- Опубликовано: 30 сен 2024
- This video shows what I had to do to get rid of a hard limp condition with codes p2602/P702 on a Mercedes c240 4matic. Conductor plate was replaced but it DID NOT resolve the issue. Solenoids ended up being the problem even though everything pointed to the conductor plate.
The conductor plate for this and other 722.6 vehicles:
amzn.to/2wgOl9I
The solenoid kit for all 722.6 transmissions:
amzn.to/2vi9SPw
The code reader I use, which works awesome on all vehicle models is:
amzn.to/2VyDOlc
I have the same issue valve body,transmission plate,soleinod all have replace but still in limp mood n when change to D n R the car jerking......please help me
Same problem boss😭 have you been able to solve it?
Same issue I’m having now
Has anyone ever told you you look a little like Anthony Hopkins?
Adem C
I’m having my friend for dinner
He does has similar accent as well
Lmao! First thing I thought. 😂.
Yes my dear
Thank you for the information, when I listen to bunch of those information, I will never buy Mercedes, even German car again. If you have a lot of money, you better poured them into the pacific. why no body talk about it because the car owner like show of and the mechanic can make more money. do you think Japanese car have those crazy problem? No! I have a Mercedes too, anytime I bring it to service, no one know how to repair except the very common problem, and no one will tell you the true, and paid $1000, because the Mechanical worker doesn't know Electronics, the Electronics worker doesn't know Software the Software worker doesn't know Mechanical and Electronics. Right now, all the car repair tech are cheater.
Imagine doing all of this on a E220CDI and its still in 2nd gear with turbine speed sensor fault code but nothing on the dash, then you realise that 2 injectors are not original and are from a later production car. You then i realised that the catalictic converter is original too adn when diesel injecors fail they spit out loads of fuel and it creates smoke and then it clogs up the cat. I cut that sucker off and beleave it or not car drives normaly.
I need a handy man like you
so your video is suggesting to change the whole transmission???!!😣
The 13 pin harness wire plug is only cliped not soldered i have tested 8 from old wrecked 1998 to 2002 ml320 found 1 ok rest had 1 to 2 wires loose thats was my problem i rewired on my 1998 ml320 and all ok now but was a nightmare to find
I have 2003 ML320 Sport 143K Miles on it, but my friend I tiered ESP key also it comes-up but still in Limp Mode, also the Conductor Plate issue for Mercedes on OBDII code is P0715. My car had the same problem leaking fluid tru the Transmission connector to TCM module-- I cant believe such a stupid so called German design liquid going upward against Newton's law of universal Gravitation.. LOL the insulation material sucks the OIL and releases it in the TCM .. what the F.. really!
Anyhow the code was P0715 which means "Speed Sensor Magnets" on Conductor plate failed, I changed the plate, basically went thru hell in my small garage with limited space and tools and finally did it.. But got real pissed that still was in Limp Mode,,. To begin with I first changed Connector to New One to the Transmission where the Tr-OIL Leak starts, then I cleaned the TCM, tried it still in Limp Mode. Changed TCM with the one bought from Junk-yard but it gave me an error and Limp Mode again plus OBDII said the "Gear Ratio Error" which programmed in junkyard TCM so it had different gear ratio. BTW: I electrically measured and checked the Transmission Oil and it IS NOT a Conductive Liquid OIL which means it does not damage the TCM electronically, to make sure I cleaned and tried my original TCM and worked fine but still in Limp Mode. I bought the Brand New Original "Mercedes ML320 Conductor Plate" for $220 from NAPA store. Anyone can help out there?
Dont buy tcm. Fix urself. So simple!! I have vidson it esp bas fix. Ecm fix rear and front sam unit fix. Easy. But solenoids. Remove test with 12v, and also change 13 pin plug
Thank you for all the info!
Thank you very much for your time and help in making this video! It was much-needed information on removal of the plate.
