Solutions for Transmission Abnormal Noise in Trumpchi GS4
2 Answers
Due to lack of lubricating oil or deterioration of lubricating oil causing noise, oil should be added or the oil quality should be checked and replaced if necessary. There is abnormal noise in neutral gear. Noise after pressing the clutch pedal indicates wear of the front and rear bearings of the transmission shaft. If noise occurs in any gear, it indicates severe looseness of the rear bearing of the second shaft.
The transmission noise issue with the Trumpchi GS4 requires detailed analysis. Common scenarios include: squeaking when depressing the clutch in neutral likely indicates a faulty release bearing, requiring transmission removal for replacement; metallic clunking during low-speed gear shifts suggests inspecting the dual-mass flywheel first - broken damping springs cause this hammering sound; whining during acceleration usually points to worn driveshaft bearings or differential gears, which can be checked by shaking the driveshaft underneath to assess play. A special case involves rattling noises during cold winter starts, often caused by insufficient valve body pressure leading to partial clutch engagement - switching to low-temperature fluidity transmission oil solves this. If you hear sounds resembling metal debris churning, immediately stop and check the drained oil - metal shavings in the pan necessitate major overhaul. Remember to change transmission fluid every 40,000 km during routine maintenance, and don't believe those 'maintenance-free' claims.
