Reasons for Severe Vibration When Braking in D Gear
1 Answers
The reasons for vibration when braking in D gear are as follows: 1. After severe clutch wear, 'sliding friction' may occur when stopping in D gear; because wear reduces the friction between the two, and sliding friction can cause abnormal vibrations, rapidly increasing the clutch temperature. Therefore, stopping in D gear at relatively low temperatures may result in regular resonance or abnormal noises. 2. All torque converters can also wear out, and severe wear cannot rule out the possibility of abnormal slipping; coupled with wear or looseness of the power output shaft, or issues with the transmission gear bearings, irregular resonance when stopping in D gear is highly likely. 3. Carbon deposits can cause engine idle vibration. When in D gear, the engine needs to output power, and the RPM will be slightly higher than idle speed; however, if the throttle, intake and exhaust valves, spark plugs, or fuel injectors have severe carbon buildup, the air-fuel mixture and combustion efficiency at low RPMs will deteriorate.
