Shifting from Parking

[architect]

I have a 95 Regal GS that isnt shifting from parking. The button won't depress despite holding it down and pushing in the brakes. 

Even before it would take a few seconds before the shifter button would depress but it was consistent. 

The car prevsiously sat for a few years on a slopped garage. I had issues with shifting it then as well but after giving it a go for awhile I was finally able to, even with a dead battery at the time. I haven't driven for a month with car parked on slope again so not sure if there is a common reason here. 

Mechanic has replaced transmission oil when I pulled the car from the 3 years of  sitting. 

Thanks.

I can't remember but do 1st gen cars have the shift lock release like 2nd gen cars do? If so you could try that. If not that solenoid might actually be bad. If I recall something about the brake light switch can cause the car to remain in park. I had that issues on my CSC. 

If the car was parked on an incline I would try rocking the car back and forth a bit then try to get it out of park.

I do have issues with the parking lights where only the centre window one comes on.  But never stopped me from getting out of park by waiting a few seconds. The job to fix the wheel switch seems like a bigger job? 

I'll try to rock or look to see if theres shift release.

No shift release and rocking doesn't help.
