Nissan Leaf Gearbox Replacement Parts

The Nissan Leaf uses a single-speed reduction gear rather than a conventional multi-speed gearbox — there is no clutch and no gear changes, just a fixed-ratio drive unit that connects the electric motor to the front wheels. When breakers list a 'Leaf gearbox' or 'reduction gear', they mean this combined drive unit. It is a legitimate part that does wear and can be replaced, but it is worth clarifying with the breaker exactly which assembly they are supplying.

The first-generation Leaf ran from 2011 to 2017 and the second generation (ZE1 platform) arrived for 2018, bringing a substantially redesigned drivetrain and a larger 40 kWh or 62 kWh battery option — the drive units are not the same. Crossing that 2017–2018 generational boundary is a significant compatibility risk, so you should confirm against your registration with the breaker before ordering. Never assume a first-gen unit will drop straight in.

No, trim level does not affect gearbox fitment on the Leaf — Visia, Acenta, Tekna, and the e+ variants are cosmetic and equipment tiers, not mechanical ones. What actually matters is your generation (first-gen 2011–2017 or second-gen 2018+) and, within the second generation, whether your car has the 40 kWh or 62 kWh (e+) motor, as the higher-power e+ uses a different drive unit. Always quote your registration or VIN to the breaker so they can match the correct motor and reduction gear assembly.

Both 2013 and 2016 sit within the first-generation Leaf (2011–2017), so there is a reasonable basis for compatibility — the core 80 kW electric motor and single-speed drive unit ran throughout that generation. However, there were running production changes during this period, so you should confirm the part against your specific registration with the breaker rather than relying on year alone. A good breaker will cross-reference both the donor and recipient vehicles before agreeing a sale.

Both sit within the second-generation Leaf (2018 onwards), which gives a starting point for compatibility, but Nissan made ancillary and mounting changes during the second-gen production run that could affect fitment — whether a specific 2018–2019 unit crosses into a 2022 car cleanly is something you must confirm with the breaker against your registration. ECU pairing and any immobiliser coding implications are also something to raise directly with the breaker, as these are not straightforward to state as fact for every vehicle. Do not purchase without that confirmation.

The Leaf's drive unit communicates with the car's battery management and vehicle control systems, and pairing or coding requirements can vary — this is not something that can be stated as a blanket rule for every vehicle. You should raise the question of ECU compatibility and any immobiliser considerations directly with the breaker against your specific registration before buying. A reputable breaker will either advise you or point you to a specialist who can.
