9G Tronic Transmission Service Fluid Level Check known as 9Speed 725.0 NAG3 W9A700 JR913E

[@Kattakam]

Nice work, lots of people are commenting and making it seem like wizardry but in the end the new filters and fluid will keep until the next flush.

[@antonyweaver357]

Great video! I have seen several videos on the 725 kit that range from ok/good to almost unwatchable! So glad to say that yours is steady, really informative and you show the annoyances & workarounds needed in the real world… Top job - thanks for your efforts! 🙏👍👏

[@LazaroMonroy-Batista]

Very good video. If you are doing this job make sure you have the correct chassis, if you have model 166 or 292 the transmission temperature to set level is 59 C not 39 C. but all other steps in this video are correct. Thanks for sharing

[@gingerjessy]

Just a tip on the transmission oils as I work on Mercs but only done one of these 9 speed transmissions so wanted a refresher. The oil you had there gives earlier spec stuff on the tin. 236.14 red oil. Older transmissions without start stop. 236.15 blue oil. 7 speed with start stop. FE (fuel efficiency) 236.17 gold. New 9 speed transmission. 9G tronic. Mercedes are a nightmare for changing part numbers. The black tube inside the pan which doesn't do anything is for external ultrasound level reading. Special tool.

[@YepThatsIt]

thanks for that. cheers

[@chrisa840]

Mercedes technican here. the 722.9 trans (7g) uses red oil 236.14 if its model year 10 or under. and it uses blue oil 236.15 if its model year 11 or up. remember mercedes changes model year in the middle of the year. the 725 trans (9g) uses 236.17 oil in the trans and 236.15 oil in the transfer case. i have done more oil changes on these than i have wanted to do lol.

[@rokg601]

Nice video, Theres a drain plug in the torque converter you can undo to drain 4 more litres. Remove rubber plug under bell housing, Then rotate crank pulley until you see plug, Its a 4mm hex and takes a while to fully drain

[@YepThatsIt]

awesome info, always good to share..cheers for that

And it's a very soft screw....easily strippable.

[@BoqnSlavkov]

Sorry about the question but can you show me where exactly is that plug in the torque converter. And which is torque converter. I’ll do it by myself

[@rokg601]

@@BoqnSlavkov Just in front of the pan, there is a rubber or plastic plug, you pry it out(its just a dust cover). Then you have to turn/rotate the crankshaft pulley with a socket+ratchet while looking through the hole where the plug/dust cover was with inspection light until you see 4mm hex head bolt. Remove bolt to drain torque converter, it drains slowly so will take 15mins or so.

[@halleffect1]

I would like to do this but how the hell to turn the engine? the crank pulley is completely blocked by the intercooler, the alt pulley has no hex, there's nothing to put a socket wrench on..

[@dennisdewald6729]

Why didn't you drain toque converter?

[@YepThatsIt]

hi, i seem to get this same question regularly ! typically hydraulics is not same as engine or gearbox/differential/transfer case service. we only ever do a complete flush if coolant/water has entered transmission, owner specifically requests complete flush or incorrect fluid has somehow been added. generally by replacing with fresh fluid with what comes out of transmission, is adequate to re-boost oil qualities/properties. but however having said that, we also like to use lubegard products to help enhance the fluid properties. it is more beneficial to do a regular transmission filter service ( not just a fluid drop ) add extra magnets and to also bypass the heat exchanger or radiator to eliminate chance of coolant entering trans and to help keep fluid cooler, this helps to retain the fluid properties longer as it breaks down with heat. choice is yours cheers

[@b.d.1145]

What happened to drain torque converter and tranny adaptation ?

