Cheap Mercedes-Benz C-Class Gearbox

The current W205 C-Class ran from 2014 onwards, so both years sit within the same generation, which is a good starting point. Fitment is driven primarily by engine code rather than year alone, so you need to match the engine code from your V5 or a VIN check to the donor car's code. If the engine codes align and the gearbox type matches (automatic or manual), there is a reasonable chance of compatibility, but confirm with the breaker against your registration before purchasing as ancillary and mounting details can vary mid-production.

The W204 ran from 2007 to 2014 and the W205 from 2014 onwards, so these are separate generations with different platform architectures, and a direct swap is very unlikely. Engine codes, gearbox casings, and mounting points changed significantly between generations, so these should be treated as non-interchangeable in the vast majority of cases. Always confirm against your registration with the breaker rather than assuming any cross-generation compatibility.

Trim level on its own does not affect gearbox fitment — the SE, Sport, AMG Line, and Exclusive trims are largely cosmetic and specification distinctions rather than mechanical ones. What actually determines compatibility is the engine code, fuel type, and whether the car has an automatic or manual gearbox. One thing worth noting is that AMG Line cars may share the same drivetrain as SE or Sport variants on the same engine, so the trim badge tells you very little; pull the engine code from your V5 and match that to the donor vehicle.

The badge (C220d, C200d) reflects output tuning and does not always mean a different engine family, but you cannot assume interchangeability based on badge alone. The engine code is the critical detail — if both cars share the same engine code the gearbox is far more likely to be compatible, whereas different engine codes usually mean different bell-housing or mounting specifications. Check the engine code on your V5 or via a VIN check and give that to the breaker so they can cross-reference the donor unit accurately.

The W205 received a facelift in 2018, and while the generation spans from 2014 to 2021, mechanical changes can occur at a facelift even within the same bodyshell. Engine codes are the most reliable guide — if the donor and recipient share the same engine code and gearbox type, compatibility is plausible, but whether specific ancillary components or mounting points changed across the 2018 facelift boundary is something you should confirm with the breaker against your registration rather than assuming.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or by running a VIN check — it is far more precise than the badge or year alone. You should also confirm the fuel type (petrol or diesel) and whether your car has a manual or automatic gearbox, including the specific automatic variant if you know it (for example, 7G-Tronic). Providing your full registration number lets the breaker cross-reference everything and helps them flag any known mid-production changes that could affect ancillary parts or ECU pairing requirements.
