Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and check the fluid level; add fluid if necessary.
Inspect the fluid's color and smell. If dark or burnt, a transmission fluid change may be required.

3. Inspect Transmission Linkage

Locate the transmission linkage at the base of the gear shift.
Inspect for any loose or damaged components.
Adjust the linkage as necessary to ensure proper alignment.

4. Test Range Sensor

Disconnect the electrical connector from the transmission range sensor.
Use a multimeter to test for continuity and proper voltage.
Replace the sensor if it does not display correct readings.

5. Reconnect and Test

Reconnect any components disconnected during the inspection.
Start the vehicle and test the shifting function again.
