mm)
Fluid Reservoir: Shared with brake system
Bleeding: Required during fluid replacement or air intrusion

Tip: Avoid riding the clutch pedal to extend clutch life.

Limited Slip Differential

Helical-type limited slip differential for improved traction.

Type: Torque-sensing helical gear design
Operation: Automatic torque distribution to wheel with traction
Maintenance: Uses same fluid as transmission
Benefits: Improved cornering and traction in adverse conditions

WARNING! Use only recommended fluids to prevent differential damage.
