One comment about the K2 piston seal under the flange that needs the 3 rivets drilled out and replaced by 10/32 screws. I have a 1983 380sl (I'm the original owner) with the 722.312 transmission, that was working fine but I had the engine out to be rebuilt so I decided to do the transmission as well. No disrespect intended but I feel like it's a bad idea to simple test the seal for leaks with kerosene. I considered doing what you show in the video, but my gut told me that a 40-year-old seal should be replaced regardless of how difficult it may seem to accomplish at first. The reality is, it wasn't difficult at all and I'm very glad I decided to replace the seal because the seal was a mess. On a more positive note: your video is an essential watch for anyone considering this job. I've watched your video many times start to finish, and it is by far the best video on the topic I have ever seen. Thank you for all your efforts. Ed,
This video proved absolutely essential in the rebuilding of my 722.3 trans.
Thank you very much for you video ! It's very useful for me to rebuilt my 722.3 gearbox !
Excellent, thorough, insightful walk-through... general idea on what is to come for my 722.435... большое спасибо!!
Awesome Andy..keep up the good work. 👍
Thanks
You my friend are a life saver
Glad it helped, Thats the point for doing this.
Obrigado
Hola mucho gusto le escribo para agradecerle por su vídeo el cual realmente gracias a su profesionalismo descubrí que la falla de la transmisión de mi 124 fue por una mala reparación es decir fue mal armada y debido a eso fallo el k1 por suerte encontré el kit de embragues y sellos mandé a reparar el convertidor de torque pero tengo problemas en encontrar la banda de freno trasera acá en chile son muy escasos y excesivamente caros los repuestos de esa transmisión pero insisto gracias a su vídeo logré identificar la falla en el k1 y solo falta conseguir el repuesto faltante para armarla lo felicito gracias
Gracias. Espero que encuentre las piezas y vuelva a poner su coche en la carretera.

Nice work :) i have rebuild mine 722.3 and its not that hard if you have played alot with lego.But thanks for the post ,i have given your link to many do-it-self rebuilders and many of them have rebuild the transmission with succes.Greetings from holland
Dude you’re awesome
Thank you so much please dont delete this video I'm gonna need it when I rebuild my transmission
🛠👍
I just ordered the rebuild kit for my 722.3 that is in My Porsche 928. Just for the sake of it Ill tell you I'm also swapping the torque to with a newly rebuilt one and the torque converter with a 3000 stall converter.. The car is a hot rod/ supercar.with crazy power as well. A NEW or fresh rebuilt trans of this type can take demented levels of power safely.
🛠👍
Класс моладец лайк с меня с подпиской супер, хотелось посматрет видосик по АКПП 722.5 !!!👍👍👍
So, i just finish to rebuild my 722.5 transmission but I have problem with 1st gear and 3-4 upshift. When oil is cold 1st gear is slipping, 3-4 upshift with flare and when I put in D or 3 or 2 it takes about 3 seconds to engage a gear. In R it engages almost imediatelly and drives fine. Problem is only when driving forward. I dont have idea what goes wrong when rebuilding. Is it valve body problem or clutch/band?
Hi Andy , I love your step by step video . Where can get a part number for the damping spring ? Or a source where I can buy it . Lost this spring .
Search Google, all assembly documents i have are downloaded from internet. Look for 722.4 parts book, 722.4 assembly manual, 722.4 service manual.....ect
Thank you Andy a lot for sharing this ❤. I just have one question in my mind right now for the website you bought from the friction rings/plates, gaskets and the O rings.
I do have another question in my mind which is related to correct sequence of the steal plates/ rings and the friction rings.. like from bottom to up.. steal ring/plate then friction ring and close them finally with steal plate. I am talking about K1 & K2. I am just wanna make sure of the sequence.
Thank you Andy.
send me your e-mail...i'll send you assembly manual, you need it if you plan to rebuild your 722.4 transmission.

