Great video, I watched it just for entertaining purposes! The information offered is priceless and the fact that you explain it for the normal DYI’ers adds even more value to it. Keep up the great work!
Thanks! If you haven't seen it, you might find my "Black Death" video interesting, as it was made in a similar style... czcams.com/video/HV0XCpN76cg/video.html
By far the best video explaining this, because you're not just saying do this and do that, you're showing us novices what we need to look out for that experienced people just take for granted! Superb!!
Wow! Thanks very much for the great feedback Louis, I really appreciate it! 😀
UPDATE - Technically, you should carry out the final fluid check and drain off any excess fluid with the engine running (not stopped as shown in the video). Thanks to John Yun and others that raised this point! AMOUNT OF OIL THAT CAN BE DRAINED & REFILLED - The transmission that features in this video doesn't have a drain plug in the torque converter. Hence, the amount of fluid that can be replaced is less. If your car doesn't have a torque converter drain plug, it is possible to drain more fluid by disconnecting the fluid lines that run to the oil cooler but I don't do this, as it isn't the standard procedure and hence, it isn't in the video. The transmission in my car is at 105k miles, still runs as new and I have always serviced it as shown in this video. However, some other Mercedes cars do have the drain plug and if you have the option, you should drain it, as it allows you to replenish more of the fluid (more effective fluid change). You might have to turn the engine (in normal direction of rotation) by turning the crankshaft pulley with a large socket / bar (if unsure how, make sure you have read up on how to do this before attempting!). Hope this helps! Thanks, RMR
if for instance my gearbox do have a torque converter drain plug an i drain oil from it as well, should i just refill oil through main gearbox oil drain plug or fill some oil seperatelly in to the torque converter too?
@@1945Aleksandr Hi, Yes, you put the torque converter plug back in. Then fill the gearbox as normal through the drain plug. When you start the car and step the box through the various positions (as shown in the video - P, D, N etc), it will fill the torque converter. You will then be able to go back under the car and top up the fluid level. Hope that makes sense! Thanks, Phil
The engine might heat up faster if you rev it around 2-3k rpms like when you warm it up for the smog checks. (10 minutes for full heat of cats and engine)
@@eschrader That's a good point! I was lazy and went in the house for a coffee! lol! Cheers, Phil
@@eschrader WIS procedure recommends letting the engine run at idle speed.
Explanations are the clearest they can be, we see everything very well. Thanks a lot for your videos! :)
Thanks for your kind comments! :-)
Great video and detail. I hate it when people showing DIY skip crucial steps! Thanks for the step by step process
Hi, I really appreciate your comment! I try really hard to make my videos show every step so that you can do the job yourself by watching just the one video! 😊
Ex mechanic but still bamboozled how to do this job until I came across this vid. You will not find a more clearer or clever method than this from a DIY point of view - Excellent!
That's very high praise, thank you very much! 🙏
Amazing. I just change transmission fluid and filter myself after watching this video. Exactly how he instructed. So so easy with no problem at all. Big thank you as I saved £350 labour easily.
Thanks so much for the kind comment! Well done with the work, always really happy when one of my videos helps someone save some money 😁 cheers, Phil
Thank you so much for this. I did my car yesterday following your instructions. I used a magnetic spirit level on the underside of the sump, was able to dislodge the pipe inside with a screwdriver to get most of the fluid out before removing the sump pan. I used a small oil pump I had bought from Lidl and the pipe fitting you recommended. A very satisfying experience, which I wouldn't have been able to do without your excellent video.
Wow, thank you so much for your feedback and for the extra info about the Lidl pump. I have heard about people using these, I think I might need to get one for next time I do the job! Cheers, Phil
@@ReviveMyRide You are very welcome Phil and by pure coincide, the fatter of the two pipes on my pump was exactly the right size for the M12 x 1.5 fitting!

Great video, well done in terms of detail and step, very clear and concise explanation. Glad to have found this video, I'll surely do my own trans after having to pay almost double than what it used to be. The fill kit setup you presented is well made and easy to acquire.
Thanks for your comment! 👍😎 Yes, it's a little time consuming but as you say, the service is becoming more expensive, so if you've got the time, worth giving it a go! Thanks, Phil
One of the best DIY vid; very very informative with details and cost saving techniques. I subscribed because I would like to see more of your vids on Mercedes 722.9 as well as on my corvette race car
Thank you very much for taking the time to comment and for your kind feedback! I still have my Mercedes that has the 722.9 transmission in it, so I'm sure more videos will follow! If your vehicle, happens to have a Mercedes diesel engine in it, then you will find quite a few videos on this on my homepage too. Corvette race car sounds fantastic, I take it you are into your motorsport? I don't have one of those yet but a Corvette is on my Car "Bucket List"! Thanks, Phil
Great video. Thank you. Doing my service this coming week.

Merci Philippe, content que la vidéo te plaise !
Getting ready to do this job on my 722.9 on my slk 55. Thanks for your video.
Great stuff, hope it goes well! Give me a shout if you have any questions and I'll try to help if I can! Thanks, Phil
Great video. This whole "fill and check through the drain" had me wondering what the heck was going on. Your video makes it understandable and easy to do.
Changing the engine oil was already a huge mess. LOL
So I wanted to check on how to do the transmission properly.
About the ones without a torque converter drain plug, I'm sure you could do with this, what I do with GM cars, where you just fill it, run it a bit, then drain it again, then refill it, to replace more fluid. Definitely a little more costly, but you do get more old fluid out.
I watched another video before this one. It pointed out that when you drain the fluid, you can push that white plastic level piece up into the pan, to allow it to drain more, before dropping the pan.
After watching this, now I have a better idea of how to make a took for filling it. Thank you.
Hi, great that the video helped with your tranny fluid change! Good point about flushing out with some fresh oil and redraining. Definitely an option for those concerned about getting a full fluid change. Yep, you are right, it is possible to push up the fill tube and drain more fluid before dropping the pan, making it less messy! I think I would do it this way in the future... Thanks for your comments and sharing your experience! Cheers, Phil
Thanks. Helped me to change the transmission oil on my C350. Much appreciated and very well explained.
Thanks for taking the time to comment! Really happy the vid helped you DIY the job and save some money!
Very helpful!! I will do my as instructed.
Very nice invention of the refill pump ! Thanks for sharing.
No probs, hope it helps! BTW, a few buyers have mentioned using an inexpensive electric pump that they bought from Aldi for this job (probably available elsewhere - Amazon, Ebay etc). Not sure of the details of it but might be a good alternative. Although, I must say, I find the hand suction pump really useful for all sorts of jobs since I got it, so it is a good addition to the garage. Also, you would probably still need an adaptor of some kind into the sump outlet. Thanks, Phil
Perfect tutoring , explained very clearly and concisely , I know understand what is involved , as I was quoted £450.00 for the gearbox service. I will buy the parts And ask my mechanic to replace them. Look forward to your next videos.
Thanks for the kind comment and for taking the time to post it! Glad the video helped you :-)
What a wicked video, so much detailed information, well done‼️
Thanks so much!! 😁😁
Brilliant.. so happy i found this .....

@@bigbruno56 hi, I believe the part you are talking about is the overflow pipe that fits just inside the drain plug (I think I call it a snorkel in the video, didn’t know the correct term for it at the time!). Anyway, it is really important but if you are filling the transmission from the bottom and then doing the level check, it is the overflow pipe that allows you to set the level correctly. Effectively, you fill from the bottom, warm up the transmission, remove the drain plug and any fluid that is above the level of the overflow pipe will run back out. There’s a good write up about it here: www.youcanic.com/wiki/mercedes-7229-7-speed-transmission-check-fluid-level If you want to remove the overflow pipe, my understanding is that there is a special tool / drift that allows you to do so. I’ve never done it this way, but here’s a link to the info. mbworld.org/forums/attachments/e-class-w212/417964d1537904979-service-207-coupe-212-sedan-automatic-transmission-oil-pan.pdf Hope that helps! Thanks, Phil
@@bigbruno56 Hi, to be honest I've never done it this way. My gut feel is that it isn't a good idea because the snorkel is a plastic piece and therefore, is quite light, so I imagine it would float around inside and maybe get caught up in something? I know it seems like a pain but if you buy the pan gasket and new bolts, you can go ahead and drop the pan and this would definitely be the safer option. Thanks, Phil
@@bigbruno56 No probs! Hope you get on ok with the job!
@@bigbruno56 Hi, if you were planning on doing a full transmission fluid change, the minimum amount you would normally change is 5L (for cars like mine that didn't have a torque converter drain plug). If you are able to completely change the fluid, then it can be up to around 7L. So, two comments really. 1) Hardly any fluid has been changed, so the work that you have had done isn't a full fluid change / service 2) I don't want to alarm you because I have zero experience of using slip stop in transmissions but I would never, ever use anything but the recommended fluid in my Mercedes transmission. They are pretty much bullet proof if serviced correctly with the right fluid and filters etc. You didn't mention in your previous messages that your transmission wasn't working properly? Were you having problems with it, hence the slip stop? BTW, Mercedes transmissions can give the feeling that they are slipping (engine revs and the drive doesn't engage fully) if the fluid is low. Hope this helps! Thanks, Phil
@@bigbruno56 okey dokey, sounds like you know what you’re doing! 👍 and sometimes it is a case of keeping these old cars running. CZcams is very international, nice to have a viewer from Scotland, I’m in Yorkshire but you may have gathered that from the accent! 😁 cheers, Phil
Recently I've been considering an SLK with a 7 speed auto box, I'm guessing this guide may be useful. Thanks Phil
Yes, I think so. Depending on which model year you buy, the gearbox will be the same or very similar!
Very well explained. Thank you.

I found your video extremely helpful however instead of a hand pump I simply drilled a hole in the top of the new fluid container fitted it with a half inch poly tube drilled another smaller hole and use my air compressor to pressurize the container it worked great
Sounds like an interesting idea! I like a bit of improvisation :-)
Great video, well done and thanks.

@@ReviveMyRide what about the fluid left in the torque converter? How should I remove it?
@@cesarburbano816 Good question! I will give you my opinion but this is something of a hot topic at times on Merc forums! You may have seen comments on this video or in other places about the torque converter. In summary: Some cars have a torque converter that can be easily drained (On some, there is a plastic cover on the bell housing and then behind that a plug to drain the torque converter). If yours does have the means to drain the torque converter then you should do it, as it mans you will replacing more of the fluid with new during the servicing. Alternatively, I have seen some information about disconnecting the hoses that run to the transmission oil cooler, as this also allows you to drain more fluid. Sorry, potentially more research for you to do to see what is best for your car! If it makes you feel any better, if you think about what your are trying to achieve, which is longevity and smooth running of the gearbox - I have never drained the torque converter on my particular car as part of the gearbox oil change, I have had the car most of its life and it is now on 110k miles. Gearbox still works like the day it was built! Hope this helps!
Thank you so much Phill.
Glad you found the video helpful and thanks for taking the time to comment! Cheers, Phil

De rien ! je viens de réaliser mon kit grâce à toi , il se visse en lieu et place du trou de vidange du carter de boite sur ma Mercedes classe E 280 CDI, un petit robinet, un tuyau, relié à une boite tube qui s'ouvre par le haut vissé avec joint (tube PVC 100) sur le couvercle également une valve de roue, un tuyau intérieur qui sort a l'extérieur vers le robinet et boite, pour faire monter l'huile installé dans le tube (1l ) je branche le compresseur sur la valve avec un manomètre et il me reste à appuyer sur le manomètre et l'air comprime la boite et fait sortir l'huile en pression et le robinet comme pour toi me permet de couper afin d'éviter que l'huile ressorte lors du remplissage de ma boite. Pour info utilise un tuyau PVC plomberie de 100 également pour boucher un raccord PVC avec couvercle et joint qui se dévisse, et à l'autre extrémité un bouchon aussi en PVC de 100. Encore merci pour ta vidéo, Amicalement Philippe

Thanks for your comment! 😀👍
nice sharing my friend.. watching from Malaysia
Thank you! Nice to have a viewer from Malaysia! 😀👍
Thanks for taking the time to do these. I'm looking into a Metris van which uses the 7Gtronic plus. Did you not need to drain the torque converter? It has a drain plug as well. Probably only a few ounces so not that big a deal.
Hi Stuart, thanks for your post! Just had a look at Metris vans on google as I hadn't looked at them before, looks really nice! All of the variants of the 7G-tronic gearboxes are really good, so I'm sure you will like it! Yes, you are right, if your torque converter has a drain plug then you should use it, as you will get a better fluid change. Mine didn't have one, as it is an early model and the torque converter drain plug was added later. You may already be aware of this but just in case: The fluid type changed for the 7G-tronic plus (to 236.15 "blue" fluid) and the service intervals got longer. Thanks, Phil
Good one there
cheers! 🙏
Good work go ahead
Thanks! 😊
I like this video of yours very much, it explains the technique of how to change the gearbox oil and filter very well.
However i think you should also mention to people that unless you also drain the oil in the torque converter as well, you are only
really doing half of an oil change as the torque converter holds about 4 litres on its own, so you are only mixing old oil with new oil ?
Hi Alan, glad you liked the video and thanks for the comment! You are correct about the torque converter. Early cars like mine don't have a drain plug but a lot of the later models did. I provided an update to cover this in a comment that I have pinned and in the description. Unfortunately, I can't easily add anything new to the video... Cheers, Phil
Very helpful
Thanks!
Thanks
Very good video on the procedure but most helpful was the re-fill apparatus and your description on how to make it. Question is what did Andy Horsfal make and do we need to get one make also OR is everything in your diagram all we need to buy and assemble to re-fill the transmission? Thanks again for a great video.
Hi, thanks for your message & sorry for any confusion. If you buy all of the things that I described in the kit, then that should allow you to refill the gearbox. Andy made me an adaptor on the lathe that screws into the gearbox pan (sump plug hole) but you can buy them and it appears in the kit (similar to item no. 1). He just wanted to practice his machining skills and I promised him a mention if he made the part for me!
@@ReviveMyRide I thought that might be the case but just wanted to be sure. Thanks again.
yes very useful. thanks
Thanks for your comment! 🙂
Your video is very well made including real good audio. It is very different from other DIY video. Thank you. Just wandering if it work for B200 CDI 2012, Model W246?
Hi, thanks, really appreciate your comment! :-) I did a bit of research and it looks like your car has a very different gearbox fitted to the one that features in this video. You will want to double check but it looks like your gearbox is the CVT 722.8 gearbox. I think my video will be good for "principles" of a gearbox fluid change but there will be a lot of details that are different. For example, it looks like you can fill your gearbox from the top, you can get a dipstick for your gearbox so that you can do the level check, of course it uses a different fluid etc. There will be other variables too. I did find some videos on CZcams for your gearbox, so if you search specifically for your gearbox type, you will hopefully find some more information specifically for your transmission. Hope this helps!
Thank you, I suspect W246 automatic transmission is different from
w245 (which is the CVT 722.8 you mentioned). I am not sure. If you have infor, please help us owners of Diesel W246 (not W245) make a video. Cheers
Will try mine
Sounds good! thanks for your comment! Good to hear when someone decides to give it a go. I found it a little time consuming but not that difficult... 👍
Clever!
Thanks! 😀👍
All very good movies!
🙏 Thank You!
Very nice super.
Cheers! If you're a glutton for punishment, I have an updated video out on the same subject, which is being well received by the Mercedes community... czcams.com/video/tda4zokL4Os/video.html
Great information, i am planning to do the same for my c200 w205 2015 and only owning it for 2 months (so don't know much about Merc). this will be my first time doing this, so i am a bit nervous, but i am a DIY person, so i am planning to go ahead. Can i check with you what socket/size do you use for the 6 pan bolts please? Thanks very much
Hi, I'm pretty sure that it was an E11 torx socket. I'll link to a set here, so that you can see what I mean. amzn.to/3nPHauC BTW, I have done an updated video, which from comments etc, vieweres are saying is better, more information and clearer. It's here if you're interested: czcams.com/video/tda4zokL4Os/video.html
Love your videos keep them coming. Have you ever heard of a message error Pre safe functions limited. I got this message today on my 2014 E300 diesel hybrid ???? Please help. Thanks 👍👍
Hi, glad you like the vids and thanks for your comments! Regarding your query, this is the first time that I heard about this warning. I did some reading (imagine you have been doing some too!). Seems that the newer Mercedes car can "prepare for an accident" if you brake heavily or if certain sensors give feedback (or fail to). Found this interesting discussion on a well known forum, hope it helps! www.benzworld.org/threads/pre-safe-functions-currently-limited.2094274/
Hi m8 top video I have a 12v oil pump I got from lidl used it before down dip sticks on auto box's and engine oil do you think it would work on the merc box instead of the hand pump ps my ml320 has no dip so I would be doing same as you Alan
Hi Alan, Sorry for the slow reply. Yep, I have had a lot of comments in the past from people who prefer to fill through the sump plug using a small pump. So it should work! Might be easier / less messy if you have a small valve screwed into the sump outlet but not essential. Hope that helps! Cheers, RMR
great video; thanks. Did you also replace the plastic pipe (that connects to the drain hole) in the pan as well?
Hi, thanks for your comment, glad you liked the video! 👍 No, I didn't replace the plastic fill pipe. I have read a lot of write ups and I haven't come across anyone replacing theirs but some people probably do! Apparently, if you are just doing a fluid change (not dropping the pan and changing the internal filter), you can "pop it up", which allows more of the fluid to drain and then put it back to its original position again but I've never done this myself. Hope that helps! Thanks, Phil
I stumbled upon your video today again and I forgot to mention you need to keep the engine running while fixing the oil level. The oil should start dripping then you can close the plug. Other than that it was cool.
Thanks for your comment! As it happens, I stopped the car, checked it immediately (as shown in the video) and haven't had any problems... so I don't think it amkes a huge difference. It's a while ago now and I "think" I stopped the engine so that people could hear what I'm saying in the video? 😂 BUT Yes, you are 100% correct that technically, you should level check and top up with the engine running. Thanks, Phil
I think a running engine would make a difference in the fluid quantity. How much oil did it take to fill?
Great video, what is the size of steel pan bolts you used? Thanks
Hi, they were M6 x 40mm cap heads. TBH, for the job they are doing, they seem a bit long, you would get away with 30mm or 35mm long bolts. Just make sure you use Metric coarse (which are basic metric bolts) as the pitch of the thread is 1mm, which is what you need. Thanks, Phil
I saw another video where someone filled through the trans dip stick hole then cycled through the gears when idling. Do you only need to do some of that if you drain the torque converter?
Hi, my understanding is that the 7G-tronic transmission doesn't have a transmission level dipstick. Hence, the unusual filling and level checking process. The earlier 5G-tronic did have the facility to add a dipstick, so maybe in the video you mentioned, it was one of those? Regarding the torque converter, it fills automatically from the tranny sump when you start the car, then you just top up the level (through the drain plug). Hope that helps! Cheers, Phil
Thanks for the video! A totally noob question.. is this the same transmission model as used on the 7-speed auto for the SLKs R171? Thanks again :)
Yep, my understanding is that the SLK from that era used the 7G-Tronic gearbox. Very good box and very reliable is serviced regularly! Thanks, Phil
Hi.I ve got transmission oil cleaner (Liqui Moly).Shall I use it or it may make gear shift worse ? OM642 with 190 k miles and probably oil replaced about 70 k miles ago in MB Salisbury .Shall i replace oil from torque converter too ? Thanks.
Hi, I've never used a transmission cleaner. My concern would be getting it all out again so that it doesn't interfere with and degrade the new transmission oil. These tranny's are difficult to drain without a certain amount of extra disassembly. Personally, I would try a transmission fluid and internal filter change before resorting to a cleaning fluid. Yes, if it is possible to drain the torque converter, I would do it. Here is a video that shows how to do it. czcams.com/video/oLjx6kV8MEo/video.html Hope that helps! Cheers, Phil
You should put a tap or screwdriver up the drain plug to knock out the overflow “snorkel” to allow all the oi” to drain before removing the sump plate ....
