Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, funnel, and transmission fluid.
Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Transmission Fluid

Locate the transmission dipstick (if applicable) or access the fill plug.
Remove the dipstick or fill plug and wipe clean.
Reinsert and remove again to check the fluid level; it should be within the marked range.
If low, add the manufacturer's recommended transmission fluid until it reaches the correct level.

3. Inspect and Repair Gear Selector Linkage

Remove any necessary panels to access the gear selector mechanism.
Visually inspect the linkage for wear or disconnection.
If damaged, replace the gear selector linkage assembly using a socket set to remove bolts.

4. Test and Replace Brake Switch

Locate the brake light switch, usually mounted near the brake pedal assembly.
Use a multimeter to test for continuity when the brake pedal is pressed.
If defective, replace the brake switch by disconnecting the wiring harness and removing the mounting nut.

5. Reconnect Battery and Perform TCM Reset

Once repairs are complete, reconnect the battery.
Use the OBD-II scanner to reset any error codes in the TCM.
Start the vehicle and attempt to shift into gear to test functionality.
