Operation Guidelines

Proper shifting techniques for optimal performance and longevity.

Clutch Operation: Depress clutch pedal fully before shifting gears.
Smooth Shifting: Apply gentle pressure when moving shift lever between gears.
Rev Matching: Match engine RPM to transmission speed when downshifting.
Avoid Riding Clutch: Do not rest foot on clutch pedal while driving.
Proper Start Procedure: Use first gear for initial acceleration from stop.

WARNING! Do not force shift lever if resistance is felt. Return to neutral and retry.

Maintenance Schedule

Regular maintenance ensures optimal transmission performance and longevity.

Fluid Inspection: Check transmission fluid level every 7,500 miles.
Fluid Change: Replace transmission fluid every 30,000 miles or 2 years.
Clutch Adjustment: Check clutch pedal free play every 15,000 miles.
Linkage Inspection: Inspect shift linkage and cables every 15,000 miles.
Seal Inspection: Check for fluid leaks at seals and gaskets during oil changes.

CAUTION! Use only recommended fluids to prevent transmission damage.

Shifting Mechanism

The shift mechanism consists of shift lever, cables, and linkage assembly.

Shift Lever: Direct cable-operated mechanism with rubber isolators.

Shift Pattern: Reverse (left and up), 1st (left and down), 2nd (straight down from 1st), 3rd (straight up from 2nd), 4th (straight down from 3rd), 5th (straight up from 4th). Shift Linkage: Steel cables connecting shift lever to transmission selector mechanism. Bushings: Rubber and plastic bushings at connection points requiring periodic inspection.

Clutch System

Hydraulic clutch system with master cylinder, slave cylinder, and release bearing.

Clutch Pedal: Depress fully to disengage clutch for gear changes.
Master Cylinder: Mounted on firewall, converts pedal pressure to hydraulic pressure.
Slave Cylinder: Mounted on transmission, actuates clutch release fork.
Release Bearing: Engages pressure plate fingers to disengage clutch.
Clutch Disc: Splined to transmission input shaft, between flywheel and pressure plate.

Tip: Clutch pedal should have 0.4-0.8 inches (10-20mm) of free play.

Common Issues

Typical problems encountered with 1993 Integra manual transmission.

Grinding Gears: Worn synchronizers or low fluid level.
Difficulty Shifting: Damaged shift cables or worn linkage bushings.
Clutch Slippage: Worn clutch disc or contaminated friction surface.
Fluid Leaks: Worn seals at axle outputs or selector shaft.
Noise in Neutral: Worn input shaft bearing or pilot bearing.
Vibration: Worn engine/transmission mounts or unbalanced components.
Stuck in Gear: Bent shift forks or internal transmission damage.
Hard Clutch Pedal: Damaged pressure plate or hydraulic system issues.

WARNING! Address transmission issues promptly to prevent further damage.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Grinding when shifting	Low fluid, worn synchros	Check fluid level; replace synchronizers if needed.
Hard to shift into gear	Clutch not disengaging	Check clutch hydraulic system; adjust pedal free play.
Transmission jumps out of gear	Worn detents or shift forks	Inspect internal shift mechanism; replace worn components.
Whining noise in all gears	Worn bearings	Replace input shaft or output shaft bearings.
Fluid leakage	Worn seals or gaskets	Replace axle seals, selector shaft seal, or case gaskets.
Vibration during acceleration	Worn mounts or CV joints	Inspect engine/transmission mounts and CV joints.

Service Procedures

Basic service procedures for maintenance and repair.

Fluid Drain and Refill: Remove fill plug first, then drain plug. Refill until fluid runs out fill hole.
Clutch Replacement: Remove transmission, replace clutch disc, pressure plate, and release bearing.
Shift Cable Adjustment: Loosen lock nuts, set neutral position, tighten lock nuts.
Seal Replacement: Clean area, remove old seal, install new seal with proper driver.
Bearing Replacement: Requires transmission disassembly and special tools.

CAUTION! Transmission service requires proper tools and technical knowledge.
