There should be a slot in the shfiting console to insert a small screwdriver to unlock the shift lock.
The shift interlock release is on the side of the console. Take the plug out and insert a key into the opening. Then, shift out of park and start the car.
Sounds like your shift interlock mechanism is jammed. Assuming yours has a floor-mounted shifter, there's usually an override button on those, which requires you to pull up the rubber boot around the shift column.
it controls the overdrive function and shift timing relative to speed
the shifter lock need to be lubed to override the shift lock press hard on the brake and move shift over to unlock and pull down this will override it but not fix it remove shift covers and lube shift lock and should be fine
It is the acuator located in the console where the shifter is at. The only place I could find this part is the Ford Dealership.
You would need to specify which transmission you have. On the older autoshifts with the clutch pedal, you could override the automatic function to get it to downshift manually, but you couldn't override it on the upshift. Some of the modern clutch free automatics have a feature which allows you to do this.
The shift solenoid is under the console in the shift assembly.
I'm not sure about a Pontiac, but on my mom's Ford Escort it is located under the all the plastic housing where the gear shift is mounted on the floor. It should be located somewhere near your safety interlock override button, as this is attached to the solenoid itself. You can use the override button to bypass the solenoid if it quits working so that you can get at least get your car in gear until you get a chance to replace solenoid.
