Great Wall Haval M6 transmission is produced by Getrag. Getrag (Jiangxi) Transmission System Co., Ltd. is a joint venture between Germany's Getrag Group and Jiangling Motors Group, established as a provider of transmission technology products and services. It officially commenced operations in January 2007 in Nanchang, Jiangxi. The Great Wall Haval M6 transmission uses either a 6-speed manual transmission or a 7-speed wet dual-clutch transmission. A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the drive wheels, enabling the vehicle to achieve different traction and speed under various conditions such as starting from a standstill, climbing hills, turning corners, and accelerating. For the Great Wall Haval M6 transmission, the following points should be noted during daily use: Do not delay changing the transmission oil for extended periods. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing. Avoid coasting in neutral for long durations. While driving manual transmission vehicles, many experienced drivers tend to coast in neutral, but for automatic transmission vehicles, this can cause the transmission to overheat and may result in a noticeable jolt when shifting back into D (Drive) mode. Never shift into D/R (Drive/Reverse) before the vehicle has come to a complete stop. Many drivers, in an attempt to showcase smooth operation, shift directly into reverse while the vehicle is still moving, which can cause significant damage to the transmission gears and, over time, lead to gear grinding and other failures. Avoid frequently climbing steep slopes in D mode. When facing steep inclines, automatic transmission vehicles often overheat due to high load or may upshift prematurely, resulting in insufficient climbing power. In such cases, it is advisable to use manual mode to limit the gear to a lower speed or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. In the event of a breakdown, an automatic transmission vehicle should be transported using a flatbed tow truck, with the vehicle in N (Neutral) mode when being moved onto the tow truck. Using a tow rope or directly towing the vehicle is not recommended.

I remember researching the transmission configurations when helping my cousin pick up his Haval M6 a couple of years ago. When it was first launched in 2017, the manual version used Chongqing Qing Shan's 6MT, while the automatic version generously featured Hyundai's 6AT from South Korea. By the 2020 model, the manual transmission was replaced by Honeywell's own gearbox, while the automatic still kept Hyundai's. The most interesting part was the 2021 PLUS version, which fully switched to Great Wall's self-developed 7-speed wet dual-clutch transmission. This DCT30 transmission is quite advanced, featuring an oil cooling system and well-tuned shift logic for crisp performance. In terms of reliability, forum feedback from long-term owners shows that Hyundai's 6AT is indeed durable, while the new dual-clutch offers higher transmission efficiency and slightly better fuel economy, though occasional mild jerks can be felt during stop-and-go traffic.
