Mercedes Benz Transmission Reset

How to put an Adaptive Transmission into Relearn Mode

[@josetrejo3183]

First of all I want to thank you for your lifesaving tip. It happened to me tonight, I'm 73 years old, can barely walk, half deaf, can see well at night (I still can drive) and I'm broke. Well, tonight while on an errant the car stop shifting gears, then the devil whispered in my ear, "you can find your answer in KZbin and boom, there you are with this exelente video, I tried and CHEETOS it works, the tip works, so I saved the money that I don't have, the car running nice and smooth and I'm happy as a dog with two tails. Again thanks for your tip.

[@A_Renaissance_Man]

Excellent. You are the reason these videos are made.

[@DrMathOfficial]

So you receive this beautiful help and gift....and you thank/ credit THE DEVIL?!?! My friend, please give the credit to where it truly is deserved, GOD and Jesus Christ. Furthermore, you better HOPE and pray 5hstvit wasn't really the devil that helped, because he doesn't help without 😭 requiring (and coming back to collect), an infinitely undesirable cost/ compensation.

I've had every luxury Barn on wheels including RR, Bentleys, 7series of every generation and a s65 and s63....and my 03' s600 is the finest Sedan I've ever had. W220 was the best sclass ever !

[@josetrejo3183]

Dr math, thanks for your advice, the truth is I really thank the guy that made the video, about the devil whispered in my ear that is only a colloquial expression. About God, well at my 74 years of age I'm still debating, most sure I can tell you that I don't believe on your god, if you want to know I tell you; I believe in Spinoza's God and he doesn't make miracles or needs praying.

[@KB-zq9ck]

One other thing about the check engine light. A bad fuel filler cap, will cause a check engine light to come on. The gas caps rubber gasket might not be sealing the filler tube so the tank wont be under pressure and cause the check engine light to come on. "If your engine light keeps coming on that is'. And if not your problem my reply is to maybe help another with the check engine light.

How do u do transmission oil change on tat car just got one would like to do a transmission oil change on it

[@paulmcmanus9603]

I had a car scare on my E320 W210. First, I stopped at a light, and when I pressed the accelerator to go, the engine revved up and seem like it was stuck in 4th gear but I limped to the nearest parking lot (no first gear ). I worked the gearshift to reverse then drive then park for a bit. Put car in drive BUT it would not switch to 2nd gear....so I was close to home luckily. Drove rest of way home in first gear. Remembered something about a transmission reset from 4 or 5 years ago. I found this blog and decided to try a reset. Hooray! It worked. Took the E320 out for a test drive, and the transmission shifted through all gears very smoothly. The reset took all of 5 minutes. If I had taken the car to the Mercedes dealership for service, I can guarantee that they would have charged probably $300.

Hey guys I'm i live in England , anyway I drove to Birmingham from my destination and back 150 miles and I juddered all the way I've done what you said and bingo its reset thank you so much

[@A_Renaissance_Man]

Thank you very much for taking the time to comment. I really appreciate your input.

[@HzPjtvHYom4991]

The way I understood it was (and I may be wrong, I don't know a ton about this) but that the transmission is in adaptive learning continuously. Meaning, it is essentially "learning" all of the time anyway. It should 'adapt' to your driving habits over time. However, what this does is kind of reset that learning "data set", so to speak, which kind of accelerates the smoothing out of the transmission, opposed to waiting for it to catch up. So, it's not that the transmission stops learning at a point, it's that the input data gathered is cleared and has no further affect on your the current condition of the transmission. This is why they say that it needs a number of shifts (I've heard 40 too) because there needs to be 'some' input data to adapt to. Further recommendation would be to drive it for a little while after you reset it according to your typical driving pattern. I believe that's why you say that it gets better over time, because the data set becomes more averaged and gets closer and closer to your driving style. If your driving style changes from month to month or week to week, then resetting is where you'll notice the most difference. Anyway, that's kind of what I gathered from a non-technical background. :)

[@TheEpyheart]

I was feard when my W211 start jerking during slow acceleration... here i am and will do what you adviced.. thank you for your sharing... love from Singapore

[@A_Renaissance_Man]

Unfortunately, diagnostics for afar is extremally difficult. What you describe sounds like an engine problem. The easy fix could be spark plugs but an inspection before the work is done would be the best thing to do. The transmission is notorious for fluid to leak into the electrical connection and causing problems like you describe. I hope the repair turns out to be something simple like I described.

After having the the transmission lines replaced yesterday on our ML320 we noticed the rpms would not adjust down to a normal rate when driving on the freeway. The repair shop found your video post and it did the trick. A day later and it's doing the same and also dropping out of gear on road travel. We're like to shifting into 4 and 3 drive settings to slow the down when approaching stops. Should we NOT do this until the car relearns?

