GLC's transmission is produced in Germany. The vehicle is equipped with a 9-speed automatic manual transmission, which is the first longitudinally mounted transmission developed by Mercedes-Benz. The automatic manual transmission combines manual shifting and automatic shifting, reducing power loss in the transmission system during operation. Parameters such as the gradient, steering angle, forward direction, roll angle, throttle scale, and braking degree of the Mercedes-Benz GLC are all displayed in real-time on the central display, making the center console appear clean and tidy. The vehicle has a rich array of comfort and safety features, with personalized settings that can greatly meet the driver's needs.

















I've researched Mercedes-Benz's supply chain myself, and the GLC's transmission is indeed an interesting topic. Mercedes now mostly uses its own 9G-Tronic automatic transmission, this 9-speed gearbox is primarily manufactured in Germany with very high technical sophistication. However, specifically for the GLC, there are different scenarios - for example, the domestically produced GLC L long-wheelbase version initially used a 7-speed transmission, but has now been upgraded to the 9-speed. As a core component, the place of production doesn't significantly affect quality, since Mercedes maintains uniform quality control standards globally. My friends who drive GLCs all say the gear shifts are exceptionally smooth, especially noting that low-speed jerkiness is better controlled than in other luxury brands.

From an automotive engineer's perspective, Mercedes-Benz's transmission strategy is clear: high-end models use in-house developed products. The 9G-TRONIC equipped in mainstream models like the GLC is indeed manufactured in Germany, but its modular design ensures consistent global quality. Here's an interesting fact: this transmission's torque converter features centrifugal pendulum technology, effectively reducing vibrations. In actual driving experience, it can shift into 9th gear at just 80km/h, delivering excellent fuel economy. During , technicians should pay special attention to inspecting the transmission mount bushings, as aging in this area can affect shift quality.

Recently helped a friend pick up a GLC 300 and specifically checked the parts information on the customs declaration. The imported 9-speed transmission's outer packaging had a prominent 'Made in Germany' label. The salesperson explained that all current GLC models, whether 260 or 300, come with German-made transmissions that have excellent compatibility with the engine. The most noticeable driving experience is how intelligently it shifts gears, capable of dropping directly from 9th to 4th gear when the accelerator is pressed hard. It's recommended that owners frequently use the manual shift mode, especially during long downhill drives in mountainous areas, to effectively protect the braking system.
