Does this still have a metal blade key not the "smart key". The smart key system uses a solenoid in the shifter base if I recall correctly.

99 should still have a cable that runs from the ignition switch to brake pedal to left rear trans. ( It points rearward ) This cable operates the shifter lock when the key is removed and allows the shifter to be moved from park when the brake pedal is pressed.

If you remove the hush panel below the steering column , above the brake pedal, you should be able to pull the cable that unlocks the shifter. You only need to do this to get out of park, all other gears can be selected without pulling the cable,
