⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Ensure the vehicle is in a stable position to prevent rolling while working on it.

Symptoms

•Unable to shift the gear selector out of the 'Park' position
•Illuminated 'Shift Lock' indicator light on the dashboard
•Brake pedal feels stiff or unresponsive when attempting to shift
•Possible audible clicking sound when attempting to shift
•Engine starts but cannot move the vehicle out of the parked position

Diagnostic Steps

1
Check if the brake lights are functioning; if they do not illuminate when the brake pedal is pressed, it may indicate a faulty brake light switch.
2
Inspect the gear shift assembly for any visible obstructions or mechanical failure.
3
Test the shift lock solenoid for proper operation using a multimeter.
4
Verify that the vehicle battery is fully charged, as low voltage can affect electronic components.
5
Check the transmission fluid level and condition; low or dirty fluid may inhibit shifting.
