Issues with Mercedes transmission?? no communication with VGS? VGS defective? turbine speed sensor not reading, Transmission won't shift out of second gear?? watch this video!

[@shckltnebay]

Mine had an issue at 47k and was serviced at MB at 39k so how was mine at maintenance issue? Its a defective unit, NOT lack of maintenance!

[@glasser2819]

Benz are built to generate repair business regardless of high maintenance cost. It may be a good idea to RESET ADAPTATIONS after an ATF service... different shift points and better oil pressures 👍🏻

[@danray267]

Hi there. I have a 95 Sl320. I lost reverse. Need to see about getting the transmission conductor replace. What's the average cost for this model.

[@federicotorresbordils7624]

Do you need to make adaptations with MB software or just reinstall and run ? BimmerN53

[@albarr9158]

Excellent information mate. Thanks MUCH for the information and I'll be sure to spread it.. I just paid the dealer $2200 for the repair. I can confirm that you can only get the part combined with the valve body and you have to be a dealer/certified to get it. I did the conductor plate repair on a 722.5 and was expecting to do same on a 2006 cl500 (722.901)..nope

Mercedes now recommends servicing the transmission (fluid and filter change w/o torque converter fluid change) every 39,000 miles. I recently changed mine and plan to do it again at 20,000 to 25,000 miles since I did not drain the torque converter. It was done by the dealer at 42,000 miles and the invoice showed only 6 liters of fluid were used. The torque converter holds about another 4 liters. FCP Euro has the service kit (with 6 liters) for $83 shipped and I figure that's cheap insurance.

[@glasser2819]

yep, it's as simple as that! Also forget about WOT and redline... older automatic gear boxes like the low-rpm duty else the shaft bearings and the countless clutches simply get shot!! High performance is possible but only for a reduced time 😂

[@gopranro]

Great video ... do you know which one of the solenoids is solenoid 'A' ?

[@MercedesBenzTechs]

It’s not the solenoids, it’s the whole control unit, I never had a case of bad solenoid, not even once. The control unit fails and can’t actuate the solenoid and you get a fault that the solenoid is bad, you need a new TCU.

[@Calsonic8899]

[@volvoguy2373]

Why cant we just change the bad speed sensors? Like all the guys do at the "circuit board repair shops do for $260..... I mean its not that hard to "youtube" search a Guy with a hammer a punch and 2 speed sensors... Just source the speed sensors and change them...That is if that is your only code anyways... AKA turbine speed sensor...

[@glasser2819]

@@volvoguy2373 the Benz network would rather not have you spend $200 in sensors in place of their royal traitement for $2,500. Why do you think they go bad like clock work? 40 yrs ago I had a cheap Honda bike with a built-in centrifugal oil cleaner that kept the oil free from clutch and aluminum contaminants... somehow Germans best engineers can no longer figure out how to deep clean ATF, seriously 😂

[@buddybestor]

End users can still do it. In fact, it's probably easier.. we just need to take the conductor plate out, send it off to circuitboardmedics. They will refurbish all the solenoids and sensors for only $400 bucks and you won't have to reprogram your car either since it's going back on the same circuit board. You will still have to have a special tool to measure the temperature when putting the transmission fluid back in. They'll even loan you the tool for that!

[@MercedesBenzTechs]

It’s only a temporary repair and only when you have issue with the speed sensor, there are so many other things that can go wrong with this plate..(thanks for taking the “bla bla bla” out, shows you are a little more mature).

[@thomasmcghee3]

Honestly, I like your individual info. I'm in California by Thousand Oaks. I have a 2007 s550 with the 722.9. Do you know of any shops( that are reasonable) out here? My car more than likely has contaminated fluid because it has this rocking motion when I drive up hills and sometimes when I'm coasting along at 35mph. It's not shifting into those upper gears correctly unless I use my paddle shifters. Contaminated fluid could be causing my torque converter to be acting incorrectly.

[@adra8409]

[@kkyong340]

Hi David, I have a 2006 E200 and recently the fuel consumption seems to have doubled. The engine mounting units have been changed because I am getting vibration on the passenger side. However, the next problem is that the transmission will have a "cloak" sound when shifting from "D" to "N" and from "R" to "P". There is absolutely no sound swifting in opposite direction. Could it be due to the conductor plate malfunction or "torque converter?

