Used Mercedes-Benz CLE Gearbox

The CLE (C236 coupe, A236 cabriolet) launched for the 2023 model year as an all-new generation replacing the C-Class and E-Class coupes, so cars built across 2023 and 2024 sit within the same generation with no facelift boundary yet established. Fitment is driven primarily by engine code rather than model year alone, so you should match the engine code from your V5 or a VIN check against the donor car. Confirm exact compatibility with the breaker against your registration before purchasing.

These are different engines — the 220d uses a four-cylinder diesel engine code while the 300 uses a four-cylinder petrol engine code — and the gearboxes are not interchangeable between fuel types. Although both models use a nine-speed automatic transmission in the CLE range, the specific gearbox unit is matched to the engine family. Always supply your full engine code (found on your V5C or via a VIN check) to the breaker so they can source the correct unit.

Trim level does not affect gearbox fitment on the CLE; what matters is the engine code, fuel type, and whether the car is a standard or AMG-badged variant with a different powertrain. AMG Line is a styling pack and does not alter the drivetrain, so a gearbox from a CLE AMG Line and a standard CLE with the same engine code should be the same unit. Be aware that trim differences may mean ancillary brackets or wiring looms look slightly different cosmetically, so confirm the exact part against your registration with the breaker.

The CLE replaced the C-Class Coupe (C205) and E-Class Coupe (C238) from 2023 onwards and is built on a distinct platform, so gearboxes from those older models are not a straightforward swap. Engine codes and transmission software differ between generations, even where engine families appear similar on paper. Supply your CLE's engine code to the breaker and ask them to confirm directly whether any cross-generation fitment is possible for your specific registration.

The CLE 450 uses a straight-six petrol engine with 4MATIC all-wheel drive, while the CLE 300 uses a four-cylinder petrol engine, and these are entirely different gearbox units — not interchangeable. Engine code is the single most important detail here, and the transfer case arrangement on the 4MATIC model adds further complexity. Give the breaker your engine code and confirm whether your car is two-wheel or all-wheel drive before they source a unit.

Mercedes-Benz transmissions can involve electronic communication with the vehicle's ECU and may require coding or adaptation after fitting, which is something to discuss with the garage carrying out the work. This is not something Findapart or a breaker can guarantee in advance, as pairing requirements can vary by build date and specification within the same model. Confirm with both the breaker and your fitting garage what coding work may be needed for your specific registration before committing to a purchase.
