Second Hand Nissan Pathfinder Gearbox

The R51 Pathfinder ran from 2005 to 2013, so in principle a gearbox from another R51 should be your starting point — but the most important thing is matching the engine code exactly, since the R51 was offered with both the 2.5 dCi diesel and the 4.0 V6 petrol, and their gearboxes are not interchangeable. Confirm the engine code from your V5 or a VIN check before approaching a breaker. Mid-production ancillary and mounting changes can also affect a direct swap, so always confirm compatibility against your registration with the breaker.

The R50 (1996–2004) and the R51 (2005–2013) are entirely different generations with different engines and transmission designs, so a gearbox from an R50 will not cross that generation boundary and fit an R51. You need a gearbox sourced from within the correct generation and matched to the same engine code as your vehicle. Always confirm against your registration with the breaker before purchasing.

Trim level does not affect gearbox fitment — the gearbox is determined by the engine code and whether the vehicle has a manual or automatic transmission, not by whether it is standard, SVE, or Aventura specification. You may find cosmetic or interior differences between trim levels, but mechanically the gearbox requirement is the same across trims sharing the same engine. Give the breaker your engine code and gearbox type (manual or auto) and trim is irrelevant to the search.

Yes, it matters enormously — the manual and automatic gearboxes are completely different units and are not interchangeable even if the engine code matches. Make sure you specify both the engine code (for the R51 2.5 dCi this will be on your V5 or from a VIN check) and the gearbox type when contacting a breaker. Fitting the wrong type would require significant additional conversion work that is not a straightforward swap.

Whether a used gearbox requires ECU pairing or immobiliser coding to your specific vehicle is something you must confirm directly with your breaker and a qualified mechanic against your registration — this is not something that can be stated as a blanket rule. This is an important question to raise before you buy, as coding requirements can affect the total cost and complexity of the job. A good dismantler will be able to advise based on the specific unit they have available.

The R51 Pathfinder received a facelift during its production run, and while both your 2007 and a 2010 donor vehicle sit within the same R51 generation, mid-production changes can affect ancillary components and mountings. The engine code match is still the primary check — if the codes align and the gearbox type (manual or auto) is the same, it is a promising starting point. However, you should confirm compatibility across the facelift period directly with the breaker against your registration before committing to a purchase.