[@emada4874]

i changed front control arms on my CLK500 2006, and after i drove away, car went into limp-in mode. i got P0702 code . I know for sure that the mechanic took off the wheel knuckle without taking off speed sensor and it got stretched . most likely got broken ! i cleared the code and disconnected the battery but no luck . Do you think speed sensor would do cause the car to get into limp mode ? or would it be just a coincident that TCU broke at the same time ? Thanks in advance .

[@mitchell198990]

I have a 2008 350 c that went into limp mode . I scanned it using the obd 2 and it comes up as U0101 transmission control module communication loss. I checked a few things and found the connector that enters the transmission had oil in it and was shorting between pins. I cleaned it on both sides with contact cleaner and still no communication. Why would oil be in this location ? What's next?

Fault on computer……... bad or no signal, speed related…. Cleared. and now, it’s doing exactly the same game! If I restart the car, she’s back to normal until the next longer fast run. Apart from cleaning the multi plug, I didn’t touch anything. The multi plug was wet inside! and my techi mind tells me that there is some magnitic shit in and around that beautiful bit of black plastic! If I clean this board, all those solonoids and put it back together again, what are my chances! I already build classic gearboxes for my job, so I am brave, but never stupid (I hope). Thanks for the help and great video.

Hello . I have a Mercedes SL320 R129 . It has 115,271 original miles . The transmission shifts and works perfectly driving it forward but when it's put it in reverse , I gently press the gas and the engine revs like the transmission is in neutral and after about 20 or 25 seconds , the transmission will work and can be driven in reverse. Can the conductor plate be the issue ? I haven't had time to really look for leaks , etc . It does have transmission fluid in it . I've ordered a Mercedes diagnostic tool but it hasn't came in yet . I live in Rome , GA , about an hour drive from Atlanta. Can you please give me your contact information ? I have more questions and perhaps you can build a transmission if needed. I don't really trust anyone here to do transmission work on my Mercedes. I have two R129's and I work on them myself when applicable. I'm really impressed with your knowledge of the Mercedes transmission. Best Regards

Here is a question for you on a Mercedes 5-speed 722.6 transmission. When I drive it hard and once in a blue moon the transmission would slip in gear and then catches itself about 1/2 second later. No CEL. We did pull a code from Star tool. it was P0730 Incorrect Gear Ratio. The transmission pump seal, valve body conductor plate and pilot bushing was replace. I'm running out of options to why it does this but I was thinking the next thing is transmission and torque converter full flush.

You may need to rebuild your transmission... On manual when it slips it might be the clutch..

[@glasser2819]

change the oil TWICE to flush the most crud possible out of the transmission system. Then do a simple "ADAPTATIONS RESET" with key on/off to force the computer to relearn the shifting pressures and shift points. If it is still the same after 500Mi gentle driving valve body needs the replacement shown in this video to get CLEANED UNIT (with latest software). If you have a good scanner dig in the live data to see improvements else $2 to 3,000USD... the parts (solenoids + sensors) are dirt cheap but this simple repair is bread and butter business...

Good video man. I recently bought a 2007 s550 the original owner stated one day it wouldnt shift it would go into gear but not move.Low and behold the day i go to buy it the car engaged all gears and drove fine. Four days later after i bought it i put it into drive and nothing it just revs up. I have a shop and i work on a fair share of european cars. So i hooked my autel scan tool up to it and got a u0101 code (Lost Communication with Transmission Control Module) does that sound like a conductor plate problem to you. he told me he had the ism changed many many years ago but if it was a bad ism im sure it wouldnt shift out park and everything else.

[@MercedesBenzTechs]

Cornell Johnson ISM stands for intelligent Servo Module, it’s the square plastic piece attached to the transmission on the side, it’s sole purpose is to electronically shift the transmission from P to N R and D, you will hear a noise as it shifts sounds like ZZZITT... Now, if you hear the shifting noise but yet nothing happen and the car won’t move at all, you need to look into your transmission pump, since even if your control unit is bad the car will go into a limp mode where it still moving foreword but not shifting.... disconnect your transmission cooler line and start the engine, is fluids shooting out the hose??? If not, replace transmission etc.,. If it does look into new TCM etc...., regardless, God Bless!!!

[@jhossecruz8971]

Excellent video could not have explained the replacement procedure any better. I gave the video a thumbs up and subscribed to your channel . I am able to get a new conductor plate through a technician at a mb dealer He has my title and vin is verified for the trp part. I also have access to xentry and the multiplexer , I have a question before I remove the faulty conductor plate do I retrieve the information from the faulty control unit? then after new control unit is installed do I transfer the information from the old control unit to the new one. Or can I just install the clean control unit and scn code it ? Also I’m going to borrow the xentry tablet and mutiplexer so I will be in offline mode will I be able to scn code or do I have to be logged in with a D7 number and to the mb server? Thank you.

