　　Many automatic car owners, just buy a new car when the love has added. But a warranty period, for how the vehicle inspection, maintenance, repair, do not bother to make clear: "the car can be opened, can not be repaired."Please timely maintenance of the car gearbox（OBD Diagnostic Scanner）When the accident to send the car to repair, because there is no timely repair and maintenance, so that the automatic transmission of small fault expansion, deterioration and lead to major accidents.

　　That how to automatically block models for maintenance?

　　1 Often check the automatic transmission oil level is normal. Check method of automatic gearbox oil and engine oil is not the same, the engine oil in the cold state inspection, and transmission oil is necessary to preheat the oil to 50 degrees Celsius, then the gear lever in each gear position for 2 seconds after a stop block, then the normal oil level oil foot should be located in the most high. With the lowest line such as not enough, the same quality in time to add oil.

　　2 Master the cycle of automatic transmission oil. The internal control mechanism of automatic transmission is very precise, with the gap is small, so most manufacturers recommend automatic transmission oil cycle is generally 4~6 years or thousand kilometers. In the normal use of the process, the transmission oil temperature is generally around 120 degrees Celsius, so the quality of the oil requirements are high, but also must be kept clean. Secondly, the gearbox oil to use after a long time will produce grease, sludge may be formed, will increase the wear of the friction plate and the parts, but also the hydraulic system, the power transmission is affected. Third, the dirty oil sludge in the mobile body each valve in the poor hydraulic control of the affected, so that automatic transmission abnormal.

　　3 Changing transmission oil correctly. The oil present a better method is a dynamic change, the gearbox special cleaning equipment, in the operation process of the gearbox, the full cycle of the old oil, drained and then add a new gearbox oil, so oil change rate more than 90 to ensure a good effect of oil.
