- Josh walks us through replacing the valve body plate and the TCM plug on the widely used 722.6 transmissions found in thousands of Mercedes cars from the late 90s to mid-'00s. eEuroparts.com carries the plate and plug itself, as well as a kit.
Go to eEuroparts.com if your Mercedes Benz is having trouble shifting correctly, and get back on the road safely with this fix! A dealer or Authorized MB service center TCM reset is required for the fix to take. Most likely the car will be stuck in 1st gear until the transmission is reset.

I guess I'll pile on say that that was one of the best auto repair "how to" videos I've seen. Excellent presentation and very clear instructions. Thank you for posting!

Where is this guy at? This is my type of clean cut repair! Look at that impact tool wrapped with a bag while he's taking off the conductor plate... Now that is detail oriented!!! Love it
By far the best 722.6 video on RUclips. Great job!
Boom! Awesome to find a good mechanic guy that can make clear succinct videos. Subscribed.
I love the in depth & hands on video, not like the others that rush through & skip half of the important steps. Great video dude!!!
Without a doubt the best" how to " videos I've seen. Well done Sir.
A true professional. They're lucky to have you.
One of my favorite place to shop at. I'm so lucky I live 25 minutes away.
Well explained !!! Thank you
Clear clean precise 👌 need more of your kind on these kinds of vids
Finally a normal person who knows his business
Excellent video, wish you would comment on bolt size whenever removing. Thanks.
Fantastic video, greatly appreciate the time and effort you went to make this easy to follow, fantastic job. Thank you once again
You're welcome, thanks for shopping at eEuroparts!
THANK YOU FOR A DETAIL INFORMATION VIDEO. GOOD GOING
You're welcome, thanks for shopping at eEuroparts!
@@Eeuroparts @ 5:25 a ball bearing is falling out, and it's still there @7:10, so where does it come from? Because i'm going
to do the same job to my transmission next week, so this ball popping out worries me.
Btw, how did the car run, without that ball bearing? Because i didn't see you refit it.
Best by far. I am a mechanical person by trade and I am a big fan of these DIY videos. I have an 06 E350 4matic @ 106K and have been doing all the maintenance myself and this was tops by far!!
TY
Thanks for the video. This was the most physically challenging repairs I have ever done because I had to do it on 2 jackstands and my shoulders are tanked. I still don't have the ATF topped off. I added 3.7 quarts, then 200ml at a time. But I have to wait a long time to get an accurate measurement with the dipstick because the ATF kind of clings to the fill tube. Anyway, my P0715 code is gone and it shifts! Thanks for a great video.
Thanks, brother. Good video that Ill reference again in the near future.
Man great video, was concerned about that ball bearing that popped out when the conductor plate was removed. Looked like it just went unnoticed through out video. Hope that didn't create and future check valved issues. Great video thanks so much.
It was kept track of, just a flaw in editing
That's very observant to spot that! I wonder where the ball bearing was from
Very clear instructions, camera angles and speaking. Thanks! I won't be doing this myself because I live in an apartment and don't have a way to jack up my W220 s430. But I wanted to see what is involved when my mercedes mechanice does the work. Thanks again.
Great video bud the step by step commentary was spot on thumbs up from me 👍👍👍
Great video! But with all that work I would’ve added in the sleeve kit as well. Worked wonders. I do it all the time. Subscribed btw :)
By sleeve kit do you mean the overlap control bushing kit?
Thanks for this. My transmission stated slipping today and pretty sure it's the conductor plate/ electrical issue. This video would allow me to DYI but, I live in an apartment complex so going to take the car to my Indie shop.
Excellent video, did you drain the torque converter as well? It seems a shame to put new fluid in if half the old stuff is still in the torque converter.
you forgot to show one important step the yellow sliding gear selector has to line up or you will be stuck between gears i know because i made that mistake
I made the mistake put the piece but we got it fix
Excellent! My W210 has the problem before and done the replacement of the plug and circuit board. Thanks.
Just ordered it, thanks for the vid will be coming back once its delivered hopefully it turns out great
Hi Angel, How much it cost you for the conductor plate ?
