Well done that man , he deserves a pint
Thank you
Video is much better than MB Workshop Information System steps .
Thank you so much I hope many people can take advance if it
I really like your videos. Keep them coming!
Thank you so much for your comment. I definitely will.
Nice job. You have a talent for these videos and teaching these services.
Thank you so much for your comment.
Thank you so much for making this this video. Very detailed and great video coverage! Much appreciated, as making a video makes the whole job much longer..thank you! 😊
Thank you so much for your comment. I am working on another video as I’m writing this. Make sure you see all my videos.
If you do a regular change of the transmission oil there is no reason to change the oil out of torque converter.or even do a flush.
Actually MB recommend not to do it for a couple of reasons ,also by $ 40 a Quart it is saving you money
Great Video I just did it on my 2017 GLS the 2 rear screws are a little different to reach but also blocked by a big bracket MB don't makes it easy to work on their cars
Thank you so much for your comment. I really don’t feel comfortable leaving the oil in the converter. You do this oils change every 60k so why not go a little further and changing what is in the converter.
German engineering is very complex but it’s also the best when it comes to cars. So yeah they don’t really make it easy for anything. I’m glad my video was helpful.
Great video Jose. Thanks for the time put into providing such a thorough explanation. Concerning the torque converter, if the fluid is draining too slowly, starting and immediately stopping the engine will cause the fluid to come gushing out. You will have to line up the opening again to replace the drain plug.
Thank you so much for your comment. And thank you for the tip!
Safety first is right!! I always put a condom on when I work on my cars 😂
Thank you so much for watching my videos and for your comment.
I’m surprised Mercedes didn’t and you also didn’t drill a hole to get that odd bolt out from above the trans mount.
Thank you so much for your comment. It would have been easier if they designed it with that in mind. But I wouldn’t be the one to change their engineering. Maybe a little hole won’t change much, but I rather not.
Really appreciate that sir !
You are welcome
I can't understand the reason why someone would service the 9g automatic transmission at his house. You buy a car like a mercedes, and you know that you will need money for maintenance, right? I am also a mechanic and I have the E300de, but I am taking it to the Mercedes dealership so that I have all the guarantees because I paid 110,000 euros for its acquisition.
and as you know, the specific automatic transmission has enormous technology and a mistake might turn out to be fatal...!!! you are a good engineer and great video. my knowledge is to go to an official car repair shop so that we can have peace of mind... as long as you have money of course..thanks!,🙏🏼
Thank you so much for your comment.
I am actually doing this as a hobby, I am not a mechanic, or I guess you could say I am, lol. I have been taking care of my cars for like 20 years. I just don’t see why you couldn’t drive a luxurious car and pay the same money for it (used of course) that you would pay for a regular car and drive in style. I really don’t see the difference in doing the trans service on a 9G transmission from a Mercedes or Nissan than on a regular Chevrolet transmission where you follow the same kind of procedure. You are right in all the electronics and craziness involved, but as long as you do it correctly and follow procedure you should be okay.
So I don’t think you need to have the money to pay for the maintenance, if you can do it yourself, after all the procedures are the same as in any other vehicle. Plus, you don’t do this kind of service on a 110,000 euro Mercedes you are doing it on a 15k or 20k euro Mercedes after 60k miles when the factory warranty is done. The trans service where I live is $1400. I spent $300.
Thank you so much for watching my videos. I appreciate you taking the time and writing your comment. We need to have this conversations so people could really see the pros and cons. Hope to hear more from you in this or any of my other videos. And if you have a channel, please share so we can learn what you do as well.
@@josecitomarin agree with you 💯 👏
@@lownology thank you so much
Amazing and very educational video
Glad you think so!
You made my day! use a service such as S M Zeus!!
Thank you
Excellent work.
Thank you so much
Excellent detailed video.
I've recently had 9g oil and pan changed at Automatic transmission rebuild specialist, refill was 5 and half litres they didn't drain torque converter.
Should I be concerned?
Thank you for your comment. I would say your oil is half way clean. It’s not terrible but it would’ve been good to do the entire thing. I hope the old oil wasn’t too bad.
What a great video!
