3. Analysis of SWMG016at gearbox.
(1)DSI company 1928 was established in Australia, which is a professional automatic transmission company integrating research, development, production and sales. In the late 1980s, it provided an advanced electronic control 4-speed automatic transmission. In 2004, 6AT was successfully developed, and in 2005, 6AT hybrid gearbox was successfully developed. In 2009, DSI was wholly-owned by China Geely Holding Group and changed its name to DSIH. On 20 15, Sara group reached a strategic cooperation with Geely, and Sara group held DSI.
(2)DSI has two R&s； in Melbourne and Shanghai, Australia; D center, Xiangtan, Hunan (300,000 production capacity), Jining, Shandong (300,000 production capacity), Ninghai, Zhejiang and other production bases, mass-produced DSI6AT automatic transmissions.

(3) Sara DSI6AT products.
M04RWD6AT: It is a new generation of longitudinal 6AT with a torque capacity of 470nm；;
M05FWD6AT:M05 adopts measures such as optimizing the main box design and improving the oil control to optimize the transmission efficiency; Adopt a new generation of solenoid valve to improve the performance of hydraulic system accurately, and the torque can match 180 nm -350 nm.
M06FWD6AT:M06 is the world's leading technology pioneer 6-speed automatic gearbox. The overall product structure is the most mainstream and mature scheme in the world at present. Hydraulic control adopts the latest VFS, and the torque can match 150 Nm -260 Nm.
According to the maximum torque of SWMSwayG0 1.5t engine 2 12Nm, DSIM06 gearbox should be adopted.
Summary: DSI6AT is a high-performance 6-speed hydraulic automatic transmission that has been verified by DSI in Australia for many years. A larger speed ratio of 1 is helpful for the vehicle to start, and the 5th and 6th gears less than 1 are overdrive gears, which is helpful for improving fuel economy. The high-speed shift in DSI6AT gearbox is smooth, and there is no obvious abrupt feeling. Geely's wholly-owned acquisition of DSI makes its own brand qualified to produce automatic transmissions, and to some extent, it can get rid of its dependence on imported transmissions.
