The maintenance of transmission gears is crucial for ensuring the performance of the transmission and extending its service life. Here are some suggestions for maintaining the gears of the transmission:

1. Regularly change the transmission fluid: Transmission fluid is the key to gear lubrication and cooling. It should be replaced regularly as recommended by the manufacturer, and it is necessary to ensure the use of the appropriate oil.

2. Check the transmission fluid level: Regularly check the transmission fluid level to ensure it is sufficient. Insufficient oil can lead to excessive wear of gears and overheating of the transmission.

3. Avoid overloading: Do not use the gearbox for a long time under high-speed or heavy-load conditions to prevent the gears from being subjected to unnecessary pressure and wear.

4. Smooth gear shifting: When shifting gears, operate smoothly to avoid sudden acceleration or deceleration, reducing the impact and wear on gears.

5. Avoid coasting in neutral: Prolonged coasting in neutral can cause the internal temperature of the transmission to rise, increasing the wear of gears and oil.

6. Avoid towing: If towing is necessary, ensure that it does not exceed the maximum towing weight and distance specified by the manufacturer to reduce the burden on the transmission.

7. Regular inspection: Regularly check the transmission for any abnormal noise, vibration or oil leakage, as these could be signs of gear wear or damage.

8. Professional maintenance: If any problem with the transmission is detected, it should be inspected and repaired by professional maintenance personnel as soon as possible to prevent the problem from worsening.

9. Avoid sudden acceleration and braking: Sudden acceleration and braking will increase the load on the transmission, causing additional wear on gears and fluid.

10. Use the appropriate gear: Select the right gear based on the driving conditions and avoid driving at a low speed in a high gear or at a high speed in a low gear for a long time.

By following the above maintenance suggestions, the service life of the transmission gears can be effectively prolonged and the good performance of the transmission can be maintained. Regular inspection and maintenance are the keys to preventing transmission failures.