[@orfeosmania8606]

I have a ML 320 CDI W 164 and it has the same gear system... what surprise me is that it is true, if you stay in highway for a little while and then you go in the traffic the shifting is not matching your need... I was thinking that MB should have switch on which youselect what type of behavior you want... AUDI it does.. MB just keep the adaptive mode of the previously drive mode... quite strange... anyway... MB didn't learn nothing from the long history and I have find out that all the cars with 7G has the same problem.. .good luck to all of us

Seen a couple of other videos on the subject and everyone says that after removing the key, do NOT do anything for a few minutes - no opening doors, turning on anything - just stay put for a few minutes. Also no one has suggested to repeat the exercise every so often. Really confused now - help !!!! Can it be done even if there are no obvious signs of transmission mis-behaviour?

[@A_Renaissance_Man]

Thank you for your comment. Of course, this will cause no issues if you do not have shifting problems. This puts the transmission in relearn mode not reset - if there is such a thing. I think that waiting in the car is a bit much. Without MB Star to prove it, my opinion is that opening the door, getting out, and closing the door does not prevent blanking the shift history for a relearn as I am quite sure this works for me and I get out of the car all the time after performing this procedure..

[@KB-zq9ck]

I don't know why this guy say "Relearn mode" It sets the trans back to factory default like the day it drove off the manufacturing floor. So it is a reset. So...being an adaptive driving style transmission of course it will learn how it is driven.

This procedure sets the transmisdion into relearn mode. The procedure is also one that will not cause any problems if it does not work.

Older Mercedes transmissions are not meant to shift smooth. If you don’t feel a slight kick during shifts, your transmission can burn up.

I need to find this out also.. there are adjustments. 3 to b exact. 1 on the linkage, 2 there is a small key at the transmission that u can turn to soften or harden the shifting/torque. And 3 on the ignition pump of the diesel there is an adjustment also..not sure if gas has a similar resolution... the kick down switch can get dirty n b in an more aggressive state..clean and lubricating helps .plus at the transmission the kick down there should get the same treatment...

I did this and it does work

[@geoffreycarbone2647]

So what if my accelerator never clicks, even when I push it to the floor? I don’t think mine has a button.

Hummm ... I don't know how to help you if you don't have a down shift button a.k.a. passing gear down shift. Your mechanic might be able to help if you are having trouble looking behind the pedal yourself.

Mine doesn’t have it either. :(. 2004 ML 350 4 Matic SUV

Does it work on a 2019 A220 model

[@14ottallah]

Will this solve the issue where my car jerks when braking? Thanks!

[@johanverloop3128]

Yes it will, i reset my w204 C320 cdi today, and it worked fine afterwards.

Dave my 2003 e320 gear shift is sized ..i think because of a SBC or brake switch..but looking for the reset button in the center console space ..I can't seem to find the hole to push a pen to reset and unlock..where is the access hole..thanks ..John

I find it so funny when people who think they know things about Mercedes give out false information. not this guys fault, he was given false information by someone who thought they knew something. I have never heard of this reset function. not saying it doesn't do something, but there are several incorrect terms used here. 1) the switch under the pedal is the wide open throttle switch, yes it will cause a down shift but that is only cause the engine module told the transmission to downshift. 2) the key position numbering he used is incorrect. off is key position zero, next is key position 1, turns on circuit 15R, next is key position 2 which turns on circuit 15, next is key position 3 which activates circuit 50 for the starter. also, once the key is turned off, the engine and transmission module are not communicating. once the key is in position zero, that turns off circuit 87 which is what powers the transmission, be it the 722.6 or the 722.9. once power is removed, there is no communication taking place. also, a "smooth" transmission is a transmission that will wear out faster. harsh hard shifts do not wear out an automatic transmission. a smooth shift actually wears the clutches faster cause of the slippage that has to take place. an automatic transmission is controlled slippage and the more of that taking place the less life your automatic transmission will have.

He’s actually close....key to on pos. Hold acc to the floor for 15 sec, turn key off , keep holding pedal down for 5 sec, release pedal and don’t touch anything for 5mins then remove key and it starts relearn cycle

Well, thank you, professor!

[@ripcjw1999]

So how do I reset my transmission...

[@darrylgriff1123]

Good Morning! Just wondering which company you called for the Valve Body service here in SoCal? Thanks!

[@A_Renaissance_Man]

I am no longer 100% sure of who I called and talked to but, I think, and again I am not 100% sure I called European Autowerks in Temecula, CA. Also note that was 8 years ago so there might be a complete change in personnel from then until now. Good Luck and I hope they can help you. Transmissions are a Beast and Mercedes is the King of Complication.

I have a 99 Mercedes S class, a 320 petrol engine. but have some problems with the automatic gearbox if I start the car and switch it to its D or R, it does it very neatly and also drives smoothly without any problem. but sometimes when I park somewhere and come back and want to put it in D it thumps and won't shift into D. then I also only see the "P" on the screen and it just won't go. then i have to drive him in his 1. then I turn it off, then on again, then off again, then on again. and then I can just switch back to his D or R. What could be the cause?

[@A_Renaissance_Man]

Sometimes the electrical connector to the transmission becomes corroded when water gets into the connector. This is easy to access and look at. If the connector and the pins look clean then there might be an internal issue if no one has ever messed with the shifter.

excellent, thank you
