Have a 96 Olds LSS. Can't get the console mounted shifter out of park.

According to the service manual, the shift interlock works as follows: Pressing the brake pedal de-energizes the solenoid. The restrictor arm moves clear of the shift lever arm, allowing the gear selector to operate normally. The solenoid is located below the console shifter. It appears there may be a mechanical or electrical issue preventing the restrictor arm from moving clear of the shift lever arm. I can't attach diagrams of this system but I would look into buying a set of service manuals to diagnose and repair issues on your LSS. I got a set for about $40 on ebay.
