Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety.

2. Inspect and Top Off Transmission Fluid

Locate the transmission dipstick, remove it, and wipe clean.
Reinsert dipstick, remove it again, and check fluid level.
If low, add the recommended transmission fluid type.
Check for burnt smell or debris in fluid, indicating possible issues.

Visually check the transmission linkage for any signs of damage or disconnection.
If damaged, replace the linkage with the appropriate part.

4. Examine Shift Cable

Locate the shift cable connected to the transmission.
Inspect for fraying or broken sections.
If damaged, disconnect the cable from both ends and replace it.

5. Test Brake Light Switch

Locate the brake light switch near the brake pedal.
Check for electrical continuity using a multimeter.
If defective, replace the brake light switch.

6. Test Transmission Solenoids

Access the transmission by removing the necessary panels.
Disconnect the electrical connectors from the solenoids.
Use a multimeter to test the resistance of each solenoid according to manufacturer specifications.
Replace any faulty solenoids.
