This video was added some important footages I lost in the previous video, one is shifting through "P-R-N-D" several times while the vehicle stationary and the engine idling after filled all of the ATF and waiting for the temp rising. Another is to replace the crush washer of the ATF pan's drain plug. sorry for the inconvenience.

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!

这个视频加上了一些非常重要的细节，一个是在灌进全部变速箱油后，等待升温的过程中要换挡几次；另一个是要更换放油螺丝的密封铜垫片。非常抱歉给您带来的不便！
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！

Finally, a correct video showing the full transmission service and not like all the other half-ass videos that only show the transmission oil being changed,, which does not get the other 2 liters of oil out of the torque converter. This video ALSO shows how to access the torque converter drain plug and how to replace the remaining ATF OIL. THANK YOU!!!!

[@JorgeLopez-ub8dz]

Im always amazed how a group of top notch engineers could not come up with a more convenient and easier way to change this fluid. My 1960’s chevy Nova has a drain plug on the transmission pan and you fill the fluid through the dip stick pipe. Changing the fluid take a wrench and a funnel. Good job though, cant believe you had to drill a hole to be able to access the torque converter dran plug.

[@LeighSr]

Wow, 1960’s Chevy Nova! That’s amazing! Thanks for your compliment! And yeah, the top notch engineers make our life convenient, comfortable, but make our work difficult...even we have to makeup their mistakes of design 😂😂

[@geoffreypereira8024]

The complexity is the point :-)

[@chantakzee]

They don't want you to change the fluid at all, they are expecting you to change the car when the "lifetime" of the car is up, namely when your warranty is over.

[@KhKh-626]

Best oil change video ever made. no drama only work .

[@NitroNukeX]

Absolutely best video! I have also tried this at home and there is an extra procedure if you have the START/STOP function of removing the auxiliary pump. Also, for me, I had a hard time on replacing the pan gasket first time as the pan gasket easily gets twisted and leaks fluid once you fill-up the fluid so had to do all over again. For those doing first time transmission fluid changes, please be careful when attaching pan gasket!

[@LeighSr]

Thank you and yes, I use to experienced the ATF leaking due to the gasket moving. Double check even triple check the gasket before install.

[@gusf8451]

[@atvstel]

Clean, detailed and accurate video, especially the 4Nm and then the 180 degrees. You did it all right! No mistake. But, there is room for improvement if it is okay to accept a suggestion. By the way, when you drill on any metal in the future, put a magnet about a centimeter distance next to drilling so it can catch all the filings regardless if you'll use a magnetic sweeper later or not. The improvement is next time let the car do the complete flush for you by placing a tubing on the exit line of the 722.9 while the engine is running. At the same time keep adding new fluid. It is located on the side of the 722.9 close to its front. Look at the side of the transmission (of the passenger side) and you'll also need two new rubber seals to replace them after you are done. It's impressive how organized you are. Every tool has a home!

[@LeighSr]

I appreciate your compliment. The magnet to collect the metal debris is a good idea, I'll try it next time for drilling steel or iron. Just the shell of the TC bell is aluminum. To flush out the transmission and the torque converter is the process to replace the ATF w/o replace the filter. I listed the guiding document at the end of the page www.leighsr.com/atf-change-7229. Thanks again for your comment and I'll happy to discuss it at the www.leighsr.com/forum/ben-chi-lun-tan-mercedes-benz-forum/about-7g-atf-change

[@atvstel]

@@LeighSr Thank you for posting the PDF documents. They are all helpful. The document named "Flush out automatic transmission and torque converter" is what I was referring to. What I called exit line is the number 2 feed line. That is the proper term I should use. In your document it says to clean the vicinity of the line to prevent any contamination. Thank you again for the documents.

[@fixingproblems3183]

You only need to remove the oil cooler or return line if you are trying to do a complete flush. Dealers don’t even do TC when they charge you 650 for it. What is did was per MB bulletin/manual. Doing a complete flush is over kill.

[@markholland1578]

In keeping your video relevant, let me first start by saying Thank You! For giving us a thorough understanding of what it takes to change our transmission fluid and filter. I would only like to provide an update on my own experience with my 2012 E550 4.7 liter twin turbo transmission fluid change as it appears to be different insofar as the torque converter. I approached my local Mercedes Benz dealer here in Florida who explained they would not change the fluid within the torque converter and would charge close to 400 USD which included fluid and filter. The torque converter bolt could be found just in front of the transmission pan which was similar to your experience however it was located in a flat area and not in the bell housing (I was ready to drill out the bell housing but the engineers seemed to make some much needed improvements in accessing the torque converter bolt/plug) the other difference was that my crank shaft bolt was a 27mm socket. After finding the bolt after turning the crank, Ioosened the 4mm Allen bolt but literally nothing came out but a few drizzles. Luckily it did have the distinctive smell of transmission fluid or I would have thought I opened different bolt. I changed the fluid when the vehicle was cold, and my question was should I have ran the vehicle to warm it to operating temperature in order for the torque convertor to yeild more fluid? I would think that being cold would be ideal.

