The reason for the abnormal noise when shifting from first gear to second gear in Wuling Hongguang S may be due to improper timing of releasing the throttle or a mismatch between the gear and speed. Below is a detailed introduction about the Wuling Hongguang: 1. Overview: The Wuling Hongguang is the first independently developed crossover product between commercial vehicles and passenger cars launched by SAIC-GM-Wuling. This product features a smooth exterior design, a versatile and practical spacious interior. 2. Others: The fuel tank capacity is 50L. The standard seating capacity is 7. The seat material is leather. It is equipped with two engines, the P-TEC 1.2L and 1.5L-DVVT, designed and manufactured according to General Motors' global powertrain standards. While ensuring ample power, it demonstrates excellent fuel economy.
I've been delivering goods with my Wuling Hongguang for seven or eight years, and I often encounter a grinding noise when shifting from first to second gear. It's mostly caused by synchronizer wear, especially when the second gear synchronizer ring becomes thin, making gear engagement less smooth during shifting. Not fully depressing the clutch can also cause this issue—if the clutch isn't completely disengaged, there will be gear grinding noises during shifting. If the transmission oil hasn't been changed for too long and becomes thick, its lubrication effect diminishes, making shifting movements louder. Another possibility is loose shift cables or mounting bracket screws, which can create a vague shift feel and inaccurate gear engagement. When driving, remember to release the clutch gently and not too abruptly, and regularly check the transmission oil. If the noise persists, it's best to visit a repair shop immediately for a gearbox inspection to check the synchronizers.