Hey Luke, hope you’re still active here. I have the same symptoms as you minus the same engine code and was stuck in limp mode. First I had the P0709 code I believe which was for the input sensor but when I went to change the tcm, it fixed the issue for an hour before going back into limp mode with a different code telling me the pulsating solenoid was bad. So I replaced the conductor plate and all my solenoids to no avail. Still in limp mode. Could it be my tcm again?
No it's the TCM that needs to have the computer board resolder
Great video - thanks for posting and i'm sure it will help me with my limp mode 🙂
Did you try to clear codes in trans and motor electronics and the drive it it should start shifting fine if its a conductor place and after 1 drive cycle the fault will return and shortly be back in limp mode
U got a nu conductor plate & didnt work. Next u get a used ML350 conductor plate & it works. So nu 1 is faulty?? Also thx 4 heads up on matching part # on TCU. I didn't do that on mine
I have c230 2004 in limp mode. Change plate mths ago it drives ok and today same problem
Selenoids?
You said that you turn the key and "Pressed the Button Winter or Sport on the side" and found out Limp mode works or Not? Where is that button? can you tell the name? Is it one of the Dash to the right side if the Key Buttons like ESP??
its by the gear shifter called "W S"
After watching your video I feel a little better about programming the conductor plate. My car did not give me any cod3s, but it does shift hard from 1st to 2nd when coldstar, but ones the car reaches a 180ﾟ it run smooth.
i really enjoyed your video. It was very informative and explained what i was wanting to know.
they need to put more unnessary chit on that trans
Hey Luke I have a 99 Mercedes Benz clk 320 and I changed the conductor plate because one of the the pins where the electoral plug, plugs into the conductor plate broke and it wouldn't shift out of first gear..... But I put a aftermarket conductor plate in and it still won't shift out of first gear..... Do u have a solution to this problem?
How did you fix that no shifting problem.
Hello Mr. Luke, this is Martin from Tanzania, can I have your whatsap number or email address, am experiencing the same problem in my mercedes Benz but mine does not give out any error codes in my OBD scanners..could it be the wires in transmission are bad?! Any help please.. I own Mercedes Benz w202, 1999
60k miles and its stuck in limp mode?!!
Clarise?
I replaced the conductor plate as well. Guess I'll have to replace those solenoids 😑
The code that comes up is p0763
Could have taken it to a professional mechanic rather than wasting your time and money
Lol that’s no better
HI Luke
I have a Mercedes C320 and it was in mint condition. My partner sold it to me to keep it in the family. I had it for about 6 months and it purred. When the indicator came on to service the car I went to a local mechanic and after it also just purred. He said I had an oil leak and did not have enough time to fix that so I had to make another appointment and came back 2 weeks later. As soon as I left my car has been shunting and even has stalled. I went back to him and he said it was not the transmission and said it was idling low. So he raised the revs by not much and while we took it for a drive for me to show him the problem it did shunt and shudder while he was there. It does not do it all the time but mainly when breaking on a hill or leaving the stop lights etc.
It still was shunting so I went to a transmission mechanic and he told me that it came up with this P2602 code. How can that happen after just an oil repair???
Do you have any advice? Much appreciated Jan
Sometimes trans fluid gets into the transmission connector plug...easy to replace ..
Thank you very much for your very informative video!!!
Would you happen to know what the solenoid readings should be or where to find the info? I also already changed the conductor plate and problem still persist, TCM looks clean so I don't think that's the problem so the only thing left are the solenoids
J M I If I remember correctly the resistance should be 2.5-6.5 ohms. You can check individually if you have them out or through the round plug. You can also apply 12 v to test operation. I found information here:
shop.ukrtrans.biz/wp-content/uploads/catalogs/722.6.pdf
Hate that they miss lead us
Do you think if you would have used the valve body with conductor plate and solenoids that your computer would have recognized the different setup or it would work with any 722.6 thanks for your video
Del Mytruelement not sure of what you are asking...if you have a whole spare setup then install it complete if you want, the valve body is not “coded” like the newer transmissions and does not need reprogramming.
