Mercedes-Benz A-Class automatic gearbox repair, across CVT and dual-clutch cars
The A-Class is Mercedes-Benz's compact hatch, and its automatic changed type twice, which is why the first question is always which gearbox it has.
The W169 and early W176 A-Class used a CVT called Autotronic. From 2012 the W176 used the 7G-DCT wet-clutch dual-clutch gearbox, and the W177 from 2018 uses the 8G-DCT.
The usual complaints are hesitation, jerky low-speed driving, clunking into gear, mechatronic faults, fault messages and limp mode. A CVT fails differently from a dual-clutch, so the diagnosis starts with identification.
We repair and rebuild A-Class gearboxes with OEM-approved parts, and every repair carries a 12-month parts and labour guarantee. Call 0808 164 0418 with the registration and we will tell you which gearbox your Mercedes-Benz A-Class has.
Why use a Mercedes-Benz A-Class gearbox specialist
The A-Class is often the first Mercedes someone owns, so cost matters. A specialist diagnoses the actual fault, so you pay for the repair and not for guesswork. Call 0808 164 0418 to speak to a gearbox specialist about your Mercedes-Benz A-Class.

Understanding the A-Class CVT and dual-clutch gearboxes
Two very different automatics have been fitted over the life of the A-Class.
The Autotronic CVT
A CVT uses a steel belt between two pulleys instead of fixed gears. Wear in the belt, pulleys or control unit shows as a whine, slip or poor acceleration.
These are often repairable, depending on the wear found.
- Whine under load
- Slip or flare
- Fault messages
The 7G-DCT and 8G-DCT
A dual-clutch has two clutches and a mechatronic unit that selects gears. It is quick, but clutch wear and control faults show as jerks and hesitation.
Stop-start use wears the clutches faster.
- Jerky low-speed behaviour
- Hesitation
- Mechatronic faults
Every week on a faulty gearbox adds to the repair.
Heat and friction damage the clutches, the valve body and the fluid. Ring us and we will tell you whether your your Mercedes-Benz A-Class should still be driven.
Free phone diagnosis. 8am to 5.30pm, Monday to Friday.
