Automobile automatic transmission, manual and semi-automatic transmission car, three different types of operation of motor vehicle, automatic transmission car is easiest, many opened automatic transmission cars have awareness in this regard, therefore automatic transmission car compared with those of other two kinds of car electronic devices will be more, should pay attention to in the maintenance of more, also need to use professional Auto Diagnostic Tool repair, therefore, compared with the other two cars, vehicle with an automatic transmission is more difficult to maintenance, here to introduce some automatic-shift cars maintenance knowledge.
1. Always check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, check the engine oil in the cold state, and transmission oil is needed to oil preheated to about 50 ℃, then to block a rod in each block for 2 seconds in a stop block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, it is timely to add the same quality oil.
2. Correct replacement of transmission oil. Presently preferred method is dynamic change oil, cleaning equipment using a dedicated gearbox, in the gearbox during operation, the old oil full circle, emissions clean, add a new gearbox oil, so oil change rate is as high as 90%, to ensure good oil effect.
3. Master replacement of automatic transmission oil cycle. Automatic transmission internal control mechanism is very precise, with a small gap, so most manufacturers recommend automatic transmission oil change is usually two years or 40,000 to 60,000 km. During normal use, the transmission fluid temperature is generally around 120 degrees Celsius, so the quality of oil in demanding, must also be kept clean, as well as regular use Launch X431 V Pro or Launch X431 V+ Pro3 tools to detect. Secondly, gearbox oil to use after a long time will produce grease, it is possible to form sludge, will increase the friction plate and the parts wear, but also the influence of hydraulic system, make the power transfer is affected. Third, the dirty oil sludge will enable each valve body moving smoothly, hydraulic control affected, so that the automatic transmission abnormal.
Automatic transmission vehicle maintenance and repair in strict accordance with the maintenance manual to repair, encountered do not understand the situation, do not go to their private to deal with, go to a specialized repair shop or 4S shops to consult professional people, but the best maintenance method is usually the correct use of the car, regular use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the car's overall situation.