[@MercedesBenzTechs]

Jhosse Cruz thanks for your kind words, I always go through initial start of already installed control unit and do the whole installation including SCN which requires a D7, I never tried to transfer from one to another although it’s an option and I’m not sure if you do or don’t need D7 for that purpose but it’s always better to have an access to MB headquarters when you install new modules, and if you do have D7 go ahead and update ME (motor electronics) as well

[@craiglewis9956]

Outstanding video and information. I have a 2011 S63 and plan to do a service oil and filter change on the transmission. I understand that the conductor plate has to be ordered by an authorized dealer/technician. Can they order it, program it and I install myself? Another question I have is if the conductor plate and valve body is removed are removed for cleaning does that alter the module in the conductor plate as far as needing reprograming

[@MercedesBenzTechs]

Craig Lewis thanks for watching. If the quality of the fluid is not too bad do not remove the valve body, the plug where the wire harness connects is very sensitive and may brake upon removal! No programing is needed if you use the same conductor plate (vgs). Every authorized TRP shop or dealer can order install and program TCU.

[@MercedesBenzTechs]

devin dodson you can't, the VGS, known as conductor plate is considered as a TRP (theft relevant part) and is designated to the vehicle it was initially coded in to, if you take one with or without the valve body it will not work on other vehicles however, you. An change the valve body if you wish without the VGS as long as you use identical part number (220 454 3607 etc).

Hi, I have ML 350 4matic 2014 with a 722.9. I do some trailer towing popup trailer) 110k miles. Serviced trans twice. I would like to install an aftermarket trans fluid temp gauge and aux cooler. Do you think this aftermarket gauge will interfere with the electronics and the cooler will change the press drastically? Thanks

[@MercedesBenzTechs]

Good point, I’m not sure, you can try and check pressure on the new cooler.

Hi, I am ready to install my transmission cooler, but I was wondering. The lines connected from trans to the radiator, talking about flow direction, which one is flowing from trans to radiator and other one from radiator to transmission flow wise. Do you know which one is which? Thanks for your help.

Hi, by any chance do you know the size of flex hose (ID) of the trans cooler flex lines of a ML350 2014. Trying to install my transmission cooler and some cooler are 5/16 and other 3/8. Just want to match it with the ID size of the factory flex hose ID size. Thanks

Great info. Thanks for sharing. I have a 2014 E350. It comes with the updated transmission (7G Tronic Plus). When I called Mercedes dealer to ask about the service, I was told that the service interval for the updated transmissions (after 2012) is pushed back from 40k to 70k miles. Does that sound right to you? My car has 55k miles on it and I'm thinking to perform the service sooner than 70k, maybe at the 60k service.

Hello. I currently have a 2013- GLK350 - 276engine, with 52668miles. When I bought it had 45,356 miles. One day, engine light came on and it turns on. It's the tcm. I've had it service with new valve body and plate, my transmission is still jerking from 4th to 5th gear (23mph to 33-35mph). At Mercedes Benz of Boston - I keep hearing it's that it's program right and they've checked the conductor plate etc... now they've sent the info to Germany to see what is the solution. Can you help. Please? The feels smooth except for the transmission. When I bought the truck, it shifted suuuper smooth, like a dream. Please help!

[@1ELiMusic]

Another thing, although the plate is new, the computer does not recognize that the plate has been replaced. As if nothing ever happened.

[@MercedesBenzTechs]

1ELiMusic I had a customer that went to the dealer and changed the valve and TCU and the transmission was acting up, after that the dealer recommended him to change the transmission and he declined and came to my shop, we decided to change the valve body and TCU again and it fixed the problem turned out the valve body and the computer were bad... questions, when you shift manually (with the buttons on the steering wheel) does it still doing the same? If doing it manually resolves the issue then the unit is defective. Keep me posted.

[@jaimemelara3104]

Thank you so much, man! I appreciate it. I'm glad I was able to call and I believe it was you who I spoke to. So I just got back from the dealer, as it turns out, Germany suggested to change the plate again. "Hopefully" this solves the issue. ABout what we spoke earlier today. as it turns out "anyone can come up here and buy a transmission without having having any TRP issues. The plate is the same. The only time we ask for the documents is when you need a duplicate key. Are you accusing us of fraud? Because you have the invoices with the part numbers..." At that point I got pissed off and basically said, well it's my car and not your vehicle. It's been here about 7 times already... so you tell me???"

