Installation Process

Compatibility Notes

Critical compatibility information for successful conversion.

Model Years: 2004-2008 Acura TSX with K24A2 engine. Transmission: 6-speed manual from same generation TSX. ECU: Must match manual transmission configuration. Axles: Manual transmission specific CV axles required. Mounts: Engine and transmission mounts differ from automatic.

Wiring and Electronics

Electrical system modifications for manual conversion.

  1. Replace automatic ECU with manual transmission ECU
  2. Modify transmission harness for manual operation
  3. Install reverse light switch wiring
  4. Connect clutch pedal position sensor
  5. Program ECU if required for vehicle operation
  6. Disable automatic transmission error codes

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

Clutch System Installation

Proper clutch installation ensures smooth operation and longevity.

  1. Install flywheel with proper torque sequence
  2. Align clutch disc using alignment tool
  3. Torque pressure plate bolts in star pattern
  4. Install release bearing and clutch fork
  5. Connect slave cylinder and bleed system
  6. Adjust clutch pedal free play
  7. Test clutch engagement and disengagement

WARNING! Do not contaminate clutch surfaces with oil or grease during installation.

Transmission Mounting

Secure transmission installation for proper alignment and vibration control.

Install transmission with proper support. Align engine and transmission angles. Torque mount bolts to factory specifications. Check clearance with subframe and exhaust components. Ensure shift linkage moves freely without binding.

Final Setup and Testing

Complete system verification and operational testing.

  1. Fill transmission with proper fluid type and quantity
  2. Check all fluid levels and connections
  3. Test clutch operation and pedal feel
  4. Verify gear engagement in all positions
  5. Test reverse lights and safety switches