Wow thank you so much I will be going to pick pull now that’s information that nobody’s given
When you opened the conductor plate and replaced it. You had to remove the solenoids, did you use the multimeter to check the voltage of each solenoids. That's the way to check the solenoids before you put back the conductor plate.
AmZ yes, checked the voltage and resistance and they were within spec. I also reinstalled the old solenoids with a new conductor plate and problem persisted. It’s not until I changed the solenoids with the junkyard ones that the problem went away.
Duh...
@@lukec4745 super fix. After putting in the new plate is all fine?
Also which brand 134 oil did you use? Did you drain the torque converter oil too? Total drain should be 7.25 liters.
what did you do to fix this issue
What is said in this video is NOT CORRECT!! I've had this issue several times, and the problem here is that his scan tool (I have the SAME one) is not good enough to reset the codes & hard limp condition. You need a "better" tool, like a Snap-On modis, or a STAR C3 (and up) multiplexer system, etc. The Launch Creader is OK for some things, but this is not one of them.
As for the reason why his limp mode resolved on it's own, well, I dont know...I think he simply just got lucky. Remember we are dealing with Y2K Era electronics, and they weren't all that sophisticated compared to those found on vehicles today. They sometimes (especially being 20+ years old now) get squirrelly and do weird things. Regards.
Johnathan Waters well if you can’t offer the solution then what is the sense of commenting. The car went to Mercedes after I put in the new conductor plate because I was told I need a “special” computer to reset the tcm. That is nonsense, the tcm will reset itself when the issue is resolved. The only transmissions that need the tcm flash are the newer 722.9.
@@lukec4745 Well, this is what I do for a living, and I believe I did offer the solution. Not sure what you're talking about.
@@lukec4745 First off thank you! ..Like to say Your thinking and way you explain things I can relate too and your camera shots were more than helpful..I have a 06 c230 and I believe I need to change my plug ..also I dont have a dipstick tube with a lock everyone keeps mentioning...stuck hours away with lil ones :(
Thanks. My c240 has the same issues. Changed everything but the solenoids. Do you think if I just brought brand new solenoids, it would solve the issues. I have P0730 code. Thanks
Hey did you fix it
Need other transmission!
You did a good job. I am messing with the same problem.
What does the transmission do?
You might replace the shift module...which is cheaper and easy job!!!
@@Dima-jq3mj it takes power from the engine and converts it via gears to make the wheels turn efficiently and smoothly.
Thanks I've got a valve body and adapter plug, and filter. Drained the transmission, replaced everything. The code Po700 was gone, But now I have codes of Po743/Po763/Po753. Torque converter
clutch and Shift solenoid C and shift solenoid A. I'm only getting reverse at this point. No Drive, 1,2,3, . I've check the transmission fluid and still only reverse. The car has 140 k miles and to

Thank you that plug is my problem its leaking and ots been acting wacky lights flickering on the dash and wont start so im gonna take the plug out replace with a new one and hopefully thatll fix the problem 🙂🤞
To catch all the oil. Get a plastic tray that's over sized to the pan. Catches all the oil when you drop the pan and place the pan in the plastic tray.
Been trying to get my W210 gearbox fixed, no luck.
If technicians that side are failing, then I have no chance here in Africa.
