More delicate than in manual, automatic transmission vehicle maintenance should be careful
Now the city’s traffic situation is getting worse, when the stop and go traffic jam, get out of a manual transmission car owners to cope with their tired. Thus, light, save trouble of Automatic car almost a majority of the city’s car of choice. Although Automatic vehicle handy convenient, but automatic transmission system is a very sophisticated assembly, in particular, tiptronic automatic transmission whose structure is complex. Therefore, when the automatic transmission failure, repair them, but very cumbersome and expensive. Given this, the automatic transmission need to be more attentive care and maintenance.
Regularly check gearbox oil
Automatic transmission is called in the ATF into the oil, in addition to its role in lubrication of cooling, more important is to transfer power between engine and gearbox. ATF oil temperature is generally 120 degrees Celsius, so the high quality requirements of the oil must also be kept clean.
Always check the automatic transmission oil level is normal. Automatic transmission oil check method and not the same as engine oil, engine oil cooling under examination, and transmission oil is needed to oil heated to 50 ℃, then gear the gear lever to stay in 2 seconds placed in parking gear, then the normal oil level oil foot should be in between the highest and lowest lines, such as not enough, the same quality in time to add oil.
General whether the proposed manual gearbox or automatic transmission up to 12 months or 20,000 km replacement of an automatic transmission oil, and some models use the manual was written 24 months or 40,000 km replacement. But these are only general recommendations, Beijing vehicle condition as a special sand more than the weather, road congestion, poor air quality, the proposed vehicle to regular inspections and timely replacement of ATF.
Correct transmission oil change
Generally replace the automatic transmission oil is removed when the big end of the screw automatic transmission oil to miss the old oil and then add new oil, but this can only replace about 30% of the new oil, but also 70% of the old oil still remaining within the gearbox. If the purpose of breaking way sump oil change, oil change can reach 70% rate, this fact had to ensure the transmission of health. But a better method is a dynamic oil change, oil change, using a dedicated gearbox cleaning equipment, operating in the transmission process, the full cycle of the old oil, drained and then add a new gearbox oil, so oil change rate as high as 90%.
GM, Toyota, Ford and other brands of automatic transmission coefficient of friction is different so different ATF oil can not mix. Mixed ATF, will cause damage to the gearbox friction plate, there clutch, brake slipping phenomena, serious friction plate will be destroyed
