What Causes the Abnormal Noise When Shifting to Third Gear?
1 Answers
The reasons for abnormal noise when shifting to third gear are as follows: 1. Automatic transmission water ingress: If water enters the automatic transmission and is not repaired in time, it may lead to a series of problems over time, such as oil leaks and abnormal noises. 2. Long-term failure to replace automatic transmission fluid: If the automatic transmission fluid is not replaced for a long time, it will become thicker. If it loses its effectiveness due to prolonged use, there will be no protective layer between components, leading to direct friction. This exacerbates the wear of mechanical parts and, in severe cases, damages components such as the automatic transmission planetary gear set and differential. Damage to internal parts can cause abnormal noises in the automatic transmission.
