Solution

1. Preparation

Gather necessary tools and materials:
- Clean lint-free cloth
- Funnel (if checking via fill plug)
- Transmission fluid (if needed for topping off)

2. Checking the Fluid Level

For Dipstick Type:
1. Insert the cleaned dipstick back into the tube completely.
2. Remove the dipstick again and check the fluid level against the marks on the dipstick.
3. Ensure the fluid is between the "Full" and "Add" marks.
For Fill Plug Type:
1. If no dipstick is present, use a funnel to add transmission fluid through the fill plug.
2. Check the fluid level by inserting a clean finger into the fill hole; fluid should be at the edge of the hole.
3. If necessary, add the correct type of transmission fluid (refer to owner's manual for specifications).

3. Finalizing

If the fluid was low, add the necessary amount of transmission fluid and recheck the level.
Ensure that the dipstick or fill plug is securely reinstalled.