Thank you Andy so much. I appreciate your help much. I got your mail. Thank you again.
AndyP Mercedes-Benz Channel awesome
Thanks for the video, but you know where i can buy the complete o-ring and clutch kit for my W114 with 722.2 trasmission?
Find a transmission shop that works with mercedes transmissions, maybe they can help you to find a vendor
Thank you very much for such explicit videos. Could you please advice where can we find the mercedes procedures for each job?
it's called WIS/ASRA . look on eBay, some people sell CD's. not expensive. or try Google
@@AndyPMercedesBenzChannel Thank you very much.
Great video thanks for share. Do You know if it is possible swap a 300d that have a 722.3 transmission for 722.4 transmission.
probably yes. I think the housings have same mounting holes and dimensions. What's important are the last 3 numbers in the TX code, like 722.3XX. these indicate the specification of the transmission, you need to match or at least be close for the torque requirements.
@@AndyPMercedesBenzChannel thanks Andy for your advise
Is this also can fix the reverse gear problem, because my Mercedes Benz W202 C200 can not reverse. Thanks for video in sharing knowledge.
That was the problem, I lost reverse.
Great video - thank you.
So... the reverse clutch pack Damping spring (1:31.16- 1:32.37) - is that spring required / necessary / critical? Mine is deformed beyond use. I can;t find it on schematics eitehr. What 's your view? Thank you.
My first impression is that this spring is there to dampen the rattling of the plates when the clutch is idle. I dont see any other purpose for it. How critical is this spring? I dont know, I dont have lots of experience with these transmissions
The gearbox on my W124 is failing. The 5th and the rear gear don´t go. I have removed the gearbox and indeed something is loose inside. I must say I am scared to open it
Hervé Collette .. don't be .. Andy provide a support by this video. Try it why not.
Herve, is your transmission manual or automatic?
It is manual, but I brought it to a gearbox specialist. He has rebuilt it and now the car is fine
All right, good to hear you got it fixed.
Hello. Do you have video to manual transmission.. thanks
Sorry, no manual TX, manual transmissions are very rare in North america
I am rebuilding a 722.6 for a S55 amg. I'm thinking of removing the cushion plates in order to get firmer shifts also trying to add extra frictions. What do you think?
you know, at first i thought you're crazy...but thinking more about it ...this might work. it would be very interesting to see the result. Im not sure if you gonna have enough space to fit one more pair of friction and reaction plates in there.
You most likely will not have enough room for another friction and a steel after removing the cushion springs, but for a faster apply rate on the clutches and a firmer shift, find the oil flow holes in the separater plate and open them up a little bit to get a faster oil flow to the pistons. Also, open up all of the holes that the oil will flow through on its way to the pistons and de-burr their edges too. And if you can, jack up the line pressure with a shim or stronger spring. But don't say that I didn't warn you that you may not like the harder shifts after a while!!
@@AnotherWisenedOne I think furthermore, I could machine down the hat of the piston (elevated ridge that the cushion plate sits on).
@@AnotherWisenedOne Thank you! I was waiting for a reply like that! When you say add shim..u mean in the pressure valve lineup? How much are we talking here, like 1mm or more worth of shim?
Ivan WNY I couldn't tell you how much shim to add right off the top of my head because I have no idea of what the surface area of the pressure relief valve is or how much pressure the spring exerts upon it. So you'll just have to experiment with it to find what you like and can live with.

Hello Andy, I was wondering if it is at all possible to remove the shifter lever by removing the transmission pan, without having to remove the whole transmission? This in order to change the plastic shift lever bushing or grommet.
Is this possible or is this just a bad idea?
this is the plastic bushing on the lever outside the transmissionwhere the shifter link goes in?
Yes that nasty plastic bushing. Mine should be changed but unless I drop the transmission I may need to leave th old one in place
I noticed on your video that the shifter comes out of the Trans housing and thought maybe I could remove the pan and tehn remove the shifter rod, could be just opening up a whole can of worms though
@@Loco327654
Its a bit difficult but doable.
Just for info, there are 2 bushings, one on the shift tower lever and second on the transmission lever.
Its a very easy job if you have the correct tool, search www.mercedessource.com for info.
I managed to change mine without the tool, but it took some time and lots of swearing.
The one on the shift tower it not too difficult, theres enough room around to get the hands and sone tools in. The one on the transmission is difficult. So support transmission with a jack and remove bolts holding transmission mount to the chassis. Now tou can drop down the transmission a bir and also push it to the side to make more room.
If you find that its impossible to insert the bushing, you can cut it radialy. Now youll be able to insert bushing into the lever. Its hard to explain in words so if you need more details email me at aiptech1@gmail.com.
Andy when I get a moment I will email you, need some more explanation on cutting the thing radially
I have a C36 with a weak reverse - Do you have any suggestions of what could be the culprit?
Its the same transmission that I have. I suspect same problem
@@AndyPMercedesBenzChannel Thank you for getting back to me.
So it's doable... What are the tools required for the job? Do you have video of dropping the tranny? I'm considering rebuilding my 722.4 on w201. Thx a bunch
is it's doable . ua-cam.com/video/fQX9p67yLIM/v-deo.html this is the first video. Main thing is, google the rebuild manual , you gonna need it. Im not sure about 190 model, but for W202 i needed to use all my extensions to remove top 2 bolts and also had to tilt the engine+transmission to get access to them.

Hi, i have a 94 w124 with 722.4 transmission. It takes off with 1st and around 30 kph shifts directly to 3rd. I have no 2nd gear. There is no problem with other gears.It's been like this about 6 months. What might be its problem?
Hi, how do you know it shifts into 3 gear?
First i would check 2 vacuum lines going to the transmission, second check shift delay solenoid, make sure its not stuck in one position.
If these things are OK, drop and rebuild the valve body, check for broken spring on 2 gear spool
@@AndyPMercedesBenzChannel thanks for your reply. I know the rev- speed ratios and 2nd gear is missing for some time. It is same both upshifts and downshifts and alson on gear selector in "2".
By the way very very rarely it could shift to 2nd gear.
On the Pierre Hedary's channel he mentioned it could be k2 (it might be called b1) piston seal. Is that likely to be the problem? Thanks again, have a good day...
Can you post how to get the manual you have
google is your friend
just type on google 722.5 manual.
hi andy excellent info do you have a pdf manual Mercedes Benz Transmission Rebuild my trans is 722.423 same rebuiled info
thanks
Yes I do. I found it online, I'll see if I can find the link. If not send me your email, I'll send you a Google drive link.
any news ?

