722.9 automatic transmission is very popular in Mercedes-Benz and served from 2006-2017. It has 7 forward gears and 2 reverse gears.
Every 7 years/70,000 miles (made after 06-22-2010) or 4 years/40,000 miles (made before 06-22-2010) we have to change the automatic transmission fluid and filter of our Mercedes, that's requiring of Mercedes maintenance booklet. If your vehicle was equipped 722.9, that’s the most same process to change ATF and filter like this video, whatever made before or after 06-22-2010. For this vehicle (W212M276), the drain plug of the torque converter is difficult to operate, so I drill a hole on the shell to working easily. Something won’t happen on my W221M278. Another notice, if your vehicle made before 06-22-2010, the fluid is red and the overflow plug is withe, otherwise the fluid is blue and the overflow plug is green. Just like other maintenance, change ATF is not a difficult job, just be patient. Good luck!

722.9是奔驰一款用途广泛的自动变速箱，服役于2006年至2017年，具备7个前进档和两个后退档。
根据奔驰维修手册的要求，每7年/7万英里（2010年6月22日之后出厂），或者每4年/4万英里（2010年6月22日之前出厂）必须更换变速箱油。如果您的车装备了722.9的变速箱，换油过程是几乎一样的。在W212（M276）这款车上，液力变扭器的放油口位置不能很好地操作，所以在视频中，我需要在壳体钻一个孔，以方便操作。同样的事情不会发生在我另一辆车W221M278上。另外需要注意的是，2010年6月22日之前出厂的变速箱油是红色的，溢流管是白色的，而2010年6月22日之后出厂的变速箱油是蓝色的，溢流管是绿色的。更换变速箱油是一项普通的保养工作，不难，只需要您付出耐心，一定成功！
