Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Transmission Fluid

Tools Required: Socket set, transmission fluid pump, fluid catch pan.
Sub-steps:
1. Remove the transmission fluid pan using the socket set.
2. Drain the old fluid into the catch pan and inspect for metal shavings or debris.
3. Replace the transmission filter if applicable.
4. Reinstall the pan with a new gasket and torque to manufacturer specifications.
5. Fill the transmission with new fluid, ensuring to use the correct type as specified in the owner's manual.

3. Adjust or Replace Transmission Linkage

Tools Required: Wrench set, torque wrench.
Sub-steps:
1. Inspect the transmission linkage for wear or damage.
2. If necessary, adjust the linkage as per the service manual's specifications.
3. If damaged, remove the old linkage and install a new one, ensuring proper alignment and securing all fasteners to the specified torque.

4. Test Transmission Range Sensor

Tools Required: Multimeter.
Sub-steps:
1. Locate the transmission range sensor; it's usually mounted on the transmission.
2. Disconnect the sensor and test its resistance and voltage according to the manufacturer's specifications using the multimeter.
3. If the readings are out of range, replace the sensor with a new part.
