(Video) 722.9 Change Automotive Transmission Fluid and Filter During C

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 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!

Here is the video:
