HTML-код
- Опубликовано: 27 июл 2024
- This Benz is stuck in LIMP mode and won't go faster than 30 mph! This is actually a common issue and an easy repair for these cars. In today's video I'll be replacing the transmission conductor plate on this 2000 Mercedes C230k with the 4-speed automatic 722.6 transmission. These transmissions can actually be very reliable and cheap to maintain. Even this repair really didn't cost too much.
This repair is the same for all C-Class, E-Class, M-Class, S-Class, SL-Class, & Sprinter from '97 to '14.

Please note that working on the transmission requires mechanical expertise, and it is recommended to consult a professional or refer to the vehicle's service manual for detailed instructions. Nevertheless, here is a general step-by-step guide:
Note: Ensure you have the necessary tools, a replacement conductor plate compatible with your vehicle, and a clean working area before starting the procedure.
1. Park the car on a level surface and engage the parking brake.
2. Disconnect the negative terminal of the battery to prevent any electrical mishaps during the process.
3. Safely raise the vehicle using a jack and secure it with jack stands.
4. Locate the transmission conductor plate. It is situated on the top of the transmission, underneath the transmission oil pan.
5. Drain the transmission fluid. Then remove the transmission oil pan. This typically involves removing bolts around the pan's perimeter.
6. With the pan removed, locate the conductor plate. It will be attached to the valve body.
7. Disconnect the electrical connector from the conductor plate.
8. Remove the bolts securing the conductor plate to the valve body. Keep track of the location and order of the bolts, as they may vary.
9. Gently lift the old conductor plate out of the valve body.
10. Clean the valve body thoroughly to remove any debris or dirt that may have accumulated.
11. Take the new conductor plate and align it with the valve body. Ensure it is positioned correctly before proceeding.
12. Secure the new conductor plate in place by tightening the bolts according to the manufacturer's specifications. Use a torque wrench if necessary.
13. Reconnect the electrical connector to the conductor plate, ensuring it is properly seated and secured.
14. Reinstall the transmission oil pan, making sure to use a new gasket.
15. Start the car. Refill the transmission with the appropriate amount and type of transmission fluid as specified by the manufacturer.
16. Lower the vehicle from the jack stands and remove the jack.
17. Reconnect the negative terminal of the battery.
18. Hook up OBD Scanner to the 38-pin connector and reset the fault codes in the TCU (transmission control module)
19. Start the engine and check for any transmission-related issues or warning lights.
20. Take the vehicle for a test drive to ensure the transmission is functioning properly.
21. Check fluid level after test drive. Adjust if needed.

Hello I have a question, i changed the plate in the transmission 722.6 and I bought a icarsoft scanner and the adapter, yes it took it outa limp mode and it's changing gears smooth, but the check engine transmission code keeps coming back, what do you think??
@worldwidesports4k did you clean the connecting harness really good?
@@Mechani_Cole yes I did.
@@Mechani_Cole I started the car this morning the check engine and code went away, thanks for your help .
This is the most helpful video I found on doing this. So thank you very much for putting the time in to make this process nearly dummy proof.
Congratulations good job, from Africa
Good job
Honestly you'd be spending the same/more to have a shop reset the codes for you, so even using that scanner this one time already pays for itself! I've been meaning to buy one myself, but for now I'll just annoy my friends to borrow theirs lol
Agreed!
W211 e class gearbox in limp mode fault codes p220a p2500 p2001 what is the problem
Probably the same thing. The conductor plate is likely bad
I have to add the Mercedes update to my icarsoft v2 tool. There’s 5 options, what’s the difference between MB and M900?
Good question! Let me knownif you find out
Will this work on my 98 e430 turbine sensation circuit a is what the engine code came up as??
Yeah, most likely. As long as you have the correct computer to reset the codes after. A regular scanner doesn't work. On the valve body (in your transmission) you will find a plastic plate, which carries the input and output speed sensors. This plate is known to crack around the input speed sensor. Hence your problem and the lock down in second gear. The repair for this means removing the tranny fluid/oil pan/filter/valve body and lastly the electronics plate. Then replace the plate, and refit all other parts. Hope this gives you a starting point🫡
I have P0741 code on my gearbox oil was really bad so i change it now looks better but do i need also to change this plate, because torque converter is fine gearbox is shifting smoothly no weird noise no nothing so i don't know what the issue can be
Either way, you need the proper scanner and adapter to reset the code. It won't reset on its own
My reverse lights dont work is there a switch in here ? im stuck in low gear also the car is a 2000 with a 1999 filter and brown fluid
Check fuses or bulbs first if both aren't working. Will need to do a reset after the repair to get it out of Limp Mode
I did the same replacement and my 2000 c280 and it’s still in limp mode. I bought a different Mercedes diagnostics reader to clear the TCM codes and it had every Mercedes listed as a car option but my 2000 C280 will that reader have the 2000 c280 as an option? I couldn’t even get to the part where I read the tcm because my car wasn’t listed please help!!!