Cool informative video Josh! Thanks
Thanks for the video Josh very thorough
Josh, hopefully you're checking this. Of the 6 solenoids, it's obvious which two are the pressure solenoids based on shape alone, but the other 4 - the Lockup, 2/3, 1/2&4/5 and the 3/4, are those four solenoids interchangeable? I've noticed slightly different part numbers and didn't know if those might just be MB revision numbers or if there are specific ones for each of those 4 solenoids. I got an unusual condition just 24 hours after installation in that when downshifting (say 4th to 2nd), the trans shifted real hard then revved but it didn't actually downshift. I immediately put it in neutral and coasted to a stop. I re-engaged into drive and all was fine. Won't try it again but I'm wondering if I have a misplaced solenoid or even a bad one from the kit I bought. Thanks!
Nice easy to follow video, well done.
I've taken off the pan and found a different gearbox from your description, on the valve body is written AB-AA-AAAAA. It has the plug, but it is sitting vertically! After draining the fluid & removing the pan, I then set about disconnecting the plug from hell. Yes, it was soaking wet with transmission oil! There is one orange ring in the plug & it's damaged! We are talking of a seven speed transmission. What to do?...... I wonder whether I can just replace the seal, plug it all back in, re-fill with new filter & hopefully the reset will work?....... Really hoping you might know or have a vidio on this 7 speed box!........ Thank you in advance.
Excellent video sir .. j have an 03 e500 intermittent link mode no check engine light ..my question does the new conductor plate have to be reprogrammed ?
Glad I found this video will help my on my 06 Chrysler 300c because it uses 722.6
Thank you for a no-nonsense direct audio/video explanation. What is the torque setting on those valve body bolts as I couldn't hear if you said 7" or 17" inch lbs? What is the torque setting for the pan bolts?
72 in lbs
I have a s500 and i have a problem in the gear box the shfting to the second speed is too sloly
Can you help me ?
i have the same code for clk 2004 my car stick in first gear all time won't shift at all, so you replace the part and did not make any change?
Do you perhaps have a video on how to test and repair the 722.6 AT Shifter Assembly with winter sumer switch and 1/2/3/4 selections
Great video. Thank you for explaining. My Mercedes has winding noises as it get kind of hot. Is this related to the winding noise?
GReat video! but, how to you remove the whole transmission??
Same fault on my Mercedes C Class W203, 2003 model of gear won´t shift. And once the gear refuse to shift the chock will stop functioning and the packing sensor will go off. please we need your response.
Great work! Thanks. I will attempt this though I have to work with the box still tact underneath.
its really great video to learn too. just have 1 question does the conductor plate requires any software programming before or after ?
That plate has been commanded from ECU ( car computer) . Only execute the commands that ECU give . Is a "slave" part and dont think need to be programmed
Great video, makes me think I can go lift my e240 and replace the solenoids right now!
Is it amust that TCM computer be reset?
Hello, my SLK 230 transmission fluid is leaking. and i can see where it is leaking ... it looks like vacuum cable where there is a rubber boots and another end is connected to transmission... would be kind enough to give some suggestion
Hi I have this gearbox fitted to my car and it wont drive. In neutral and park it will rev freely as it should but in D and R it will only rev to 2k and won't even try to move an inch. It's had a new conductor plate but no luck. What else could be of course ? Great video by the way very easy to follow and understand. Great work ❤
Hi what is the symptoms of wrong adjustment 722.6 modulator and how to adjust it
If plug adapter is leaking fluid no codes or shifting problems can you just replace adapter to fix leak or must you replace conductor plate also for leak ?
have a CLK 2006, and it's got stuck in 'get you home mode'. Started doing strange things two years ago, switching off and on again restored normal operation for about a year. Then it started again, same thing. Suddenly got worse now locked in some sort of default. Tried to reset it, even worse now!...... 60K miles only, light use. I assume the Transmission Valve Body Plate and Plug have gone wrong. Am I in the right area. If I replace the unit and service the box with fresh oil and filter, will the computer go back to it's original setting. Some advise would be very helpful indeed.
