Warranty & Compliance Approved
Common Mercedes-Benz automatic gearbox problems
If your Mercedes-Benz shows any of these signs, get the gearbox checked before the fault gets worse. Driving on a slipping or shuddering unit builds heat that damages clutches, the valve body and the fluid.
Mercedes-Benz gearbox flaring
The revs rise between gears and the next gear arrives late, a sign of worn clutches, low pressure or valve body wear.
Mercedes-Benz automatic gearbox slipping
The revs rise but the car does not accelerate to match, or the gearbox drops out of gear.
Mercedes-Benz limp mode
The car holds one gear, often second or fifth, and limits power to protect the gearbox after logging a fault.
Mercedes-Benz gearbox warning light
A gearbox or transmission malfunction message means a code has been logged and needs reading.
Mercedes-Benz gearbox juddering
Shudder at a steady speed often points to the torque converter lock-up clutch, while judder from rest points to a dual-clutch.
Harsh or delayed changes
A bang into gear, harsh downshifts, or a long pause before the car moves.

Judder from rest on a dual-clutch usually points to clutch wear or a mechatronic fault, while shudder at a steady speed on a 7G-Tronic or 722.6 suggests the torque converter lock-up. A diagnostic finds the cause before anything is repaired.
Yes. Many faults, including valve body, conductor plate and solenoid faults, can be repaired without replacing the whole unit. Where wear is widespread, a full Mercedes-Benz gearbox rebuild is the lasting fix.
It often is, because a repair or rebuild is matched to the fault and comes with a 12-month parts and labour guarantee. We explain your options after a free phone diagnosis.
It depends on the gearbox type and the parts needed. Once the diagnosis is done we give you a realistic timescale.
The cost depends on the gearbox type, the fault found and the repair needed. Some faults are fixed by repairing individual components, while more extensive damage may need a rebuild. Call us to talk through your car.
Limp mode protects the gearbox by limiting power and gears, often leaving the car stuck in second or fifth. Avoid driving further than you need to and call us for a free phone diagnosis.
That is typically limp mode after a fault is logged, often a conductor plate, sensor or solenoid problem. A diagnostic reads the codes and confirms the cause.
The 7G-Tronic is Mercedes-Benz's 7-speed torque converter automatic. It is used across many models and shares a family of faults: conductor plate, valve body and solenoid wear.
We repair the 722.6, the 7G-Tronic and 9G-Tronic, the 7G-DCT and 8G-DCT dual-clutch gearboxes, the earlier CVT, and 4MATIC checks across the Mercedes-Benz range, vans included.
The model, engine and year decide it. Give us your registration and we will confirm the exact gearbox before we advise on a repair.
The most common are flare, harsh shifts, shudder at cruising speed, warning lights and limp mode. The usual causes are valve body and conductor plate wear, solenoid faults, torque converter wear and tired fluid.
It is described as lifetime fill, but fluid ages with heat and mileage and many faults begin there. A service at higher mileage can help, though it cannot reverse existing wear.
Yes. Towing raises fluid temperature and clutch loading, which accelerates wear on gearboxes that are not in good condition. Tell us if your Mercedes-Benz tows and we will factor it into the diagnosis.
Yes. Every repair carries a 12-month parts and labour guarantee, and we use OEM-approved parts as standard.
Yes. We arrange vehicle recovery, and bespoke collection and delivery is available with all repairs over £1,500.
Yes. If your Mercedes-Benz is covered by a warranty, we can undertake the claim with you as part of the repair.
We have 18 years of experience and have completed over 20,000 automatic gearbox rebuilds.
