Solution

1. Preparation

Gather tools and materials:
- Clean rag
- Funnel (if adding fluid)
- New transmission fluid (check specifications in the owner’s manual)
- Safety gloves
Ensure the vehicle is on a level surface and the engine is warm.

2. Check Fluid Level

If equipped with a dipstick:
1. Remove the dipstick and wipe it clean with a rag.
2. Reinsert the dipstick fully and then remove it again to check the fluid level.
3. The fluid should be within the “Hot” range if the engine is warm.
If using a fill plug:
1. Remove the fill plug located on the transmission case.
2. Insert your finger or a measuring tool into the fill hole to check if fluid is present at the bottom of the hole.
3. If fluid does not touch your finger, the level is low.

3. Add Fluid (if necessary)

Using a funnel, slowly add the recommended type of transmission fluid through the dipstick tube or fill plug until the proper level is reached.
Recheck the fluid level after adding fluid to ensure it is within the correct range.

4. Final Steps

Replace the dipstick securely or reinstall the fill plug.
Start the engine and let it run for a few minutes.
Recheck the fluid level once more to ensure it is at the correct level.
