Awesome video. Thanks so much for making it.
Very educative thanks, my w211 E350 has a similar problem
What problem
Fantastic video!!! Thanks so much!!!
very kind of you, thank you
awesome video
Fantastic video! 👍🏻 I’m doing this myself tomorrow, any idea what’s torques are required for the refit please? Would be much appreciated 👍🏻

What was the customer complaint? I am curious on symptoms as I have an 08 Mercedes ML 320 CDI with occasional hard upshift/downshift. Seems to be random but plan on using SDS to scan for codes. I have seen most issues on 722.9 are result of Conductor plate (sometimes solenoids but not usually) and torque converter sometimes.
Very good video
Super.
Whats the torque on the wishbone plate things that hold the solenoids? Im buttoning things up and need to torque mines down. Im guessing 8nm
Topically, what is the cost on one of these jobs? Also is it possible to replace it with a used Valve body conductor plate and then have it reprogram? Thanks
Est-il possible de mettre un module deuxième génération a la place de celui de première génération d origine ??
what's you price to change transmission fluid and filter ?
very useful video. I have a problem with my 7G transmission where it shows in the scanner tool a fault in transmission speed sensor! would applying cleaning technique by degreaser for all sensors on the TCM help?
there is a good chance the conductor plate will
need replacing, how ever if you are on a budget and can carry out the work your
self give it a good clean and give it a go, you may experience slightly harsh up
and down shifts afterwards while everything try's to re adapt it self.
did you manege to fix it by cleaning?
Thank you for sharing this video . Great and helpful . Im having problem with same gearbox on my ml320 , that has hard shifting on gear 2to3 and 3to2 especially on lower speed , in very hard. When i accelerate it stars to dissappear . Can you please suggest me any solution . may be a good clean like you shared should resolve my problem? thank you
There is a modified shift solenoid that you can replace for harsh gear change from 2-3rd get it booking in at a garage with a star diagnostics and they will be able to check for you to confirm if this is possible on yor vehicle.
Hello , thank you for your reply , can you please tell me where i can buy this selenoid , olso if you have a sparepart code , in my country is difficult to find this information . If yoy can please tell me . Best Regards
Indrt
seleniod has to be purchased from the dealer but the correct one needs to be diagnosed :)
SPR Autos ok thank you for your reply , so i need to aske the dealer for modified selenoid about my transmision for gear 2to 3 right? Thank u
yes, i would ask for a software update at the same time on your gearbox.
Hello, if i buy a online programmed conductor plate (i have a TCM y3/8n4 fault) do i still need a xentry or star system to make it work ?
Also do you recommend to change solenoids ?
Great video !!
im not sure on that, I buy the part direct from dealer and does not come programmed as you can see in the video. maybe ask the person your buying it off if it still needs entry Scn coding for confirmation.
Hi, I see that you used brake cleaner to clean all the valves. I was going to use electrical cleaner but the instructions say not yto use anything else the nATF and a magnet ? Is it safe? Im about to open my 2008 722.9 and clean the valve body/conductor plate, all i need is a new pan gasket and filter, everything else I can reuse if I find no fault correct ?
yes that is correct, yes the MB instructions say not to use any cleaners other than fresh ATF fluid, i have used my method for 12 years and never had a problem, but the decision is up to you, just make sure all parts are dry before refitting.
2007 s550....my issue started today after few minutes of driving, gassed up, than went to start car and gears wouldnt come out of park, engine light popped up, u0101 code. eventually went into gears and was drivable however some rough shifts. is this what the issue might be???
thx!
its always a possibility how ever i would get your self booked into a good independent that has good diagnostic equipment that can troubleshoot your problem.
Hello dears, I'm planning to change the y3/8n1 and n2 after a limp mode, diag give the p2768 witch says that the y3/8n2 is defective... my car is a w204 from 2012 with that 722.9 gearbox, should I recode the tcu or the gearbox after changing speed sensors please ?