Thank you so much
I can only speak to the Nissan Titan, but I believe they only got the 9-Speed Jatco from 2020-2024. Prior to that, there was a 7-speed Aisin transmission, not sure if the maintenance procedure would be the same.
Thank you so much for your comment. Jatco is actually licensed for production of the Mercedes 9G-Tronic transmission for some of their Nissan and Infinity vehicles
@@josecitomarindoes it mean they have exact same valve body, TCU and solenoids? Are they interchangeable between Nissan and Mercedes brand parts?
@ for the ones that have the same transmission yes.
Great job!!cheers.
Thank you so much
Great video and thanks for sharing. Were you guys spinning the engine counter clockwise? Shouldn’t be the other way?
Thank you so much for your comment. Can’t exactly remember what I did on that day but if you move it counterclockwise will be ok, it’s only until you get that bolt to where you have access to it. Go very slowly so you don’t miss it
Great video. Very thorough. Any concerns with the torque converter running dry for a few seconds (or minutes?) until the 5 "extra" quarts from the pan cycles through?
Thank you so much for your comment. No concerns at all. That has been the procedure for many transmissions models for years.
Great thorough step by step video
Thank you
I have a glc 220d 4 Matic , when do u recommend to change the transmission oil
Your suggestion would be appreciated
Have you heard about Liqui Moly brand ?
Thank you so much for your comment. You have to do it every 60k as well. Liqui Moly is great. I use a lot of their products. Take a look at my other videos as well you’ll see the products I use.
Thank you Jose
Just changed oil with Liqui Moly top tec4200 n added Ceratec
Engine much quieter and responsive too
Thank u 🙏🏻
@@dino69xsx that is great. Thank you so much for your comment
Very informative video
Thank you for your comment
Great video! Just to confirm, you don’t need to cycle through the gears after filling and waiting for temp to reach 39 degrees, correct? Also, on a 9g tronic MCT (AMG only) w/o torque converter, does the 9 liters drain from just the pan or somewhere else after draining from the pan? Does anyone know?
Thank you Artur for your comment. There is no need for cycle. I took 9 liters out and I put a little over 9 liters back, so I am very comfortable with it. I do not think it makes a difference to cycle through gears. I don’t like the idea of running it dry even though it would only be for a fraction of time and not completely dry. Another reason I am comfortable with it is that I change the oil before time and not after.
With the MTC. I have not done one my self, but the way I have seen it done is that (and it might sound silly) you drain the oil from the pan and from the cooler hoses two times. On the first change the oil that is left will mix with the new oil and when you do the second oil change you will have much better, cleaner oil in the trans. Now, with this procedure, you run the engine after you have changed the first time (wet trans), go through gears so you can get all of the oil moving throughout the entire system, get up to operating temperature, let it run for a few minutes and then flush again.
If you do it your self it doesn’t cost you much. And since you do not do this service all the time is not too much of a pain. The car is already up and ready. I would also have the car warmed up before I do even the first change. Bring the car up to operating temperature, and let it cool off for a few minutes. Wear gloves so you don’t burn yourself.
Hi , i have 2019 E63S. Is this method also applicable to my car?
Also, torque converter drain is absolutely necessary? Or can I skip?
My car just hit 40k miles.
I just realized i have MCT without torque converter..
Hey. Beautiful car. Right. Your transmission is slightly different. No torque converter. But it’s basically a 9gtrinic. You still have some miles before you have to service it. But it’s also a good idea to do it before
@@josecitomarinso if i dont have torque converter, i dont need 10L of fluid? I drained from pan and only 4L came out.
@@Johnmam9984 no. You only need about 4L
Hi Jose
Can u change the oil without the pan change ! What’s ur view?
Run it for another 20miles and change the whole filter kit
I would just change the whole thing. It doesn’t really makes sense to do that. Just change it all and wait another 60k to do it again. I’m doing it every 50k
Thanks. Sounds good 👍
@@dino69xsx no problem
I thought the rest of the oil was in the transmission oil cooler that has a feed via the two pipes that come from the transmission housing, to drain this you have to run the engine to operate the oil pump with the return pipe disconnected and add and drain a litre at a time? ( 4.5 litre in the transmission and 4.5 litre in the oil radiator )
You say you got 4.5 litre out of the torque convertor, was this also coming from the transmission oil cooler?
