- Remove the transmission dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the fluid level.
- If low, add the appropriate type of transmission fluid (check owner's manual for specifications).
- Check the fluid condition; if dark or burnt, a fluid change may be necessary.

3. Inspect and Repair Leaks

Sub-steps:
- Locate the source of any fluid leaks by inspecting seals, gaskets, and hoses.
- Replace any damaged seals or gaskets using a sealant if needed.
- If hoses are cracked or damaged, replace them with new ones.

4. Transmission Linkage Inspection

Sub-steps:
- Visually inspect the transmission linkage and cables for wear or disconnection.
- If any components are loose or damaged, tighten or replace them accordingly.

5. Clutch System Inspection (Manual Transmission)

Sub-steps:
- Inspect the clutch fluid reservoir and ensure it is filled to the proper level.
- Check for any leaks in the hydraulic line.
- If the clutch master or slave cylinder is faulty, replace it.

6. Transmission Filter and Fluid Change (if necessary)

Sub-steps:
- If transmission fluid is burnt or dirty, drain the old fluid and replace it.
- Remove the transmission pan and replace the transmission filter.
- Reinstall the pan with a new gasket and torque the bolts to manufacturer specifications.
