Second Hand Mercedes-Benz CLA Gearbox

The Mercedes CLA ran as a single first generation (C117) from 2013 to 2019, with a facelift in 2016, so a 2014 and a 2017 are from the same overall generation but sit either side of that facelift boundary. Whether the gearbox crosses that boundary without issue depends heavily on your engine code, which you'll find on your V5 or via a VIN check — confirm the codes match and check ancillary or mounting differences with the breaker against your registration before buying.

For a gearbox, the engine code matters far more than the year — Mercedes fitted different petrol and diesel units to the CLA that use entirely different gearboxes even within the same model year. Pull the engine code from your V5 or a VIN check and give it to the breaker; the year alone is not enough to confirm fitment.

No — petrol and diesel CLAs use different gearboxes and the two are not interchangeable, even if the cars are the same year and generation. Always confirm your fuel type and engine code with the breaker to make sure you're being quoted the correct unit.

Trim level — whether SE, Sport, or AMG Line — does not affect which gearbox is fitted; what matters is the engine code and whether the car has a manual or automatic transmission. The AMG Line badge is a cosmetic and suspension package rather than a mechanical one on standard CLA models, so a gearbox from a lower trim car with the same engine code is the part to match.

The second-generation CLA (C118) launched in 2019 as a new platform with revised engines, so the generations are not the same mechanically and gearboxes from a C117 should not be assumed to cross over to a C118. Give the breaker both the donor and recipient engine codes and registrations so they can confirm whether fitment is possible — never assume generation-to-generation compatibility.

No — the 200 is a petrol and the 220d is a diesel, and they use fundamentally different gearboxes that are not interchangeable regardless of year or generation. Always match on engine code and fuel type, and confirm with the breaker that the specific codes align before purchasing.