Hi. Thank you so much for watching my video and commenting on it.
The amount of oil that is held in the radiator is very little. It doesn’t make a difference. There are people that don’t even drain the torque converter. I got 9 liters out and I put just a little more then 9 in. And that is what the 9g-Tronic trans (with all its components) on this car calls for.
As you mentioned, some of the oil from the lines may already come out from the torque converter, but what is being held is not a significant amount to make a difference on the operation of the transmission or the lifespan of it. So I am not really worried about it.
Thanks!
No problem
fantastic!!!
Glad you like it!
Jose, excellent vid! What’s the size of those wooden blocks? Thanks.
Thank you so much for your comment. They are 6x10x20
hi am i right in hearing that 9litres of oil are needed to do this? i heard about people doing a flush. i.e dropping everything out the pan about 4 litres doing a flush then doing again with new pan and oil about 4.5 litres. your method has 9litres in one go by draining the the torque converter direct. which seems better tbf as is all the oil in one go rather than leaving half in and being contaminated. im currently on 61k mikes and 7years on a s213 model.
Thank you so much for your comment. You definitely drain from the torque converter. That way you take it all out.
@josecitomarin that's what I thought, thank you for your reply. I can't believe some people are changing half the oil and calling it an oil change. the pan and half the oil is like 90% of the cost anyway. Good to see it done properly 👍
@@julianlandeau right. It’s not even difficult to get the fluid out of the converter. Just needs patience
Jose, greetings from Portugal. Made a great video very detailed. Can you tell me which OBD diagnostic tool you use and also the one for the mobile phone? Thanks.
Hello Jose from Portugal. Thank you so much for your comment. The ones I used are iCarsoft CR Ultra and the one for the phone is the Kobra OBD2. I know the iCarsoft one is available in Europe. Not sure about the Kobra. But they have more in Europe. iCarsoft also has others that are just for a particular car, check out their website. No fees for upgrades. Make sure to take a look at this short I made on those scanners. Also, if you didn’t already please subscribe, like and watch more of my videos.

Is there any kind of upgrades for the torque converter and clutch pack? I need it for my 23 Nissan Titan Pro-4x, the transmission is having issues. Let me know
Hi. You can certainly make upgrades, specially tune the trans and get different application performance
Hi Jose, thank you. Would you post the link of the scanner you got from Amazon, if you don’t mind?
Of course here you go. I just saw it and price went up. But it’s still cheap. $31. When I bought it it was $19 then it went up to $25. I use it in a few of my videos

Does the car have to be on neutral for the torque converter screw to show?
Thank you so much for your comment. No need to put it in neutral

Did you add 10 liters at one time and then drain the excess at point 3? Do you advise me to do the same with Liqui Moly 236.17 oil?
Thank you so much for your comment. Add the same amount of oil you take out and then adjust as needed. The amount of oil will also depend on whether you do the torque converter or not. Yes you can use liquid moly. That one is for 9gtrinics
One last question: Did you add 10 liters at once before starting the car?
@@Lesnafe no I did not
Not everything in the video is clear like a motorcycle and how to fill it up.
Great video Jose. Did you change the filters? I didn't see that step.
I have the 2015 S550 with the 7G transmission. Would the procedure be similar to yours?
It’s very similar. I got the part at FCP Euro. They will help you find the correct parts for your car. Give them a call
@@josecitomarin will do, did you change the transmission filters?
The filters and seal come in the tray already installed. Some cars come with the filter and seal already installed and asome separate
Thanks Jose for the detailed explanation! I appreciate it.
@@atrzebunianiebies any time
Great content! What is the tools you use to read of oil temp to 39 degrees?
That is an OBD2 scanner. You can get a $20 scanner from Amazon or you can get a better one that is bidirectional from specialized companies. I used both on the video. The bigger one is from Icarsoft. The one from Amazon will give you codes and live data is great. The bidirectional will allow you to send commands to the car as well.
Alright. Thanks 🙏
@@lownology you are welcome
@@josecitomarin Hi again Jose! i´m now about to change oil on my 9g trans. If i took 6 lites out and I put a little over 6 liters back. I still have to do 39 degrees check?
