MERCEDES GLC300 X253 9G-TRONIC TRANSMISSION OIL FILTER FLUID HOW TO SERVICE CHANGE REPLACE PROCEDURE 

Glad you enjoyed it! Thanks for the support! 😁

Thanks 👍😊

Not only they overcomplicate it but also the Check Level Procedure DOES NOT actually work! I have tried multiple times and the oil never stops flowing from the pipe when it's setup in the Check Level position! I mean I was very very frustrated of why they made it like this in the first place! Then they ask you to check it with some radar tool or whatever it was, which sorry how many people are doing to have these?! I am yet to see one at the smaller independent shops... Thanks and Good Luck 👍🤞

@@projectathos yes correct. The truth is they want owners to bring to Mercedes dealership for services, they want to discourage the DIY mechanics and even independent shops. That’s ok, we always find a way! 👍🏼

Yea 5L an your good, just like the older gen with the level shaft for oil level

Let me correct myself. You poured 5l because 4.5l came out of the gearbox. but how did so little oil come out because supposedly 9l of oil goes into it?

The reason why you see only 4.5L come out is because the reat is in the Valve Body above the oil pan and also inside the transmission and lastly in the Torque Converter. The plastic tool you need to buy separately but I would recommend buying the metal version as I already got the metal upgraded version because is more solid and you don't want that tool breaking in the parts you are changing. That tools is available all over the place like amazon ebay and so forth - Mercedes 9G transmission service tool should be called. You are not supposed to replace the whole fluid in your transmission and I will give you my explanation here that I already posted earlier replying to another person here. This topic about changing the whole fluid out or "flushing" seems to be very controversial and I will try to explain my reasons here - the way transmissions work is very different from let's say the engines. In the Engine when you do an oil change you do indeed need to change the whole fluid! You are not supposed to leave any dirt particles because they can get in the galleries and destroy your bearings that work on microns of tolerance! Now with transmissions this is the opposite! I have rebuilt transmissions myself and have studied them before doing so. I also have enough knowledge which I always try to gather more by the way by studying everything I want to do in advance... So in your transmission you have so called packages or drums of clutches that are actually soaked in the transmission fluid. In order for those to start moving so that your car starts moving you need the fluid that creates the compression where the clutches are compressed against the metal plates between the clutches. There's also a partial friction physical law that happens so that those clutches start moving. So what I have seen through the years is that if you do not do your regular maintenance of changing this fluid in your transmission the clutches will still work but the fluid because it gets burnt by the friction of the clutches will start destroying the transmission and technically burning the clutches. Then you would say yes this is the case where you need to always replace the whole fluid so that it's fresh and it doesn't burn the clutches. But there is another situation happening at the same time while the transmission is working. Your clutches release very fine particles into the fluid and those particles actually help the clutches to work the way they're supposed to work. What I have seen when people replaced or flushed the whole transmission they actually ended up taking out those foreign particles and therefore leaving a bigger gap between the clutches. Next thing that you can guess is they started burning their clutches because of the gap and the new transmission fluid which doesn't have the power to fill those gaps. I would say that you may flush a transmission anywhere in the range of up to 50,000 miles because the clutches are still new and the new fluid will not damage them. Meanwhile if you actually change partially your fluid every 30 to 40,000 Miles you would be able to get a very prolonged life expectancy of your transmission! Remember your transmission is not made to last forever! Those clutches are made to wear out no matter what! All the cars that we have owned and I have done the partial service have lasted up to 300,000 miles with no problem! Meanwhile I have seen multiple times on customers vehicles when someone replaced their complete fluid and the transmission started slipping immediately! I even know a friend who did this full flush service on a couple different Brands of cars he had just bought against my advice and ended up burning up both transmissions! He had to get rid of those cars very fast! This is why we always keep the old fluids for a little bit longer after we do the service to make sure that we don't have a bad reaction from the clutches so that we need to install the old fluid back in to make the transmission run back normally. At that point you are only going to prolong the inevitable anyway! This is my experience from what I have seen and have done this many times and this is why I'm sharing this information and this is why I do the service the way I do it. I cannot vouch for what anybody else will tell you and why they will claim that their way is the best thing to do. Unfortunately Mercedes does not explain this information to you nor any other company for that matter! Not to mention that on other German brands the transmission fluid is not supposed to be replaced according to those same manufacturers... Thanks and Good Luck! 👍

Vannila Radio Smooth & Sexy. Find it online. Thanks

hi, nice one. but i thought after filling in the oil, there suppose one more step to check for the oil level and drain the excessive oil?

It looks like you have the AMG Speedshift MCT 7 speed transmission which is different from the 7G-Tronic ones. You would need to get 6 bottles in case you need some extra but make sure when you get the old one out to keep it and measure how much you got out. Also make sure to get the proper fluid for your car because it will be different from the 7G-TRONIC. Thanks and Good Luck 👍🤞

Yes, all Transmissions are vented on the top through either a pipe or a valve with a cap. They are manufactured in this way in case of an overfill. Thanks and Good Luck! 🤞💪👍

The machine was hand made by a technician. It just has a fluid pump with some piping is what it is... Thanks👍

Thanks for the excellent explanation. I had heard a version of that reasoning years ago, thought it was maybe only true for an old piece of junk car you wanted to sell so you change half the ugly, dirty, burnt oil to make it look better, leaving some old to hopefully prevent slippage but the buyer doesn't know the trans is going bad. I've always used Amsoil and do a 100% change every 50K. Its always so clean I wonder why I'm doing it. My theory being, yes there is wear but if the premium fluid is so clean then there has been very little wear so I don't need to leave residual in an expectation the trans is getting worn out. I haven't been a professional mechanic so my experience is limited to personal vehicles only. I had a Ford E350 that was used to tow a boat through the desert. Loved that 460 BTW. Sold it with about a 100,000 miles never had a problem. Likewise with a 93 400E. 185,000 miles and the trans was still perfect. I even ran that car hard on the track at Willow Springs with a racing club. Now my Ram 2500 with the cummins diesel has 350,000. Manual Trans and transfer case call for ATF. So far so good.

​@@bentleyjarrard885Why were you towing a boat through a desert? I'm genuinely curious lol.

@@insanelywicked873 The Colorado river as well as Lake Mead, Lake Powell, lake Havasu are in desert regions. If you live in the greater Los Angeles area you are towing through the desert, sometimes when its 115 degrees to get to the destination.

Nice to know. I don't live anywhere near a desert.

Didn't know the Frontier had this transmission... Strange to be on a Nissan too... 😐👍

As I explained before you are not supposed to change the whole oil because you can destroy your transmission when the clutches start slipping because of the new oil. Again Mercedes DOES NOT recommend a complete fluid change but only a partial one. This is what this video is about. Thanks 👍

⁠​⁠@@projectathosЗдравей моя майстор го смени със машина 10 лт вкара и стана лошо между 1 и 2 започва да рита леко.Сега какво трябва да направя? Виждъл съм и много клипове тук със машина сменят!

No need to change the oil in the converter. It's not recommended by Mercedes either. There's a huge risk of creating slipping conditions when the whole fluid is changed. Hence the partial fluid change which is actually recommended by Mercedes. Thanks 👍

@@projectathosThen why not just leave the pan and filter then drain and fill?

Well, this is a very precise job and it needs to be with extreme care so you don't end up with a leak after the change and so forth. So it's up to you whether you would want to pay to someone to do it and possibly try doing it yourself. Thanks 👍

Very precise my donkey hole. This is on 50% of Mopar vehicles during the same time frame.
