What transmission does the Changan Oshan X7 use?
2 Answers
Changan Oshan X7 is equipped with a 7-speed wet dual-clutch transmission, which comes from Changan's Blue Whale platform. Here is an introduction to the 7-speed wet dual-clutch transmission: 1. Its internal structure is similar to that of a manual transmission, using gear meshing for power transmission, resulting in shorter shift times and better power transmission efficiency. 2. Moreover, the dual-clutch transmission eliminates torque interruption, allowing the engine's power to be continuously utilized. This helps save fuel and provides excellent fuel economy. 3. Additionally, the wet clutch has a wider threshold for adjustment, eliminating the need for rapid shifts to control temperature like dry clutches, which can cause jerking and hesitation during use. Therefore, it offers better smoothness compared to dry clutches. 4. However, 7-speed dual-clutch transmissions commonly experience shaking and hesitation issues. This is because the dual-clutch's operation is computer-controlled, and during rapid acceleration, the upshift speed is not very fast, leading to noticeable hesitation when shifting from 2nd to 3rd gear. Furthermore, the maintenance costs in the long run are significantly higher than those of CVT models, as the transmission fluid required for replacement must be of higher quality. Compared to CVT transmissions, 7DCT transmissions tend to have more minor issues and a higher probability of requiring repairs.
I've been driving the Changan Oshan X7 for over a year now. It's equipped with a 7-speed wet dual-clutch transmission that shifts quickly and is fuel-efficient, making the drive incredibly smooth. The acceleration on the highway is particularly impressive, with no lag at all. My friends often comment on how stable this transmission performs. The downside is that there can be slight jerks during stop-and-go traffic at low speeds, and occasionally, a gentle press on the accelerator is needed to avoid it. However, it's very convenient for daily use. Remember to change the transmission fluid every two years during maintenance—don't wait until problems arise to fix it. A few hundred yuan each time can extend its lifespan. It's super agile in the city, and weekend trips on bumpy mountain roads are no problem. Overall, this transmission is quite reliable and makes daily driving much more worry-free.
