  1. Start by parking your vehicle on a level surface and engaging the parking brake.
  2. Locate the transmission fluid dipstick. It is usually labeled and can be found near the back of the engine compartment.
  3. With the engine running and the transmission warmed up, carefully pull out the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the appropriate range for the fluid level.
  5. If the fluid level is below the recommended range, you can add transmission fluid through the dipstick tube. Use a funnel to avoid spills and add small amounts at a time, checking the level frequently until it reaches the proper range.
  6. Be cautious not to overfill the transmission, as it can lead to damage. It’s always better to add less fluid and then top it up if needed.
  7. Once you’ve reached the correct fluid level, securely reinsert the dipstick and ensure it is properly seated.

Remember, safety is paramount when working with your vehicle. Always exercise caution, wear appropriate protective gear, and consult a professional if you’re unsure about any aspect of the process.
