Do you mean the shifter is locked in the park position or does it move but the transmission stays in park? I need to determine if it is a park interlock issue or a cable issue.
Here are directions for adjustment of the cable. However, I need confirm exactly what is happening. Also, I will need to know if this has a column or floor shift design.

Shift Control Cable Adjust
Vehicle Transmission and Drivetrain Automatic Transmission/Transaxle Service and Repair Procedures 440-T4, (4T60/4T60-E) Automatic Transaxle Shift Control Cable Adjust
SHIFT CONTROL CABLE ADJUST
1. Lift up cable lock button, located near transaxle cable bracket.
2. Place transaxle manual control lever in Neutral position. Neutral position can be obtained by rotating the manual lever counterclockwise to Park position, then rotate lever clockwise from Park through Reverse to Neutral.
3. Place transaxle selector lever in Neutral position.
4. Push down on cable lock button.
Let me know if that helps or if it is something different.