@@lownologyyou should definitely look for the temperature measurement. Make sure you do the torque converter. Get the scanner you’ll need it for other things as well. Anybody who owns a car should own a scanner
What kind of torque wrench you using?
www.lexivon.com/collections/torque-tools
what position do you set it at to set the fluid level?
You set it in position 3
When you go back under after measuring temp, what initial position do you out the tool into, position 1? Then, turn to position 3 and let it drain, then back to 1? Thanks!
Thank you so much for your comment. Yes, you start at position 1 then change to position 2 to drain slow. Then to 3 and back to position 1.
@josecitomarin Thank you. Got it done today. I was freaking out when it started pouring out steady, but then it stopped and dripped. Car still runs like a champ, but the fluid was pretty dirty for transmission fluid. Thanks so much again!
@@TheFrenchPug no problem. I’m glad it worked out.
@josecitomarin I used the original pan and filter because I ordered the wrong filter and gasket online based on their confirmation that our transmission was a 2018 c300 with a 729 transmission. All the videos I watched on 2018 C300 showed the pan with 6 bolts and a separate filter, reusable pan. Once I got under the car, shock and awe struck me and I panicked because I didn't have the proper tools to refill the pan and had to Amazon 1 day order them for $20.
So, I spent an extra $90 for no reason. But, I got it done. And, I found the fluid for $8.39 a liter and ordered 10. So, I have 5 for next time and will just order a new pan at 100k miles.
@@TheFrenchPug just don’t wait too long to do the next change. Who knows how that filter was

I don't have a scanner to measure the temperature to measure the fluid level, does anyone know the way to check the temperature without having the scanner on 9 speed automatic transmission? On my old mercedes 2014 ML350 the ATF oil pan is metal and it doesn't require to change the whole pan but only the gasket when it comes to ATF service...I usually check the temp through my laser temperature tool by pointing it to the ATF pan while the engine is running. It reads the temp without having to use the scanner, but since the 9 speed comes with plastic ATF pan my laser tool probably won't read the temp correctly through the plastic pan, though I have not tried it yet, if anyone have an idea about this please help answer my question. I appreciate in advance for your time
Thank you so much for sharing. You can simply get the small scanner from Amazon for $25 and you connect it to your phone. If not your laser tool will work. Just go up a little higher in the transmission to the metal. In my video I showed how the $25 scanner works perfectly
Hi Jose. I have a 2017 C300 convertible equipped with 9g tronic transmission. They told me that I just need 5 liters of transmission fluid since the pan will drop 4 liters and the torque converter drops only 500 ml, is that correct?
Thank you so much for your comment. As far as I know you need about 10 liters for a trans service. Even the 7g tronic needs about 10 liters
Hey man, the main cap on my car is leaking oil, I have oil changed 8 months ago. Can I just replace with the new cap? Thanks
Hi. Thank you so much for your comment. It doesn’t hurt to replace it. They are very inexpensive. Specially if you know that it’s leaking from the cap for sure. But you are going to have to refill your transmission again.
@@josecitomarin Hey man thanks for the reply. Why do you suggest refill again?
@@EdasTattoo well. The cap is on the bottom of the tray. You are talking about the transmission right? Or are you talking about the engine? If it’s the engine no need to refill. And if it is the transmission, you don’t want to use the same oil after you take it out to change the cap. Who knows how much oil the car leaked by now.
@@josecitomarin Thanks for your reply. Im talking about transmission yes, it didn't leaked much, its just wet a bit. Once i remove the old cap, it will not start to drain as it has second cap inside for filling and draining isn't it?
@@EdasTattoo yes . You are correct. Remove the cap. The fill tube is inside
Now I see why this service is so expensive 😩
Thank you so much for your comment. Yes they do charge a lot, it needs some work, a lot of oil, new pan, new filter, etc
Another reason mechanics hate engineers.
It takes a little longer than a regular car. But is not that bad.
Maybe, but it’s unnecessarily complicated and you have to buy the stupid tool.
@@bobmcgehee1749 it’s still a lot cheaper then having it done by somebody else. And then you have to make sure they do it right, which is the most important part.
