Acura 6 Speed Manual Transmission

The Acura 6-speed manual transmission is a precision-engineered gearbox designed for performance vehicles, offering smooth shifting, durable construction, and enhanced driving engagement. This transmission features close-ratio gearing for optimal power delivery, synchronized helical gears for quiet operation, and a short-throw shifter for quick, precise gear changes. Below are key sections covering specifications, operation, maintenance, and troubleshooting.

Features at a Glance

Key components: Close-ratio gearset, short-throw shifter, synchronized helical gears, dual-cone synchronizers, aluminum housing.

Installation

Professional installation recommended. Ensure proper alignment and torque specifications.

1. Remove old transmission: Disconnect driveshaft, clutch cable, shift linkage.
2. Install new unit: Align input shaft with clutch disc, secure mounting bolts.
3. Connect components: Attach shift linkage, clutch hydraulic line, speed sensor.
4. Fill with specified transmission fluid.
5. Test operation: Check all gears engage smoothly.

WARNING! Transmission is heavy; use proper lifting equipment. Ensure all fasteners are torqued to specification.

Operation Guidelines

Proper shifting technique ensures longevity and optimal performance.

1. Clutch operation: Depress fully before shifting, release smoothly.
2. Shifting sequence: Use sequential pattern (1-2-3-4-5-6).
3. Rev-matching: Recommended for downshifting to reduce synchro wear.
4. Avoid forcing gears: If resistance is felt, return to neutral and retry.

CAUTION! Do not rest hand on shift lever while driving. Avoid aggressive shifting when transmission is cold.

Fluid Requirements

Use only specified manual transmission fluid for optimal performance.

1. Fluid type: Honda MTF or equivalent synthetic manual transmission fluid.
2. Change interval: Every 30,000 miles or 2 years under normal conditions.
3. Capacity: 2.2 quarts (2.1 liters) when dry.
4. Check level: With vehicle on level surface, remove fill plug.

Tip: Fluid should be at bottom of fill hole when transmission is at operating temperature.

Maintenance Schedule

Regular maintenance ensures long service life and optimal performance.

1. Fluid change: Every 30,000 miles or 2 years.
2. Clutch system: Inspect every 15,000 miles.
3. Shift linkage: Lubricate every 30,000 miles.
4. Mounts: Inspect for wear every 30,000 miles.
5. Seals: Check for leaks during oil changes.

WARNING! Use only specified fluids. Incorrect fluid can cause premature wear and shifting issues.

Troubleshooting

Service: Contact authorized Acura dealer for technical support and genuine parts.