I'd use the scanner I have linked in the video description. I still use this scanner all the time, works great for these years
Will the icarsoft MB 2.0 fix the same issue? Are they easy to setup?
You have to repair your car first before using the scan tool
I have a 2005 e350 4matic ... Is it absolutely necessary to replace the conductor plate every time or can the tcm be reset without doing that just to get it out of limp mode ?? Basically I'm just asking if it can be done without having to tear it down ??
Always try a reset first, sometimes it works if you have the proper scan tool. Then if that doesn't work, more work is needed
Thanks for the fast reply .. and lol I didn't realize that like twenty other people had the same question as me ... Limp home mode sucks man thanks for the input tho ...
@user-tp7ys7pp5v limp mode sucks the older you get too🥲😅
But for real, I keep a scanner in my Mercedes and Audi just in case it ever decides to go into limp mode. More often then not, you can reset the computer and get home at least
Hello
Do I need to do the program after replacing the conductor plate with a new one, or do I already have the program in the new conductor plate
What should I do if I have to do a program?
No programming needed as far as I know. But you do need the correct scanner to be able to access the transmission control module for the reset to get to rid of the code and get it out of limp mode.
2005 Mercedes Ben e320 change the conductor plate after that didn’t want move no more or shift can can this scanner help take out limp mode the one that you post .
@alejandrorodriguez3617 yes. As long as there isnt an issue still
@@Mechani_Cole I had use icarsoft cr pro or I can use any icarsoft
@alejandrorodriguez3617 has to be Mercedes-Benz compatible
Where did you purchase your plastic assembly from?
Not sure what you are referring to. Everything I used should be listed on the description or the pinned comment.
Hello i have a question, i have your exact same scanner as yourself and it wont connect to my 2000 mercedes e 320 its saying link error do you have any ideas why is that? Key on, plug in under hood. thank you.
Good question! Double check for bad fuses or loose pins. Can check the pins with a small tack or something to see if they are grabbing
@@Mechani_Cole ok. let me get back with you. man we just had a tornado in Houston texas, I don't have lights and my phone is about to die. I get back thank you dude.
Did you try the Icarsoft through the inside port ?
Yes. TCU can't be accessed through the OBD port inside though.
Are you still happy with that scanner or have you moved on to something better thanks
Still happy. It's a great scanner. I have a few others, but this is my main one besides using VCDS for Audis
What are you saying odd2 pin connection
Under the hood there is a 38 pin connector to hook up an obd scanner to that connector. You need the adapter listed in the description
Great video. After replaced the transmission conductor plate, is the car needs to reset the programs?
Yes, it needs to be reset with the proper scan tool. Link in description for everything needed
Would this scanner work on a 2000 CLK 320 ??
@juanflores2449 yes 100%
@@Mechani_Cole I have got the MB v.2 and it saying it doesn’t support my system I don’t want to spend no more money on this beautiful car your a life saver if this really works i have replaced the conductor plate and not it does not drive or reverse why is that?
@juanflores2449 are you using the 38-pin connector? It won't work without that part to access the TCU. So it won't shift until it gets reset properly
My car drived but it didn't shift out of first gear.Change a conductor plate but now the car will not drive at all.Is that because it needs scan
Yes. You HAVE to reset it with a proper scanner through the box under the hood with the 38 pin connector. You can not just change the part and have it be fixed. The computer must be able to access the TCU module to send the command
Thank you so much.The car still jacked up.I put it into gear, but the wheels will not spin so that is a sign.It's in limp mode
@pierreperk7079 yes. It 100% needs to be reset with a proper scanner
@@Mechani_Cole thanks you so much .iam in California
Sorry, have one more question.Is it possible that I could have that lever in the wrong place where it connects to the shifting rod
Would this work on a 2000 clk 320 ??
yes
Yes
How much fluid and what’s the labor
Hours for this job
Took me about 2-3 hours max, but I was taking my time and taking breaks. The fluid depends on how much comes out. But either way, have to adjust the fluid level according to the dipstick. Hard to say an exact amount on transmissions
@@Mechani_Cole how many quarts did you buy
@TheArmedMechanic just a 5qt jug. Don't even think I used it all either
@@Mechani_Cole okay thank you
@@Mechani_Cole do you remember the type of fluid
❤
Points to fuel door... Got the chromed license plate here. XD That is def wayyyyy too much chrome lol. Vomit inducing.
Took all that hideous chrome off right away🫡
