I have been using Auto Tap to look around in the computer.
I had a transmission code listed but no check engine light.
The light does not come on when I turn the key.
 
The trans was rebuilt. What exactly is a PCS?

PCS = Pressure Control Solenoid
 
As the previous poster mentioned, it's a transmission component that commonly fails on this series of vans. While the part isn't too expensive, the labor is what kills you; I spent about $600 a few months back to have mine done.
 
Regarding your check engine light, not every code thrown by the computer will trigger a check engine light. Some conditions need to be repeated or exist for a period of time before a the CEL comes on. Have you verified that the CEL works; does it come on briefly as it should when you start the engine?
 
Good luck.
