- Locate the transmission dipstick (if applicable) and remove it.
- Wipe the dipstick clean and reinsert it to check the fluid level.
- If low, add the appropriate transmission fluid (refer to the owner's manual for specifications).
- If fluid is burnt or contaminated, drain the transmission fluid using a fluid pump or drain plug.
- Replace with new fluid, ensuring the correct type and amount is used.

3. Inspect and Adjust Gear Selector Linkage

Sub-steps:
- Remove the center console cover to access the gear selector.
- Visually inspect the linkage for any disconnections or damage.
- If misaligned, adjust the linkage according to the manufacturer's specifications.
- Reassemble the center console.

4. Replace Brake Switch (if defective)

Sub-steps:
- Locate the brake switch, typically found near the brake pedal.
- Disconnect the electrical connector from the switch.
- Remove the switch using a socket set.
- Install the new brake switch and reconnect the electrical connector.

5. Check Transmission Control Module (TCM)

Sub-steps:
- Locate the TCM, usually found near the transmission or under the dashboard.
- Inspect the wiring harness for any signs of damage or corrosion.
- Use a multimeter to check for proper voltage and ground signals to the TCM.
- If faulty, replace the TCM as per the manufacturer’s guidelines.
