Essential Installation Notes

• Fluid System Notice: The A340H utilizes a shared hydraulic fluid system between the transmission assembly and the transfer case. Standard drain-and-fill procedures require checking both separate fluid reservoirs to ensure proper operating levels.

• Wiring Requirements: For JDM-sourced replacements or conversions, ensure matching plugs for the Electronically Controlled Transmission (ECT) solenoids and speed sensors, as differences exist between early (1988–1991) and late (1992–1995) model years.

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.
