Pinpoint Test Q: Stuck In Park

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    • Brake Shift Interlock (BSI) 

      • If the selector lever can be moved from the park position, but the transmission remains in park, continue with this pinpoint test.

    • Gear Shift Module (GSM) 

      • If any diagnostic trouble codes (DTCs) are present in the GSM, RESOLVE those first. REFER to the DTC Chart.

      • Using a diagnostic scan tool, access the GSM and monitor PID GEAR_CMD. Move the selector lever through all gear positions and make sure PID GEAR_CMD matches each selector lever position. If PID GEAR_CMD does not change with the position of the selector lever, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) - Vehicles With: Console Shift .

    • Powertrain Control Module (PCM) 

      • If any diagnostic trouble codes (DTCs) related to the transmission or GSM are present in the PCM, resolve those first. REFER to the Master DTC Chart.

    • Internal transmission components 

      • Carry out the line pressure test. If line pressure is low, refer to the Line Pressure Diagnosis Chart for further diagnosis.

      • Inspect the park pawl, park pawl actuator rod, TR sensor and park return spring for damage or binding. Make sure all park components are properly installed and connected. REPAIR or INSTALL new components as necessary. REFER to: Transmission .

      • Remove and inspect the park lock pawl valve. If the valve or bore is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body .

      • Disassemble the main control valve body and inspect the park lock pawl valve hydraulic circuits for damage, leaks or blockage. CLEAN or INSTALL new components as necessary. REFER to: Main Control Valve Body .

      • The shift-by-wire variant of the 10R transmission uses hydraulic pressure from the B and D clutches to push the system out of park. Check the B and D clutches for a does not apply condition. REFER to: B Clutch . REFER to: D Clutch .