[@sawekkosut795]

Have you changed the oil in the wandler

[@YepThatsIt]

hi, i am assuming a wandler is a torque converter ? no, the fluid in torque converter wasnt changed. we only flush as much fluid out of trans when fluid has coolant in it. doing a normal pan drop is sufficient to boost the fluid properties. if the fluid is very burnt and contaminated then a full flush usually makes trans worse because contaminated fluid is usually thicker than new clean fluid, so if you have internal wear and pressure leaks, thinner new fluid will leak through those locations much easier. on these transmissions a hot flush is usually done to clean out the thermal valve that is in cooling line. the only way to flush a torque converter is to cut it open. if you know the operation of a torque converter you will know alot of heat and high flow pass through it anyway. cheers

[@sawekkosut795]

thank you for the answer, I have not had contact with such a transmission. this is my private car and I wonder if the replacement is exactly the same as the 7g tronic. some say you must have a service program with an oil level check function.

Could u possibly post the part number for that silver fill adapter u used for filling?

[@Deszii90]

How often or after how many km does it need transmission service?

[@YepThatsIt]

hi, we recommend transmission filter service every 50,000km when trans has done under 200,000km, then when over 200,000km service every 25,000km. dont forget to add magnets and bypass heat exchanger. cheers

[@bengleckl1877]

So number 1 to add. Number 4 to drain and if I want to check fluid level after refilling then I'm selecting number 3?

[@YepThatsIt]

hi, watch the vid again. will make more sense once you start doing it. cheers

[@kosta16auto]

@@YepThatsIt, but those are torque-to-yield bolts (4nm + 90 degrees), and they have been stretched already on the first time this pan was installed. And if you apply the same procedure, then the risk of breaking them is high. I had cases where I simply didn't have the bolts, but I would then tighten them by feel and not carry the 90-degree procedure.

[@tonton4818]

Hey buddy, how about 3-4 liters in torque converter? Not changing 50% of the oil is really bad job.

[@YepThatsIt]

hi, in an auto transmission the fluid is there mainly for lubrication and hydraulic purposes. this is why you buy transmission oil, but once its in the transmission it becomes fluid. trans fluid is not like engine oil, whereas it also acts like a filter and needs more frequent changing. we only do a full flush/fluid change when coolant or water has entered the transmission. however we have done job/tests and found, that to effectively change all the fluid properly and completely, you will need to do it 4 or 5 or more times. thats alot of oil ! you can check our other vids related to your statement kzbin.info/www/bejne/Z6HEomiIl86HhLM & kzbin.info/www/bejne/jJbYZptrmtuHn7s if there are no issues and you are doing just a trans service, it is more important to clean the pan and magnets ( add magnets as well ) and replace filter/s, just replacing the fluid that comes out is generally enough to boost the fluids required properties ( we also recommend to add lubegard products )....many people compare transmission service to an engine service, and many will just do an oil drain without removing and cleaning the magnets and filter service, if the trans pan has a drain plug. choice is yours ! we will do whatever the customer decides when they are explained the options. cheers

[@kosta16auto]

nowadays torque converters don't hold 3-4 liters anymore. This specific model will be able to drain about 500ml-600ml.

@@YepThatsItthank you for the reply . Just a question so I went ahead and removed the drain plug with the car OFF fluid was coming out !!. Does that mean it’s overfilled because in the video when you first removed the drain plug to start changing the fluid nothing was coming out . I closed it back up and started the car and went down after going through all the gears of course I removed the plug nothing was coming out so I added 500 ml then waited for the temp to hit 39 then flicked to position 3 until a trickle flow coming out like in the video and closed it . What do you think ? Cheers 🥂

Not the correct procedure. You need to let the oil out of the torque convertor first and the stream in position 3 was to much you should have let it dribble out much more and then check fill level in the scanner en do the adaptation. Would not be happy if i was the customer and i saw this

@@alinemotorcare8903 in the Sentry software to check the level without an ultrasonic gauge, you have to bleed the 5 valves in the trans with the software, then get the car between 2800-3500 rpm for 2 second in neutral, then idle rpm, then around 1200 rpm is when you do the measurement with the key, the software will automatically set the RPMs for the last part.

[@statusquoreject]

You’re supposed to cycle though the different gears (PRNDL) at operating temp and then check the oil level, why did you not perform that part of the process? Skipping it means you didn’t cycle the trans fluid through the valve bodies and thus the trans fluid level could be off.
