Are you familiar how it works?
As soon as you manually interact with paddle shifters, the tranny stops shifting automatically to becomes manual. 100% NORMAL.
Watch couple video or better read owners' manual.
There are couple ways out of manual mode, my favorite is to hold the up shift paddle. You can switch tranny mode by toggling S/M switch.

That's interesting... your tranny only shifts manually.

truly stuck in manual...
This is a serious hard fault of the TCU.
Somebody is going to need to scan your tranny to retrieve a list of fault codes.

You are saying your tranny simply never shifts gears up automatically not even 2nd or 3rd. It only shifts down. Failures to initially shift up is not caused by paddle interactions.
This is a serious hard fault of the TCU.

of course not replace the TCU without knowing why it quit shifting!
Now we can guess it's in limp mode.
The best course is to troubleshoot what your problem is. Tranny is extremely dependent on network partners.
Scan the whole chassis to get more data.

Make it a habit to not only to tell of DTC numbers, always provide the description and the brand of scanner being used.
This will speed up assistance by members.
Some scanners may use generic DTC, an MB compatible scanner will use MB DTC, which often the description usually is more accurate. Well they made the car

Good, Launch for MB is very very good.
ADD : Update your scanner software, that MB software V49.68 is a few generations ago.

Hang on my man.
Do the simplest one first.
This TCM is powered by Relay R, a mini relay.
There is a TSB on this relay R type, you verify your relay first. There are 3 or 4 of similar mini relay like relay R in my car, in ur car probably the same qty.
I am afraid intermittent low voltage may be an issue , for the TCM from Relay R.
Go and read here the TSB. https://www.tsbsearch.com/Mercedes-B...54-15-P-057373
I do not know why I cant load it here
as a PDF. OOps it actually stick-ded hahahah

Weak battery can give you problems you can't even imagine.
Also please check the undocumented ground cable under the car I call W-TF is tight and clean and make sure W10 battery ground to suspension strut is clean and tight.
Read here : https://mbworld.org/forums/e-class-w...ital-wire.html
If your location has winter, the diesel glowplug sucks lots of battery power + road salt causing corrosion on the W-TF undocumented ground cable.
Also your alternator wiring is probably is still the YoYo kind low voltage happy, ECO friendly bull-shi-et where your battery is never 100% charged. ECM does not allow it, in the name of greenie.
