Solution
1. Preparation
  • Gather tools and materials: OBD-II scanner, socket set, transmission fluid, funnel, and clean cloths.
  • Ensure the vehicle is on a level surface and secure with wheel chocks.
2. Check and Top Off Transmission Fluid
  • Locate the transmission fluid dipstick or fill port.
  • Remove the dipstick or cap; wipe it clean with a cloth.
  • Insert it back and remove again to check the fluid level.
  • If low, add the appropriate type of transmission fluid as specified in the owner's manual.
3. Inspect Transmission Control Module (TCM)
  • Disconnect the vehicle battery to ensure safety.
  • Remove the TCM according to manufacturer instructions (typically requires removing a cover or panel).
  • Inspect for corrosion or physical damage; clean contacts if necessary.
  • Reinstall the TCM and reconnect the battery.
4. Test and Replace Brake Switch (if necessary)
  • Locate the brake switch, usually near the brake pedal.
  • Use a multimeter to check for continuity when the brake pedal is pressed.
  • If faulty, remove the old switch and install a new one, ensuring proper alignment.
5. Recheck Gear Shift Linkage
  • Inspect the gear shift lever and linkage for any binding or misalignment.
  • Adjust or lubricate as necessary to ensure smooth operation.
  • Test the shifting process to confirm proper engagement.