[@LeighSr]

Thank you. The main reason for the trickle is because there is no air vent, also the the drain hole is too small, you might open the transmission’s plug to drain the ATF at the same time.

[@LeighSr]

I made a webpage for more details about change ATF, www.leighsr.com/atf-change-7229

[@markholland1578]

@@LeighSr Amazing what a resource it is. You were my inspiration to tackle my E550 as it has the new blue fluid and it has the A85 option (not sure what thay means but FCP said it was one of the lowest viscosity fluids and has a few special additives). I changed the transmission fluid regularly on my 97 C230 and my 2010 GL450 and used Valvolines MaxLife Full synthetic. I was able to get about 2-3 liters out of those torque converters (real slow drip as you mentioned but steady). The only thing I did differently was a tried to drain the converter first versus having the pan off when draining the older vehicles (the 97 has the 722.6 and the GL has the 722 9). Perhaps not removing the pan creates more of a vacuum (??).

Well done "go through video". That converter plug screw, is the same one I have on my 7g tronic+. You have to adjust the transmission housing to reach it. Unlike others I've seen on KZbin, thier converter screw plug comes straight off, I don't know why Mercedes did that.

[@vincentlonbird1806]

Also, salute to you sir for doing transmission service well dressed 😎

[@cesarbojorquez7418]

You are awesome! Thanks a lot

[@SUB-Entertainment]

Great video thanks. I have gle 350 but the torque converter drain is at an angle even with small drilling hard to reach so what I did instead I flushed using return transmission line which in my case is on the passenger side of the transmission. Just remove one screw and pull out the return line. After that I connected with a pipe drain in a graduated jug I used the empty ATF fluid 1 gallon as it already has the marking. I started the engine till I get 2 lit out and the pumped 2 lit in. Repeated the process till the fluid has same color as new. It took 13 lit to completely flush and fill to the over flow mark at 45 Celsius.. this video helped. So I think return fluid line of flush is better as every drop of fluid is flushed and no need for drilling also not just draining torque and transmission pan will not allow fluid in pipe , cooler and valve body to clear. Only flush through return line will remove every drop . Some might need more fluid based on how dirty the transmission is.. thank you

[@LeighSr]

Thank you and Flushing is ok, but I still recommend replacing the ATF filter and cleaning the oil pan. You can see there is too much sludge on the bottom of the oil pan in the video.

[@Xavier-pk3yx]

今天刚换完，换之前我还祈祷我的torque converter的放油螺丝不会在那么变态的角度，结果没办法我也和你一样钻了个洞。diy还真是要有创意，如果不是看了你的视频我是怎么也不会想到钻洞这个办法

[@LeighSr]

我就是一根筋，不达目的不罢休😄……钻眼之前我还试过锯短六角扳手，结果试了几次都不行，后来想即使拧下来，那么小的空间也拿不出来，还要上扭力扳手……折腾了一小时，最后一招就是钻开😄

[@Xavier-pk3yx]

Senior Leigh 我也是被那个螺丝折腾很久，主要是拧不开，把螺丝都给拧坏了。后来用heat gun加热了下螺丝才拧下来。也惊讶于torque converter里居然有那么多油，感觉一半的油都在torque converter里

[@LeighSr]

@@Xavier-pk3yx 奔驰的维修手册里说，里面有4升油。

[@guangfaxu2024]

用Home Depot喷药的水壶来注油，太有创意了！

就是个手动泵的作用，不想花100多块钱买专用的，其实作用一样。这个才10块钱。

[@guangfaxu2024]

我家里的手动抽油机应该也是可以的，用之前要好好清洁一遍。请问李大师，我没有专门的读码器，油温监测准备用红外测温枪对准油盘测温问题应该不大吧？大师的视频做的太精细了，作品数量上不去也是订阅量少的原因，总要有取舍，宁可作品少也不能降低质量。

[@zhuanzhuanjiao4349]

[@atoiler1389]

Senior Leigh. At 17:00 into your video you are pumping in the ATF fluid. I am curious if there is pressure building up in the transmission fluid chamber or did you do something to allow the air to come out as the fluid was pumped in?

