Hi Captnjoe, I had a '94 PA with levelers that I fought for awhile. I found a combination of things that may help, assuming no major component problems.
The gear select column was very sensitive and had to be in just the right spot (in park).
There was an in-line fuse near the solenoids that had an intermittent connection.
And... I can't remember the third thing. May have been the switch on the emergency brake (adjustment) but I can't recall the details.