@kfor6631 Thanks that's a good tip! In fact, I now do it that way. I have an updated video where I do a few things differently (now with more experience), It's here if you're interested: czcams.com/video/tda4zokL4Os/video.html Thanks, Phil
Do I have to refill oil from the bottom. How about refilling from deep stick on top of angine ? Thanks for tutorial
Hi, glad you liked the video and thanks for your comment! A lot of these cars don’t have a dipstick for checking the gearbox oil level and the only access point for draining and refilling is the drain plug. Hope that helps! Thanks, Phil
Amazing Stuff. Keep Working hard! Enjoy Your day =O
Thanks for taking the time to comment and glad you enjoyed the video! :-)
Great Video! by the way, how did you make the valve? thx
Hi, in the diagram at 14:12 in the video, you can see all of the equipment that you need for a filler set up, including a valve (Item no. 4 on diagram). They are all listed in the description. I used a different valve in my video because I just had it lying around but if you need to buy one, the one listed in the description will be cheaper for you. I had a friend make an adaptor that goes into the sump for me on a lathe at work but then later realised you can buy them really cheap (item no.1 on diagram). Hope that helps! If you have any other questions, just let me know! 👍
I also had another question you said you put 5 into the sump but the transmission calls for 9 and 1/2 quartz. I did drain the torque converter as well. should I put some fluid in the sump and run it for a brief period of time to fill the torque converter??? And then top off?
Hi, my model of the transmission doesn't have the torque converter drain plug and so I wasn't able to change as much of the fluid as you will. Yep, that is exactly what I would recommend: fill the sump to the level (when it starts to run back out of the level tube), run the transmission and step it through each of the gear positions, stopping for 5-10secs at each position (Park, drive, reverse etc), you will probably feel the drive engage, with your foot on the brake. Then check the level and do a top up. Of course, you will also have the running up to temperature and final level check to do too. Hope that helps, thanks!
What about removing the return line to the transmission pan so that you can flush out any transmission fluid left over in any trans coolers. Also what about the torque converter Is it possible to drain that as well? They usually have a cover which can be removed to reveal a drain bolt.
Hi, thanks for your comments! I didn't disconnect the return lines because that wasn't part of the procedure that I decided to follow. I suppose I was trying to keep it simple. I have heard of it being done, it just comes down to personal preference. Yes, you are correct, if your torque converter has a drain plug, then you should drain it as well. Please see a comment that I pinned to the top of the video comments board for more info! Thanks, Phil
Great content, thanks!
I have 2011 w212 E200 CGI with 5G-Tronic. You know if they have same Refilling adapter
M12x1.5 (male thread) and my transmission is also call 722.9?
Hi, Good question that got me checking around a bit! Looks like they offered two auto transmissions on your model of car. The 5 speed, known as the 722.6 and the 7 speed, known as the 722.9.
If your transmission is a 5-speed, then it is a 722.6 gearbox and the thread size for the adaptor is different, it is a M10x1.0 (male thread). Check out this website which may be useful to you. nemigaparts.com/cat_spares/epc/mercedes/1/ga/722646/21s/27/115/?chasis=212003D01 Also, maybe do some searches for a 722.6 transmission fluid change video as the procedure is likely to be slightly different. Sorry, I haven't worked on one of the 5 speeds before. Hope this helps! Cheers,
Phil
@@ReviveMyRide Thank you for your reply! Is helping alot. Keep up the good content sir. :)
What is your opinion on the FEBI parts and the FUCHS fluid? Is it good quality and sufficient enough?
Hi, Febi Bilstein is my favourite after market brand and I look for their products first when I’m searching. I’ve used them lots and always been happy with the quality. Fuchs Titan is my fluid of choice and I’ll always buy in preference if I can get it! I’ve used it in my Merc gearbox for the last couple of fluid changes and it’s worked flawlessly. So, I don’t think you’ll be disappointed with either of those brands. 👍 cheers, Phil
Is it possible to fill via the ATF dipstick rather than mess with that whole plumbing store set up? I have the dipstick from MB to measure the fluid level and a new filler cap w/red locking tab once I’ve finished. This would be less expensive and much easier although maybe a bit more time-consuming introducing the new fluid. Never seen it done this way though so wanted to ask first. Thanks in advance for any advice.
Hi, I was aware of the dipstick that you can buy but I'm pretty sure it isn't available as an option on all of the 722.9 transmission iterations. To answer your question: It should be possible to fill through the dipstick but you may be breaking new ground as I couldn't find any hits when I searched for it. I don't think it would be my preferred option as it presents a couple of problems: 1) As you say, filling would be slow. 2) You would fill down the tube and then need to use the same tube to do the level check, so fluid still in the tube may foul the dipstick. Since I was underneath the car anyway (to drop the pan and change the internal filter etc), I found it easy to fill through the bottom. If you do decide give it a try, please let me know how you get on! Thanks, RMR
I don't have the service information on my 2009 Mercedes-Benz S550 4matic. My oil pan has a leak. If I do a Transmission pan service will it damage my Transmission? I'm very worried about that......
Hi, if your pan is leaking, it is almost certainly the rubber pan / gasket seal. These transmissions are sensitive to fluid level, so if you are losing fluid, it needs to be sorted or you will start to get problems. If you have a little too much or too little fluid, it won’t damage your transmission but it will start affecting how it operates. I’ve actually created a much more detailed video now, give it a watch and you should hopefully gauge how confident you feel about doing the work diy. czcams.com/video/tda4zokL4Os/video.html Maybe get some quotes from local Mercedes Benz specialists and then you can make a decision on it. Hope that helps, thanks, Phil
Great job
Sir How much put oil in side 5 le...
