2002 Acura TL Type S Manual Transmission Swap

The 2002 Acura TL Type S manual transmission swap involves converting the automatic transmission to a manual gearbox for improved performance and driving engagement. This comprehensive guide covers parts sourcing, installation procedures, compatibility considerations, and post-swap tuning. The swap typically uses components from compatible Honda/Acura models and requires mechanical expertise, specialized tools, and careful attention to detail.

Prerequisites and Parts List

Essential components needed for a complete manual transmission swap on the 2002 Acura TL Type S.

Tools Required

Specialized tools and equipment needed for the transmission swap procedure.

1. Transmission jack and engine support bar
2. Complete metric socket and wrench set (8mm-19mm)
3. Torque wrench (ft-lb and in-lb capable)
4. Hydraulic line bleeding kit
5. CV axle removal tools
6. Clutch alignment tool
7. Transmission fluid pump
8. Electrical connectors and wiring tools

WARNING! Use proper safety equipment including jack stands, gloves, and eye protection. Transmission is heavy; lift with care.

Removal Procedure

Step-by-step process for removing the automatic transmission.

1. Disconnect battery and drain transmission fluid
2. Remove air intake system and exhaust components as needed
3. Disconnect shift cable and transmission cooler lines
4. Remove drive axles and half shafts
5. Support engine with support bar
6. Remove transmission mount and bellhousing bolts
7. Carefully lower transmission using transmission jack
8. Remove torque converter and flexplate

CAUTION! Ensure vehicle is securely supported on jack stands. Transmission fluid may be hot.

Installation Steps

• Flywheel Installation: Clean mounting surface, apply thread locker, torque to specification (81 ft-lb)
• Clutch Assembly: Use alignment tool, torque pressure plate bolts in star pattern (19 ft-lb)
• Transmission Mounting: Apply grease to input shaft splines, carefully guide transmission into position
• Hydraulic System: Install clutch master and slave cylinders, bleed system thoroughly
• Shifter Installation: Install shifter assembly and adjust linkage/cables
• Electrical Connections: Install reverse light switch and neutral safety switch bypass
• Final Assembly: Install drive axles, fill with transmission fluid, reconnect battery

Compatibility Notes

Key compatibility considerations for the 2002 Acura TL Type S manual swap.

Transmission: J-series manual transmissions from 2002-2003 Acura TL Type S, CL Type S, or Honda Accord V6. ECU: Requires manual transmission ECU or reflash to eliminate automatic transmission codes. Axles: Manual transmission specific CV axles required for proper fitment. Pedals: Complete manual pedal assembly from compatible model.

Wiring and Electronics

Electrical modifications required for proper manual transmission operation.

1. Install manual transmission ECU or have automatic ECU reflashed
2. Wire clutch pedal position switch for starter safety interlock
3. Connect reverse light switch to existing harness
4. Bypass or disable automatic transmission range sensor
5. Reprogram or replace instrument cluster if needed

Tip: Label all electrical connectors during disassembly for easier reassembly.

Clutch System Setup

Proper installation and bleeding of the hydraulic clutch system.

1. Bench bleed clutch master cylinder before installation
2. Install master cylinder and connect to pedal assembly
3. Route hydraulic line to slave cylinder avoiding sharp bends
4. Bleed system starting at slave cylinder until air-free
5. Adjust clutch pedal free play (10-15mm typical)
6. Test clutch engagement and disengagement
7. Check for leaks at all connections

WARNING! Do not reuse old hydraulic components. Use new fluid and inspect all lines.

Transmission Fluid Specifications

Recommended fluids and capacities for the manual transmission.

Post-Installation Testing

Comprehensive testing procedure after swap completion.

1. Check all fluid levels and inspect for leaks
2. Test clutch pedal operation and engagement point
3. Verify all gears engage smoothly without grinding
4. Test reverse lights and starter interlock function
5. Road test for proper shifting at various speeds
6. Check for vibrations or unusual noises
7. Monitor transmission temperature during initial drive

CAUTION! Perform initial testing in safe, controlled environment. Check all fasteners after first drive.

Common Issues and Solutions

Performance Considerations

Performance impacts and benefits of the manual transmission swap.

• Weight Reduction: Manual transmission typically 50-75 lbs lighter than automatic
• Improved Acceleration: Better power transfer and reduced drivetrain loss
• Engine Braking: Enhanced control through gear selection
• Customization: Ability to install performance clutches and lightweight flywheels
• Driver Engagement: More connected driving experience with full control
• Resale Value: Manual transmission models often command premium prices

Note: Professional installation recommended for those without advanced mechanical experience.
