- Mar 01, 2018 -

1. Master the replacement of automatic transmission oil cycle.

Automatic transmission internal control mechanism is very precise, with small clearance, so most of the automatic gearbox oil exchange cycle generally for two years or 4~6 million kilometers. In the normal use of the process, the transmission oil operating temperature is generally around 120 degrees Celsius, so the quality of the oil requirements are very high, but also must be kept clean. Second, the transmission oil after a long time will produce grease, there may be formation of sludge, will increase the friction pieces and parts of the wear, but also affect the system oil pressure, so that the power transmission is affected. Third, dirty oil in the sludge will make the valve body in the movement is not smooth, oil pressure control is affected, so that the automatic gearbox abnormal. Check it regularly.

2. Replace the gearbox oil correctly.

The better oil change method is dynamic oil change, using special gearbox cleaning equipment, in the process of gearbox operation, the old oil full circulation, discharge clean and then add new gearbox oil, so that the oil exchange rate as high as 90, to ensure good oil change effect.

3. Automatic transmission oil level is normal.

Automatic transmission oil inspection methods and engine oil is not the same, engine oil in the cold car under the condition of inspection, and gearbox oil is required to preheat the oil to about 50 ℃, and then the retaining lever in each stop 2 seconds after the stop, at this time the normal oil oil level should be located between the highest and the lowest line, if not enough, The same quality of oil should be added in time.