Your help will be so much appreciated,
Sincerely yours
Hi there yes the speed plate should be SCN online programmed after it has been replaced with a genuine new product, if you are having your current one repaired at an ecu specialist then there will be no need for programming. :)
Hello I have a question I am I send the conductor plate for repair 722.9 I am replacing it my self how much transmission fluid I need 6 quarts off fluid came out off the car. I also want to know if I could use a obd 2 scanner to reset the codes or which one I need. Thank you
hi there, you will need to pump in 6.5 liters of fluid, get the gearbox upto 36-40 degree temperature and then drain fluid back out 'while engine ins running in park' until it reaches the level straw. As soon as it starts spitting put the drain plug back in.
Great tutorial, thank you very much, one question: do you have to reprogram the conductor plate ?
yes must be re programmed with online mercedes star system.
@@sprautos Thank you for your answer, do you have a link to buy the conductor plate ? My my car is a W164 (like you on this video) :)
no problem, condutor plate has to be purchased from mercedes dealer
I did the whole job and didn’t know I had to program is Can a Autel scanner program it ☹️
Hello, I have a question. My car is 1998 W202 C180 automatic transmission. When I start to drive the car the first and second gears don't change quickly. I should wait long for the changing of gears. After changing the gears it gets normal. I changed the oil because of it but the problem with gears weren't solved. What problem could it be?
did you change the filter at the same time? i would get a specialist with star diagnostics to check the faults for you and check shift data.
When changing out the valve body on the 722.9 does it have to be reprogrammed by Mercedes once installed either used or new?
yes it has to be programmed online using a Xentry Mercedes machine, you cannot fit a used one as it will have a chassis number off it from the previous car and this will not allow your car to start if the vins don't match. there are some places that can make a used control unit virgin so you can be re coded online.
What are you using to clean the parts? Great video
Brake cleaner probably
I will also replace conductor plate, do i need an computer to learn the transmisson with the new Part?
Should i replace the Valves? Or is the problem only about that plate?
yes it will need a mercedes star machine, and online programming. must be done with someone who has a online star machine otherwise you will not be able to programme it to the vehicle.
@@sprautos how much will that cost?
Does the 07 ML 63 need to be programmed on the conductor plate? and Ken like $1000 OBD reprogram it or introduce it to it
Yes it will need to be programmed. We have done a more recent video on an SLk explains more in detail.
Great video! I am having my conductor plate repaired right now by a specialist and wanted to clean the valve body while I wait. I like how you used the brake/parts cleaner to clean the outside of the valve body. Did you have to open the valve body and clean the inside for this vehicle?
thank you for your kind comment, we didn't open the inside of the body, opening the inside is quite a big job with lots of tiny components and has to be done very carefully and isn't something i would recommend doing unless it is necessary. Hope this helps :)
other video say not to use brake cleaner to clean the val body is that true
@@roymccree5324it is true.
Awesome video. Just a question. Does the valve body module need reprogramming after it is replaced? o_0
Hi Thomas yes the module will need reprogrming once replaced
Ok, thanks.
I have a '97 722.6 - USA model, that is slipping while shifting into 3rd gear.
But when it's in 3rd it holds tight.
So I am thinking if I could disconnect the pressure control solenoid than it would shift hard on full pressure and fixing my problem.
Do you think this would work?
And what is the easiest way to disconnect and what color wire should I cut or disconnect so I don't have to take the oil pan off?
I am not that familiar with this transmission.
Thanks
i am not sure what wire you wold need to disconnect, We wouldn't recommend this as a repair :(
I am not asking you to recommend it.
Could you just tell me what color are the wires going to the shift pressure control solenoid on the outside of the trans?
Thanks
i don't know what color the wires re i would have to check on a wiring diagram
@SPR Auto i got a c class 05 stuck in second gear according with directfix say to chance the esp/bas?
i would get your car booked in with a specialist or dealer to have a star diagnostics carried out to be certain what the problem is and get a full diagnostics print out.
But yes ABS sensors can cause gerbox limp mode.
@@sprautos can I replace abs sensor without any programing?
@@fredc8618 yes you can replace ABS sensor without programming.
