Welcome to the forum.
If it was me, I would take it to a transmission shop and have them check it out. Could be just a matter of linkage adjustment or a major transmission overhaul. Good luck.

It's the Auto-Park brake, a drum-type brake that gets applied to the drive shaft when the transmission is placed in Park. The brake "shoe" is just behind the transmission. Either the wiring to it or the brake itself isn't working. On a 21 year old coach, it's likley the mechanism itself is failed. If you Search here or on the internet in general for Auto Park brake you should find many references. Probably some videos on YouTube as well.

It's not part of the transmission per se, though it is triggered by putting the shift lever in Park.

I went thru the same problem a few years ago a RV on a Workhorse chassis.
Here are a couple of links that will help you to understand what is happening, and one is a solution.
I'm posting as information, not suggesting.

Everyone is jumping to the conclusion that this is an Automatic Parking Brake issue, and it might be, but not all Chevy P30's had automatic parking brakes, it depends on the GVWR, the lighter sub 15,000 pound (usually 154 inch wheel base) models had a conventional parking pawl in the transmission.
