Hey everyone, recently picked up a 2014 e63 and love the car so far! I have however noticed that no matter when the car is cold or hot, and no matter which mode I take off in, ( C,S,S+) the car seems to stutter then go, this only happens during take off? It’s a little better in C than the other modes maybe from the 2nd gear take off? I did recently do a diff fluid change with liquimoly oils about 100 miles ago and the trans was serviced within 5k. Also, I have done the sneaky trans reset that a few members recommended. I haven’t floored it from a dig but I do notice this issue about 90% of the time when taking off with about 10-15% throttle. Is this normal for these cars? My 2015 s class with the 7 speed doesn’t have these issues at all. When I took it to the dealer and my amg specialist Indy shop both said the car has no codes and runs fine etc… I’m a little bamboozled by this issue!
not sure if it matters but after the sneaky reset I’ve put about 28 miles and it seems more noticeable since doing this!
Thank you!

Isn't this common with MCT trannies ??
At idle the multi-clutch is released and needs time before its engaged.
I have been reading that too, I thought the w222 s550 shared the same transmission though, so I was a bit shocked to discover the “jumpiness ”
Same 7G 'transmission' but I'm pretty sure the S class uses a torque converter and the E and C class AMGs use the MCT mated to the engine. I also have a GL63 in addition to my E63 and the torque converter engagement is SO different than the MCT.
Is it any better w/ traction in sport (or off completely)? Sometimes the torque protection can get in the way depending on how you're trying to take off.
I leave extra room from a car in front of me when stopped. Then, release the brake and idle away from that stop for a few feet before touching the gas pedal. I remember reading someplace that its not good to let the car creep forward with the brake pedal slightly depressed. The starter clutch should be on or off and when the car is stopped, its stopped.

hmmm I haven’t tried playing with the traction control I’ll definitely give this a go!

so it seems as if this is a common thing with these cars? Nothing really to worry about?
Mct re adaptation with xentry or wet clutch plate replacement
sprintbooster
tcu tune
... lots in sticky on this, check it out
is it ok to drive like this though Peter? How would I know if the wet clutch plate is going out? Surely it would make noises or grind. Would it now throw a code of some sort either?
Are you saying this issue start after the trans oil change? Just a word, always try to use oem benz trans fluid and filter, in the future.
As stated, try having the MCT re-adapted via xentry, and or a full trans adaption, then drive for 500-1000miles and see if anything changes.

the trans was serviced before I bought it at the mb dealer, if I don’t have access to a xentry and won’t till I go back to the dealer (may be a while) is it safe to drive etc?

Driving an mct is like learning a bit to drive stick shift and modulate a clutch ... you can't just slam on the gas in a manual trans car you need to consider the clutch position - same here
lots of people coming from traditional torque converter trans vehicles don't like the mct or take time to get their foot to learn how to drive it
it may be totally normal - your situation or something needs adjustment .
no codes will pop up for a worn plate or a poorly adapted mct clutch plate.
it's safe to drive

sounds good and thanks! So it is apparently normal after reading through other posts. I definitely don’t mind it feels sporty if anything, next time it’s in for a trans service in November I’ll have them reset the adaptations etc. I usually service the trans every 15k miles… and yeah it definitely feels like learning to drive a manual!

sprintbooster helped my "foot" a lot with the mct .. small price to pay that may make a huge difference for you ... I have one in the 550i bmw and love it there also
but none of these ... sb.... tcu tune ... will help an already unhealthy clutch plate or poorly adapted mct clutch ... consider that first
your experience is really hard to describe in words, I could sit in your whip and drive it and be like oh yeah this is totally normal nothing to worry about ... or wow this ain't right ... too many descriptors for a unique issue

thats kind of what I’m worried about lol, the master tech at my local Mercedes and my Indy AMG specialist said it’s fine etc so maybe I’m just not used to MCT yet, but if there is a issue I’d love to get it fixed. Other than this it’s great it doesn’t build revs before moving like other people noticed
I don't have those issues with my tranny. Also a 2014 E63 4matic.
It's as smooth as can be. I always drive in S.
Stop and go, or fast starts, no yerkiness whatsoever. Got 65k miles and on 3rd oil in box.
Unplugged for 6k miles.
Only time the clutch is kind of harsh is during initial freezing temperature start and go.
After not driving the car for about 6 days I finally found some time to “practice” today ! I played with the modes a bit, and learned that driving in C and giving it just the right amount of throttle it takes off normally and smooth. I will say in S or s+, it is a little harsher but I’m sure i just need to learn those as well!
That's the best part about the sprint booster, when you wanna just feather the throttle, the sprint booster actually accelerates the pedal input to the TCU and overcomes this delay very quickly and your foot learns to appreciate a more familiar throttle experience such as one you have with a torque converter.
