Well, 700 miles now, and the car is back in the dealership for the transmission malfunction.
While driving at 30mph, we lost 1,3,5 and R... drove it straight to the dealer, again. They saw the message this time. We never turned the car off. Told them we didn't feel safe in the car anymore, and they better find what's wrong with it.
The constant is that we lose 1,3,5,R and not the other clutch. Some lose 2,4,6. We'll see what they say this time.
