Default DCCD binding issues, not electrical

I'm running a V8 JDM 6MT with DCCD ran by a DCCDpro in my GD rallycross car. The transmission is used quite hard and has been through a few broken axles.


That being said, there is something wrong with my DCCD. Even with the controller disconected from the transmission, the diff stays locked. With the car fully in the air and the hand brake on, clutching out in 1st kills the engine. DCCD solenoid reads 1.9ohm on the multimeter.


I think the issue might be one of 2 possibilities:


-Clutch plates have warped/stuck togeter due to abuse.
-A planetary pin is backing out and putting pressure on the clutch pack.


Apparently the pins backing out is a 'common' problem with these but not much info out there about it. I found this:

Anyone else has had a binding DCCD issue that was mechanical? What was it?

What do people do to prevent those pins from coming out?
