The gearbox of the Nissan Navara defines how this pick-up behaves, whether in town or on country tracks. Its reliability depends heavily on the condition of its transmission — one of the key components to keep a close eye on, as it transfers power from the engine to the wheels and enables the vehicle to move forwards, reverse and stop.
This article covers the symptoms of a worn gearbox on the Nissan Navara, the different generations and their transmissions, and the options available, from routine maintenance to replacement on an exchange basis.
Spotting a Gearbox Problem on the Nissan Navara
On a pick-up, even the slightest transmission fault makes itself felt while driving. The symptoms vary, however, depending on the cause of the fault.
Warning Signs to Watch For
Crunching when changing gear, combined with difficulty selecting ratios, often points to worn synchromesh rings. A persistent, low-pitched droning noise is more likely to indicate worn bearings — leaving the repair too long risks writing off the gearbox entirely. Gears that refuse to engage may be down to insufficient or heavily contaminated gearbox oil that can no longer lubricate properly, but could also indicate a problem with the linkage or gear selector. On an automatic gearbox, a warning light may signal a faulty sensor. A constant burning smell, noise in neutral, or gears jumping out complete the list of warning signs.
Any of these signals should prompt you to have the Navara's gearbox inspected. More broadly, any behaviour that gives you cause for concern warrants a diagnostic, even if the symptom is not among those listed above.
Identifying the Reference Before Removal
The Navara pick-up has gone through several generations since 1986, each with different transmissions. Accurate identification is essential for a successful replacement.
Generations and Their Gearboxes
The first generation, the D21, was produced until 1997 in 4x2 and 4x4 form, with petrol or diesel engines, and fitted predominantly with manual gearboxes. The second generation, the D22 (1997–2005), offered manual gearboxes — typically 5-speed — as well as automatic versions. The D40 (2005–2016) marked a significant step forward with a 7-speed manual gearbox paired with a V6 engine. From 2016, the D23, also known as the NP300, adopted a 2.5 l engine: the single-turbo 160 hp version received an improved 6-speed manual gearbox with a shorter, smoother gear lever, while the twin-turbo 190 hp versions offered a choice between a 6- or 7-speed manual and a 7-speed automatic.
Buying a gearbox for a Navara therefore requires the exact reference of the unit being replaced — getting it wrong risks incompatibility and a wasted investment. Your V5C logbook and the gearbox code are your best guides. Browse the options in our gearbox collection or the Nissan collection.
Removal, Replacement and Maintenance
Replacement is not always necessary: in some cases, an oil change — on a manual or automatic gearbox — is enough to restore it to working order. Only a diagnostic, ideally carried out by a specialist, can determine the right course of action.
A Job That Demands Precision
Repairing a gearbox depends entirely on the unit in question and requires in-depth mechanical knowledge. Removal and refitting follow precise steps: identify the gearbox type, disassemble without losing any fixings, and refit with the same care. The specialist then checks the behaviour of the exchange or used gearbox, verifies the seals to prevent any oil leaks, and fills it with a lubricant suited to the pick-up. On an automatic gearbox, sensor adjustment demands a high degree of precision. Regular maintenance — in particular, oil changes at the recommended intervals — maximises the service life of the transmission. To understand how it all works, see our guide how a gearbox works.

Frequently Asked Questions
Should I be worried about a constant droning noise on my Navara?
This noise often points to worn bearings. It is advisable to have the gearbox diagnosed promptly to prevent it from failing completely.
Will a D22 gearbox fit a D40?
No. Each generation has its own architecture and number of ratios. The reference must match your version exactly.
Can delivery be made directly to my garage?
Yes. As gearboxes are heavy, it is often more practical to have it delivered directly to the mechanic carrying out the replacement.
