Now city traffic condition is getting worse, car stop-go situation has become the habit of the driver. So, portable, easy these two features automatic car has quietly become the first choice for most people. Although automatic car easy and convenient, but because of the automatic transmission system is very sophisticated, if the automatic transmission fails, we need to use a professional OBD Diagnostic Tool repair, and expensive, and therefore, the automatic transmission need to be more careful care and maintenance.

The automatic transmission oil can not only play the role of lubrication cooling, but the main thing is to transfer power between the engine and gearbox. Lubricating oil temperature is generally around 120 degrees Celsius, so demanding on the quality of the oil, and must be kept clean. First frequently used Launch X431 V Pro or Launch X431 IV GX4 Master tool to check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, need to be preheated to about 50 ℃, the gear lever again after a short stay in each block in the parking and the oil dipstick corresponding normal oil level should be between the highest and the lowest line, if not, should be added in time.

In most cases, when we replace the automatic transmission oil is to remove the screw automatic transmission oil pan to miss the old oil then add new oil, but this can only put about a small part of the new oil, and there Most of the old oil remains in the gearbox. If demolition sump oil change way, you can put 70 percent of the new oil, so as to ensure the transmission of health. Presently preferred method is dynamic oil change oil change, using a dedicated gearbox cleaning equipment, the full cycle of old oil, drained and then add new oil, so that the oil change rate of 90%.

As the vehicle traveling road is rather special, road congestion, poor air quality, is easy to cause transmission oil oxidative deterioration, according to Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool inspection data indicate that the deterioration of the transmission oil increased wear of friction between the film and increase fuel consumption, if not to change new gearbox oil for a long time, will cause oil particles increases and block oil, blocking the plunger, and even a shift impact, so the transmission oil must be replaced periodically.
