Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, screwdriver set, transmission fluid.
Ensure the vehicle is in a safe, level area and engage the parking brake.

2. Fluid Inspection

Sub-step 1: Remove the transmission dipstick (if applicable) and wipe it clean.
Sub-step 2: Reinsert the dipstick and remove it again to check the fluid level. Add the recommended transmission fluid if low.
Sub-step 3: Inspect the fluid color and smell. If it's brown or has a burnt smell, a transmission fluid change may be necessary.

3. Transmission Linkage Inspection

Sub-step 1: Locate the transmission linkage near the shifter and the transmission itself.
Sub-step 2: Check for any loose bolts or damaged bushings and tighten or replace as needed.

4. Brake Switch Replacement (if defective)

Sub-step 1: Disconnect the battery to ensure safety.
Sub-step 2: Locate the brake switch assembly, usually near the brake pedal.
Sub-step 3: Remove the old switch by unscrewing it and disconnecting the wiring harness.
Sub-step 4: Install the new brake switch and reconnect the wiring harness.

5. Electrical Check

Sub-step 1: Inspect the fuses related to the transmission control module. Replace any blown fuses with the correct amperage.
Sub-step 2: Use a multimeter to check for proper voltage at the transmission control module connector.