Hi Josh... thank you for your video really helpful.
I have a 2007 mercedes benz c280 and the other day i got a code P0705 on my OBD II says Transmission range sensor. My question is where exactly in the conductor plate is this (TRS) sensor?
Thank you for your advise
Your transmission is a 722.9 completely different transmission with a anti-theft device inside of it a whole nother world then this transmission 722.6
You have no idea how this video has saved my ass!
I took out the valve body to move the pins around because they got a little bent while putting the plug in, straighten those out now my car is stuck in neutral, wont shift into reverse or drive, please help
Thank you for very good and detailed video
Good video, thanks for very clear instructions 👍😎👌👍😎
Keep hearing so many different things about this job. Do you have to program all that to the engine once you are done?
Great demo!
Great video, now I understand. Thank you.
I can ask you for the tightening torque of the bolts of the whole gearbox, thanks
Great video. Have you ever had one of these were you use the kick down on the throttle the gearbox goes into a weird gear change mode as when you accelerate the car she stays around 1000rpm and up shifts all the way to 7th no throttle response and slowly goes faster. Hope I described that ok.
Typically that is a failing Accelerator Position Sensor/Throttle Position Sensor. If there is something wrong with the APS/TPS the DME will typically detect a failure when you apply 100% throttle. It will then go into the limp mode and act the way you describe.
@@trakdv362 thanks for the reply, it’s a pity she hasn’t thrown a code.
Great video.
I have 07 E350 4matic, it would not shift gears while it revs up, I followed the video step by step, replaced the TCM plug and the conductor plate, however, the problem still exist. also, the manual speed "techtronic" would not shift either. all solenoids are at 5 Ohms except for one at 3 ohms. ???? any idea what the problem could be???
Need to clear TCM codes with a diagnostics tool or at the dealer.
Great video! Thanks. A couple of questions. Do the solenoid hold down bolts require torquing? Second, should the solenoids be inspected and tested when I have them out? I figured it might be a good idea, especially on an older car.
I did this same job twice e500 and s500 I tested the solenoids cleaned the screens and installed the sonnax kits one very important point he does not mention in the video is the gear selector it has to fit back into the groove on the selector or your gears will not work and if you install the sonnax tcc damper both half have to be separated and the retainer ring has to hold the tcc valve in place but if you do not have the 722.6 diagram o would not attempt this because it's a possibility that the check balls can come out...but yes always check the solenoid with a ohm meter or 12v battery
I was wondering can you confer that transmissions to manual. I have s600 1999 and s420 1998 so I would like to convert one to manual. Please anything help and willing let you do it on my trany let me know I live in colorado
What are the symptoms of these component's failures?
Help lol im getting a shudder in low rpm just trying to maintain speed it also happens when im slowing down if i put it in manual mode with the auto stick it goes away anyone have any suggestions i did a fluid and filter the fluid looked good
hi good video iam working on this paticular trasmission i check on my solened valve resistance every thing good i want to check on resistance of conductor plate pls feed me back thanks
I only have one problem with this video when you pooped up the conductor plate a little metal ball flew out you can see in the video I’d imagine that was important so where would it go if I had to put it back ?
Great video!! I have a 2006 S500 with the 722.6. Would you know if I replace the transmission connector do I need to reprogram the car?
The transmission connector is just a piece of plastic so it should have no effect on any electronics. No reprogramming required.
This is beautifully done.
Why didn't you check the solonoids while you had this apart? Just curious.
Really very nice video!!! Thank you so much!
You're welcome, thanks for shopping at eEuroparts!
When changing conductor plate did u have to reprogram it or was it just swap and computer can work straight with it I ordered kit of eBay wondering known brand
my question too, so what did you end up doing?
what diesel engine fit onto the 722.408 petrol gearbox
I have a 2000 Mercedes c280 at first it wouldn't shift out of park my mechanic fixed that now it won't shift out of first what do u think it is it ran fine before this no hard shifting at all please help
Good job Josh.
