In our daily life, the car has become an important part of life, now the popularity of automatic cars is more and more, in automatic cars, automatic transmission is an important part, in the process of operation, ATF flows continuously. Today we will learn about the cleaning of parts in automatic transmission maintenance. The oil circulation of automatic transmission is as follows:

　　1. 油泵由發動機驅動，從油底殼中抽出自動變速箱油。ATF通過主調壓閥進入液壓閥體的主調壓閥，部分ATF通過主調壓閥進入液壓變矩器。

　　1. The oil pump is driven by the engine and draws the automatic transmission oil from the oil pan. ATF enters the main pressure regulating valve of the hydraulic valve body through the main pressure regulating valve, and part of ATF enters the hydraulic torque converter through the main pressure regulating valve.

　　2. 進入液力變矩器前，通過液壓閥體內的鎖緊調壓閥調節ATF;

　　2. Before entering the hydraulic torque converter, adjust the ATF through the locking pressure regulating valve in the hydraulic valve body;

　　3.ATF流經液力變矩器后，將流經散熱器。由于散熱器位于變速器的外部，ATF從變速器流出，然后通過散熱器的回油管再次進入變速器。

　　3. After flowing through the torque converter, ATF will flow through the radiator. Since the radiator is located on the outside of the transmission, ATF flows out of the transmission and then enters the transmission again through the return line of the radiator.

　　4. 二次油回路通常稱為潤滑油回路，用于潤滑行星齒輪等機構，以避免過熱和燃燒。

　　4. The secondary oil circuit is usually called lubricating oil circuit, which is used to lubricate planetary gear and other mechanisms to avoid overheating and combustion.

　　5. 潤滑油回流到變速器底部的油底殼，完成一個循環。隨著油泵的連續運行，自動變速箱油循環往復。

　　5. The lubricating oil returns to the oil pan at the bottom of the transmission to complete a cycle. With the continuous operation of the oil pump, the automatic transmission oil circulates.

　　因此，在自動變速箱的維護工作中，對零件的清洗和清洗是很重要的。通常我們用煤油清洗零件。為了省錢，一些維修店反復用少量煤油清洗零件，然后用壓縮空氣烘干。自動變速箱的故障不斷被修復，而新的液壓閥體保持不變。雜質已進入液壓循環系統的自動變速器。在這種情況下，必須對整個液壓系統回路進行清洗和清理，以便進行故障排除。

　　Therefore, in the maintenance of automatic transmission, it is very important to clean and clean the parts. Usually we clean the parts with kerosene. In order to save money, some repair shops repeatedly use a small amount of kerosene to clean parts, and then use compressed air to dry them. The failure of the automatic transmission is constantly repaired, while the new hydraulic valve body remains unchanged. Impurities have entered the automatic transmission of the hydraulic circulation system. In this case, the entire hydraulic system circuit must be cleaned and cleaned for troubleshooting.
