【Why Do You Need ATF Exchanger?】The transmission oil will go bad after a prolonged period using of auto transmission, If you can't exchange the oil on time, it may causes the gearbox work abnormality.In the past, you need to spend more than 1 hour to disassemble multiple parts of the automatic transmission to drain the waste oil, and you didn’t know how many liters oil you should add into the transmission. If you add too much or too little, the transmission may be damaged. By using this machine, you can exchange the oil thoroughly within 20 min and you don’t need to worry about the quantity.

【Latest Design】 AUTOOL ATF705 auto automatic transmission oil changer adopts the world's latest process design. According to the combination of the circulating cooling pressure of the auto automatic transmission oil itself and the output pressure of this system, new oil is injected into the automatic transmission at the same time as the old oil is output. This synchronous circulating oil change mode not only ensures safe and efficient oil change of the automatic transmission, but also makes it thoroughly maintained.

【Full Automatic Operation】The whole process of oil change is automatic and intelligent, without manual operation. It is unnecessary for operators to distinguish the oil inlet and outlet pipesand the equipment can automatically identify andchange the direction of oil inlet and outlet. It can automatically identify the positive and negative polesof power supply , avoid safety accidents caused by reverseconnection of power supply , and ensure the safety of operatorsand equipment .The built-in high-precision electronic scale ensures equal exchange ofnew and old oil , and ensures that the automatic transmission systemcan return to normal state after each oil change and maintenance .

[Smart Exchage]: No manual operation required, the whole process of oil change is automated and intelligent.

[Cycle-Cleaning Function]: ATF705 adopts the scientific method of first cleaning and then replacing during the oil change work to ensure that the transmission system is clean and the old oil is completely discharged.

[Autimatic Equal Exchange]:The built-in high-precision electronic scale ensures equal exchange of new and old oil,and ensures that the automatic transmission system can return to normal state after each oil change and maintenance.
