What are the causes of gear grinding in cars?
1 Answers
The causes of gear grinding in cars are: 1. The reverse gear synchronizer is not installed; 2. The clutch is not fully disengaged when shifting gears; 3. The lubricating oil in the transmission contains large impurities, such as iron filings from long-term wear that get caught between the transmission gears during rotation, which can also easily cause gear grinding. The method for replacing transmission oil is: 1. Start the engine to warm up the transmission to operating temperature; 2. Remove the oil drain bolt; 3. After draining the old oil, reinstall the bolt; 4. Add new transmission oil; 5. Start the engine and shift from P to N, D, L1, L2, etc., pausing for at least 5 seconds in each gear; 6. Check if the automatic transmission fluid level is normal.
