What is the relationship between Qingshan Transmission and Changan?
2 Answers
The relationship between Qingshan Transmission and Changan is that Qingshan Transmission Factory belongs to China Ordnance Equipment Group Corporation, the same parent company as Changan Factory. Below is an introduction to transmission-related content: 1. 6AT Transmission: Except for shifting from P to D at the start and from D to P when parking, the D gear can be used from beginning to end. The Sport mode can be used when starting, but on flat roads, starting in Sport mode does not accelerate as quickly as in D mode. The S gear has excellent acceleration performance and is used for overtaking after reaching a certain speed. While driving, shifting the D gear to the left switches to M mode, where the gear lever can be pushed forward or backward to control the gear. 2. Classification: Automotive transmissions can be divided into manual transmissions and automatic transmissions, with AT being the commonly referred automatic transmission. Generally, automatic transmissions have gears such as P, R, N, D, 2, 1, or L. A 6AT indicates six forward gears, meaning six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the leading numbers differ, they are all derivatives of automatic transmission technology.
Speaking of the relationship between Qingshan Transmission and Changan, as a mechanic who frequently repairs various models, I must say they are long-time partners in the industry. Qingshan Transmission primarily manufactures automatic and manual transmissions, while Changan Automobile is a major client, with popular models like the Changan CS75 and Eado using components supplied by Qingshan. This collaboration is built on long-term trust, with strict processes in place from production to quality control—for example, Qingshan customizes transmissions to match Changan’s engine systems, ensuring smooth driving and fuel efficiency. However, common issues like gearshift delays often arise during repairs, usually due to software calibration or part aging, requiring regular maintenance. Changan’s choice of Qingshan aligns with cost control and localization strategies, which translates to lower maintenance costs and faster service for users. Overall, this supplier relationship is stable and reliable, supporting the competitiveness of domestic vehicles. I recommend owners pay attention to transmission fluid replacement cycles to extend service life.
