Maintenance of automatic transmission vehicles Huangjiang中美imported car shop, maintenance of automatic transmission vehicles Huangjiang imported second-hand cars. Many owners of automatic transmission vehicles take good care of their new cars when they first buy them. But once the warranty period is over, they are too lazy to figure out how to inspect and maintain the vehicle: "If the car can still run, then run it until it breaks down and then repair it." Huangjiang second-hand cars. When accidents occur and the car is sent for repairs, due to lack of timely maintenance, small problems with the automatic transmission escalate and worsen, leading to major accidents. So, how should automatic transmission vehicles be maintained? 1. Correctly change the transmission oil. The better oil changing method currently available is dynamic oil change, using specialized transmission cleaning equipment. While the transmission is running, the old oil is fully circulated and completely drained before adding new transmission oil. This results in an oil change rate higher than 90%, ensuring a good oil change effect. Car owners should cultivate awareness of proactive inspection, maintenance, and upkeep. They can learn some basic knowledge about maintenance and carefully read the accompanying user manual, remembering necessary data points. Scientific vehicle maintenance ensures that the vehicle remains in good technical condition and guarantees driving safety. 2. Master the cycle for replacing automatic transmission oil. The internal control mechanism of the automatic transmission is very precise with small cooperation gaps. Therefore, most manufacturers recommend an oil change cycle of generally two years or 40,000 to 60,000 kilometers. During normal use, the working temperature of the transmission oil is usually around 120 degrees Celsius, so the quality requirements for the oil are very high, and it must remain clean. Secondly, after prolonged use, oil sludge forms which may turn into mud, increasing wear on various friction plates and components. It also affects the system's oil pressure, impacting power transmission. Thirdly, the mud in dirty oil causes valves in various valve bodies to move poorly, affecting oil pressure control and causing abnormal operation of the automatic transmission. 3. Regularly check if the level of automatic transmission oil is normal. The method for checking automatic transmission oil differs from checking engine oil. Engine oil is checked when the car is cold, whereas transmission oil needs to be preheated to around 50 degrees Celsius. Then, keep the gear lever in each gear for 2 seconds before setting it to park. At this point, the normal oil level on the dipstick should be between the highest and lowest lines. If it's insufficient, promptly add oil of the same quality.
