What to Do About Transmission Noise in a Buick Excelle While Driving?
2 Answers
Buick Excelle transmission noise while driving can be addressed as follows: 1. First, check whether the transmission fluid level is normal and if there are any metal particles or debris in the transmission fluid. 2. If the transmission fluid is fine, the issue might be due to worn bearings or gears inside the transmission. It is recommended to visit a 4S shop for repairs. Diagnostic methods for transmission noise are as follows: 1. If there is noise when the engine is idling and the transmission is in neutral, and the noise worsens when the handbrake is engaged but disappears when the clutch pedal is pressed, it indicates wear and looseness in the rear ball bearing of the first shaft and its bearing hole. 2. If the transmission produces uneven noise that intensifies when the handbrake is engaged and remains audible while driving, it is likely due to poor meshing of the constant-mesh gears. 3. If there is noticeable noise from the transmission when the engine is idling, and the noise increases with higher RPMs and turns into gear clashing, gently push and pull the gearshift lever. If there is significant vibration, it suggests misalignment of the original positioning of the transmission cover.
I noticed abnormal noises from the Buick Excelle's transmission while driving. First, don't panic—I'll immediately pull over to inspect the situation. The most common cause is insufficient or aged transmission fluid. I'll open the hood to check if the dipstick level is within the normal range. If the fluid appears black or contains debris, an oil change is needed. Another possibility could be bearing wear or internal component issues—I'll carefully listen to pinpoint the noise source. If there's a humming sound, severe wear may be present, requiring immediate stoppage to avoid further damage. A potential factor might also be a faulty oil pump or valve blockage, as this Buick model occasionally experiences similar issues. I strongly advise against continuing to drive—call a tow truck to send the car to a professional repair shop for diagnosis. Transmission repairs are costly, so early intervention saves money and hassle. I make it a habit to change transmission fluid regularly to avoid such troubles.
