- Parking brake is engaged: Make sure the parking brake is fully disengaged before attempting to shift gears.
- Shift lock solenoid: The shift lock solenoid is an electrical component that prevents the gearshift from being moved out of park unless the brake pedal is depressed. If the solenoid is faulty, it may not be able to disengage the gear shifter, causing the vehicle to remain stuck in park.
- Gear shift linkage: The gear shift linkage is the mechanical connection between the gearshift and the transmission. If the linkage is damaged or misaligned, it may prevent the gearshift from being moved out of park.
- Transmission problem: A problem with the transmission itself could also cause the vehicle to remain stuck in park. This could include a malfunctioning transmission control module or a damaged gear selector.
If you are unable to identify and resolve the problem yourself, it is best to have your Toyota inspected by a qualified technician.
