Cheap Nissan Primastar Gearbox

The Nissan Primastar was sold in the UK as a single generation running from 2002 to 2016, sharing its platform and drivetrain family with the Vauxhall Vivaro and Renault Trafic of the same era, so there is no named generation boundary to cross within the Primastar itself. Fitment within that range depends heavily on the engine code, which you will find on your V5C or via a VIN check, because mechanical changes followed engine revisions rather than calendar years. Give your engine code to the breaker and they can confirm whether a unit from a different year will bolt up correctly.

No — the 1.9 dCi and 2.0 dCi are different engines with different engine codes, and the gearboxes matched to them are not the same unit, so they are not a straightforward swap. Engine code is the single most important detail for gearbox fitment on the Primastar; always match the replacement to your exact code rather than going by engine size alone. Confirm the specific codes with the breaker against your registration before purchasing.

Trim level does not affect gearbox fitment on the Primastar — the gearbox is determined by the engine code and whether the van is manual or automatic, not by whether it is badged Comfort, Sport, or any other trim. You may find cosmetic differences between donor and recipient vehicles such as interior finish or badge details, but these are irrelevant to the mechanical fit. Focus on matching the engine code and gearbox type when speaking to the breaker.

Both 2006 and 2012 fall within the same single Primastar generation (2002–2016), so there is no named generation boundary between them, which is a good starting point. However, engine specification and ancillary details can vary across that production span, so a year gap of that size means you should not assume direct compatibility without checking the engine codes on both vehicles. Share both registration numbers or engine codes with the breaker so they can verify the match before you commit.

Manual and automatic gearboxes are entirely different units and are not interchangeable — swapping between the two would require significant additional work beyond fitting the box itself and is not a like-for-like used-parts job. When searching for a replacement, always specify manual or automatic to match what is already in your vehicle. The breaker will need your engine code and gearbox type to source the correct unit.

The Nissan Primastar, Vauxhall Vivaro (2001–2014 generation), and Renault Trafic (2001–2014 generation) are platform-sharing vehicles with closely related drivetrains, and breakers often cross-reference between them. Whether a specific unit from one of those vehicles fits yours depends on the engine code and exact specification matching up, not just the shared platform. Route this question to the breaker with your engine code and they can tell you whether a Vivaro or Trafic donor unit is a confirmed match for your registration.
