Clunky/Slow Transmission? Try getting it adapted!
Hey guys,
I know we casually discussed this in another thread, but I wanted to get an official one with the right title for future people to search
Symptoms:
I think I'll break the issue into 1) Transmission shifts slowly when both using the paddles and in auto mode. I was just kind of unimpressed unless I was going WOT. 2) Clunkiness during downshifts and upshifts. i.e- nowhere near as smooth as either an automatic OR a DCT.
Solution:
I went into MB of Bellevue and told them I was kind of unimpressed wth the MCT in general. It was clunky and not fast...what gives? Kind of thing. I wouldn't go "DO AN ADAPTION YO!" because that's like going to a surgeon and telling them exactly what needs to be removed based on your google skillz.
Net net, they looked at it and decided that an adaption was in order. (I still don't actually know what this means, but I got the car back in under 24 hours so it couldn't be too hardcore)
Result:
They told me to drive around like I normally would and it should learn how I drive. I have to say, the difference is nothing short of remarkable. It was odd because it removed all the jerkiness of starting from a stop and in sport and sport+ mode the shifts go off near instantaneously. It felt as smooth and as fast the CLA loaner with a DCT that they gave me.
I have to admit, when shifting it manually, there is still sometimes a bit of jerkiness and sometimes it's not quite as fast as I would have wanted, but for 80% of my driving this was a massive improvement and quite noticeable.
Total Couch Mechanic Theorizing:
I think that the car relearns your natural shift points. Like under normal driving I probably like to shift around 2.2-2.8k rpm. My guess is that it figured that out based on how I accelerated and then it tells the next gear to queue up around there vs wherever the previous owner liked to shift, so that it can be ready for that RPM, faster? I have no idea, but basic automatic cruising is really where I saw the biggest, fastest improvement. It never felt slow at WOT, so don't expect that to get any better (though you're really splitting hairs if that was too slow).
Net net: You have literally nothing to lose by trying to get your SA to do this and it's covered under warranty if your dealer is cool i.e- MB of Bellevue.
Let's get more feedback in here!

I am glad it worked for you too.
It is important to keep in mind that your MCT (2014-15) hardware is slightly different than mid and late 2016 production year and that the software is not compatible-interchangeable between 2014-15 and 2016.
I still believe that the 2016 MTC is at least as good as the DTC I had in my late production 2016 GTs, but what do I know right
Nothing short of amazing improvement after the adaptation in my 2015 and 2016 wagons.
BTW what gears did Andrew adapted. I got 1-2-3-4-5-6-7 in the 2016, 1-2-3-4 in the 2015

Note for everyone: We both had this done at MB of Bellevue so your results may vary?
EDIT: I checked the paperwork and there is nothing about which gears are adapted. It just says "26940 Wet Clutch Adapt 1.20 - searched tips and found LI27.60-P-062141 related to issue.
No idea what that means, but seriously night and day difference.

Just had my wet clutch adapted this past week. Pretty incredible difference. I have a 2012 and it was perfect till MB did this retarded software update and jacked it all up. Lots of jerky takeoffs, S+ shifts were quite jerky under wot and the lag...... Really made me want to get rid of the car
It is all just about fixed now, cost me $395 though but definitely worth it.

I would be interested in how to perform this reset at home
I would also like it we could perform a full reset of everything. ECU TCU and let the car learn the new owner.
211s had some sort of trans reset 212 has that function...

The adaptation has nothing to do with "learning" how you drive. Adaptation is an actual physical (albeit via software) wet clutch and gear gap adjustment.
Just like adjusting the rear derailleur in a 10-11 speed bicycle. If you are really interested look like it is done in Shimano Di2, it is a very, very similar process.
As you drive, the car learns; or if you are in a hurry there is a properly documented and public reset.

I brought up and documented the process in a previous thread.
AJS started a new and clear thread so people can search.
Go to the dealer reproduce the issue, the dealer will do
a) a wet clutch adaptation (this addresses jerkiness and speed)
b) a gear adaptation (this addresses gear alignment and clunkiness)
C) a combination of A and B if your car needs it.

I believe it was done via SDS, but yes it was a combination of the wet clutch adaptation with some gear adjustments as well
I will say, I'm not so sure about how I feel about the new S+ wot shifts, feels a bit soft to me now lol

in S and S+ do you still have the jerkiness with jumping on the accelerator when you come to rolling stops at lower speeds?

mine shifts crappy in sport+ at WOT like a big pause. it feels better in sport. It feels like a newbie driving a manual from start stop. going to look in the WIS to see if anything is addressed. Im also thinking the a BOV would help the WOT shifts
#16
That's exactly how mine shifted on S+. Made for some aggressive feeling shifts but that pause was annoying. All gone work the adaptation
#17
The jerkiness in S and S+ is mostly gone. Very livable now. Feels more like the automatic 9 speed as you come to a stop in Sport plus mode

Shift times, especially if it's more responsive in M could surely make the car faster.
LMAO that you think this can't happen.

None of the people that have benefited from the adaptation has done a measurement. Not that would mean anything as the margin gained by the adaptation can very easily be mute by a human reaction time.
Maybe we should learn how to take a joke

I am sorry, I know it can happen after all it was ME that spent a lot of time, money and worked with AMG, my dealer to get this happening.

Well maybe somebody else who did the adaptation can relay if they noticed a difference in shifting speed...

What a great way of looking at it....to bad the transmission in the car is the Ultegra version it would have been so much better Dura-ace.

Despite all the nay sayers, it changed my cars. I believe I am pretty objective and that is why MB-AMG and my dealer (both in the US and Germany) worked with me. I was ready to dump all my AMGs they could not fix the GTs may glitches, wind noise and excessive oil consumption and sold it as a cheap rag. these wagons are something I will be hard pressed to sell and I do not get too attached to cars. As soon as they do not bring pleasure due to anything I move on.
Try it, you have nothing to lose but a few days in a cheap loaner
PS: as a cyclist I will say that the Ultegra-Dura-ace rear derailleur argument it all depends. Have you ever used a Dura-Ace rear derailleur in cobble road?
