Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, multimeter, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery negative terminal to prevent electrical short circuits.

2. Check and Replenish Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean and reinsert it to check the fluid level; add the appropriate transmission fluid if low.
Inspect the fluid condition for burning smell or debris, and replace if necessary.

3. Inspect Transmission Linkage

Remove the cover around the gear shifter if applicable.
Check the linkage for any signs of wear or damage.
If misaligned, adjust the linkage according to the manufacturer's specifications.

4. Test Brake Switch

Locate the brake switch on the brake pedal assembly.
Use a multimeter to check for continuity when the brake pedal is pressed.
Replace the brake switch if it is defective.

5. Examine Transmission Control Module (TCM)

Access the TCM, usually located near the transmission or under the dashboard.
Inspect the wiring harness for any loose connections or damage.
Replace the TCM if it is found to be faulty after testing.
