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 KZfaq 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.

Thank you very much Mr. Prokity. This video was very well done and I will gladly view any other things you learn and pass on to fellow MB drivers. Have a great day and post soon!

Thank you so much. I noticed my car really running bad after getting some bad gasoline. I took it to my mechanic and he changed the plugs and coil packs. The car was still shifting rough. Did the relearn and now my car runs perfect. I was just getting on my computer to look for another car and saw your video.

Thank you very much for sharing. I did this on my W211 and it improved the drive drastically.

Brilliant (unknown by me) tweak that WORKS! Now, I do that monthly to my E320 and especially before days of highway driving and upon returning to local, stop-and-go driving. Thanks for sharing it.

Thanks very much David for your video. You have solved my 2005 W211 E200K upshift issues. I thought I need to change the transmission oil since its overdue at 60000 km and I did it at 100000km. But still getting a delay upshift. So after watching your magic video. I reset it . And it FIXED> you are the best ...

Not yet on deck for a W220 but, your vids on them are a good source of info. Kudos!

My heart almost dropped out of my body when my car wouldn't change gears! So grateful for KZfaq and videos like this. You know pulling into a MB dealer for repairs is automatic $200-$300. I'm saving this video.....

I have 2006 Mercedes S 500 low mileage and best of all it was given to me. Then the check engine came on and I'm thinking that nothing is for free. Followed video and it worked like a charm. Thank you for putting this out there.

omg ty! just bought a slk, and was shifting crazy, fixed. again ty.

Oh my goodness! Thank you so much! After having to drive home at 20mph, I thought I had torn up my husband's car! LOL. I performed this relearn/reset and it worked and he is none the wiser, lol.

This worked in getting my 2013 ML550 unstuck out of park where it would not shift into any other gear. Many thanks.

Thanks for the video, this worked on my 1998 CLK320, the transmission is shifting normally again.... i didn't even know the CLK320 had an "adaptive learning" transmission, but apparently it does. Saved me a trip to the mechanic.

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.

This really worked on my 2001 s500 thanks for the awesome video probably saved me alot of money 👍

David This video is excellent. I have a Smart forfour and after the battery drained one day and was jumped back into life, I couldn't get any drive in forward or reverse gears and had the following message on my car screen: Brake force distribution inoperative STOP The smart car is also an auto, so I tried your procedure and it wiped the message off and the car was able to start and go back into transmission. Thank you my man. D

It is still relevant in this present time even for the current model, even for E53 AMG. Kudos. Just did mine. Excellent. Brilliant.

Thanks a lot for the video. I have 99 c230( w202) and it’s not downshifting and upshifting much much better .

There we have it. Excellent, it is said that this need to be done after you change the fluid in the box. And that you need that star computer hooked up, i suspected there was another way!

Mine doesn't shift hard.. However good info far as once a month routine .. I didn't know that ... Ty

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. :)

Thank you. It works much better now. I have a E320 w210 and never did this proceduce in 8 years. All maintenance and oil, filter changes but never the reset or relearn procedure was done. I used the W S switch but not this relearn procedure, and now I feel like having a new car much better and smooth response. Thanks a lot!!!

Thanks for the tutorial, I did it to my W211 and it was like driving a different car afterwards - BRILLIANT!

Thanks mate. This really helpful. I found one vid exactly like yours but he said press down the BRAKE for 15sec. and 200% that's insane

Wahooo!!! We’re back baby! This procedure worked like a charm on my 09 E350. Key words (smooth buttery shifts) Thanks! For that a video and clear directions. Really appreciate it 🙏🏽

Thank you for sharing the info i will try this today . 👍

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

Thank you! Was so confused with the check engine light when there wasn't a limp mode situation going on

Thank you so much!!! My wife’s 2003 C230 Kompressor Coupé Rides so smooth!! Thank you!

Buttery smooth!, got it!

Really good advice for Cl 500- 2003...like new again, smooth changes up and down ...you saved me a lot of money and aggression... Thank you very much.... do u have any more tricks..?? Lol

Ypu have helped me immensely and saved me money.

Thanks very much for this video, it worked on my e55 amg..

Yes sure , good video. As a Benz owner it's important to know all these tips. Thanks

Works. Just bought a 2006 S350, mint shape but automatic upshifting was not smooth and was slow to shift up. Tried this simple reset and it worked great, first time. Upshifts now as it should correct timing and smooth.

Relearn mode! thanx man

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

thank you!! I just tried with a 2001 E320 and it worked very well. After replacing the battery, my car was running in 2 gear and sometime at stop lights it was not running at all. Now it runs smooth and shifts very well. I still have an engine light on, so I am looking for a solution about it. Thanks.

doing it to mine at the moment, 12:13 am CST, Chicago traffic is playing hell, sometimes I like to stomp it at the lights, but most of the miles out on the car is out on the interstates. which is where it absolutely rules...

