The story of this transmission
Mercedes-AMG's 45 models are the hot hatches and compact performance cars of the three-pointed star. The current generation, launched in 2019, uses the M139 2.0-litre turbo four-cylinder, hand-built by AMG and rated at 285 kW in standard form and 310 kW as the S. It went into the A 45 hatch, the CLA 45 and later the GLA 45, all with 4MATIC all-wheel drive. This is a used eight-speed gearbox listed for that all-wheel-drive 2.0 AMG application.
These cars have a strong following in South Africa among enthusiasts and track-day regulars, and many are driven hard. That matters when buying a used gearbox: launch control, repeated hard starts and aggressive tuning all add load. Before fitment, check the condition of the transfer unit and rear drive, scan for stored transmission faults, and use the correct Mercedes-approved fluid.
The earlier A 45 (2013 to 2018) used a different engine and gearbox, so a VIN check is essential. We match the code on your old unit to this one before dispatch.
Because performance cars are often modified and driven at the limit, this unit carries a start-up warranty only. Specialist workshops like having a tested used gearbox available, as a replacement from the dealer is expensive and lead times can be long.

FAQs
Will this fit the older A 45 AMG?
The 2013 to 2018 A 45 used a different engine and gearbox. This listing is the 8-speed unit for the all-wheel-drive 2.0 AMG. Send your VIN so we can confirm.
Why only a start-up warranty?
High-performance gearboxes are often used with launch control, tuning and track driving, so we offer a start-up warranty only. Fitment by an RMI-registered workshop with fresh fluid is still required.
Will it need coding?
Expect the workshop to run adaptations and possibly coding with Mercedes diagnostic equipment after fitting.
Do you deliver outside South Africa?
Yes, to Botswana, Namibia, Zimbabwe, Zambia, Mozambique, Lesotho, Eswatini and Malawi.
