Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal.

2. Check Transmission Fluid

Remove the transmission dipstick.
Wipe it clean, reinsert, and remove it again to check the fluid level.
If low, add the recommended transmission fluid type specified in the owner’s manual.
If the fluid is dark or has a burnt smell, consider a fluid change.

3. Inspect Clutch and Brake Systems (if applicable)

For manual transmissions, check the clutch pedal for proper operation.
If the clutch pedal feels spongy or goes to the floor, bleed the clutch hydraulic system.
For automatic transmissions, ensure the brake pedal switch is functioning, as it prevents shifting if faulty.

4. Inspect Transmission Linkage

Remove any plastic covers to access the transmission linkage.
Check for any loose or disconnected linkage components.
Tighten any loose bolts and reattach any disconnected parts as necessary.

5. Electrical System Check

Use a multimeter to check the voltage on the battery. It should read between 12.4 - 12.7 volts.
Ensure the alternator is supplying adequate voltage (around 13.8 - 14.4 volts while the engine is running).
Inspect fuses related to the transmission control module and replace any blown fuses.