Hi, Thanks for your comment! I'm not 100% sure what you are asking but I think you are asking how much fluid goes back into the gearbox? If so, I put 5L in initially, then I went through the warm up / priming sequence and then added more. The exact amount that you put back in will depend on the version of the gearbox that you have. for example if you are able to drain the torque converter. I hope this helps! Cheers, Phil
Do you know how to replace the hydraulic pump on the same gearbox.
Sorry, I haven't needed to do that before, so don't have any experience to share. I did find this video. It's a very LONG video but may help you! Thanks, Phil
Hi ,I have a e220 ,5years old,with 28000 on the clock.Do I need a auto transmission service.it seems a little early for that. Thank You
Hi, it seems that Mercedes have changed the recommendation a few times for this gearbox, so there are lots of answers out there including a service at 40k, 50k and even 75k miles. However, they all say "or at 5 years". So, strictly speaking the transmission service is due according to age, if not yet due to mileage. Personally, I would be tempted to wait another year but that is down to personal choice. There is a good resource here that might help you decide lite.servicemercedes.co.uk/ess/pc/ Hope that helps!
Daft question, is there no filler plug or is it just in a hard to reach place?
There isn't a filler plug. I know it seems a bit weird but I have come across this before on a VW Golf DSG autobox too, so I think it must be fairly common.,
Great video but I am totally confused by your comment "From mid-2010 onwards a 7G Tronic plus auto transmission was fitted and this one used blue transmission fluid. NOT FEATURED IN THIS VIDEO."
I cant find anything on this type fluid can you please advise!
Hi Joe, Mercedes continued to develop the 7g-Tronic (722.9) transmission throughout its service life. From 2011 onwards with the introduction for Stop / Start technology, they changed the fluid type. If your car is pre 2011 / non start stop then there is some guidance on fluid in my video description. Post 2011 car or just interested, here's a link to a discussion on a forum: forums.mercedesclub.org.uk/index.php?threads/722-9-transmission-fluid-change-questions.183783/page-2 Hope that helps! Thanks, Phil
What you think about mercedes saying no need to change the transmission oil it's last life of the vehicle. Good video
Hi, As far as I know, they all need to be serviced! The gearbox that features in this video is the 7G-tronic (722.9) and should be serviced every 40,000 miles. Later gearboxes referred to as the 7G+ from circa 2011 onwards have a longer service interval of 70,000 miles. Hope this helps, you can find lots of info on the forums of mbclub.co.uk or mercedesclub.org.uk
On my GMC Sierra, the procedure is the same except the final level is established with the engine running,
Including filling the transmission through the drain plug? I thought this was really weird but maybe not if other manufacturers do the same... Yeah, technically, I should have left the car running. I stopped the engine and checked the fluid level straight away but as you say, ideally, should have eft it running (I shut it off so that people could hear me speak but should have done a voice over during editing instead!).
Hi there, if the oil drains out as soon as you take the sump plug off, does that mean it was overfilled in the first place as the level is above the snorkel/overflow pipe?
Hi, no, not necessarily. The final fluid check and level adjustment on the transmission is often done with it running, meaning some of the fluid will be in circulation. When draining the transmission, it is usually switched off and been sitting for a while. Just an estimate but I would expect up to 200 - 300ml to come out of the drain plug when you take the sump plug out. Hope that helps! Happy to answer any question you have if I can! Cheers, Phil
@@ReviveMyRide thanks!
Hi great video thank you! You put in 5 litres of ATF, but everywhere I’ve read about this states its 9 litres? Can you please explain this as I have a 7 speed as well?
Hi Graham, the most I have seen stated as a total refill volume is just over 7L, never as high as 9L, so I would say that 9L is definitely incorrect. The reason you see variation on the 722.9 transmission from around 5L refill to as high as 7.5L is because the transmission design evolved over time. It always had the same max fluid capacity but Mercedes improved the ability to drain it down over time. On later versions a plug was added to the torque converter, so you could drain it as well. Some owners also detach the pipes that go to the transmission oil cooler, so that they can change more of the fluid. If you check out this link, some members of the Merc forum have attached links to various documents (including how to drain the torque converter if the transmission in your car has a drain plug on it). mbworld.org/forums/clk-class-w209/471925-wis-doc-722-9-torque-converter-transmission-drain.html Hope that helps! Thanks, Phil
@@ReviveMyRide thanks heaps Phil for the info, my Merc is a 2013 E400 sedan can I assume it has the 722.9 trans in it?
@@grahamsmith7407 no probs! yep, my understanding is the the 7 speed (7G tronic) is the 722.9. Then it moved to a 9 speed (725.0) and the predecessor was the 5 speed (722.6) Cheers, Phil
@@ReviveMyRide cool thanks again Phil!👍
you forgot to drain the torq converter. You should always drain it on 7g transmissions. you have to take down the extra oil pump and turn the engine until you find the drain plug on the torq converter. 10nm is the torq on the bolts :) Engine should be at running temp befor draining it :)
Hi, thank you for your comment, just to reply to your points: Early 722.9 7g's didn't have torque converter drain plugs. I previously added a comment on this video and made it a "sticky" where I clarified this point. Also, you can read about it here on the Benz forum, you will get lots of hits if you search for it: www.benzworld.org/threads/cant-find-722-9-torque-converter-drain-plug.2118665/ Some owners detach the pipes to the oil cooler to drain more fluid but I couldn't find an official procedure for this, so I stuck to the standard fluid change process. I used 8Nm for my pan bolts as this is the number I found in my documentation. It could be that it has been updated (procedures, fill levels etc do get updated from time to time by MB) but rest assured that 8Nm worked for me with no leaks. I think running up to temperature before draining may be a personal choice, there are plenty of other people who advocate leaving the car to sit overnight and then draining it when it is flat cold. I don't think there is a right or wrong way, or if there is it will probably make minimal difference, as the fluid is pretty thin and drains very readily. Thanks, Phil
Have you included a note that I’ve missed re; stepping through the transmission P-D-R to circulate the fresh fluid?
