Vehicle Fitment
This transmission serves as a direct replacement for the following North American models:
Honda Civic Sedan (DX, LX, EX): 2006, 2007, 2008, 2009, 2010, 2011
Honda Civic Coupe (DX, LX, EX): 2006, 2007, 2008, 2009, 2010, 2011
Compatibility Note: Specifically for the 1.8L R18A. It will not fit the 2.0L Civic Si (K20Z3) or the Civic Hybrid models, as the bellhousing and gear ratios are entirely different.
JDM to USDM Installation & Technical Guide
To ensure a perfect install and long-term reliability, professional Honda technicians recommend these steps:
Shifter & Linkage: This JDM unit is a direct bolt-in for your existing linkage. However, we recommend inspecting your shifter cable bushings during the swap. Replacing worn bushings with solid or high-quality rubber units will maximize the “crisp” feel of your JDM transmission.
Clutch & Flywheel: Since the transmission is removed, always install a new clutch disc, pressure plate, and throw-out bearing. Don’t forget to replace the pilot bearing if applicable and resurface or replace your flywheel to prevent clutch chatter.
VSS (Vehicle Speed Sensor): Transfer your original USDM Speed Sensor and Reverse Light Switch to the JDM unit. This ensures your speedometer remains 100% accurate and your reverse lights function without wiring modifications.
Fluid Requirements: Use ONLY Honda Genuine Manual Transmission Fluid (MTF). Honda transmissions are notoriously picky; using standard 75W-90 gear oil will lead to stiff shifting and accelerated synchronizer wear.
What is included
You receive exactly what is pictured. Engines are supplied as a long block assembly with the components visible in the photos. Accessories such as the alternator, starter, intake manifold or sensors are included only where you can see them on the unit, so check the photographs before ordering and ask us if anything is unclear.
Before you order
- Confirm the engine code against your own vehicle, not just the model year.
- Japanese market units can differ from the US version in intake, loom and sensors.
- Replace the timing components, water pump and seals while the unit is out. It is cheap insurance on an engine this age.
- Keep your original accessories until the swap is finished and running.
