Why Does an Automatic Transmission Car Make Noise When Shifting Gears?
1 Answers
Here are the reasons why an automatic transmission car makes noise when shifting gears:1. Shifting gears without stopping completely: When parking, if the car is not completely stopped before shifting to P gear, the P gear lock hook inside the transmission will hit the gear, making a clicking sound.2. Incorrect operation sequence when parking on a slope: For an automatic transmission, the P gear relies on the lock hook to hold the gear in place to keep the car stationary. When parking on a slope, you should first apply the handbrake and then shift to P gear, allowing the handbrake to bear the downward force of the car.3. Worn transmission gears: The transmission is a precision component, and the gears best reflect its precision. However, due to tight meshing, wear is inevitable. Over time, larger gaps will form between the gear teeth, resulting in noise when shifting gears.
