Whether the gearbox oil must be periodically replaced? First of all we know about the role of the gearbox oil: we all know that the gearbox is from a lot of gear and shaft combination, rely on the transformation of different size gear combinations of variable speed pitch, the structure is divided into a plurality of input shaft and the output shaft, the input shaft of the power transmission in representative from the engine, a plurality of output axis represents each gear, the power is transmitted to the wheels.
Since it is between the gear teeth, it must be the middle of the gearbox oil to wear and lubrication, the gearbox oil shoulder in gear lubrication, cooling, the establishment of hydraulic effect, with low temperature resistance at low temperature can be very effective for the lubrication effect, in the harsh operation conditions to reduce the loss of oil. According to the different structure of the gearbox, gearbox oil is divided into automatic gearbox oil and gearbox oil.
Depending on the hydraulic automatic transmission gear to complete the transform action, so the automatic transmission oil must be designed special oil, transmission oil now special oil automatic transmission fluid is used for hydraulic torque converter and the hydraulic oil, lubricating oil and the structure of planetary gear shifting device, manual transmission is not the same, to complete shift action through the fork, does not need to be tailored to meet the requirements of hydraulic oil, gearbox oil gear oil can be used in general.
What happens if you don't change the gearbox oil for a long time?
The transmission box of metal gear set and a friction plate in high speed operation, will produce metal chips, particles, grease and dirt, and these pollution with transmission oil to wear in the inner loop, the gearbox oil in the long-term high speed working under high temperature to metamorphic volatile, thus aggravate the wear of mechanical parts. Serious bad transmission gear, shaft, bearing is normal, the term does not replace the gearbox oil, gearbox oil can become strong, easy to make the gearbox radiator is blocked, resulting in high transmission oil temperature, increased wear.
Of course, the work intensity of the gearbox is far better than the engine work intensity is so big, the working environment and be quite different but this does not mean the engine, gearbox oil neverdeteriorates, maintenance long time not assuming gearbox, so in normal use, the impurity cleaning power transmission oil can be produced by adding working speed oil box daily, resulting in abnormal wear block transmission system, flow of hydraulic torque converter oil differential gear, slow response.
In addition, the oil changed long time itself will produce large amounts of sludge and corrosive, will affect the service life of the gear box, so, never change gearbox oil vehicles have a great chance to appear such as lifting gear difficulties, frequent jump stop with an obvious impact into the file, if the above situation again, not pay attention, the gearbox will soon be scrapped.
Whether you go to any home repair factory, because there are a lot of transmission oil change without leading to the existence of scrap gearbox case, and from the gearbox replaced oil quality, the use of more than four years of transmission oil is obviously bad, black, thick, foul tendency not to mention the hundreds of thousands of kilometers, did not change the oil in the gearbox.
The so-called does not find the problem, but many car owners are not very sensitive to the abnormal situation of the vehicle, does not mean that the gearbox is really a little problem, in other words, no scrap, only to show you luck.
Compared to replace the gearbox oil, replace the transmission cost is much higher, many brands of gearbox assembly price in the 2-5 million, the luxury brand price is as high as 100 thousand, while embarrassing, a car for six or seven years and only 1/3 of the original value of the car, so how to choose to change or not to change.?
The new car automatic transmission | required every 2 years or every 40 thousand km to replace a automatic transmission oil in general (ATF), but also depends on models, different models have different demands, proposed 4-6 million kilometers to replace one, often in congestion conditions, reduce the mileage maintenance suggestions.
The old car automatic transmission car | refers to after 5 years or had repaired gearbox, 40 thousand kilometers or yearly maintenance, Asia, America 4-6, 2-4 million kilometers or yearly maintenance, as long as the gearbox repaired strongly recommended maintenance once a year.
In the automatic gearbox oil field, Fuchs industry is recognized as the leader of Germany, the German Fuchs automatic gearbox oil covered 95% models and transmission, installation supporting Bugatti, Ferrari, Porsche, Mcclaren, GTR, Benz, BMW, Audi, Volkswagen, ZF, GM, BYD, SAIC, JAC Getrag.
