Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert it, and remove it again to check fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual using a funnel.

3. Inspect Transmission Linkage

Remove any covers or panels obstructing access to the transmission linkage.
Visually inspect the linkage for wear, damage, or misalignment.
Adjust or replace any damaged components as necessary.

4. Inspect and Test the Brake Switch

Locate the brake switch, typically near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
Replace the brake switch if it fails to show continuity.

5. Examine Transmission Control Module (TCM)

Remove the TCM from its mounting location.
Inspect the wiring harness for damage or corrosion.
If necessary, replace the TCM with a compatible unit and reprogram if needed.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift through the gears to verify proper operation.
