Transmission Features

Advanced manual transmission system with performance enhancements.

Short-throw shifter: Reduced shift travel for quicker gear changes
Limited-slip differential: Improved traction and cornering stability
Rev-matching: Automatic throttle blip on downshifts
Hill start assist: Prevents rollback on inclines
Aluminum shift linkage: Lightweight and precise shifting feel

NOTE: Always depress clutch fully when shifting to prevent gear damage.

Driving Operation

Proper manual transmission operation techniques.

Starting: Depress clutch fully, shift to neutral, start engine
First gear: Clutch in, shift to 1st, gradual clutch release with throttle
Upshifting: Release throttle, clutch in, shift up, clutch out smoothly
Downshifting: Clutch in, shift down, rev-match, clutch out
Reverse: Complete stop, clutch in, lift reverse lockout, engage reverse

WARNING! Do not rest hand on shifter while driving; avoid riding clutch.

Maintenance Schedule

Every 30,000 miles: Inspect clutch fluid level and condition
Every 60,000 miles: Replace manual transmission fluid
Every 15,000 miles: Check shift linkage for wear and adjustment
Every 100,000 miles: Inspect clutch disc and pressure plate
As needed: Bleed clutch hydraulic system if spongy feel develops

Fluid Requirements

Manual transmission fluid specifications and replacement procedure.

Recommended Fluid: Honda Manual Transmission Fluid (MTF) or equivalent 75W-85 GL-4

Warm transmission to operating temperature
Remove fill plug first, then drain plug
Drain completely and replace drain plug
Fill until fluid reaches bottom of fill hole
Replace fill plug and torque to 36 ft-lbs

CAUTION! Use only GL-4 rated fluid; GL-5 can damage synchronizers.

Clutch System

Hydraulic clutch operation and maintenance.

Components: Master cylinder, slave cylinder, clutch disc, pressure plate, throwout bearing

Clutch pedal free play: 0.4-0.8 inches (10-20mm)

Fluid type: DOT 3 or DOT 4 brake fluid

Bleeding procedure: Fill reservoir, attach tube to bleeder, open bleeder, depress pedal, close bleeder, repeat until air-free

Shift Linkage

Shift mechanism adjustment and maintenance.

Inspect shift cables for wear and proper routing
Check shift lever bushings for excessive play
Verify neutral gate alignment
Lubricate pivot points with white lithium grease
Adjust shift cable ends if shifting feels imprecise

Tip: Rough shifting may indicate worn linkage components or low fluid.

Performance Tips

Optimizing manual transmission performance and longevity.

Allow transmission to warm up before aggressive driving
Use rev-matching for smoother downshifts
Avoid "power shifting" (shifting without clutch)
Don't use transmission to slow vehicle (engine braking moderate only)
Keep clutch fluid clean and free of moisture

WARNING! Aggressive shifting can damage synchronizers and gears.

Common Issues

Typical manual transmission concerns and solutions.

Issue	Description
Grinding gears	Worn synchronizers or low fluid level
Difficulty shifting	Worn clutch or hydraulic issues
Shifter vibration	Worn linkage bushings or engine mounts
Clutch slippage	Worn clutch disc or contaminated surface
Fluid leaks	Seal failure or case damage

Warranty Information

Acura provides 4-year/50,000-mile basic warranty and 6-year/70,000-mile powertrain coverage. Transmission components covered under powertrain warranty. Clutch considered wear item with 12-month/12,000-mile coverage. For warranty claims, contact Acura dealer with VIN and service records.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Hard to shift into gear	Low fluid, worn clutch, linkage issue	Check fluid level, inspect clutch, adjust linkage
Grinding during shifts	Synchronizer wear, incorrect fluid	Replace fluid, inspect synchronizers
Clutch pedal feels spongy	Air in hydraulic system	Bleed clutch system, check for leaks
Shifter loose or sloppy	Worn bushings or cables	Replace shift linkage components
Transmission noise in neutral	Input shaft bearing wear	Inspect bearings, replace if necessary