Pls help me out, my 2005 viano won't display PRND on the screen and my transmission won't select gear to second gear... Whenever I put on D or R it makes a hammering sound
Limp Mode ml350 i just turned my car uff and it fixed it but i wanna see whats wrong
Luke, i have been reading so many sites for information to a similar problem. You must have been very frustrated, as am I. Thank you for your diligence i found it very valuable as I am sure many other have. Thank you< Phil
Hello, can you please, please help me? I have a 04 C320 Mercedes. My car was doing the exact same problems you describe your car was doing. My car drive in 1st or 2nd gear ( it also was stuck in limp mode) it only drove up to 25-30 mph. My check engine light came on, I couldn’t go in reverse unless I turn my car off to change the gearshifts, it also jerked hard when shift in drive. The diagnostic verified only 1 code that the trans range circuit sensor went out/conductor. I forgot the numbers code. Nonetheless, I got my uncle to change it out today, however, it won’t move out of gears at all now. It's not even in limp mode (I don't know) My car won’t move at all now. 😭 Can you possible tell me what could’ve happened? What could it be now? 🤦♀️ I hope my question isn't stupid. 🤔
I've replaced the conductor plate and transmission on my 2000 Mercedes e320...my first transmission wouldn't shift...now this one will shift...but It still want accelerate...it go in p,d,n,r but it barely move when do and I have esp elec.stabil.prog visit workshop on my dash what yu think my problem...ppl sayin I ned 2 get a tcm
i solved my limp mode with a new battery and a reset.
Hey buddy what do you mean by reset the battery or computer?
@@deequan-nu5fy i heard an old battery can cause it. changed the battery then put a scanner over it and reset the codes using the scanner tool. changed all oil and filters, have not had a problems since
Thanks
Hi luke, I bought a 2000 E320 W210 wagon that had a bad transmission conductor plate. the guy i bought it from had messed with it and it was bad. I replaced the transmission with a transmission from a car I had been driving that works perfect. I put the transmission in place of the bad transmission but it is in limp mode. I know the transmission I put in it is good and now I am stumped? Where are the transmission codes logged? The transmission computer or the car ecm? Thank you patrick!
It’s been years since I did this video. I would check and make sure your tcm matches the transmission you put in. Also if the previous owner messed with the conductor plate then check the plug and pins to make sure that all of that is seated correctly. Otherwise I won’t be able to help in any other way.
How much that computer run u
JT 1200 eBay $65usd
good stuff explained well
Yeah quite awkward with that sketchy ramp.
thanks a lot jb
Change eps/abs box after that is working good luck.
Please can you swap the 722.6 transmission ecu from another car?
And is that going work without programming?
Thank you
Yes, I swapped them back and forth when I was troubleshooting and they plug and play.
Ciao ho il tuo stesso problema P2602 ! ! ! come hai risolto? Ho sostituito la piastra ma non ho risolto. Devo sostituire i solenoidi?
replaced conductor plate on a whim, wonders why codes till persist.
proper diagnosis is always needed. too many people condemn the conductor plate for the wrong codes. glad you got it fixed but please make sure next time you perform proper diagnosis, and you do need the proper scanner to erase codes from the tcm.
Benz-Tech Lou P. Lol this car sat at Mercedes for 3 days and they told me I needed a valve body. And yes, you need a special scanner which I have. Cheers
Sad but not all dealers have quality technicians, sorry that happened. Probably got a new guy that diagnosed your car. :(
I had same problems and more. Dealer wants to charge 300 for general scanning, then another 300 for the transmission issue. I told dealer to F... off!!!
I had the limp mode and a special mechanic wants 1500-2000 to change the conductor/solenoids (I did change the conductor plate). Then I ventured in buying a used shift module! 25 easy minutes and the problem gone!!!
I can help with mercedes diagnosis in the future.

Did u have any hard shifts before you did the conductor plate?
I’m driving an X156, a 722.9 automatic transmission box. I had a transmission malfunction notice on my instrumental cluster at 160000km. Car was still driving fine. I took it in for a transmission service. They changed the oil, filters and the gasket. Car came back still driving fine but the notification still comes up every now and then. Recently it triggered an engine light and when diagnosed it has no codes. I took the car back to the dealership & now they want to replace my conductor plate. The part is very expensive, my car is not on limp mode, gears shift fine as they supposed to I’m just irritated by the notification. Any idea what could be the cause? Please assist.