Здравствуйте подскажите на такой акпп пропала задняя скорость подскажите пожалуйста что делать?
Или другую коробку ставить или эту в ремонт.
I have trouble putting in the Planetaries into the Housing. As you said at 1:30:40. When I put mine in, it is level. Any hints?
check that the teflon seals to make sure the shaft assembly dropped into place, it might be hanging on the teflon seal
procarmanuals.com/pdf-online-mercedes-722-3-and-722-4-atsg-automatic-transmission-service-group/
Thanks for the manual, already found that due to other comments from you :) I'm pretty sure that the K2 Clutch is all the way down to be honest. I think I'll reassemble the planetaries again.
There is a bit of play in the planetaries if I'm pulling on the input shaft, is that normal? I think so...
I will test it again by only putting in the K2 and one site of the planetaries, so just the housing...
Sooo … still no success.
I even took the Teflon seals out. Is there a way I maybe can contact you directly ?

How long did it take you to remove transmission?
I can't remember exactly, but prepair to spent a saturday
AndyP Mercedes-Benz Channel i have changed out simple parts on my 1996 c280 but i think the transmission removal is beyond my skills i will probably pay to have it removed this is the most reliable best vehicle i ever owned with over 300k miles i for sure want to rebuild the transmission and enjoy this vehicle even longer thank you
@@ETHAN-fz8ec well this is not the beginner's job.
youll have to jack up the vehicle high enough off the ground and make sure that it's safe and secure. Next you have to drop the muffler off the hooks in the back of the car then you're going to have to remove the drive shaft. Then you going to need a really long extensions in order to get to the bolts holding the transmission to the engine. On the C280 engine it is somewhat difficult because the back of the engine is really close to the firewall. you have to drop the back of the transmission (tilt) low enough in order to reach top two bolts and you have to use almost four feet of extensions. You also might need a helper to help with your extensions to engage in the bolts head. for somebody who has a hoist and all the tools it's not such a difficult job, but for a diy mechanic its a JOB
Hello, my drive shaft doesnt move anymore After Assembly. Who knows a reason
Farid Bang
Check shifter lever position its probably in park position, the park pawl is engaged
AndyP Mercedes-Benz Channel i could move it until i have assembled the primary pump. During tighten the screws it makes an metallic noise in the Range of the backside of the transmission Housing. I have moved the shift level in every possible Position. But it still blocks...

Pull the tail off and check what you've done wrong

К1 барабан (722.3) не снимается с вала :( Что делать? Посоветуй пожалуйста.
По моему там стоит стопорное кольцо на валу. Мануал на трансмиссию есть?
@@AndyPMercedesBenzChannel Мануала нет. Но я смотрел множество ютуб разборов и ни в одном не видел, чтобы К1 барабан удерживался стопорным кольцом. Он снимается сразу после поршня реверса и должен свободно сниматься. Я думаю, я убил эту коробку. Когда снял масляный насос, то офигел от увиденного. Странно как она вообще ездила (коробка 722.369). Все пружины поршня реверса раздавлены раскромсаны на кругляши. Пластмассовые направляющие сплавились и обуглились, тормозная лента передняя -один металл, фрикционные диски -один металл и чёрного цвета, задняя тормозная лента -обуглилась, в поддоне глинообразной консистенции густой осадок тёмно серого цвета, кусочки металла, а масло чёрного цвета с запахом гари. Вобщем, пушной северный зверёк подкрался незаметно)))
@@biopump2000 да, ты прав. Должен свободно сниматься. Очевидно что-то попало во внутрь. Единственное, что можно сделать это трясти или резиновым молотоком,
Удивительно что она так долго ездила.
Очень полезное видео жаль что не русском
Пропадает задняя скорость и спинки появились особенно с1 на2 капиталить или частично можно
для начала проверь все ли вакуумные трубки идущие к трансмиссии на месте
AndyP Mercedes-Benz Channel добрый вечер .трубки первым делом проверил а вакуум какимнибуть образом влияет на заднюю скорость? Дело в том что задняя включается с задержкой 2секунды и теперь стала буксовать,то есть включаеш заднюю она трогается через 2секунды а если поддаш оборотов перестает ехать , в чем может быть дело?
нет...вакуум на включение задчей передачи не влияет, но ты писал что появились пинки при переключении передач, а это от модулятора в который идет вакуумная трубка....это отступление от темы
по твоему описанию ...это классический случай разрыва сальника/уплотнителя поршня включения задней передачи.
советую скинуть коробку как можно скорее и поменять 2 сальника на этом поршне, пока не спалил задние фрикционы. Может отделаешься легко, задний поршень в самом начале на крышке насоса и задние фрикционы тут-же доступны для инспекции.
Сборка смори на 46 минуте.
AndyP Mercedes-Benz Channel большое спасибо за совет так и предполагал а скажи пожалуйста на 1:46 минуте что это за клапан и для чего фишка эта с проводами служит
Эх если бы на русском было бы здорово
