1) Modular layout: improve versatility of the components: the shifting control unit adopts electropneumatic type, no gear selection mechanism, faster shifting, compact structure, high reliability;

2) The main box adopts sliding gear sleeve, which has low cost and high reliability; The auxiliary box adopts synchronizer to reduce the shift impact and improve the high and low gear switching speed. Auxiliary box adopts helical teeth with advantage of low noise and smooth operation;

3) The main box is equipped with countershaft brake to shorten synchronizing time, reduce shifting impact and improve shifting smoothness;

4) All aluminum alloy housing, light weight (165KG);

5) Software innovation: advanced automotive electronic control development management platform and tool chain for management and development.
