Haval H6 uses two types of transmissions, one is a 6-speed manual transmission, and the other is a 7-speed dual-clutch transmission. The dual-clutch transmission is particularly suitable for use with small-displacement turbocharged engines. The Haval H6 uses two engines in total, one is a 1.5-liter turbocharged engine, and the other is a 2.0-liter turbocharged engine. The Haval H6 is the flagship model of the Haval brand, promoting the concept of 'safety without hierarchy'. It comes standard with a 71.61% high-strength steel body, a hot-formed steel integrated door frame, and 6 airbags, with the hot-formed steel strength reaching up to 2000Mpa.

My cousin bought a Haval H6 two years ago equipped with a 7-speed dual-clutch transmission. It shifts quite smoothly when driving, and there's no noticeable jerkiness even in traffic jams. His car is a 1.5T automatic, and I heard that this transmission system developed in-house by Great Wall has been in use for several years. Feedback from veteran owner groups indicates overall reliability is decent. However, some car owners mentioned that early production batches occasionally had slight clicking noises at low speeds, which could be resolved by visiting the dealership for a software update. The newer models now even come with an electronic gear shifter, which looks pretty cool. Last time I accompanied him for maintenance, the technician said this transmission is most vulnerable to long-term aggressive driving, and its lifespan can be extended by avoiding sudden throttle stomps in daily use.

There are several Haval H6s in our neighborhood. In the earlier years, the manual transmission models were equipped with a Getrag six-speed gearbox, which had a somewhat heavy shift feel but was quite durable. Nowadays, the automatic models mostly use the in-house developed 7DCT, which is said to have undergone three optimizations of the hydraulic control module. Once, I rode in a neighbor's new third-gen H6 and noticed that the transmission logic had become much smarter, automatically downshifting to maintain torque when going uphill. However, during cold starts in winter, the shifts can be slightly sluggish for the first two minutes, but once the oil temperature rises, it becomes smooth. The hybrid version uses a two-speed DHT, which is even more unique—when driven directly by the electric motor, there's no gearshift jerkiness at all.

Research shows the Haval H6's transmission configuration is quite complex. The first-generation automatic models used Hyundai Powertech's 6AT, later gradually replaced by Great Wall's self-developed 7-speed wet dual-clutch transmission. Currently, both the main 1.5T/2.0T fuel versions are equipped with this 7DCT, capable of handling up to 450Nm torque. The hybrid-exclusive Lemon Hybrid DHT employs a two-gear structure, more efficient than Toyota's single-gear system. Notably, the 4WD versions feature BorgWarner's TOD intelligent 4WD system that coordinates with the transmission, delivering exceptionally smooth gear shifts during automatic power distribution on snowy roads.
