Not sure what pressure control solenoid is, could it be the fuel pressure regulator?
may be on top of the starter and replaced with same. Follow the + battery cable it will connect to the solenoid
The 1995 Cavalier could have a stopped up transmission filter, or a vacuum solenoid problem. These would be the two most likely places to cause the problem.
There could be different reasons the security light is coming on in your Chevy Trailblazer. The fuse could have blown or there could be a wiring short.

Had a similar problem. Mine was a shifter solenoid? ( i think) This was after I had the tranny rebuilt and it was still shifting very hard. Once they put the solenoid in no other problems.
the dashboard cluster could have broken. That happened to my 2004 trailblazer and I had to get it replaced
I could be wrong but what it sounds like to me is what is called the servo covers located just above the trans pan on the right hand side
