Eaton clutch problems

SPN 788 FMI 7
SPN 560 FMI 11

I was switching trailers one day and the lower gears seemed to be grabbing really hard and when I put it in Neutral, the truck shut off and wouldn't turn on until I pulled the fuse for the trans. These are the codes I was getting.

I drove another 300 miles and it did it again when I put it in N but was able to turn back over. Everything seems to be working okay but the faults stay.

The only other issues I've had is a SPN 752 FMI 2 when it rains really hard. Then the truck won't shift anymore until it dries off and then it starts working again.

I took it to a shop and they said the clutch was broken and something about the spring...

I've been told there is still clutch left from another mechanic and I don't see how the clutch could be broken.

What do you guys suggest?
