Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and pull it out to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the correct level.
Inspect the fluid color and smell; if burnt or dark, a fluid change is required.

3. Inspect and Clean Linkage

Locate the shift linkage under the vehicle.
Inspect for any damage or disconnections; if damaged, replace the linkage.
Clean any debris or dirt from the linkage connection points.

4. Replace Transmission Fluid and Filter

Drain the old transmission fluid into a pan.
Remove the transmission pan bolts and gently lower the pan.
Replace the transmission filter.
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically around 10-12 ft-lbs).
Fill with new transmission fluid according to manufacturer specifications.

5. Test Shift Range Sensor

Locate the transmission range sensor.
Disconnect the electrical connector and use a multimeter to test for continuity.
Replace the sensor if it fails the continuity test.

6. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and attempt to shift through the gears to ensure proper operation.