Hi i just watched your video..im currently working with a 2004 mercedez s500 5.0L with the 722.9...it has a torque converter lock up code which seems to be an electrical code..we have rebuilt the unit and replaced the tcc solenoid..after erasing the dtc it comes back..my question is in the video you have replaced the conductor board..is the tcu being replaced along with it and if so those it need to be reprogrammed also..my other question is ive repaired a similar setup in the nissans Re5r05a unit where its conductor plate and tcu are one piece and are made by the same manufactuer that makes the tcu and conductor plate along with the solenoids..ive opened them up and found broken tabs from the solenoid lead circuits that goes back to the tcu and solder them and they work fine my question is mainly can i detach the tcu from its conductor board and replace it with another conductor board or can their be a broken solenoid lead as i mentioned with the nissan units be repaired
the ecu which is replaced in the video cannot be changed with one from another vehicle it has to be new and then coded via the SCN coding mercedes system. the other alternative is to have your current one reconditioned with a ecu repairing company.
Can I get the song that is playing on this video, as there are no Shazam results.
I have a 2008 Sprinter 2500, removing the valve body to have a peek at the conductor plate. The electrical connector will not come loose and I don’t want to break it. Any advice?
Pray it off gently from outside of transmission case.
I found what was holding it, there was a 7mm bolt in the middle of it that you can't see without a mirror and light. Kind of ridiculous. Thanks though! God bless!
David Santana we are on our back fixing this while everyone else is using a hoist. Makes a big difference.
Hi there,
If you remove the valve body from the transmission for simply cleaning the solenoid screens and rpm sensors will there be error codes or reprogramming required after. Great video
Regards David
no you should be ok, shift quality might change slightly but it will adapt as you drive. :)
DO U NEED USE SCAN TOOL TO REPROGRAMMING THE TRANSMIISON AFTER THAT?
If you have just cleaned everything no, but if you wish to carry out online Xentry programming then yes, this will have to be done via a dealer.
Great video i have c300 w205 2015 with 40k miles on it i have a problem with the transmission when its is in gear one and two the car while moving and rpm is going up the rpm goes down a bit and the car shakes it feels like the car shifts but it didn’t and then the rpm comes back up and shift harsh it’s very noticeable when changine from gear 2 to 3 and downshift from 3 to 2 i can’t find any error codes and can’t fix the problem please advice me what to do , do i need to change the transmission fluid or what please help it’s destroying my car experience and i am in different country so please advice me i only had it for 4 months
As a starting point with you having no fault codes i would have your gearbox fluid and filter replaced and see if this improves your shifting.
I have the same issue after fluid and filter change. Before there was no issue at all.
@@kevinchang5655 any updates having the same problem
Duke107 Full revision of the transmission, cooling fluid has leaked to the transmission, it was a mess.
@@kevinchang5655 wow mercedes are great but thats ideal is dumb my transmission coolant line popped off from the radiator while entering the freeway now my car has a jerk during 4th gear
How did you program the new conductor plate?
online mercedes star diagnstic is required for programming,
Is the connector supposed to have some play on the connector plate? (wiggles)
as in the connector where the wiring harness plugs into? yes it does move slightly and is very sensitive so handle with care when removing/refitting the valve body.
I have a problem with benz w211 280 2007. When raising gears 1 and 2 give me a little shake. what can I do if you can help me
have you taken the car to be plugged into a star diagnostics for further investigation?
transmission oil changed??
Hi i was hoping for some advice i had my car in a mercedes specialist by the name of dronsfield in royton oldham the did a service A and a gear box oil change my car was faultless going in to theyre garage but since the day i picked it up the theres been an issue when put into drive it does like a thud then goes in to gear in reverse its worse it makes a loud thud then like a delay going in to gear any advice would be greatly appreciated thanks
hi, i would take it back and let them have a look into the complaint and demonstrate what you are not happy with and give them the opportunity to sort it out.
