From the general direction, car gearboxes can generally be divided into manual gearboxes and automatic gearboxes. The manual gearbox has the advantages of easy maintenance, long service life, and fuel economy. The automatic transmission has the characteristics of easy operation, difficulty in maintenance, high maintenance cost, and relatively more oil than the manual transmission.
Gearboxes are more expensive in automotive parts and are an important large item. Therefore, the maintenance of the gearbox is particularly important. Once improperly maintained, it will cause difficulties in maintenance and will cost higher maintenance costs. Therefore, the transmission should be properly maintained.
The inspection of the gearbox is very simple. Normal manual gearboxes have no oil leakage, smooth gears, and no abnormal noise. The automatic transmission generally looks through the detector to see if each sensor works properly, whether there is abnormal sound, whether there is leakage, and whether the various gears work smoothly. If everything is normal, it is considered as good.
Of course, a good gearbox can't miss the quality inspection of transmission oil. General oil causes dirty oil, deteriorated oil, and impurities in the oil due to long-term use. This situation occurs when the transmission is considered to be worn out and the oil is generally cleaner, so the gear wear is considered to be small.
Most of the damage to the gearbox is caused by improper use or improper maintenance. If the gearbox is found to be abnormal, early detection, early maintenance, and early maintenance should be done. Otherwise, the loss will be large. Daily maintenance is often due to water or minor faults are not repaired in time, resulting in damage to the gearbox or even scrapped. Gearbox maintenance should be diligently checked, and gearbox oil and filter should be replaced. Change the oil to meet the standard oil products, oil change cycle due to people, driving environment, driving habits vary, generally recommended 3 ~ 60,000 kilometers to replace the gearbox oil. High-quality transmission oil guarantees excellent lubrication, heat dissipation and noise reduction. The filter must use high-quality, in principle, in exchange for good and harmless.