[@MercedesBenzTechs]

Jaime Melara All TRP has to have a proof of ownership!!!! It includes keys, ME TCU ignition switch and steering lock! No dealer is exempt Mercedes is very strict about it, if they get audited by Mercedes and no TRP documentation is presented they will be fined for every and each incident. Regardless, I hope your issues are resolved with the new TCM, VGS. Good luck.

[@jaimemelara3104]

Supposedly they don't have to do that since the vehicle, VIN and myself were there. According to my service adviser, since they got the "OK" from Germany there's no need to prove that I am the rightful owner of the vehicle. They only verify a TRP if it were a key needed and if the vehicle was not there or if it shows no record of ever servicing that vehicle. I'm going to compare all invoices from when I first took it in, to the one now to the one I'll be "hopefully" getting tomorrow.

[@googlehen3600]

Thanks for this informative video! My R230 with 722.9 (7-speed automatic) transmission went into limp mode yesterday. I have spent over $10000 with my mechanic here in Las Vegas but they never recommended me to do a transmission service. Today when they read the error codes it came out as P2725 when they say means "the internal check of component Y3/8y6 (B2 brake control solenoid valve (VGS)) has failed" and they say even though they can do everything such as refurbishing valve bodies etc, there is no cheaper fix than a total transmission overhaul and they quoted me $4995 for that. Does this sound reasonable to you?

[@MercedesBenzTechs]

Google Hen No!! Clearly indicated that you have an electrical internal issue with your transmission control unit and integrated VGS, you need to find someone that can install a new valve body and control unit! Do not rebuild the entire transmission, it’s not necessary.

[@googlehen3600]

The mechanic read out the adaptation data values too. They are: -20, 20, -18, -20, -20 -2000, 2000, -1380, -1300, -1220 They said that these values mean that the transmission is slipping too much. Would you say this conclusion is correct? As far as I can understand, they are within the range arent they? According to the research I have done, valve body is a more likely cause (perhaps even interference caused by metal particles in the oil) just as you point out! They did not do the Star road test as recommended by Mercedes and even though I told them I had seen an oil leak under the car (despite the fact I have gotten them to replace almost every engine seal there is) they did not investigate that leak...

[@chrisej5987]

+Mercedes Benz Techs What are the differences in the valve body/TCU assemblies that make some of them replaceable separately (i.e. Just replacing the TCU) and others where you have to replace them as a whole set? I've read about assemblies being flow tested as a pair but that doesn't make sense to me as the TCU just reads speed and other signals and redirects fluid to different clutch packs. I don't see how the flow characteristics of he valve body would impact operation of the TCU and visa versa. Thanks! Great info in your vid btw.

[@MercedesBenzTechs]

The computer is much more complicated than you think, it also reads speeds sensors, throttle position sensor and yaw rate sensors through out the car, Mercedes changed the diameter of the valves to change shifting ratios.. and shifting quality, not enough time to explain all the changes..

[@MercedesBenzTechs]

Also when you change only the VGS(TCU) as a part of the SCN coding you have to enter the number that is marked on the side of the valve body (220 455 3106) if your valve body is not supported by the new VGS updated software you will not be able to complete SCN, if you try to trick the coding process and write a new valve body number but use the old one (I tried) your car will have incorrect gear ratio coded and go to limp home mode..

[@chrisej5987]

Wow... It's incredible the lengths they went to to make this as expensive as possible when it goes wrong, hahaha. I mean like how on earth does the VGS software know you're lying about the hardware beneath it... lol

When you're in sport mode and coming to a stop, the car downshift to 1st is kinda hard. The downshifting from 2nd to 1st give a little kick. I am not sure when the trans fluid was changed. Probably before 2010 but I read somewhere the issue with the downshifting in sport mode is in the valve body and an upgraded piece of it fixes the problem.

thanks man very helpful. i have 2004 s430 and it gave me that same message but the guy took it out sais its got parts that are broken is that even possible to break? because it started sayin pre save inactive and gave check engine and everytime i put on drive or reverse it did a big kick and it wouldnt change gears was stuck on 1st gear so he said he will repair the original one all for 650

[@MercedesBenzTechs]

Vahan Petrosyan take it to get a second opinion, you can't fix them and I'm not sure if you have 722.6 or 722.9 transmission, on the older transmission (722.6) it shouldn't be too expensive to fix since it's not a theft related part (TRP) Mercedes started the new (722.9) transmissions on S classes in fall of 2004, first check what kind of transmission you have (call the dealer) than have a professional shop do a professional diagnostics.

