DSI Automatic Transmission Company of Australia is a professional automatic transmission company integrating R&D, manufacturing and sales. In 2009, DSI was wholly-owned by China Geely Holding Group. At present, Geely has built factories in Xiangtan, Jining, Chongqing and other places, and mass-produced DSI automatic transmissions, which have been mounted on Emgrand EC8, British SC7, Job and other models.

Advantages and disadvantages of DSI 6-speed automatic manual transmission;
DSI6AT adopts hydraulic torque converter with anti-skid control and lock-up clutch, which can meet the torque demand of 400n·m or even more, while ensuring sufficient backup safety factor. DSI6AT has the advantages of mature technical quality, manufacturing technology and supporting system, which ensures the reliability of use and the service life reaches 250000km.
During the test drive, Job's DSI6AT automatic transmission started under the same fuel supply. Under normal driving conditions, the gearbox shifts smoothly and there is no sudden feeling. To a great extent, it plays an indispensable role in setting the speed ratio of the transmission, and on the other hand, it has a great relationship with the cooperation of the engine. However, this transmission is a bit slow to downshift when stepping on the accelerator deeply. If this point can be further adjusted, I believe this transmission will reach by going up one flight of stairs.
Job's 6at gearbox has many shortcomings. 6AT is only an upgraded version of the early 4AT, which is relatively backward in technology and does not support small torque engines. So the practicality is actually limited. Moreover, the gearbox of DSI is mainly matched with a large displacement longitudinal engine, which is used in related rear-drive SUVs and cars. At present, most models are transverse engines, so its transmission efficiency, fuel economy, size, weight and other indicators are relatively poor.
