Other than the e circuit errors thats normally fixed with a new solenoid they do seem to be incredibly stout
To be fair, those solenoids are not difficult to change. Had them and the entire mechatronic unit out and the seals all swapped in about half an hour (on the bench, add another hour if you’re doing it in the vehicle). Once the pan is off it’s like 5 bolts.
This was on a ZF6HP26x, but they’re pretty similar.
