Installation notes

Yes — the hydraulic-clutch D-series 5-speed manual gearbox from a 1996–2000 Civic (EK) fits a 1996–2000 automatic Civic (EK) with the manual pedals, clutch hydraulics, flywheel and clutch, shift linkage, manual starter, manual gearbox brackets and a manual ECU. An Australian owner documented the conversion on an EK coupe (EJ8) with the engine left in the car, using an engine crane to support it while the mounts were off, and reported roughly 8 hours of work. His parts list: gearbox, manual starter and bolts (one or both are longer than the automatic ones), shift linkage, flywheel and clutch, brake pedal, clutch pedal and bracket, clutch master and slave cylinders with hard and flex lines, optional firewall clutch line brackets, the gearbox-to-engine alloy bracket, flywheel cover plate, manual ECU, optional manual cluster, brake fluid for the clutch and two litres of Honda manual transmission fluid. For mounts he needed the manual upper gearbox bracket (with a new bolt for its extra hole) and the manual front gearbox bracket with three longer bolts. A US FAQ on the same conversion lists the same core parts, adds a manual VSS and notes that the automatic driveshafts are retained, and estimates about 8–10 hours, saying the job is much easier with the engine out.

Required modifications

The automatic pedal box is replaced with the manual pedal assembly (or a manual clutch pedal, bracket and pin are added), and the clutch master cylinder, hard line, flex line and slave cylinder are fitted. The torque converter is replaced with a manual flywheel, clutch and pilot bearing. The automatic shifter is replaced with D-series manual shift linkage, and the opening left by the auto shifter is covered with a fabricated plate. The park/neutral (starter interlock) and reverse-light wiring must be adapted to the manual gearbox's switches, and the key interlock on the steering column is removed. The ECU must be changed to a manual-transmission unit or reprogrammed, otherwise it will set codes for the missing automatic transmission solenoids.

Caution

Important caveats

  • The sources disagree on the rear gearbox mount: the OzHonda writeup says the automatic and manual rear mounts are the same, while the Honda-Tech FAQ says they are different and lists a manual rear mount (50810-SR3-030). Compare your parts before buying.
  • D16 flywheels differ: the OzHonda author found a clutch kit for a D16Y8 flywheel did not fit a D16Y4 flywheel because the pressure plate bolt and dowel spacing differ. Buy the clutch to suit the flywheel you actually fit.
  • OBD2 automatic ECUs cannot simply be used: the author's EJ8 used a P2P ECU that he could not convert, so a manual ECU was needed. Another member reported converting an EK1 P2K automatic ECU to manual, but no method is documented in the source.
  • Speed sensor and reverse light switch are often missing from used gearboxes; check the gearbox is complete before you start.
  • The Honda-Tech FAQ describes removing the pedal assembly as the hardest part of the job.
  • If the car is registered in Australia, check whether your state requires the conversion to be declared or engineered.
