Tip: Label all connectors and take photos during disassembly for reference.

Installation Steps

Manual transmission installation procedure.

  1. Install manual transmission flywheel with new bolts (torque to spec)
  2. Install clutch disc and pressure plate using alignment tool
  3. Mount manual transmission to engine block
  4. Install transmission mount and crossmember
  5. Install clutch hydraulic system (master and slave cylinders)
  6. Install manual pedal assembly and shifter mechanism
  7. Connect shift cables and clutch hydraulic lines
  8. Install drive shafts and axles
  9. Fill transmission with appropriate manual transmission fluid
  10. Bleed clutch hydraulic system

WARNING! Torque all bolts to factory specifications and use thread locker where specified.

Wiring and Electronics

Electrical modifications required for manual conversion.

ECU/ECM: Replace automatic ECU with manual version or reflash existing ECU. Neutral Safety Switch: Bypass or modify automatic transmission safety circuits. Reverse Lights: Connect manual transmission reverse switch to existing wiring. Speed Sensor: Ensure manual transmission speed sensor compatibility with vehicle speedometer. Check Engine Light: Address any transmission-related error codes.

Clutch System Setup

Clutch hydraulic system installation and bleeding procedure.

  1. Mount clutch master cylinder to firewall
  2. Install clutch pedal and connect to master cylinder
  3. Mount slave cylinder to transmission bellhousing
  4. Connect hydraulic line between master and slave cylinders
  5. Bleed system using pressure bleeder or manual method
  6. Adjust clutch pedal free play and engagement point
  7. Test clutch operation before starting engine

CAUTION! Proper clutch system bleeding is critical for safe operation.

Testing and Calibration

Post-installation testing and system calibration.

  1. Check transmission fluid level
  2. Test clutch engagement and shifting without engine running
  3. Start engine and check for unusual noises
  4. Test shifting through all gears while stationary
  5. Road test for proper shifting under load
  6. Check for fluid leaks and unusual vibrations
  7. Calibrate speedometer if necessary
  8. Verify reverse lights and cruise control operation

Common Issues

IssueDescriptionPrevention/Solution
Hard ShiftingDifficulty engaging gearsCheck clutch adjustment, fluid type, synchro condition
Clutch SlippageRPM increases without accelerationVerify clutch installation, hydraulic system function
Gear GrindingNoise when shiftingCheck synchros, transmission fluid, shift linkage
Fluid LeaksTransmission or hydraulic fluid leakageInspect seals, gaskets, line connections
Check Engine LightTransmission-related codesAddress ECU programming, sensor connections

Troubleshooting