The 722.9 is a different transmission, from what I know the conductor plate is part of the valve body so an easy repair can no longer be done even though that transmission suffers from the same issue…engineering at its finest. Sorry can’t help.
Hi there I have a mercedes w211 E320 not shifting at all, I changed the transmission 2 time but still not shifting. All the rest funcion of the car are working fine...what to recommend me to do?
Check oil coms from wire harness to your electronic part
My 2012 Mercedes E350 overheated for just a second and I experienced a loss of power, but the engine still felt like it was running smooth, so I was happy to hear it may have went into limp mode. It's going to the mechanic tomorrow so we'll see. I parked it immediately and didn't restart it so I'm hoping like hell I didn't blow the engine. The car was from Florida and I'm in Maine. It was 17 degrees when all of this happened. I opened the hood and you could see spray on the engine cover. Care to speculate? Thanks
I also replaced the conductor plate along with the electrical connector, fluid, filter, gasket. And it worked initially for about 30mins. Then it went back to limp mode , but also it would no longer accelerate (in drive or reverse) as if it was stuck in neutral. The solenoids looked pitted when I dropped the valve body but only tested resistance and they checked out fine. I’m thinking solenoids need to be changed , but do you think it could be something else as well? Given that when it’s cold, it’ll shift but once it warms up , it will not accelerate in drive or reverse .
Change the transmission oil in the filter
G 463, 1997, TD, the Mercedes mechanic has replaced the selenoy and body valve and the shifter. when we put the speed arm on the D, there is a delay of 5 seconds before doing the speed D. where is the problem? the mechanic thinks that the body valve is defective and replaces it with a new one. What do you think?
Your mechanic may be right but You can try searching your symptom online as it’s possible one of the springs in the valve body is broken, it’s also a common issue. There are kits you can install to tighten that up, they are very inexpensive and worth a try before purchasing a pricey valve body.
In my case I did the required job changing the conductor plate brand new and all the solendoids brand new but yet the car is still in limp mode!!! Any suggestions? 😧
u need to buy a obd2 scanner and reset the tcm look up more videos youll see
my cars in limp mode hopefully after i reset it and change plate its fixed
Thaks a lot!! Indeed, no computer needed to reset!
Thank you for being honest about other peoples input
Nice informations
Where do you change the solenoid ? I mean its location
Ta Oh solenoids are mounted on the valve body along with the conductor plate.
Luke C ok Thanks
I only change the plug on the transmission, does the conductor plate, easy to remove ?
Ta Oh you have to remove transmission pan and then the valve body
...what about you become a consultant for a fee....
Never seen those wheels before.
Great video Bro!!!!
I have this same problem now
So I guess I’m not going too get one
4:40 you mean tcm or tcu?
2001 e430 fell into limp node and hard shift. Changed plug, conductor plate and replaced TCU with matchng numbers. The car will shift fine until I get back to a complete stop. Then gets back to limp mode until I restart it. Eventually the p0700 code pops up again. Everytime I erase the code this whole process restarts.
Any updates on this ? How’d you fix it ?
@@swishmar0308 sold the car to my neighbour.
Will this work on my B150 auto? 🤔 its in limp mode 😣
Get a rebuilt valve body. The springs can break and the valves can stick. Then it won't shift
Why would you need a rebuilt valve body? It’s expensive. If you watch the video I think I mention I bought the rebuilt/shift kit for it, quite simple to change those springs. None of mine were broken but since I bought the kit I replaced them anyway. Wasn’t the problem.
@@lukec4745 Sounds like we had different issues. I had a very difficult time with a 1997 280c that was stuck in 1st gear. Your video was very encouraging. In the end, I went with a rebuilt valve body by Sonnax. I believe it had all the solenoids on the part for around $450-500 with a 1year warrentee. A bit expensive, but it did the job.
Mine is still broken
Great Job ! Would you still recommend buying one ? I like the supercharged motor also both are great !
