Operation and Shifting Techniques

Proper shifting techniques ensure smooth operation and extended transmission life.

Starting: Depress clutch fully, shift to 1st gear, gradual throttle release
Upshifting: Smooth clutch engagement at 3000-4000 RPM for optimal power
Downshifting: Rev-matching recommended for smooth gear engagement
Reverse Engagement: Complete stop required, lift reverse lockout collar
Hill Starts: Use parking brake for steep inclines to prevent rollback

WARNING! Do not rest hand on shift lever while driving to prevent premature wear.

Maintenance Schedule

Transmission Fluid Change: Every 30,000 miles or 3 years
Clutch Fluid: Inspect every 15,000 miles, replace every 45,000 miles
Clutch System Bleeding: Every 60,000 miles or if spongy pedal feel
Shift Linkage Inspection: Every 15,000 miles for proper adjustment
Transmission Mounts: Inspect every 30,000 miles for wear
Clutch Disc/Pressure Plate: Replace at signs of slippage or 100,000 miles typical

Fluid Requirements

Use only Acura-approved manual transmission fluid for optimal performance.

Fluid Type	Specification	Capacity
Manual Transmission Fluid	Acura MTF or equivalent	2.2 quarts (2.1L)
Clutch Fluid	DOT 3 or DOT 4 Brake Fluid	As needed
Differential Fluid	Acura Dual Pump Fluid II	0.9 quarts (0.85L)

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

Clutch System

Hydraulic clutch system provides smooth engagement and consistent pedal feel.

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

Pedal Free Play: 0.4-0.8 inches (10-20mm) at pedal pad

Clutch Engagement Point: Mid-travel position for optimal control

Bleeding Procedure: Two-person method recommended; bleed until air bubbles disappear

Troubleshooting Common Issues

Symptom	Possible Cause	Corrective Action
Difficulty shifting	Low fluid, worn synchros	Check fluid level, inspect synchronizers
Grinding noises	Worn clutch, damaged gears	Inspect clutch system, check gear teeth
Clutch slippage	Worn disc, hydraulic issues	Replace clutch components, bleed system
Vibration in gear	Worn mounts, CV joints	Inspect mounts, check axle condition
Stuck in gear	Shift linkage binding	Lubricate linkage, check cable adjustment

Driving Tips

Maximize performance and transmission longevity with proper driving techniques.

Avoid "riding" the clutch - keep foot off pedal when not shifting
Use rev-matching for smooth downshifts - blip throttle before engagement
Allow transmission to warm up in cold weather before aggressive driving
Use engine braking on descents rather than constant brake application
Avoid aggressive launches and clutch-dumping to prevent drivetrain shock

Warranty Information

Transmission covered under Acura New Vehicle Limited Warranty: 4 years/50,000 miles. Clutch components considered wear items with 12-month/12,000-mile coverage. Extended warranty options available through Acura Care Protection Plan.
