Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Disconnect the negative terminal of the battery.
2. Check Fluid Level and Condition
  • Locate the transmission dipstick (if applicable) or access the transmission fluid fill plug.
  • Remove the dipstick or fill plug and check the fluid level.
    • If low, top off with the appropriate transmission fluid (refer to owner's manual for specifications).
  • Inspect fluid for burnt smell or dark color; if found, consider a fluid change.
3. Inspect Transmission Linkage
  • Lift the vehicle using a jack and secure it with jack stands.
  • Locate the transmission linkage and visually inspect for any damage or disconnection.
  • If damaged, replace the linkage or reconnect as needed.
4. Test Brake Switch
  • Locate the brake light switch and check its operation.
  • If the switch is faulty, disconnect it and replace it with a new one.
  • Reconnect the battery and test if the vehicle shifts into gear.
5. Examine Transmission Control Module (TCM)
  • If applicable, access the TCM by removing the necessary panels.
  • Inspect for loose connections or corrosion.
  • If the TCM is faulty, replace it following the manufacturer's instructions.