You can buy my 2095 c230k!!
@@ericthompson4644 Scotty Kilmer was right ! Toyota is the best ! No disrespect.
I replaced my conductor plate and same issue it’s stick in 3 rd gear and engine check light , I have not checked codes cause I don’t know how , should I try solenoids
Hunter Mclaughlin always check codes first, it’s easy, there are a lot of videos on the subject. Even a cheap reader from a parts store will be better than nothing.
You need a scan tool to access the transmission computer and reset it afterwards you should be good after that
If a true limp mode was trigger by the TCM, a reset and clearing of all TCM DTC codes is needed. The other solution to the limp mode is, after the fix, is to change the TCM. This will only work on NAG 1 5 speed. NAG 2 7 speed is a completely different headache.
Thanks.
Thank you very helpful!
Good job
Hi Luke and thank you for the video, I replaced the connector, conductor plate without changing the selanoids, filter and gasket and the car is on Limp Mode with hard clutch sound when I shift from P to D or R.
I went to clear all the codes that I had
P0715 Input/Turbine Speed Sensor Circuit Malfunction
P0753 Shift Solenoid A Electrical
P0758 Shift Solenoid B Electrical
P0763 Shift Solenoid C Electrical
P0720 Output Speed Sensor Circuit Malfunction
On a regular scanner not a MB , any thoughts?
What scanner did you use to clear the codes?
Look at the TCM. It must be covered in oil from the O ring 13pin plug. Yes it can go trough the harnes and fill that boi up. If it foesnt work that your cunducter plate is bad
So you didn't have to reprogram the conductor plate?
No. Not on the 722.6

Hey Luke, I spilled a can of soda into the middle console of my 2000 CLK430 I started wiping fast but almost immediately my car went into limp mode and I MAY have smelled a small buurning. Pulled over put car in Park and it was stuck...left it overnight, came back start the car and did a shift OVERRIDE to get it home but the tranny doesnt shit gears...there are no codes or illuminations on the dash tho, any ideas?
DaRealist One the can of soda might have fried your shift module, it’s a different issue. Google Mercedes shift module.
How do you know that you don't have any codes? What diagnostic tool did you use to determine that?
Thanks! Shift module was the issue....I replaced it myself
Same thing, I spilled coffee and it went into limp mode. I replaced the conductor plate - no help. Lived with it for 2 years then I changed the shift module. It works perfectly then!!!
You need shifter
actually if you realize, your video did not really give an accurate solution to the limp mode problem. You just bought another transmission and your limp mode was gone! So are you saying the problem is the whole transmission???
Thanks
I encountered that before on my 2000 CL500 all I did was replaced the conductor plate and fixed the limp mode issue. You probably got a bad conductor plate.
Rey Bolor I tried 2 conductor plates.
hey does the car make a whinining nosise when you drive it if the conductor plate is bad. My e320 whines then goes out of gear.
O Dogg I had no whining noise. That could mean something mechanical.
I changed fluid, filter, gasket and harness connector..problem solved
@@odogg4447
Whining mean low fluid level. You didn't have enough transmission fluid in it.
Luke C, I found this video to be extremely helpful. I just bought yesterday a USA 1998 C280. It is stuck in first gear. Car shows 230,000 miles on the odometer. When you go from Park into Reverse, or Park into Drive there is a very strong lurch. The car jolts into gear. It will not shift out of first in Drive or if I shift the automatic trans manually. The seller (not very car intelligent) gave me a new trans. dipstick, and the fluid measures a little bit low, but seems like clean fluid. I will guess I need a new Conductor Plate and Solenoids, but I don't know. Online there are many refurbished solenoids available. I wonder if they are reliable? Any suggestions on where I should start, as I feel badly that it took you a month to solve yours. Thanks for your great video, which is very helpful.
