Installation and Setup

Professional installation recommended for transmission replacement or upgrade.

  1. Vehicle preparation: Secure vehicle on lift, disconnect battery, drain transmission fluid.
  2. Remove old transmission: Disconnect shift linkage, clutch components, and mounting bolts.
  3. Install new unit: Align input shaft with clutch, secure mounting points.
  4. Reconnect components: Attach shift linkage, refill with specified transmission fluid.
  5. Test operation: Check gear engagement and clutch operation before road testing.

WARNING! Transmission is heavy; use proper lifting equipment. Ensure all connections are properly torqued.

Operation Guidelines

Proper shifting technique ensures longevity and optimal performance.

  1. Clutch operation: Fully depress clutch pedal before shifting gears.
  2. Shifting sequence: Follow gear pattern indicated on shift knob.
  3. Rev matching: Match engine RPM to gear speed when downshifting.
  4. Reverse engagement: Lift reverse lockout collar before selecting reverse.
  5. Break-in period: Avoid aggressive shifting during first 500 miles.

CAUTION! Do not rest hand on shift lever while driving. Avoid forced gear engagement.

Technical Specifications

Controls and Interface

Shift pattern: Standard H-pattern with reverse in lower right position. Clutch pedal: Hydraulic operation with self-adjusting mechanism.

Shift Knob Indicators: Gear positions clearly marked. Reverse lockout requires lifting collar. Clutch pedal: Engagement point adjustable on some models. Shift feel: Precise, mechanical feedback with short throws.

Performance features: Helical cut synchronizers for smooth engagement, carbon-lined synchronizer rings, triple-cone synchronizer on 2nd and 3rd gears. Shift linkage: Minimal play for direct feel.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

  1. Transmission fluid: Replace every 30,000 miles or 3 years
  2. Clutch fluid: Inspect and replace as needed with brake fluid flush
  3. Shift linkage: Lubricate pivot points every 15,000 miles
  4. Clutch system: Inspect for wear every 60,000 miles
  5. Mounts and bushings: Check for deterioration during routine service

Tip: Use only specified manual transmission fluid for optimal performance.

Driving Techniques

Mastering manual transmission operation enhances driving experience.

  1. Smooth starts: Gradually release clutch while applying light throttle
  2. Rev matching: Blip throttle when downshifting to match engine and transmission speeds
  3. Hill starts: Use parking brake technique or quick foot transition
  4. Engine braking: Use lower gears to slow vehicle without brake wear
  5. Skip shifting: Direct shifts from lower to higher gears when appropriate
  6. Double clutching: Optional technique for smoother downshifts
  7. Cold weather operation: Allow transmission to warm up before aggressive driving
  8. Track driving: Learn heel-toe technique for performance driving

WARNING! Do not ride clutch pedal. Avoid excessive slipping during engagement.

Performance Features

Advanced engineering for enhanced driving dynamics and reliability.

Triple-cone synchronizers on 2nd and 3rd gears for high-RPM shifts. Carbon-lined synchronizer rings for consistent performance. Shot-peened gears for increased strength. Lightweight aluminum housing for reduced weight. Optimized gear ratios for specific power bands.

Care & Maintenance

Proper care extends transmission life and maintains shifting precision.

Use only specified manual transmission fluid. Check for leaks during oil changes. Avoid aggressive shifting when transmission is cold. Listen for unusual noises during operation. Have professional inspection if shifting becomes difficult.

CAUTION! Do not use automatic transmission fluid. Avoid contaminated fluid during service.

Warranty Information

Standard warranty: 3 years/36,000 miles from installation date. Covers manufacturing defects in materials and workmanship. Does not cover damage from improper installation, abuse, or lack of maintenance. For warranty claims, contact authorized Acura dealer with proof of purchase and maintenance records.
