Car transmission noise can be caused by: 1. Worn or damaged bearings; 2. Loose transmission housing bolts; 3. Excessive clearance between the gearshift lever and shift fork groove in the transmission; 4. Long overdue transmission fluid change; 5. Use of inferior automatic transmission fluid; 6. Gear meshing clearance issues; 7. Gear tooth surface metal peeling, tooth breakage, or misalignment during assembly; 8. Water ingress into the transmission without timely repair. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixed or stepped changes in the transmission ratio between the output and input shafts. It is categorized into stepped transmissions, continuously variable transmissions, and integrated transmissions.