[@LeighSr]

There is a vent valve on the top of the transmission case to balance the pressure. See the picture of the 722.9 on www.leighsr.com/722-9

[@luonghai1538]

Thank you very much and I would like to ask you 2 more questions 1. When drilling the torque converter area, can needle pieces get into the body and thus cause damage after the rubber cap is closed? 2. I can't actually buy a diagnostic machine to check the temperature. I read somewhere that when the outside temperature of the oil bottom case reaches 38 degrees, the oil temperature inside is about 45 degrees. So is it possible to do it that way?

[@LeighSr]

Sorry for the late reply! 1, Drilling is at the case part, not into the bell of the torque converter. So that won't damage the TC or AT; 2, Because of the accuracy of the IR thermometer, the result is unreliable. There is a diagnostic tool that can read the AT temperature: amzn.to/3QQWZ3O

Many thanks, great video. How long did it roughly take for the temperature to reach 45c?

[@FinTra_]

nice work. question: when you turned the engine to align the torque coverter screw, was the automatic transmission in neutral at that time? also , does your car have a eco stop/start feature because i did not see the removal of the auxilary pump ?

[@LeighSr]

Thank you and yes the first step was to move the A/T to N position, but that's is not necessary due to the TC is unlocked when the engine off. My 2013 W212 without an ECO Start/stop function, so no auxiliary pump remove. After 2014 w212 equipped the ECO start/stop, there is an auxiliary pump that has to be removed to reach the TC drain screw. I published the whole documents were pulled from MB WIS of change ATF for W212 on en.leighsr.com/mb-7g-atf-change-w212

[@JamesP-lp5do]

Great video and detail. I have an W222 (2015) S550 w 722.9. Will be doing this same service, although my converter access is on the lower side of the bell housing (i.e. about 5'oclock if looking at the converter). Question- I've seen different approaches on the refill. It appears you added all of the transmission fluid before starting the car and getting to 45' temp. I've seem some where folks add 6L, warm fluid to 45' then add another 3L, warm car again to 45' and then shift through gears and perform the leveling procedure. It seems the transmission can take all 9L in the beginning, and also appears this is the procedure per the WIS.

[@bradleytefft7747]

Senior Leigh, great video as always. May I ask a gew questions. Firstly, where did you get the part that screws into the atf drain pan that you used to put atf fluid in? Did the hdx sprayer come with the clear hose? Secondly, where can I get the items you used to plug into OBD II port as well as the diagnostic program? thirdly, did you buy all the ATF stuff as a kit or piece seperately? I will be doing my 14 E350 in 2100 miles so I want to be ready. I bought this car right after I started watching your videos and felt that I can do my own service thanks to you. You are a great asset to Mercedes Benz owners!!

[@LeighSr]

Thank you and I list the answers below: 1, For the MB 722.9 ATF filler adapter: amzn.to/3ge9lAt For the tubing, No, that is bought separate, it's regular 3/8" PVC tubing, you might buy it from Home Depot or Lowe's; 2, MB star SD connect C4, I bought it from here: @t, You might use an IR thermometer to test the temperature of the oil pan instead, but that's not accurate. I suggest every MB DIYer has a MB Diagnostics; 3, I used to purchase twice the material of ATF replacing, one is separating, one is kit. It's up to you. Just get them all if you buy separately. Yes, you can do it. Keep a Mercedes is not a high-cost thing. Again, I appreciate your compliment!

[@Chubbys]

Thank you for this

[@rottdogsparky]

Is there anyway to tell when the service was last completed? Will the MB Star tell you?

[@ryturria01]

Senior Leigh, excellent video. What is your opinion on using the flush device 7 lb/sqin pressure to extract all the rest of the ATF from the case? You would then add the full 9 liters. Is there risk with this method? Thank you.

[@LeighSr]

Thank you, and the best way to keep the transmission clean is to replace the oil filter and thoroughly clean the oil pan where collected most oil sludge. The transmission case is a relatively enclosed space, so the ATF won't oxidize like engine oil. That's why the ATF change interval is 4 or 7 years. To filling 10 liters to the transmission once, or twice (6 liters + 4 liters), WIS did not list the reason for 6 +4 liters and did not prohibit filling 10 liters once, so I filled it once and then drain out approx 1 liter to correct the ATF level. More detail on www.leighsr.com/atf-change-7229 and welcome discussion on the forum of leighsr.com

[@gcssat]

I remember reading and seeing other videos of this service of the W212 transmission fluid, but never as great as this one. I had a 2012 E350 Bluetec, but the transmission fluid had to be changed every 40k miles. I had the prepaid service at the time and not knowing how involved it was, I left it to the dealership. Now, if I still had my W212, I'd be comfortable and confident doing the service after watching your video. I know the bolts are single use, they're made of aluminum. Were the clips all the same size or did you have to remember the position of the clips around the pan when it came to installing with the new screws? I know you drilled an access hole, but when it came down to draining the torque converter, was the issue the wrong angle on the torx tool or is it a special tool that you need to buy? During the draining and leveling of the fluid, would it be a good idea to use the filler adapter with the clear plastic hose to better control the flow into the drain pan? I've always heard of the mityvac to fill the pan, but they are a lot more expensive. It was a really great idea to use a sprayer to pump the fluid, I would have never thought of that option. I have an idea for another video. When I had the transmission fluid done, I also had the differential fluid changed. I know there isnt any mention of this in the service manual, but I figured to do the power train from start to finish! Awesome to be able to see all these great videos!

