What Causes Transmission Abnormal Noise?
1 Answers
Transmission abnormal noise is caused by: 1. Loose connection between the gear lever and shift fork groove in manual transmissions; 2. Loose bolts on the transmission housing; 3. Wear or damage to bearings; 4. Metal peeling on gear tooth surfaces, tooth breakage, or incorrect assembly; 5. Abnormal gear meshing clearance; 6. Water ingress into the transmission; 7. Insufficient lubrication due to inadequate lubricant. The transmission mainly refers to the vehicle's gearbox, which is divided into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions are composed of a torque converter, planetary gears, hydraulic torque variation system, and hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.
