Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Disconnect the battery to prevent electrical shorts.
2. Check and Refill Transmission Fluid
  • Locate the transmission dipstick or fill plug.
  • Remove the dipstick or fill plug using a socket set.
  • Check the fluid level; if low, add the appropriate transmission fluid (refer to the owner's manual for specifications).
  • If the fluid is dirty or burnt, consider a complete fluid flush.
3. Inspect Gear Shift Linkage
  • Remove the center console to access the gear shift mechanism (tools: socket set, flathead screwdriver).
  • Visually inspect the linkage for any disconnections or damaged components.
  • Reconnect or replace any damaged parts as necessary.
4. Test the Brake System
  • Inspect the brake pedal switch to ensure it activates when the brake is pressed.
  • If faulty, replace the brake light switch (tools: socket set, pliers).
  • Test the brake system functionality including fluid levels and brake operation.
5. Examine the Transmission Control Module (TCM)
  • Locate the TCM, usually positioned near the transmission or under the dashboard.
  • Use a multimeter to check for proper voltage and ground connections.
  • If necessary, replace the TCM following the manufacturer's instructions.
