Mercedes Actros MP4 - Error 27F3E7 After shifting into gear, the car still stands still.

Hello gentlemen.
I have a problem with the Actros. Namely, after replacing the clutch and slave cylinder, the car shifts into all gears in the manual mode without any problem, but it does not drive. After converting to the automatic transmission, it shifts into gear but does not drive either. The slave cylinder cannot be calibrated, the diaphragm leak test works perfectly, the actuator opens and closes as well, but it still gives the error 27F3E7, the gearbox was removed, the disc and pressure were checked again, everything was OK, Sachs new, the whole set, but after removing the gearbox, it turned out that the slave cylinder was sucked in despite the lack of air in it. the system, after allowing the air-loving screws, came out and works normally, so the entire control cassette was replaced along with the selectors and valves, it only changed a little that there is no error And still the same thing happens after putting the gear in gear, the car still stands still

Well, yes... Maybe you should read what you send before you press Enter?
This car is from February 2014 and already has Mercedes PowerShift 3
I found something about it, but you have to send me your email.

My friend, I also once had a problem with this manufacturer`s clutch. It`s true that the Renault Magnum has an automatic. I replaced the entire set with the slave cylinder, the calibration was done and there are no gears. The slave cylinder fault came on, "clutch actuator too slow", or something like that, the gearbox was removed twice, I even installed the old slave cylinder. It turned out that the disc had a defect in its workmanship and was thicker than the manufacturer`s recommendations, which is why the slave cylinder fault occurred. I then installed a product from another manufacturer and it was ok

In my case, the new disc is two millimeters thicker than the old one, the old one did 600,000 km and there were no errors on the worn disc. And the clutch was slipping all the time, when I pressed the gas pedal harder, only the revs increased, but somehow it was running, now nothing seems to be working.

Added after 10 [hours] 28 [minutes]:

The car is in good working order, the cause of the error was the clutch pressure that was coming together too much. Alignment The old pressure plate, the new disc, the new slave cylinder went in. The old potentiometer and the car drives as it should

Hello
the problem still occurs???