[@LeighSr]

If the model year of your E350 is 2012, the ATF change interval is 70k miles or 7 years. more detail might visit en.leighsr.com/mb-7g-atf-change-w212. For the clips, there are 5 same and 1 different, the special one is at the corner to fix the cable located at the front right. That's pretty easy to identify. For the drilling access hole, that must be a design defect, offset hole. I tried to cut short an L key to access, but the room is to tight, I can't take the screw out, even I can loose the screw. I researched the whole of the MB booklet, no special tool for that. That won't happen with my S550. To manage the drain flow, that's difficult. Because the oil will drain immediately when you remove the drain plug. Only collect it with a big pan. The filler adapter only can use on filling. The differential fluid is lifetime using, no necessary to change, except G class. Thanks again for your compliment!

[@WesMcCawley]

Hi Sir. This is the best video ever made in my opinion. Very professional. I have a question? So, you don't recommend ever changing front or rear diff fluid? What about transfer case. Bought a 2012 E350 and want doesnt look like anything as far as transmission fluid, diff fluid or transfer case has been done per the Carfax. Thanks for any information you can provide.@@LeighSr

[@jessechen2701]

Interesting the torque converter drain was not accessible through the hole without drilling. I've actually done transmission fluid change in my old W201. The difference I notice is that your wheels are hanging loose (suspension unsprung) and I had wheels down (on ramps in front). I wonder if wheels are holding up vehicle maybe torque converter screw is accessible without drilling a hole? Thoughts???

[@pmo3448]

Great video! I have one question: If you have not changed fluid in around 100,000 miles, and the fluid is very black, should you still drain the torque converter? Or should you only change the fluid in the transmission pan?

[@LeighSr]

Thanks and the TC contains 30% ATF, the best way is replace it especially with long range. The WIS of MB suggest interval of replacing the ATF every 60k miles or 6 years.

@@LeighSr Thank you!

[@waqasazmat81]

why are you letting the fluid drain during the fill process? how do you know the correct level of it? Thanks for posting the video!

Hi Senior Leigh, do you know if it is necessary to shift the car into neutral before starting this service? I looked at the WIS document and it says to do that, but I have also read on forums that someone experienced a drained battery after leaving it in neutral since the car's electronics were still on. Thank you!

[@LeighSr]

Actually I don’t understand why the WIS write like that. When we switch off the engine, and open the door the A/T will automatically switch to Park. Only turn the key to the 2nd position, we can switch to neutral again. And yes at the 2nd position, all of the electronics will running, if the battery is not health enough, that would be drained out. So I don’t recommend do like that.

Hi Senior Leigh, it's a great easy to understand step-by-step video. Thanks for sharing. And a question for you if you don 't mind? When the pan is bolted back up, and the initial 9 litres have been pumped into the trans,. At this point you start the engine and shift through "R" "P" and "D", repeatedly, with the engine running all the time. Then when the temp reaches 45c, check if there is fluid running back down the input pipe. If not, you pump a little bit more in, then wait until it start's to run back down the pipe. ( all the time at 45c) When it slows to a trickle, remove the input pipe, and replace the drain stud, And all this time, you will have the engine running? Thanks again, Jim.

[@LeighSr]

Thank you, and yes, the engine must be running when you checking and correct the level of ATF. I have published a video regarding checking the ATF level of 722.9. kzbin.info/www/bejne/nnachKZuedh0Zq8

Dear sir, you have made a beautiful video, so clear, so clear. Is it possible to make the same video for transmission 725.0 as well? Already bednakt!

[@LeighSr]

Thank you, and I do not have the transmission 725.0, but I may pull out the original documents of replacing 725.0 ATF from WIS, and post them on leighsr.com I'll let you know once I finishing the post. Or you might subscribe to leighsr.com, in order to receive the news from there.

This is an amazing video. Looks like watching a film. I have a 2013 Mercedes E400 Hybrid, which is also a W212. Will this process, particularly drilling the hole to access the torque converter's drain bolt, still applies ?

[@LeighSr]

Thank you 🙏, and due to same chassis and year, that’d quite possibly, but I'm not sure. If the drain plug of the torque converter bell is aligned with the access hole, that’s very good, otherwise you have to drill a hole.
