Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick, wipe it clean, and reinsert it.
Remove it again to check the fluid level; it should be within the specified range.
If low, add the manufacturer-recommended transmission fluid slowly until the correct level is reached.
Inspect the fluid condition; if it’s dark or burnt, consider a fluid change.

3. Inspect Transmission Linkage

Raise the vehicle securely using jack stands.
Locate the transmission linkage and check for any visible wear or disconnections.
Tighten any loose bolts and adjust the linkage if necessary.
If damaged, replace the linkage components as needed.

4. Check Clutch (Manual Transmission)

If manual, check the clutch fluid reservoir and ensure it is filled to the appropriate level.
Bleed the clutch system if air is present in the line.
Inspect the clutch master and slave cylinders for leaks or failure; replace if necessary.

5. Address Error Codes

If error codes were found, refer to a repair manual for specific diagnostic procedures related to the codes.
Clear the codes and take the vehicle for a test drive to see if they return.