I saw a reference to it as being in the video but didn’t see.
My model is 2014 W212/3 E300 Hybrid
Hi, I have limited connection at the mo, so can’t easily go back and watch the vid but you are correct, after changing the fluid, it is a good idea to start the car, keep your foot on the brake and then step it though the various gears circa 10 secs in each one. Your car may have the 9G-tronic at that age? If so, the service is likely to be slightly different to what I showed. I have a 9G now but haven’t had to service it yet…. Thanks, Phil
Thanks Phil, for interest my car was assembled here in Thailand so is somewhat out of step with European/US models and has 7G transmission. Designated E300 blutec hybrid AMG Dynamic however it doesn’t use Blue 🤔
Enough of my ramblings, many thanks for your down to earth approach to vehicle maintenance and improvisation of easily obtainable items to save buying service tools that usually cost the earth.
@@barnstormin That’s really interesting about your car, I had no idea you could get a “hybrid” spec like that in other countries! Thanks very much, always trying to find ways for home diy’ers to get the job done to a good standard in a budget! 👍
Hi Phil,
Just out of interest, when I finally got around opening my MB EPC WIS/ASRA (which I should have done earlier) and started reviewing all the stuff I have clearly forgotten I note that the 7 G-Tronic on my car is actually 724.208 unique to Hybrids I'm assuming and the EPC makes ordering spares easier. There doesn't appear to be any difference in the hybrid ATF & Filter method and the only references to Hybrid is basically, 'Don't mess with any orange bits! Which I steer well clear of anyhow but if you or readers have any specific comments on Hybrid transmissions I'd like to hear them in particular references the torque converter drain which, until I get under and see if there's anything in the configuration that prevents draining as in non Hybrids, I need to research further.
Do you put any cain of glue to the pan gasket , because when I change my transmission oil I have a lot licking oil and I look you video and I don't see any glue putting on you pan gasket o what exactly I doing wrong?
Hi, No, you don't use any glue. If you did, then it might lead to the gasket leaking. So, you need to do the opposite, make sure the edge of the pan is really clean, with no oil residue, as this will help the gasket stay in place. Also, if the new gasket was folded up in a packet, then it sometimes takes a bit of work to straighten it out etc. The new gasket should have some rubber location lugs on it that fit into holes on the pan. These also help keep it in place, I mention / show them at 7:34 in the video. Hope that helps and good luck with it! Cheers, Phil
@@ReviveMyRide sadly I did it and when I was trying to put the last bolt it broke out on my and a lot of oil came out , and now I ordered new bolts , and a new pan gasket again and a they sooner I get those parts , I gonna fix it but now a don't now how to take off that glue whitout harmed the trasmission , I used the optimum black high flex gasket maker, and I'm very thankful for you help, I really. really appreciate it!!!
@@saulpaz8857 Happy to help! You can remove the old sealant from both surfaces using a green scouring pad amzn.to/3bxDyJm and some brake cleaner. It is time consuming but this wont damage the surface of the bottom of the gearbox or the pan. Take your time and take care to make sure old sealant etc doesn't get into the gearbox. You can also use a plastic implement of some kind (like plastic trim removal tools) to scrape the surface. Don't use metal tools because if you damage the surface, the new gasket won't seal properly. Were you using a torque wrench to put in the pan bolts? If not, then you really should, helps to prevent bolt breakage. Hope this helps and please let me know how you get on! Cheers, Phil

I have a 2007 E350 Sport W211 with a 722.9 7 speed transmission. I've serviced everything on the car myself except the transmission which I had the Mercedes Dealership do a year ago. I can't seem to find the dealer port for the trans in the engine bay so i can check the level or the color. Please Help!
Hi, one of the limitations of this transmission design is that most of the versions (if not all, I haven't checked every version) don't have a dipstick or any other means of checking the fluid level and colour from the engine bay. Mine certainly doesn't. You set the level when refilling it (from underneath) after a service and then don't check again until the next service. I'm not entirely comfortable with this either but it seems that is the modern way! Hope that helps! Thanks, Phil
@@ReviveMyRide Thanks!
for yournoil pan shape up to 18.6.2010 white overflow pipe should be used.
Thanks! The overflow pipe in my oil pan is white, it has just become a little discoloured over time and maybe looked a little yellowy in the video. Usually, if you just leave in place whatever overflow pipe is already there, then you won't go far wrong (although I hear Mercedes do update them sometimes).
@@ReviveMyRide what wis says is it should be replaced with white. That means whatever color it was up to 18.6.2010 it should now be white.
