Im a Mercedes Tech (retired now) and this is the first time seeing this method of resetting shift adaptation values. Actually I like your video because it resets the shift values at both cold and hot. When you use the key method I think your wiping all shift values and the car will have to relearn or better said adapt to the drivers habits. The Mercedes Benz DAS software actually records the shift adaptation values in 3 different temp ranges cold medium and hot. Usually the shift adaptation values are transferred over to a new conductor plate by the technician when replacing the plate in order to avoid the hard shifts that occur when installing a new conductor plate on the 7G transmissions (722/9) But when this data is lost due to a total failure, like the TCU is beyond reading its data, then the shift element can be adapted individually in DAS. Once you perform for say the 1-2 shift adaptation or learning manually it will display a page with the shift adaptation values in the 3 temp ranges. Those 3 ranges are learned by driving the car. Always the best way to do any and all of these type of things is if you have the Mercedes Laptop but I understand not everyone can afford one as they are very expensive. Im just throwing all of this talk out there to help people better understand these cars. The Mercedes with the 5 speed trans (722/6) are basic and cheap to service and replace the conductor plate, but the 7 speed (722.9) cost a lot more and require SCN coding and adapting the part to the car. This is done on the laptop. Then you have to have a login and password to connect with Mercedes Benz too. So just having the laptop wont get you there you also need to know someone who can log you in or go to a shop that has the expensive Mercedes Benz subscription! So for the 7 speed yes you can do the filter services but a shop is recommended for the conductor plate. Now if you only have a speed sensor code yes you can replace it yourself if you have mechanic skills as they are available online on eBay. If you get the output sensor code address any ABS codes first as a wheel speed sensor can make this trans code pop up. The Engine Trans and ABS computers all work together and share data with each other through the data bus known as the CAN which is communication area network a 2 wire data bus where all the ecus talk to each other. Well the coffee I was drink just wore off and Im talking too much here. Thanks again for your video! Hope everyone take good care of their cars!

Pops just recently past away, and he was a Baby Boomer. Who was a Technician/Engineer/ Fiber Optics Installer, and always DIY'd everything. I just inherited a vehicle, 1999 E320 4 Matic. Over 200, 097 miles lol. I've came across your videos and Page and am so blessed by your wisdom and knowledge. It's actually encouraging me to restore the whole vehicle lol. Thank you for what you've done, what you're doing on this channel, and will like to support this page and start using your website. All the way from Kansas. Thank you again.

As always I like the videos you do, helps me and other Mercedes owners out tremendously. Looking forward to the transmission fluid change video for diy followers.... My GL is around 145, 000 miles now. Oh yeah, 1736👍

Eric, I can't even count how much time and money you have saved me on my E350 & GL450 over the course of your videos. Thank you once again. This worked no mire thump no more bang when putting it in reverse. Thank you, thank you 🙏

My friend at MERCEDES says the only transmission reset for pre 2010 vehicles is the engine key to position II, floor accelerator for 30secs, turn key back to off, release accelerator then wait two mins, never heard of this.

Just had the two speed sensors changed in transmission due to clunky changes and getting stuck in limp mode. Used to have to do the reset method every few days til it no longer worked and car was stuck in 2nd gear.

Sounds doable. I have an 06S 55 AMG. The only issue I have is downshifting from 2nd to 1st seems a little hard so I’m gonna try this and I’ll get back to you.

[JeffGalindoBHappy]

1736. Just bought a used 2007 ML 350 and I’m trying to learn as much as I can about it and your videos are great.

[starmartin]

A Huge Thank You. Bc Your Video Got My Car To Open. I Haven't Driven It In Over A Year. So Battery Was Dead. Again I Appreciate

[puresounds]

Hmm, guess it was my question answered. Many thanks, will try this out.

[timmitchell]

...."17:36", thanks for the info. as always. Considering buying a 2009 GL 450 today.

During a test drive the tranny felt like it was in low gear due to the sound and pull of the engine, not to mention the "reverse" gear limitations ....speed reduction.

[louisdeen]

very informative and much appreciated. I just bought an S320 and having that transmission problem. I will try this tomorrow.

1736 this guys knows his stuff thank you

[miltonbro]

Thanks for this video! I have been having rough shifts when coming to a stop or when shifting from Park to Drive. On my ML350 and have noticed this in my c230 though not as bad. Please post a video about changing transmission fluid & filter. Thanks!

[mygodisable]

Great video Keith, you give the best advice and tutorials . Also I left a message awhile back about getting rid of late oil change message & messages of that sort. Thanks.

[lorralorra]

1736, I have a merc ml 350 2007' learnt things from u I never knew, absolutely fantastic..lorra

[rebirth]

1736. On behalf of all Mercedes Benz owners, thank you Brother! I will perpetually introduce MB owners to your channel!

[freedombearreviews]

I have an ML 350 W164 - 2008 and I have this sound when going from D ro R. I'll try this when I get my car back from mercedes. I was getting a service engine light and they are doing the brake recall for free though.

[marinosal]

Thanks 1736- you’ve been a world of knowledge.
