自動擋汽車成為眾人心目中的選擇，一大部分原因在于操作簡單之外。意義上自動擋變速箱相對于手動的更不容易出現問題，但有優勢的同時，必然有弊的一面。
Automatic transmission car has become the choice in people's mind, mostly because of its simple operation. In a sense, automatic transmission is less prone to problems than manual transmission, but it has advantages and disadvantages.
自動擋變速箱在結構構造上就與手動不同，發生故障時，更難檢修，后期需要的維護養費就會多一些。
The structure of automatic transmission is different from that of manual transmission. In case of failure, it is more difficult to repair, and the maintenance cost will be more in the later stage.
雖然自動變速箱的拆裝和維修等需要人員進行操作，但具備一定的方法去判斷車輛的狀態，還是有好處的一、出現打滑或者沖擊現象
Although the disassembly and maintenance of automatic transmission requires personnel to operate, it is beneficial to have certain methods to judge the state of the vehicle. First, there is slip or impact
如果掛上D檔或R檔車子不走，或者車子反應很遲緩后沖擊，或者發動機轉速很高但車速卻很慢，就意味著變速箱內部的機械傳動部分出了問題。
If the car doesn't go in D or R gear, or the car reacts very slowly, or the engine speed is very high but the speed is very slow, it means that there is a problem with the mechanical transmission part inside the gearbox.
二、換擋時間太長或者過短
2、 Shift time is too long or too short
一般自動變速箱都是有特定的換擋轉速和車速。如果發現換擋時間突然過長或者過短，這就意味著變速箱的傳動比不成比例了。
Generally, automatic transmission has specific shift speed and vehicle speed. If the shift time is suddenly too long or too short, it means that the transmission ratio is out of proportion.
同時會感覺發動機的轉速過高，情況更甚者是變速箱不進行換擋，這都說明變速箱出了問題。
At the same time, I feel that the speed of the engine is too high. What's more, the transmission does not shift, which indicates that there is a problem with the transmission.
三、故障異味
3、 Fault odor
變速箱體是靠液壓油來工作的，當油溫過高時，會產生一些燃燒，這些異味會傳出來，這就說明變速箱體內的某些執行部件工作不正常。
The gearbox works by hydraulic oil. When the oil temperature is too high, some combustion will occur, and these peculiar smell will be transmitted, which indicates that some executive parts in the gearbox do not work normally.
對于汽車自動變速器出來故障，一部分因為很多知識和技術不到位，以及廠商的原因，都是直接更換高昂價位的部件。這看似明顯車主被坑了，但不想被坑自己也解決不了。
Some of the reasons for this are the high cost of the parts and the lack of technical knowledge from the auto manufacturers, as well as the failure of the automatic transmission. It seems obvious that the car owner has been cheated, but if he doesn't want to be cheated, he can't solve it by himself.
所以學會辨別一些小的故障問題，很大程度可以避免大范圍的進行檢修，減少維修費用。
Therefore, learning to identify some small faults can largely avoid large-scale maintenance and reduce maintenance costs.
總結：
Summary:
百分之九十的故障都是自動變速箱油過熱導致的，給自動變速箱內形成了頑固性的臟污與雜質，堵塞閥體，無法控制油壓。
Ninety percent of the faults are caused by overheating of the automatic transmission oil, which forms stubborn dirt and impurities in the automatic transmission, blocks the valve body and cannot control the oil pressure.