How do I get a 2001 S500 W220 out of limp mode at home?
great video i actually need this done on my s550 how can i get it to you guys shop?
hi
great video easy to follow thanks
Can this gear box work on w126 with a 606 engine but automatically driven?
very informative video, well done
Does 2010 have same problems
At the time 7.10 where did that ball bearing come from, i saw it come out when he took the conductor plate off.
You mean at 5:20... I saw that too, but didn't realize it was possibly a bearing until I saw your comment. It most likely came out of the valve body, there are a few of them in there.
is that black rubb plug on the top of trans the fluid fill point?
Hello does the 98 e300 need the conductor plate replaced as well?
Cam the Solenoids be Purchased Seperately?
Do you need to relearn or re tune the tcu after the change?
Hi. There is the problem in my car’s transmission. When the transmission changes from 3 to 2 , the “tak” sound comes from the bottom of the machine. Car w210, 1997, engine 111(E230). Please say me, what could be the problem?
Thank you so much, I may have to do this going to try a new plug 1st I have 2005 jeep grand
Excellent video. If I had to add anything to the video I would have shown the gasket replacement for the pan and maybe point out torque converter drain plug if that's what I think I saw.
I wish he would've touched on torque converter as well. Alot of fluid left in it.
How many quarts of atf do you need to refill it. And also they told me it doesn’t need to be programmed on my 06 Cls 55 AMG
Thanks for the tip. The transmission take around 9l for a complete fill of ROWE ATF 9004 www.eeuroparts.com/Parts/419880/Auto-Trans-Fluid-HIGHTEC-ATF-9004-1-Liter-25050001003/
What kind of spray did you use on the transmission pan area?
Random Vids brake cleaner
Is there a trouble code that advises you to do this work, or common sense maintenance or shifting problems.Although preferably to have the tranny out of vehicle, can this service be easily done while on car? Perhaps for some us a few more comments on torque specs i.e pan bolts.Thank you, as m any others have stared
Hi John, this work can be done in the car, it is just shown outside because it would be easier to demonstrate. Although we try our best to be thorough, our videos are used as demonstrations, not detailed instructions. We advise getting a service manual do to any major work on your car. Therein you will find details such as torque specs
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?
Most likely the problem described in this video
Please help..how do service a Mercedes V class automatic transmission on w638
...2002 2.2cdi ...4HP-20 thanks
thank you for the video... Very good Job..!!
Hi Josh, Do you know if just the plug can be changed without draining the transmission? I had the fluid changed only 4 months ago and expensive for just the fluid? If the plug is removed will it lose loads of fluid? Cheers
Tim yes
If you mean the connector plug, then no. Remove splash shield. Spray clean area. Unplug it by turning white collar. The rest is in video (except plug harness in before replacing splash shield, obviously)
Can these faulty components cause a sticky reverse valve?
I am working on this gearbox but my problem is the valve body not the conduct plate I change it it works for some time and failed and I service it it didn't work so I don't know if I miss it some were pls help me out thanks
Great video well done
My car won’t go into reverse after I changed the conductor plate?
I have a 1987 300sdl with reverse but nothing forward. What would you suggest I look at first.
Car only has 170k miles
Josh excellent video.
I have merecedes e class 2005 (w211). Its stuck in 2nd gear.
I ran a cheap obdII scanner and it gave an error P0715, which is "input/ turbine speed senson "A" circuit).
I replaced the 13 connector plug but had no luck. Do you think i need to replace the electrical plate which has the 2 sensors as you did in this video. Thanks
Thanks
idk if you have done so yet but yes 100%. that plate is garbage and fails.
I am replacing the plate. I had same problem. Stuck in second gear.
@@chrismontreuil2206 If u have for 1999 model, change pressure regulator spring. It is often problem on those gearboxes.
Updates?
Either the plate or one of the solenoids is bad.
Could I put my old valve body and conductor plate in my new transmission
139/5000
Why is there a 3 to 4 second delay before entering gear, after changing the body valve, selenoils, filter, shifter, etc.?
It's a good Video.
I recomended to clean the parts with cleaner
