Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Shift Mechanism

Sub-steps:
1. Remove the center console cover to access the gear shift mechanism.
2. Inspect the gear shifter for any obstructions or wear; replace if damaged.
3. Reassemble the console cover ensuring all clips are secured.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick/fill plug and check the fluid level.
3. If low, add manufacturer-recommended transmission fluid until the proper level is reached; if contaminated, drain and replace the fluid entirely.
4. Reinstall the dipstick/fill plug securely.

4. Test and Replace Range Sensor (if necessary)

Sub-steps:
1. Locate the transmission range sensor, typically found on the side of the transmission.
2. Disconnect the electrical connector and remove the mounting bolts of the sensor.
3. Install the new range sensor in reverse order of removal.
4. Reconnect the electrical connector and ensure a secure fit.
