Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts if necessary.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and pull it out.
Wipe it clean and reinsert to check the fluid level.
If fluid is low, add the manufacturer-recommended transmission fluid.
If fluid is dirty or burnt, proceed to drain the transmission fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow fluid to drain completely.
Replace the transmission filter if applicable:
- Remove the old filter and install the new one, ensuring a proper seal.
Reattach the transmission pan with new gasket and torque bolts to manufacturer specifications.

3. Inspect and Repair Transmission Components

If issues persist, inspect the transmission range sensor:
- Disconnect the sensor and test it with a multimeter according to the service manual specifications.
- Replace the sensor if faulty.
Check the shift linkage and cables:
- Adjust or replace any worn or damaged components.
If necessary, consult a professional for internal transmission inspection or rebuild.