Jon Randall scan it first. Also check the TCM module under the passenger footrest for transmission fluid contamination. If there is fluid in the connectors you can try cleaning the harness and installing a new connector on the transmission, cheap fix. Google 722.6 transmission connector.
Hi Luke. Thanks for your reply. The scan reveals code P0715 ( Input / Turbine Speed Sensor A circuit ). This input speed sensor is built into the Trans. Conductor Plate which I have just replaced with the OE German Conductor Plate. I, of course, replaced the Connector too, and noted that the wiring had trans. fluid on the harness. This lead me into the passenger foot kick panel, and I removed the Trans. Control module, which had small fluid on the wiring going into the connections, and into the TCM itself. I opened the TCM carefully, and other than a little bit of fluid inside near the connectors, it appeared in good shape. My car is stuck in first or second gear, and won't shift into other gears. I can reach 30 or 35 but the tach is at 4500 approx. I am not sure if this is "Limp Mode" or not. I am guessing that I need to have my TCM rebuilt or replaced, or Conductor Plate solenoids are actually bad. However, one parts place thinks maybe the Input Speed Sensor Code P0715 is in German terms ( = shift micro switch ), which in English is Neutral Safety Switch.
Jon Randall did you resolve this issue?
@Steve Johnson
I did have the same scan code, but I just replaced the shift module and it works right away. Good lucks. Shift module normally do not last long since ppl spilled liquid and the heat...etc.
Recently my transmission did not go OVERDRIVE (waste of momentum/gas)
then the vacuum hose to brake booster broken, I replaced it and also replace a big vacuum hose which is hardened by heat and was loose. Now transmission runs good!!!
I have the same problem on renault laguna.
So your problem was the celluloid ?

Dimitriy Perchik I have a GL450 and I’ve got the 722.9 transmission. I know it’s in first because of the speed and rpms that it will top out at. I’m pretty sure it’s my conductor plate that’s bad. More specifically the speed sensor. Could be a solenoid issue as well. From all of the info I’ve been reading I can’t just buy one or go to s junk yard for one I can only get mine refurbished. Unless I want to spend the THOUSANDS at the “stealership”.
Dimitriy Perchik and yes check engine is on. And the error code it’s giving me is pointing the speed sensor. Thanks
@@laenaszone
What is the top speed you can do with limp mode on? If you have tried to drive it like that...
If you had a scanner simular to Icarsoft MB 2 or Icarsoft MB V2, you could go in the TCM and clear the code for the limp mode and drive it until the limp will comes back.
My understanding with these transmissions is, base on my experience with them, if you are able to clear the codes and drive for a little while, it means that the problem is more likely electric, but if you try to clear the codes and they don't clear or do anything, and you are not able to drive after clearing/resetting, it means that the problem is more likely mechanical. For example, a solenoid can get the right voltage and have the right resistance, but if it doesn't open and close (mechanical process) when needed, your transmission will not operate properly.
You are right about NAG 2 7 speed transmission. The TCM is part of the conductors plate and it does require SCN (Security Code Number) coding with the immobilizer, just like the ignition switch, key, steering lock and instrument cluster. The cheapest option for you is to fix/refurbish the original that you have.
You can buy a used one, IF you can find someone to make the conductors plate virgin and after personalize (SCN Coding) it to your vehicle. The Chinese copy of AVDI, the FVDI system is able to make the plate virgin, but to personalize it to your vehicle, it will require a DAS Xentry diagnostic system or Vediamo, or Autell system that can do SCN coding, or AVDI.
laenaszone are you sure it’s first gear?

Ant Be mobbin I can’t comment unless we have somewhere to start with...some background is needed, there can be a few reasons for this. Get it scanned first, with a descent scanner so you can get all the codes not just generic ones. Make sure your battery is fully charged.
Hey Luke, when you have that limp mode problem, did the fuse #55 burn out?
I got the same year and model you have, with no crank no start problem.
I did it in the road and on a hillside not a good thing to do good video Ed uk
