Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the battery to ensure safety during electrical work.
Raise the vehicle using jack stands if inspecting undercarriage components.

2. Check Transmission Fluid

Remove the transmission dipstick and clean it.
Reinsert the dipstick and pull it out again to check fluid level.
If fluid is low, add the correct type of transmission fluid (consult the owner's manual for specifications).

3. Inspect Transmission Linkage

Locate the transmission linkage at the base of the steering column or near the transmission.
Visually inspect for any signs of wear or disconnection.
If damaged, replace the linkage with an OEM part, following manufacturer's specifications.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Disconnect the switch connector and test for continuity using a multimeter while pressing the brake pedal.
If defective, replace the brake switch.

5. Inspect Transmission Control Module (TCM)

Locate the TCM, typically found near the transmission.
Disconnect the wiring harness and visually check for corrosion or damage.
Reconnect or replace the TCM if necessary and ensure all connections are secure.