[@vahanpetrosyan4285]

Mercedes Benz Techs its 722.9 the guy at the shop said its that and he knows a guy who repairs them and had few customers they never complained but is it possible to get pieces broken inside? and what can i do when it kicks on 1st 2nd gears is it the clutch?

[@MercedesBenzTechs]

Vahan Petrosyan no, there can't be any broken pieces inside!! There is guy in CA his name is Chris and he is with G and N motors, he is a Mercedes master tech and he can replace the torbine speed sensors on the VGS (integrated control unit) but it is only a patch, sometimes it works sometimes it doesn't, if your VGS is defective you will have to change both VGS and valve body about $1,800 to $2,000. I would recommend you to save your time and money and do it right the first time, in the long run it will pay off..

[@vahanpetrosyan4285]

Mercedes Benz Techs you are right i will see what happens i dont heva that cash now i told him to go ahead and fix it if i see its problem im taking it to the dealer asap and finish the problem once and for all. thanks sir ur thr best. ill go visit that shop too thanks

[@davidjacov1530]

Better drain, take oil pan out change filter and refill. But I think you can wait a little longer, 50 to 65k...

[@johnyon123]

Thank you :) By the way, can we use the temp gun for refill? I mean... will there be a lot of fluid level difference if we use temperature gun instead of the Star scanner?

[@davidjacov1530]

+John Yon I'm not sure I understand the question, before you drain, make sure you have a tool to fill it back, you will have to fill about 7-8 qt, turn engine on, let it run about 20 minutes, than open drain plug and let excessive oil drain, make sure you plug over flow sleeve back before closing oil pan or you will drain all your fluids out...

[@johnyon123]

what I meant was this: after we refill, we have to run the engine with tranny oil at 45 celcius and drain the excess oil. Star scanner will display the correct temp but I am not sure if the temp gun like Fluke will measure the oil temp correctly

[@davidjacov1530]

+John Yon yes, you should be fine.

rangzeb hussain before you spend money on TCU change the speed sensor, you can clear the fault codes and see if the car moves.

[@lanternofknowledge5619]

Mercedes Benz Techs Hi many thanks for your prompt reply could it simply be something like the speed sensor that will make the transmission not move in Drive etc.

[@MercedesBenzTechs]

rangzeb hussain most likely no, but you have to change the speed sensor first, if it was at my shop I would clear the codes first and see how the car responds, you have several speed sensors through out the car, some on the wheels some internally inside the transmission and one on the engine (CPS) they all have to talk to each other and give identical information as the computer expects, if any one of them is faulty the car will go into a limp mode (but still move) I will need to read codes first to determine what is the issue. Keep me posted

[@lanternofknowledge5619]

[@lanternofknowledge5619]

Hi quick update I have had it diagnosed with a star machine but it's not coming up with any error codes for the transmission and transmission passed all the diagnostic checks on the star machine and you could actually hear it going into all the gears ok so my Indy suspects it could be mechanical and not electrical his next action is to check the ATF levels and also change a faulty rear ABS sensor and help or advice of what to do next would be greatly appreciated.

The valve body is good. Its a 2007 GL450 and it was throwing 0717. I have a friend thats a mechanic who claimed he can change the sensors out, but in the process broke the housing for the sensors and tore the cable. Now it has code 0717 and 2767. So instead of taking to Mercedes, I'm looking for a cheaper way. So that why I asked if I bought a used one, can it be flashed to work plug and play with my truck or will you need the old one to transfer the data. How much would that cost to do?? Im trying to get this done ASAP

[@MercedesBenzTechs]

Richard Atkins depends on year and model but if you need valve body too you are looking at about 2k$

just a transfer of data from one TCM to another.

Great video. I am a former Mercedes Benz tech and I have recently started servicing the 722.9s and it did involve purchasing pump equipment. I recently sent out a 722.9 conductor plate to be repaired because I don't have the ability to perform SCN coding. I also discovered that E350 4matics up to about 2010 I believe still have the 722.6 and only the rwd models have the 722.9 so of course that conductor plate is a straight swap due to the TCM or VGS being remotely located.

[@MercedesBenzTechs]

All Mercedes vehicles after 2006 have 722.9, I have a friend in CA that fixes them.. Google G and N motors, his name is Chris, I personally, just buy a new one but you have to obtain licens to be able to buy it since it's considered as a theft protected part.