I never feel mine shift at all... so smoooooth!!

I disconnected the battery on my 97 C280 only to find the sun roof sticking and not operating as it should,and the transmission was hanging on in first and second gear.After i did a reset on both everything works fine. Thank you for the info.

I have s320 w220 2005 and this worked for me too

I must say thank you - along with everyone else. And the post about the S500 being superior warms my heart. I'm driving one, a 2006 that has more than 300 thousand miles on it; essentially, it's maintenance free. Yes, I add oil and antifreeze when instructed to do so. I really love my Mercedes Benz S500 4Matic. Thanks again !

Thanks for your advice.And now I feel my 306hp.Thanks

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

very smart!! thanks buddy

worked for me today. Car wouldn’t start after battery was unplugged. This fixed it. Thanks.

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?

Thankyou very much David Prokity Sir! will try on my w221 S550, kind regards

I did it on a s550 2008 and worked good. Thanks!

Huge difference on my w215! Thanks

just what I needed

how long to wait after you did it first time?

tried it and reset my 98 c230 as described thank you

Does this also work on a W220 S500 Pre-Facelift?

You saved my live🤙🏼👌

excellent, thank you

Tryin now thank you 🙏

Thanks David!!!! It worked.

i think my gearbox is broken . but the shifts between the gears working feels amazing now . will do this again if i swap gearbox

Bro you are the bomb save me a lot of money in car feels smoother already S 500

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

Helpfull, thank u👌

Henry, Here is what I found. My starter battery was going out, this is the battery up front in, the engine compartment. Then I also load tested the battery in the back and it said it needs to be replaced due to the amperage being to low. Long story short, that tranny reset/ learn more works. My batteries being low and 1 bad caused this other issue. After replacing both, all worked fine.

Thank You so much for your help.

When?Why I must reset transmission .my vehicle can't run over 100 km on the low hill course. Even way no problem. Can I solve it by reseting?

So helpful! Thanks a lot 🙏

Does this work on a 1999 Vito w638? It won't shift up in 4th gear every time..

Super good

Great....Thanke you !

I just change the value body in February this year and now I am experiencing my 08, clk350 benz straining to move in gear. is anyone had or having this problem, I will appreciate your assistance? thanks,

Brilliant thanks

Thank you!!

This is good for my transmisión

I did this and it does work

I just did my first 900 miles toad trip with my 06 S430, I was having this exact issue. At times the shifting felt wrong, I had to stop and pull over. Turn the car off for 5 mins, then restart and it was fine again. I’m going to try to do exactly what you said and. See if that helps.

Also, that would be the "kick down switch" at the bottom of the gas pedal.

Thank you sir

I tried too and all jerking while shifting gear is gone! but still I feel some jerking may be thats because of motor mounts or gear mounts needs to replace... any ways thank you.

You think Turing it off for awhile and restarting will help

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?

How do I real e my Benz gear entering code and won't shift from the 2nd gear

Wao....That was awesome!!!!! \it works perfectly....Thank you so much for this!!!!!

Does this work for ML270?

4:19 that's my 'ish!...

Thank you

thank you.

Its the same för my chevy camaro 1988?

Thank you for this video worked for my transmission issue

Thanks. I did not know about that switch. I put a rubber floor mats in my car. I cut out a spot for the bottom of the peddle but let the rest of that area(switch) to be covered by the mat.

Thank you I will try this tonight

I prefer my trans to shift a little firmly, lasts longer, less slippage ... easier on it, plus, being in Chicago and doing most of my miles at high speed I crazy traffic, let's just say, she gets to stretch her legs. it's fast shifting, it's firm. your transmission will actually last longer with a firm shift is the moral of the story.

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?

Your video is clear and specific. Which year and model did you demonstrate this procedure on? I just bought my first MB and am going to try this after i get a couple of small items taken care of.

I have the best comment ever! AAMCO recommended I have them take the tranny apart and look at 3 and 4th gear for $800!!! I asked them if they didnt find anything then what? then change the TCM another $1000. Drop the pan and drain and refill with new filter $860. So I said I will take it home and think about it. When i floored it it would go to neutral after a heavy bucking sound. Performed the reset procedure and VOILA! It went full speed so i can pass in the oncoming lane and then shifted back up to OD like normal! if you ever come to Phoenix Drinks/Dinner on me Bro!

Buttery smooth Mercedes’ transmission yea that will be the day

Can this be done on a 95 w140?

My 2010 c300 4matic doesn,t have the button,on the accelerator pedal. I s there a way to do it w/o the switch ?

I have 1997 E320 and 2010 ML350 are those transmission "adaptive" I have the shift issue that you ar etalking about. Thank You.

Take that kick down button out and you will find it's not connected to anything, so I doubt that that provides the throttle position feedback. But I get the gist of what you are saying, pedal to the metal!
