新車自動變速箱|在正常情況下，自動變速箱油需要每2年或每40，000公里更換一次(稱為ATF)，但這也取決于型號。不同的車輛要求不同，建議更換460000公里一次，經(jīng)常在擁擠的工況下，建議縮短維修里程。
New automatic transmission | under normal circumstances, the automatic transmission oil needs to be changed every 2 years or every 40000 km (called ATF), but it also depends on the model. Different vehicles have different requirements. It is recommended to replace every 460000 km. It is often recommended to shorten the maintenance mileage under crowded conditions.
舊車自動變速箱|二手車是指5年后或已維修變速箱4萬公里或每年維修一次，亞洲、美洲等4至6檔，24-4萬公里或每年維修一次的舊車，只要強烈建議每年維修一次即可。
Used car automatic transmission | used car refers to an old car whose transmission has been repaired for 40000 km or once a year after 5 years, and whose transmission is in 4-6 gears, 240000-40000 km or once a year in Asia and America, as long as it is strongly recommended to repair once a year.
更換變速器的機油時，必須將原機油盡可能清潔。自動變速器的機油冷卻器都沒有卸油口。除少數(shù)型號外，大多數(shù)液力變矩器沒有卸料口，控制閥體內(nèi)的大部分油不能排出。按照傳統(tǒng)的方法，只有大約60%的油可以從油底殼中釋放出來。這種排油方式的效率無疑是不理想的。目前有兩種較好的排油方法。一種是在熱車狀態(tài)下用自動變速器代替燃油裝置，使90%以上的舊油可以噴射出來。
When changing the transmission oil, the original oil must be as clean as possible. The oil cooler of automatic transmission has no oil drain. Except for a few models, most hydraulic torque converters have no discharge port, and most of the oil in the control valve body cannot be discharged. According to the traditional method, only about 60% of the oil can be released from the oil pan. The efficiency of this oil drainage method is undoubtedly not ideal. At present, there are two better oil drainage methods. One is to replace the fuel device with the automatic transmission in the hot vehicle state, so that more than 90% of the old oil can be injected.
必須更換制造商指定的機油。自動變速器油可用于其他系統(tǒng)，如轉(zhuǎn)向系統(tǒng)。但是，不允許在自動變速器中添加其他油，如在自動變速器中不小心添加手動變速器油，在一定距離(約100~200km)行駛后，所有離合器和制動器都會受到嚴重腐蝕。
The oil specified by the manufacturer must be replaced. Automatic transmission fluid can be used in other systems, such as the steering system. However, it is not allowed to add other oil to the automatic transmission. For example, if the manual transmission oil is accidentally added to the automatic transmission, all clutches and brakes will be seriously corroded after driving a certain distance (about 100 ~ 200km).
在自動變速器油中添加摩擦修飾劑，以確保離合器和制動器能夠在潮濕狀態(tài)下可靠地傳遞扭矩。不同的自動變速器有不同的負載。添加到自動變速器油中的摩擦修飾劑也有所不同。因此，自動變速器必須取代制造商指定的機油。如果添加來自不同制造商的油，可能會發(fā)生換檔沖擊、離合器和剎車打滑，在嚴重情況下還會出現(xiàn)齒輪跳躍。
Add friction modifier to the automatic transmission oil to ensure that the clutch and brake can reliably transmit torque under wet conditions. Different automatic transmissions have different loads. The friction modifiers added to automatic transmission oil are also different. Therefore, the automatic transmission must replace the oil specified by the manufacturer. If oil from different manufacturers is added, shift shock, clutch and brake slip and gear jump may occur in severe cases.
