JDM to USDM Installation & Technical Guide

To ensure 100% OBDII compliance and a “plug-and-play” experience, professional Toyota technicians recommend these steps:

• Solenoid & Internal Harness Transfer: You must transfer your original USDM Transmission Wiring Harness and Solenoids from your old transmission to the JDM unit. JDM electrical plugs can vary in shape or pin count; using your original electronics ensures the ECU communicates perfectly and prevents “Check Engine” lights (MIL).

• Front Bellhousing: Must swap over your front USDM Bellhousing as the JDM Casing has a different bolt line up variation.

• Neutral Safety Switch: Transfer your original USDM Neutral Safety Switch (Range Sensor) to ensure your gear indicator and starting circuit function exactly as they did before.

• Oil Cooler Flush: It is mandatory to flush your transmission cooler lines and radiator. Debris from a failed transmission can hide in the lines and will destroy your “new” JDM unit if not properly cleared out.

• Fluid Requirements: Use only high-quality Toyota ATF World Standard (WS) fluid. Do not use older T-IV or generic multi-vehicle fluids, as the U341E is specifically designed for the lower-viscosity WS fluid.

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.
