instructions to open PCM box
Does anyone know how to open the PCM medal box to get to the printed circuit?
I took all the screws out, so there must be a trick to it.

The PCM is what they call "none serviceable". Meaning, when one is suspected of being bad they remove it, chunk it and install a new one. So, there is no procedure in the service manual to open that puppy up. I'm guessing you'd have to break it (EEK! Moisture!) to get into it.
There are a host of diagnostic hints and tricks we could point you towards for solving your problem. However, if you're at the point of cracking the PCM I'm guessing you've exhausted all those other options!
Good Luck!

I would expect the boards inside the aluminum PCM case to be 100% encapsulated to prevent environmental conditions from effecting the boards or components. It's a common practice to protech this sort of electronics. That said, you can often bake the board at controlled temps/times to soften the RTV up so you can access portions of the board. But you had better have the drawings showing you where you need to go vs trying to access the entire board. (one of my past lives was at an aerospace electronics manufacturer and we would need to rework parts from time to time, not fun)
So even if you open it up, it's very unlikely you will be able to see the boards and components to check things out. Plus, you're going to make it so the dealer wont accept the PCM as a core (do they still do this???) when/if you need to replace it.
Things are non-servicable for a reason, it's not just so they can sell you an expensive new assembly.
