Operation Guidelines

Proper manual transmission operation ensures longevity and optimal performance.

Starting procedure: Depress clutch fully, shift to neutral, start engine.
Shifting up: Accelerate to appropriate RPM, depress clutch, shift smoothly to next gear.
Downshifting: Match engine RPM with gear speed, use heel-toe technique when braking.
Reverse engagement: Come to complete stop, lift reverse lockout collar, engage gently.

WARNING! Do not rest hand on shift lever while driving; avoid riding the clutch.

Maintenance Schedule

Regular maintenance ensures transmission reliability and performance.

Fluid change: Every 30,000 miles or 2 years - drain and refill with specified fluid.
Clutch inspection: Every 15,000 miles - check pedal free play and hydraulic system.
Shift linkage: Every 20,000 miles - lubricate and adjust as necessary.
Transmission mount: Inspect every 30,000 miles for wear or deterioration.

CAUTION! Use only recommended fluids; improper lubrication can cause damage.

Fluid Requirements

Type: Honda Manual Transmission Fluid (MTF) or equivalent 10W-30 motor oil
Capacity: 2.4 quarts (2.3 liters)
Change Interval: 30,000 miles or 2 years
Drain Plug Torque: 36 lb-ft (49 Nm)
Fill Plug Torque: 29 lb-ft (39 Nm)
Fluid Condition: Clear amber when new; replace if dark or contaminated

Clutch System

Hydraulic clutch system with self-adjusting mechanism and wear compensation.

Components: Master cylinder, slave cylinder, clutch disc, pressure plate, release bearing.

Clutch pedal free play: 0.4-0.8 inches (10-20mm). Hydraulic fluid: DOT 3 or DOT 4 brake fluid. Bleeding procedure: Depress pedal slowly, open bleed valve, close valve, release pedal. Clutch lifespan: Typically 60,000-100,000 miles depending on driving habits.

Shifting Techniques

Advanced shifting methods for optimal performance and smooth operation.

Rev-matching: Blip throttle during downshifts to match engine and transmission speeds.
Double-clutching: Optional technique for smoother downshifts in older vehicles.
Power shifting: Not recommended - can cause transmission damage.
Cold weather operation: Allow transmission to warm up with gentle shifting initially.

Tip: Practice smooth clutch engagement to prevent drivetrain shock.

Common Issues

Typical manual transmission concerns and their indications.

Gear grinding: Worn synchronizers, low fluid, or improper shifting technique.
Difficulty shifting: Bent shift linkage, contaminated fluid, or clutch issues.
Transmission noise: Bearings, gear wear, or insufficient lubrication.
Clutch slippage: Worn clutch disc or pressure plate problems.
Fluid leaks: Damaged seals, loose bolts, or cracked housing.

WARNING! Address transmission issues promptly to prevent further damage.

Performance Tips

Enhancing manual transmission performance and driving experience.

Short-throw shifters: Reduce shift throw by 30-40%. Transmission mounts: Upgrade for reduced drivetrain movement. Fluid upgrades: Synthetic transmission fluids for improved shifting in extreme temperatures. Shift bushings: Polyurethane replacements for more precise feel.

Warranty Information

Standard warranty coverage: 3 years/36,000 miles basic, 5 years/60,000 miles powertrain. Clutch components considered wear items with 12-month/12,000-mile coverage. Keep maintenance records for warranty validation.

CAUTION! Modifications may void warranty; consult dealer before alterations.

Technical Service

Professional service procedures and technical specifications for certified technicians.

Transmission removal: Requires engine support fixture and special tools. Gear replacement: Complete disassembly necessary for internal repairs. Shift fork adjustment: Critical for proper gear engagement. Bearing preload: Precise measurement required during reassembly.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Hard to shift into gear	Low fluid, worn clutch, linkage issue	Check fluid level; inspect clutch system; adjust linkage
Gear popping out	Worn shift forks, detent springs	Inspect internal components; replace worn parts
Grinding noises	Worn synchronizers, incorrect fluid	Replace synchronizers; use specified fluid
Clutch vibration	Warped pressure plate, misalignment	Replace clutch components; check alignment
Fluid leaks	Seal failure, cracked case	Replace seals; repair housing as needed

Reset: No electronic reset required for manual transmission.

Service: Contact Acura dealer or certified transmission specialist for repairs.
