Transmission initial slipping into drive when very cold
I have a 2018 c63S coupe. Now that winter is here and it has become cold overnight, I have noticed that when I start up in the morning and put it in drive (2nd gear start in comfort mode), it revs but it doesn't actually move forward for a moment until it kicks into gear the first time, and thereafter it drives just fine.
Is this normal for the 7 speed MCT in cold weather? Only happens when overnight temps get below 40 degrees and only on first start up and very first engagement into drive
Thanks

The oil is quite thick and it takes some time for it to fill all the passages of the valve body and the clutches.(remember there are clutch packs in the trans in addition to the multi plate pack replacing the torque converter)
After starting wait 30 sec to a min and then put in rev to back out of garage and wait 5-10 sec before moving and when ready to go forward wait another 5- 10 sec and that is the last time for the day needed to do it unless it sits out in very cold weather.

It's normal. If you're in comfort mode the car starts in 2nd gear. If you've ever driven a manual you'll know the feeling of starting the car off in second vice third gear.
Kick the car into any other drive mode other the comfort - problem solved. No need to stress, the car is all good.

What is the temp and how long do you wait till you shift into gear and how long so you wait till you try to move?? cold oil means you should give it a little longer . Remember this trans is diff than either a fluid coupling or a dual clutch.

Then agreed. That does not sound normal as my '18 coupe does not perform that way. Granted, I'm in Charleston, SC and it's 70 degrees in November.
Possible that it's a software issue and can be easily resolved. Keep us posted.

Then at least 5 seconds after putting the car in gear....

Mine does the same, it's OK after things warm up.
Also, sometimes the electronic parking brake kicks in automatically, but if you gas it hard enough, it will release automatically. This could also be what you are experiencing.

It's not a parking brake "delay" issue.
Yes, I do wait until the idle comes down before going into reverse out of the garage. Reverse doesn't seem to be an issue at all.
It's only on first engagement in drive on a COLD morning that it delays engagement and slips/revs for a few seconds, until it catches.
After that first initial "catch" into gear going forward, no issues.

Same here, taking off from a cold morning start the car dosent actually move until around 3,000 rpm. Almost like your riding the clutch in a manual car. I only drive on sport+ and allow the car to warm up for more than 5 minuts before driving, plus give time for the rpms to stabilize in gear before taking off.

Those of you who live in extreme cold conditions, Please allow 3-5 minutes warm up before you drive off for the sake of engine and tranny and don't listen to the 30 sec warm up bullsh*t.

I live in Los Angles, California. Doesn’t get too cold down here, around 50 degrees(F) the lowest on a very cold night. Plus I allow my car to warm up well over 5 minuts after a cold start. My tranny and engine temps are in the 80s before I take off. Still having the same issue, dosent seem to be a an ongoing problem though, because as soon as the temps reach closer to 100 I don’t feel the slippage of the transmission anymore.

That happened to me when I rented a C63 sedan not long ago (in cali). It felt exactly like somebody said: like 'riding' the clutch in the friction zone, but not releasing it completely. Got the car up to about 3K rpm, and nothing. Didn't feel good, so stopped. The DCT on my Porsche has never done any of that. Anyway, then decided to just gun the throttle with the left foot on the brake (if necessary), and it finally caught. And it wasn't cold at all; maybe high 60s, and only slightly uphill backing up. That tranny is my main concern about these cars. Still undecided; need to test an E43 (and E400 coupe with airmatic) to make the call.

C63s coupe
transmission sliping when cold
i have a 0ctober build 2016 c63s coupe and I have the same issues' Mercedes say its not normal and could not fix it so they involved Mercedes Germany and they same they seemed stumped. so the first defensive question to the dealer was check the car for any modifications so they could walk away.
there was none so over the course of 3 to 4 weeks they tried software fixes that did not work then came the resetting of the adaption points on the cluthpack that didn't solve it then came readaption points on the ENGINE after injector values were taken and sent to Germany. I got the car back improved but not fixed then a month later took it back and further readings and values sent to Germany and the response was to change injector no.2 on the engine as the values were to high. very confused on how it is all connected I am still waiting for a fix as I still have the problem. I have asked them to have a definite fix before I give them the car again.. anf further to that my stop start dosent work either not that its a problem as I never use it.

This is normal, I have a 2018 and it does it in drive and reverse (sport mode). Once I drive it, about 3 - 5 mins it then starts in 1 all depending on how cold is outside. Letting it idle yields no effect as I've had it remote started for 5 mins vs driving for 5 mins to test it out, and driving is what warms it up.

Can anyone who's had this issue and a dealer look at it, send me their VIN in a PM?
If not, I can provide dealers email.
This isn't normal and Mercedes claim I've destroyed the wet clutch and want $8500 to repair.
It's been going on since day one, 8 miles and I now have 9k.
Any help appreciated.
The situation gets worse with miles and had now become dangerous with the car chattering to stops.....

It's not just in the cold either because it was 88 here today and it did it. It does get better after a couple more stop starts. So I guess I'll call my dealer and have them document it just in case something happens down the road.
