Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, screwdriver set, transmission fluid, funnel, and multimeter.
Ensure the vehicle is on a level surface and the engine is off before starting any work.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if applicable).
Remove the dipstick and wipe it clean, then reinsert it to check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
If fluid is dark or smells burnt, drain the transmission fluid and replace it.
To drain, remove the transmission pan bolts, allowing the old fluid to drain into a pan, then replace the filter as needed.

3. Inspect and Repair Transmission Linkage

Visually inspect the transmission linkage for any disconnections or damage.
Tighten any loose connections and replace any damaged components.
Adjust the linkage if necessary to ensure proper alignment with the transmission.

4. Replace Brake Switch

Locate the brake switch, typically near the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch using a socket or wrench.
Install the new brake switch, ensuring it is securely attached.
Reconnect the wiring harness and test the switch operation.

5. Reset Transmission Control Module (if necessary)

Disconnect the battery for at least 10 minutes to reset the transmission control module.
Reconnect the battery and start the vehicle.
Test the shifting to see if it resolves the issue.
