Second Hand Nissan Navara Gearbox Mount

The Navara D40 ran from 2005 to 2015, and gearbox mount fitment within that generation is primarily driven by engine code and gearbox type rather than year alone — the 2.5 dCi (YD25DDTi) is the dominant engine and mounts from across the D40 range often share the same specification, but there were running production changes that could affect mounting hardware. Always confirm with the breaker by giving them your exact registration or engine code, as they can check whether the donor vehicle matches your spec.

The D40 (2005–2015) and the NP300 D23 (2016 onwards) are different generations with a substantially revised powertrain and subframe layout, so a gearbox mount from a D40 is very unlikely to be a direct swap for a D23. The D23 uses a different engine and transmission arrangement, meaning the mounting geometry and brackets will differ. Confirm with the breaker against your registration before purchasing anything across this generational boundary.

Trim level does not affect gearbox mount fitment on the Navara — the mount is determined by the engine code and gearbox type, not by whether the vehicle is an Acenta, SE, Tekna, or any other trim designation. What matters is whether the donor vehicle shares the same engine code and transmission type as yours, so focus on those details rather than the trim name. Do be aware that a used part sourced from a different trim may look slightly different cosmetically in terms of any brackets or heat shielding, so confirm the part number with the breaker if you want to be certain.

Gearbox type is a key fitment factor for a gearbox mount, and a manual transmission mount is not necessarily interchangeable with one from an automatic Navara because the gearbox casing dimensions and mounting points can differ between the two. Always tell the breaker whether your vehicle has a manual or automatic gearbox, as well as your engine code, so they can source the correct unit. Never assume a mount will cross between transmission types without confirmation.

The most important detail is your engine code, which you can find on your V5C logbook or via a VIN check — for most UK Navaras this will be the 2.5 dCi YD25DDTi, but confirming the exact code rules out any variant differences. You should also tell the breaker your gearbox type (manual or automatic) and the year of your vehicle so they can match it to the correct generation (D40 2005–2015 or D23 NP300 2016 onwards). Your registration plate will allow the breaker to cross-reference all of this and give you the most accurate match.

On the Navara, the gearbox mount (sometimes called a transmission mount or gearbox rubber) is the rubber-and-metal isolator that sits between the gearbox and the crossmember or subframe, whereas the crossmember itself is the steel beam that spans the chassis rails. These are two separate components, and breakers will list them differently, so it is worth clarifying which one you need before requesting quotes. If you are unsure, describe the symptom or the part you physically have in front of you to the breaker, and they can help identify the correct item.
