Second Hand Vauxhall Insignia Gearbox Mount

The Insignia A ran from 2008 to 2017, with a facelift in 2013, so a 2012 car is pre-facelift and a 2015 is post-facelift — the generation boundary is important here because mounting arrangements can change across a facelift. The safest approach is to match on engine code rather than year alone, as the gearbox mount follows the drivetrain rather than the body. Give the breaker both registration numbers and let them confirm whether the codes align before buying.

The Insignia B (2017 onwards) is a substantially different car from the Insignia A (2008–2017), with a new platform, revised drivetrain mountings, and different engine configurations, so the two generations are not interchangeable for mechanical components like gearbox mounts. Always treat A and B as separate vehicles when sourcing this part. Confirm with the breaker using your exact registration and engine code to be certain.

Trim level does not affect gearbox mount fitment — SE, SRi, Elite, and Design are badge and equipment differences rather than mechanical ones. What actually determines the correct mount is your engine code and gearbox type (manual or automatic), both of which can be found on your V5C or via a VIN check. The breaker will want your engine code and registration, not your trim name.

Yes, fuel type matters because diesel and petrol variants use different engines and gearboxes, which affects the mounting configuration. Even within diesel or petrol families there are variants — for example, the 2.0 CDTi has several different engine codes depending on power output and year — so the engine code is more useful than simply saying 'diesel'. Share your full engine code with the breaker to get the right match.

Yes, automatic and manual gearboxes are physically different units and typically sit differently in the engine bay, so the gearbox mount for an automatic Insignia is unlikely to be the same as one from a manual. When contacting a breaker, confirm whether your car is a manual or automatic and supply your engine code, as this combination is what determines the correct part. Never assume a mount from a different gearbox type will fit even if the engine code matches.

The 1.8 petrol Insignia A is a fairly common engine variant, so used gearbox mounts do appear in the breaker network, but availability varies. When requesting quotes on Findapart, include your engine code (visible on your V5C or via a VIN check) alongside your registration so breakers can verify the part is from a matching drivetrain. Pricing and condition vary between dismantlers, so it is worth getting a few quotes before committing.
