Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check Transmission Fluid

Remove the transmission fluid dipstick or access point.
Inspect fluid level; if low, add the manufacturer-recommended transmission fluid.
Check fluid condition; if burnt or contaminated, perform a fluid change.

3. Inspect Gear Linkage and Cables

Lift the vehicle and secure with jack stands.
Visually inspect the gear linkage for any damage or disconnections.
Adjust the linkage if misaligned, ensuring it is properly connected.

4. Examine Transmission Control Module (TCM)

Locate the TCM, typically found near the transmission or under the dashboard.
Inspect for any loose connections or corrosion on the wiring harness.
If issues are found, clean connections or replace the module as necessary.

5. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If faulty, replace the brake switch.
