Mercedes-Benz CLA automatic gearbox repair for dual-clutch coupes
The CLA brings coupe styling to a compact platform, and a dual-clutch gearbox that reacts to how you drive.
The C117 CLA from 2013 used the 7G-DCT wet-clutch dual-clutch, and the C118 from 2019 uses the 8G-DCT. Performance CLA 45 AMG cars add more torque.
Typical complaints are hesitation, jerky low-speed driving, clunks, fault messages, limp mode and mechatronic faults.
We repair and rebuild CLA 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 CLA has.

Understanding the CLA dual-clutch
Two clutches and a mechatronic brain.
Wet clutches
The 7G-DCT and 8G-DCT use oil-cooled clutches. They handle torque well but depend on clean fluid.
Missed services shorten life.
- Judder
- Hesitation
- Slip
Control and software
The mechatronic unit and software decide shift points. Faults cause jerks and limp mode.
Software updates and repairs both matter.
- Jerks
- Missed gears
- Fault messages
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 CLA should still be driven.
