Can Transmission Noises Be Repaired?
1 Answers
Transmission noises can be repaired. Once an automatic transmission malfunctions, the vehicle owner should promptly send it for repair. If abnormal noises are ignored and the vehicle continues to be used, it may eventually lead to the vehicle not moving or even complete transmission failure. Therefore, once a transmission issue arises, it must be taken to a professional transmission repair facility immediately to avoid greater losses. The main causes of abnormal noises in an automatic transmission include: excessive wear of the oil pump or improper transmission fluid level (too low or too high), noise from the torque converter due to damaged lock-up clutch or one-way overrunning clutch in the guide wheel, noise from the planetary gear set, or noise from shift actuators. Solutions for transmission noises: Check the automatic transmission fluid level; if it is too high or too low, adjust it to the correct level. Use a lift to raise the vehicle, start the engine, and check the source of the noise in neutral, drive, reverse, and other gears. If there is continuous noise at the front of the transmission in all gears, it is usually due to the oil pump or torque converter. In such cases, the transmission should be disassembled for inspection. Check the oil pump for wear and the torque converter for excessive friction debris. Replace the oil pump or torque converter if abnormalities are found.
