Proper Shifting Techniques

Mastering proper shifting techniques ensures smooth operation and extends transmission life.

Starting from Stop: Release clutch smoothly while applying gentle throttle.
Upshifting: Lift throttle completely, depress clutch fully, shift quickly but smoothly.
Downshifting: Rev-match by blipping throttle while shifting to lower gear.
Skip-Shifting: 1st to 3rd or 2nd to 4th for fuel economy.
Reverse Engagement: Lift collar on shift knob before moving left and up.

WARNING! Do not rest hand on shift lever while driving as this can cause premature wear.

Clutch System Operation

The hydraulic clutch system provides consistent pedal feel and engagement characteristics.

Component	Specification
Clutch Disc Diameter	225mm
Clutch Type	Single dry disc with diaphragm spring
Fluid Type	DOT 4 Brake Fluid
Master Cylinder Diameter	15.87mm (5/8 inch)
Slave Cylinder Diameter	19.05mm (3/4 inch)
Pedal Free Play	5-15mm at pedal pad
Clutch Engagement Point	Approximately 1/3 from floor

CAUTION! Avoid riding the clutch pedal as this causes excessive heat and wear.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity of the manual transmission system.

Every 30,000 miles: Inspect clutch fluid level and condition
Every 60,000 miles: Replace manual transmission fluid
Every 15,000 miles: Inspect clutch pedal free play and adjustment
Every 7,500 miles: Check for transmission fluid leaks
As needed: Inspect shift linkage and bushings for wear

NOTE: More frequent maintenance may be required for severe driving conditions.

Fluid Requirements

Using the correct fluids is critical for proper transmission operation and longevity.

Transmission Fluid: Honda MTF (Manual Transmission Fluid) or equivalent
Fluid Capacity: 2.1 quarts (2.0 liters)
Clutch Fluid: DOT 4 Brake Fluid
Fluid Change Interval: 60,000 miles or 60 months
Fluid Type Specification: API Service GL-4 or higher
Viscosity: SAE 10W-30 or manufacturer-approved equivalent

WARNING! Do not use automatic transmission fluid or gear oils not specified for manual transmissions.

Common Operating Characteristics

Understanding normal operating characteristics helps distinguish between normal behavior and potential issues.

Characteristic	Description
Shift Feel	Positive engagement with moderate effort
Clutch Engagement	Smooth take-up with progressive engagement
Gear Noise	Minimal gear whine in lower gears is normal
Cold Weather Operation	Slightly stiffer shifting until fluid warms
Reverse Gear Engagement	May require slight vehicle movement for smooth engagement
Shift Lever Vibration	Minimal vibration at certain RPM ranges is normal

Performance Driving Tips

Optimize your driving experience with these performance-oriented techniques.

Rev-Matching: Blip throttle to match engine speed during downshifts.
Heel-Toe Technique: Brake with toe while blipping throttle with heel for downshifts.
Quick Shifts: Practice smooth but rapid shifts without forcing the lever.
Launch Control: Hold RPM at 3000-3500 for optimal starts (track use only).
Engine Braking: Use lower gears for controlled deceleration on steep grades.

CAUTION! Aggressive shifting and clutch dumping can cause premature component failure.

Troubleshooting Guide

Common issues and solutions for the 2013 Acura ILX manual transmission.

Symptom	Possible Cause	Corrective Action
Difficulty shifting into gear	Low fluid, worn synchronizers, clutch not disengaging	Check fluid level, inspect clutch hydraulic system, adjust clutch pedal
Grinding during shifts	Worn synchronizers, incorrect fluid, linkage issues	Change transmission fluid, inspect shift linkage, check synchronizers
Clutch slippage	Worn clutch disc, contaminated disc, weak pressure plate	Inspect clutch assembly, check for fluid leaks, replace clutch components
Vibration in shift lever	Worn engine/transmission mounts, unbalanced components	Inspect mounts, check driveshaft balance, verify proper installation
Noise in neutral	Worn input shaft bearing, pilot bearing failure	Inspect bearings, check transmission input shaft, replace as needed
Hard shifting when cold	Incorrect fluid viscosity, synchronizer issues	Use proper MTF, allow transmission to warm up, inspect synchronizers
