What is a gearbox code?
A gearbox code is the manufacturer reference identifying one exact transmission variant. As with engines, a single vehicle can be built with several different gearboxes depending on engine, drivetrain and trim level, so the code rather than the model year is what actually confirms fitment.
- Confirms fitment where model and year cannot
- Depends on engine, drivetrain and trim
- Automatics and dual-clutch units sit above manuals in price
- Buying the matched engine removes pairing risk
- Send your registration if you cannot find the code
A gearbox code identifies the exact transmission variant. As with engines, one model can take several different gearboxes depending on engine, drivetrain and trim level, so the code — not the model year — is what confirms fitment.
Matching a gearbox to an engine
Buying a gearbox and engine from the same donor vehicle removes pairing risk entirely, because the two are known to have worked together. Sourcing them from different donors is possible but adds a compatibility question.
What affects the price
The unit itself, its mileage, whether it is plain used or reconditioned, and how scarce the code is. Automatics and dual-clutch units sit above manuals.
Why this matters when you are buying
Terms like this one get used loosely in listings, and the difference between two of them is often the difference between a part that fits and one that does not. If a seller is vague about which they mean, ask — a straight answer takes a message and saves a return.
For anything mechanical or electrical, back the description up with a part number. It removes the ambiguity entirely.
