Solution

1. Preparation

Gather necessary tools and materials.
Tools Required:
- Transmission dipstick (if not included with the vehicle)
- Lint-free cloth or paper towels
- Funnel (if adding fluid)
Ensure the vehicle is on a level surface and the engine is at normal operating temperature.

2. Check Fluid Level

Remove the transmission dipstick.
Wipe the dipstick clean with a lint-free cloth.
Reinsert the dipstick fully back into the tube.
Remove the dipstick again to check the fluid level against the markings.
- If the fluid is at the 'Full' mark, it is at the correct level.
- If the fluid is below the 'Add' mark, additional fluid is required.

3. Add Fluid (if necessary)

If the fluid level is low, use a funnel to add the appropriate type of transmission fluid (refer to the owner’s manual for specifications).
Add fluid gradually, checking the level frequently to avoid overfilling.
Ensure the fluid reaches the 'Full' mark on the dipstick.

4. Recheck and Clean-Up

Reinsert the dipstick securely after checking or adding fluid.
Clean any spills on the engine or surrounding areas using a cloth.
