Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Transmission Fluid

Locate the transmission dipstick (if equipped) or the fill plug.
Pull the dipstick out, wipe it clean, and reinsert it to check the fluid level.
If low, add the appropriate transmission fluid (refer to owner’s manual for specifications).
If the fluid is dirty or burnt, consider a transmission flush and fluid replacement.

3. Inspect Gear Shift Linkage

Use a socket set to remove any covers obstructing access to the gear shift linkage.
Visually inspect the linkage for any signs of wear or disconnection.
Adjust or replace any damaged linkage components as necessary.

4. Test the Brake Light Switch

Locate the brake light switch, typically mounted near the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
If the switch is malfunctioning, replace it with a new switch.

5. Diagnose Transmission Control Module (TCM)

Reconnect the battery and use the OBD-II scanner to check for TCM-related error codes.
If codes are present, follow manufacturer-specific troubleshooting steps to resolve issues.
If necessary, replace the TCM according to manufacturer specifications.

6. Reassemble and Test

Reinstall any components or covers removed during inspection.
Reconnect the negative battery terminal.
Start the vehicle and attempt to shift into reverse to check if the issue is resolved.
