C63S AMG MCT/Transmission Problem
i got following problem:When i drive around 2000rpm and i drive constant and accelerate just a little bit, the rpm slips around 100-200rpm in every gear.
as soon as i accelerate faster the problem is gone.
I think the MCT (wet clutch) open and close for a moment.
Transmission is rebuild and MCT is new.
Is this a tune/software problem?

I had this same problem and changed the transmission oil which fixed it. 32k miles it was a dirty green color and not blue. These mct units seem sensitive to older fluid
How many miles on the rebuild?

First thing let's try a transmission reset. Let us know if it solves your issue

Won't be the case, boost is controlled by the wastegate so can be set to come in at any range.
I also have pure1000 equivalent and having the same issue.

those spool like 900s.
your boost comes on too low? Below 3.5k mine slips above 3.5 it’s fine
Maybe your boost ramps in to soon or in low rpm?
