What Causes the Abnormal Noise When Reversing in an Automatic Transmission?
1 Answers
Reasons: Damage to the reverse gear teeth, such as broken or chipped teeth; damage to the reverse gear bearing, or poor lubrication of the bearing causing friction noise. Below is an introduction to related content: 1. The role of the synchronizer: The synchronizer is a device inside the transmission that ensures smooth gear engagement when shifting gears while driving. 2. The principle of engaging reverse gear: The synchronizer makes shifting easier because it synchronizes the speed of the gears. However, reverse gear uses straight-cut gears, and when engaging reverse, the reverse gear meshes with two other gears. Only in this way can the car reverse.
