Mercedes-Benz S-Class automatic gearbox repair for flagship cars
An S-Class asks a lot of its gearbox, and a specialist repair is often worth far more than a replacement car.
The S-Class has used the 5-speed 722.6 on earlier cars, the 7G-Tronic on the W221 and W222 and the 9G-Tronic on some W222 and W223 models. V8 and V12 versions handle more torque.
Typical complaints are harsh shifts, delayed engagement, shudder, fault messages and limp mode. Electronic faults can combine with the car's many control modules.
We repair and rebuild S-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 S-Class has.
Why use a Mercedes-Benz S-Class gearbox specialist
With an S-Class, a precise diagnosis matters, because many systems share warnings. A Mercedes gearbox specialist isolates the gearbox fault. Call 0808 164 0418 to speak to a gearbox specialist about your Mercedes-Benz S-Class.
