Mercedes 7G 722.9 TCM Speed Sensor Fix P2767 Y3/8n2

[@godly8320]

Thanks for the information I’ve bought 2 Mercedes with the same issue this will help me out big time

[@persianchris2451]

Just some friendly suggestions and this is totally in MY opinion... 1) To the watchers of this video: I recommend everybody sets Playback Speed to at least 1.5 2) To the creater(s) of this video: I recommend when you are using an impact tool and it's making noise, you consider maybe not speaking during all that sound since you're not as audible and the frequencies of that impact sound cuts right through your voice, thus making it hard to understand what you're saying

[@aljar2010]

Hi friend, thank you for your video. I have a similar problem meaning after the diagnostic on the mb, I have this code 2734; The internal electrical check of component Y3/8y3(K2 clutch control solenoid valve VGS) has failed. How can you advise in this kind of situation. Best regards,

[@G-MansWorld]

Can't advise anything but u can try to replace the sensors that worked for me. I also believe you can buy the whole conductor plate ( aftermarket) for way cheaper than years ago.

Hi thank you for sharing this video. I was wondering if you can tell me where the temperature sensor is located on the transmission. i got the same transmission. i got p2740 error code but no check engine light and the transmission shifts fine too but want to address it before anything catastrophic happens. Any information of the location of the sensor is greatly appreciated!

[@richardvalach3353]

Hello, great video. I have a problem with my gearbox 724003, sometimes it throws neutral - message without changing gear while learning to shift with diagnostics, the transmission stopped shifting completely - no EEPROM backup in diag it has 0 value y3/12s6 pressure distributor position sensor - do you know where it is located in ehs? or is it necessary to replace the complete ehs? You will help me a lot, I will be very grateful for any advice 🙏

[@G-MansWorld]

@@richardvalach3353 I don't think you need the whole valve body your problem sounds more like the conductor plate only. Those days they are cheap but you will need to code them or get it coded to the VIN as far I remember.

How is it now. One thing concerning, it's been repeated not use a magnet for cleaning solenoid screens, to dip in fresh fluid over and over to clean. If you're trans is still good, makes one wonder about that warning. How did you reattach connector to new sensor?

[@angelmisaelelias]

Tanks for the video, Only One question. When you chance the sesors you need reprograming the TCM module to reconice it?

[@G-MansWorld]

No you do not need to program

[@markjones8632]

I was told that you have to re program the transmission control module after installation of the output sensor. Is this true?

[@G-MansWorld]

Not that I remember the only time you need programming is when you replace the conductor plate because of immobilizer. You might like to do an adaptation but I don't think that even this is needed. Of course you need a scan tool to erase remaining codes the battery disconnect might not work.

[@markjones8632]

@@G-MansWorld I am replacing the conductor plate just like in your video. So I can just replace the plate and then drive to a shop to erace the codes and i will be good?

[@G-MansWorld]

@markjones8632 I did not replace the conductor plate I only replaced a sensor on the conductor plate that's why no programming is required if you replace the whole board than you need programming car won't start

You use the special punch tool to cut it out of the epoxy but some tools are kind a soft try to buy one that is decent quality

[@G-MansWorld]

remember to support the sensor from the bottom to avoid destroying the housing

Nice bro! it felt really relaxing watching this. Do you know if y3/8s1 is repairable? It has a p0705 code is the range selector for PRDN

[@G-MansWorld]

I do not know it's also a long time ago when I did this fix. Sorry can't help you out here but range selector solenoid should be possible to fix. On the other hand those conductor plates are not that expensive anymore.

What software do you use to read your transmission codes? Would it work on a 2011 E350?

We have Autel maxi in the shop but you don't need anything super fancy a Bluetooth dongle and some android software for MB should be ok to get codes out of the TCM or ECU good luck 🤞

This is a very informative video and provides enough visual facts for the brave DIY mechanic to do a repair. Well done. I'm going to replace sensor Y3/8n1 when the replacement one arrives in the mail. When you re-assembled the unit, what torque settings did you use to tighten: a) the 7 control unit bolts to valve body, and b) the 4 bolts securing the solenoids? It would be a great help to me if you could let me know, as I can't find that information anywhere.

I have a 2007 s550 giving me codes p2767 & p0717. The car has a few bumps when shifting if i am flooring the car but not when cruising, sometimes when cruising the car will lose acceleration as if it were going limp and running at about 10% capacity and then it open back up again completely, any thoughts?

[@G-MansWorld]

Sorry can't really help in this case

[@Oldmanriverman]

Thanks for sharing! I am geeting codes 0730 /2505 / 2502 My next step is to drop the valve body and plate to look for for debris at the K1 solenoid. I have gears R - D1 - D2 and then nothing when it attempt to shift to 3rd. Per the 722.9 chat it is at this time that the K1 solenoid is to be activated so I am going to look for related issues there. Have you and is it safe to put 12V to the solenoid to confirm actuation?

should be not a problem

@@G-MansWorld Thanks. I found this piece of information in a forum but the image of the port layout wasn't accessible.

This is such a fukin horrible repair to do I did this repair on families car a couple years ago (BOTH SENSORS ONE IS EASY ONE IS HARD AS YOU SAY). Knocking out those sensors is no joke. hard to do without damaging the flexible circuit and other stuff. I ended up epoxying the long difficult to remove sensor back in there as I had damaged the plastic on the hard one closest to the computer. The other one beside it was easy to get out as you show. Next time (I hope theres not a next time) I'll have to try you're method. I used a supplied drift/cutter on the short sensor but the long one was super hard to get out. Car was working fine after the repair but I wouldnt feel comfortable charging people to do this I only do it for family.

[@michaljezek4930]

Are you serious about this?! He's hammering it! It won't clean it of oil (that's why there isn't even how to solder the sensor back). This tickling of the solenoid with a magnet will certainly not remove the chips, certainly not with this, it is weak. And at the end does he tighten the screws by feel?? Another tinkerer.

[@G-MansWorld]

Yes that's the only way to get them out and it works just fine as long u support the other side with a socket basic mechanic stuff. I fixed lots of transmissions and rebuild some best part is they did shift fine after installation. The solenoids have screens on them the metal dust if any collects on the screen you won't need a super strong magnet but a neodymium magnet is pretty strong and works well. There is even Mercedes service instructions out there who tell you to do just that. All that matter on the end is if it works for you final result was ok I am happy. You can buy the whole board if you not comfortable with it but imobilizer is in it if I remember right so need programming.

This brute-force approach could damage other components. I found that there are other videos that show a special punch that cuts around the sensor and pulls it out. I suggest you search for those. To the creator: Also look for those videos so that you can level-up your approach. The video is informative but I would never bang on electronics like this. No, I'm not a mechanic, just a tech-savvy bass player with only one W-211.

[@G-MansWorld]

It's a hole punch it comes in the set and you need to punch quiet heavy no way around it and some versions have a even stronger epoxy ..... So yeah I suggest to you to try it out your self and than come back and give me your opinion on how easy or not easy it actually is to get them out. But today u actually can buy the whole conductor plate for pretty cheap like 200 ish dollars almost not worth the hassle anymore.

[@BMAcon]

I completed the repair of the y38n2 sensor and the car drove ok for about 70 miles and now I am getting the same error on the scanner and the transmission is back in limp mode. I am thinking I need to replace the conductor plate at this point??? It's vgs2 so I can do just the conductor plate. On ebay I can buy one that is ready to pair to the vehicle and preprogrammed to my Vin, but what else do I have to do to make it work with my car?
