Honda Prelude 5 Speed Manual Non LSD Transmission JDM H22A M2V5

About this unit

Vehicle Fitment

This transmission serves as a direct replacement or performance upgrade for the following North American models:

• Honda Prelude VTEC: 1993, 1994, 1995, 1996 (Direct Replacement)

• Honda Prelude Si (H23A1): 1992–1996 (Significant Gearing Upgrade)

• Honda Accord: 1990–2002 (Popular H-Series Swap Transmission)

• Compatibility Note: As a Non-LSD unit, this uses standard 36mm axles. If you are swapping this into a vehicle that previously had an LSD transmission (like the M2B4), you will need to ensure your axle inner-stubs match the open differential splines.

JDM to USDM Installation & Technical Guide

To ensure a seamless installation and long-term durability, professional technicians recommend the following steps:

1. Vehicle Speed Sensor (VSS): Transfer your original USDM VSS if your speedometer calibration differs. The JDM unit is physically compatible, but using your original sensor ensures 100% accuracy with your factory cluster.

2. Clutch & Flywheel: While the transmission is out, we strongly recommend installing a new clutch disc, pressure plate, and throw-out bearing. Use a lightweight flywheel to further enhance the H22A’s rev-happy nature.

3. Transmission Fluid: Use only Genuine Honda Manual Transmission Fluid (MTF). These older Honda synchros are sensitive to sulfur additives found in many generic gear oils, which can lead to premature “notchy” shifting.

4. Shifter Cables: Ensure your shifter cables and bushings are in good condition. Upgrading to solid shifter bushings during this install will drastically improve the “mechanical feel” of the M2V5.

5. Axle Seals: While the unit is on the bench, we recommend installing new OEM axle seals to prevent leaks and protect your fresh MTF.

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.
