Transmission of the Trumpchi GM6 is a product of the brand. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixed or stepped changes in the transmission ratio between the output and input shafts, also known as the gearbox. The functions of the transmission include: 1. Changing the transmission ratio to expand the range of torque and speed variations at the drive wheels. 2. Enabling the vehicle to reverse while maintaining the engine's rotational direction. Classification of transmissions: 1. Stepped transmissions utilize gear mechanisms with several fixed transmission ratios. 2. Continuously Variable Transmissions (CVT) can achieve any transmission ratio within a continuous range. 3. Integrated transmissions refer to hydromechanical transmissions composed of a torque converter and a geared stepped transmission.

Last time at the repair shop, I heard the mechanic talking about the Trumpchi GM6. The older model used a 6-speed automatic transmission, which is quite mature in technology. It's a traditional AT transmission structure, offering good smoothness when driving, especially with minimal jerkiness during city driving when following other cars. However, fuel consumption is slightly higher due to its more complex structure compared to dual-clutch transmissions. The hydraulic control module of this transmission requires regular . My neighbor's car started having sluggish gear shifts at 80,000 kilometers, but it became smooth immediately after changing the transmission fluid. The newer models are now called M6, and earlier versions are still quite common in the used car market.

The last batch of Trumpchi GM6 before discontinuation used the Aisin 6AT, which was a relatively generous configuration among family MPVs. The automatic transmission's shifting logic is somewhat conservative, and downshifts during sudden acceleration aren't particularly fast, but it excels in durability. When I drove a friend's model on a long trip, the engine speed was just over 2000 rpm at 100 km/h, and the noise insulation was better than that of dual-clutch transmissions. Remember not to exceed the 60,000 km maintenance interval, and the oil pan filter should be replaced at the same time. In the current used car market, selecting a nearly new model from the 2018 to 2020 model years offers great value for money.

Speaking of the GM6 transmission, it can be divided into two phases. The early models indeed featured a 6AT structure with a torque converter, making the creep function effective in traffic jams. However, the later hybrid version switched to an E-CVT, which is a hybrid-specific transmission combining an electric motor with a planetary gear set. I test-drove the hybrid version in Hainan, where the initial acceleration was entirely electric-driven, eliminating gearshift jerks, and the engine intervention felt like a continuously variable transmission. The two transmissions differ significantly in style, so it's important to clarify the version when purchasing a car.

The transmission type of the Trumpchi GM6 depends on the model year. The 2019 model uses a conventional 6AT, which is fuel-efficient during highway cruising but consumes up to 11L/100km in city driving. The 2021 hybrid version employs an Electronic Continuously Variable Transmission (E-CVT), primarily relying on planetary gear sets for power distribution. Having driven both, the AT version has slight shift sensations, while the E-CVT version offers smoother, more electric-like performance. A reminder for owners: the transmission fluid in older models must be changed every 4 years or 80,000 km to prevent valve body sticking.

The GM6 gasoline version is equipped with a 6-speed automatic transmission with manual shift mode. Last year, while helping a colleague inspect a , I noticed a characteristic of this transmission: gear shifts are slightly slower when starting a cold engine, but become very responsive once the temperature rises. During one disassembly, I observed that its torque converter has a lock-up function, which can form a rigid connection above 60 km/h to reduce fuel consumption. Note that low-viscosity transmission fluid should be used, and the OEM fluid used by dealerships performs significantly better than third-party alternatives. The hybrid version, on the other hand, features a dual-motor hybrid system and, strictly speaking, does not have a traditional transmission structure.