I finally did it. New bolts snap off, not even close to the torque spec. Huge mess in the driveway. I guess I will have to use the old bolts.
I'm with you on this one! I don't know why they use such weak bolts and the torque spec is really low. I'm sure I had at least one of the new ones break but thought maybe I had a bad bolt or two, otherwise I would have mentioned it in the video!
I cannot do the level, all the fluid is coming out . Can I cask you why? Thank you
Hi, I assume you are filling the transmission from the bottom using an attachment and a pump? The main reason I can think of that fluid would run straight back out is if the overflow pipe isn't fitted correctly. It fits directly above the drain plug and is like a little tube. As it is a few inches long, fluid should not flow back out of the transmission pan until the level is high enough to go above the top of the over flow pipe. Just for clarity, here is the piece I am talking about www.ebay.co.uk/itm/173929467890 and you can see it fitted on the inside of the transmission at 05:55 in the video. Hope that helps! If you have more questions, just let me know and I'll help if I can! Thanks, Phil
@@ReviveMyRide Thank you, I gonna have to drain the fluid and put it back in . Can I also ask you one last question please, Why does the car goes in limp mode when I reach around 100mph and until I stop the engine and start it again, It has no power and the engine doesn't go about 3000rpm even if I drive with 30mph.(I have an S320 2006) Also I want to mention that when is hot it starts then dies right away, always starts from the second try. Thank you ! Have a nice day!
small comment it is 4 nm + 180* dergees, for oil pan holder screws.
correction: main plug is 22 nm
What year and model car is that?
Hi, thanks for your comment! I have seen that 4nm + 180deg is the recommendation but many people don't have a torque wrench that does that low and / or an angle gauge for the 180deg turn. 8Nm worked well for me, no leaks and no snapped bolts. Agree, the main plug is 22Nm, it does come up on the screen in the video in yellow letter when I am tightening it up. Thanks!
@@ReviveMyRide the issue is not the bolts but the gasket used for it. 4nm+180 is just right not to appy to much pressure on it and overtime causing leaks. As per the bolts holding the pan those are alu and need to ve replaced. This is for those people doing this, so they have the info.
for low torque yoy can use a bicycle torque wrench or a digital torque adapter.
@@FinTra_ yep, exactly!!!
The fancy pan bolts are designed to be one time use only just like the gasket else they'll brake off like in a video from FCP Euro.

Hi, the part number is: N 007603 012102. I usually buy from Autodoc, but they have had some problems delivering to the UK since Brexit (might be resolved now?).

Best video out there for diy guys. 1 question. Im gonna buy a w213 2017/2018 E class estate 220d. Its got the 9g tronic gearbox right? Is the steps the same for the 9 speed as in the 7 speed one?
Also, whats your opinion on guys putting a new overflow pipe, new oil pan bolts etc?
Hi, pretty sure your car will have the 9 gtronic but if any doubt, keep an eye on your centre dashboard when driving on the motorway usually there will be a number showing what gear you are in. If it says 8 or 9 when cruising at speed, that will confirm it. I just bought a w205 with the 9 gtronic, service intervals are every 5yrs or 77,500 miles, whichever is sooner. I would think that the service procedure will be similar but I will get into it soon in my vehicle and will definitely do a video! Thanks, Phil

@@AB-dr8wq whoops, just realised I didn't answer all of your questions! Overflow pipe: I don't replace mine and have never had a problem but it comes down to personal choice.

I thought it was a bit excessive to replace them, so decided to experiment and two of the old bolts sheared when I started putting the pan back on, even using a torque wrench set to the correct torque. They were Aluminium on the 7 Gtronic gearbox, so presumably they get effected by the heat or work hardening or something like that. Thanks, Phil
Hi what’s different between 236.14 136.15 fluid?
Hi, I never looked into it in too much detail. I knew my car needed the 236.14 and left it at that. Apparently from 2010, when Merc introduced the Stop / Start technology, they moved to the lower viscosity 236.15. If your car is in the 2010/2011 age range and you're not sure what fluid to use, you are best to call Merc with your VIN and query it. Hope that helps some... Thanks, Phil
Revive My Ride thank you Phil I think exactly is what you said
Why can 't you put transmission fluid down to the dipstick?
Hi @caesar2064 Most (if not all) 7G Tronic (722.9) transmissions don't have a dipstick! Thanks, Phil
I think its worth dislodging the “snorkel” with a screwdriver to release more oil before dropping the sump
Thanks for your comment! Yep, agree, next time I do the job, I will do this as it makes the sump easier to lower without spilling oil. cheers!
How many miles before you change gearbox oil cheers.
Hi Steven, the service interval is 40,000 miles for the 7-Gtronic gearbox. From 2010 onwards (some people call this the 7G+), it moved up to every 70,000 miles. Hope that helps! Thanks, Phil
How many miles or time between filter and change
Hi, this has been updated a few times by Mercedes and so, as you can imagine, people have slightly different opinions! My view: If your car is manufactured up to 2010, it has the "red fluid" 7G-tronic (as featured in this video), the service schedule is 38,000 miles or 5 years. If you have the later 7G-tronic made from 2010 onwards "Blue fluid", it is every 70,000 miles or 5 years. Hope that helps! Cheers, RMR
