JDM to USDM Installation & Technical Guide

To ensure 100% OBDII compliance and a smooth swap, professional technicians recommend these “External Swap” steps:

• Solenoid & Internal Harness Transfer: You must transfer your original USDM internal wire harness and solenoids to the JDM unit. JDM electrical plugs are frequently different; using your original USDM electronics ensures the ECU receives the correct resistance values and prevents “Check Engine” lights.

• Speed Sensor (VSS): Reuse your original USDM Speed Sensor. This ensures your speedometer remains 100% accurate and prevents any cruise control issues.

• Transfer Case & Flanges: This unit typically includes the JDM transfer case. Ensure the front and rear output flanges match your USDM driveshafts. If they differ, it is often easiest to bolt your original USDM transfer case onto the JDM transmission housing.

• Neutral Safety Switch: Transfer your original USDM Neutral Safety Switch (Range Sensor) to ensure your gear indicator and starting circuit function correctly.

• Fluid Service: Flush your transmission cooler lines thoroughly. Fill only with high-quality Dexron III compatible ATF. Pro Tip: Check your radiator for corrosion—replacing it now is the best way to prevent the “Pink Milkshake” coolant-fluid mix that destroys these gearboxes.

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.