@@sprautos hi iv took it back to them but they cant seem to put a finger what it is they said they have ran a full diagnostic check on it no fault or error has been detected they have said in might be torque converter or valve body or something along the lines but i dont understand i have read up on torque converter and non of the symptoms match its literally when you put it on reverse or drive but when its driving its fine no gear interchange problems runs smooth? They are waiting on a few opinions of different technichians so i have to wait till they contact i saw your video and thought to see if you can help with some advice or opinion thanks.
how did you do the drive authorization system?post it as well
this is done via star diagnostics using online account
I have a problem, change the SCN or TCM to my mercedes benz ML500 w166 trans, 722.9 and it is giving me some jerks down and up gear the mechanic tells me that it will be adapting since the part is new and not adapted handling and etc etc, is that true? I am afraid that it could cause something worse
depends how bad the jerk is but sometimes yes driving the car for 1000 miles while it adapts and smooths out gear changes is required if still the same after that return to mechanic
@@sprautos now I see that my vehicle does not exceed 4k RPM, is it normal?
@@emmanueldrk2 no this is not normal this requires looking into
My local dealership quoted me $3500 to replace my valve body on 18' cla 250. Is it viable for me to replace myself or should I let the professionals handle this? For what it's worth, I am not a mechanic, but I have been in manual labor and know how to handle tools.
You would need an online star diagnostics machine to be able to programme it to the car.
Nice work! How much does it cost for this repair ?
thank you, around £1200 UK
Hi about how much will the cost for this job? where are located? thanks in advanced!
Hi alex, we charge £700 plus vat for the job, this includes oil, filter, gasket, cunductor plate, online SCN programming, labour
We are based in manchester/stockport www.sprautos.com
Many Thanks
nice working there am also mechanic need Sam to work with
What degreaser did you use to clean it.thanks
We use brake cleaner and never had an issue as long as you leave the parts to dry. Mercedes say to use fresh ATF fluid to clean the parts with but its down to personal choice. Hope this helps :)
@@sprautos thank you
Hi, I changed this part yesterday on my c63. My mechanic told me they programmed the module before hand and then installed it, after that he just cleared the codes several times and now it's gone. My question is, is that possible or he just bullshitting me?
Hi Pedro, we programme the units when fitted to the vehicle via the OBD port with Mercedes diagnostic software using there online programming service.
There is tools available that can read your information off you old unit and transfer to your new unit on the bench 'off the car' so yes this can be done but not something be personally do.
Do you use a Brand new part?
@@sprautos Yes brand new. If its bullshit, It will probably give me the check engine light after a few runs. Thank you for responding, good information too
Dude I cannot get the valve body back up under the car to complete the job ...its like it's not aligning up and when it does the black thing by where the gear selector keeps blocking it
make sure the gear slector peg lines up with the slide on the valve body as it can slide around when putting it back up, need a spotter really to make sure it goes up correctly.
why did you change the conductor plate , was there fault codes can you tell me what they was , or was there another reason ?
we changed the plate due to a faulty speed sensor, there are many different codes that can occur which will require the plate to be changed :)
ok thanks
hi sir i m auto electricion.i have xentry tool but i can.t make condecter plate program
you must be able to program online and carry out SCN coding.
SPR Autos thank for reply sir
Hello, do I need to do matching learning after replacing the valve body computer board in my car? The problem I have now is that it is very difficult to change gears after switching the computer board. Do you know what the problem is? There is also no fault code for the gearbox.
Why did you use infrared thermometer , when you have Xentry ;)
no particular reason, well spotted though ;)
Can you make SCN coding for Transmission control unit? It must be online?
SCN coding must be done online for the control unit.

What name is the song?
not to sure our video editor found it for us.
Thanks, but like for this movie ;)
hi, where are you located?
We are in stockport, manchester.
:)
You don't show where the gear shift is positioned
what is the part number?
the part number will depend on weather you go for a new unit or a reconditioned unit.
reconditioned part number is A000 270 26 00 / 80
this should be checked with your chassis number with Mercedes.
How much do you charge for this? Is it common for them to fail much?
We do this job as a package price for £640 plus VAT www.mercedescarservicing.co.uk/mercedes_servicing_spr_autos_prices.html :)
Do you have anyone in Germany that can do this job?
There should be plenty of Mercedes specialists i would of thought in Germany.

Anyone keep what was wrong y it had to be replaced
the speed sensor had failed on the plate
Old oil was green. You put new oil it was red???
when the fluid is burnt and worn it turns gree/brown colour fresh oil is red
