Solution

1. Preparation

Gather necessary tools: funnel, clean lint-free cloth, a container for any excess fluid, and gloves.
Ensure the vehicle is parked on a level surface and the engine is at operating temperature.

2. Locate the Dipstick

Open the hood and secure it.
Identify the transmission dipstick or fill port, which is usually located near the back of the engine bay. It may be marked with a colored handle.

3. Check Fluid Level

Pull out the dipstick and wipe it with a clean cloth to remove any old fluid.
Reinsert the dipstick fully, then remove it again to check the fluid level.
The fluid should be within the marked range on the dipstick. If it is low, you will need to add fluid.

4. Adding Transmission Fluid (if necessary)

If the fluid level is below the recommended range, use a funnel to add the appropriate transmission fluid (refer to the owner's manual for the specific type).
Add fluid gradually, checking the level frequently to avoid overfilling.

5. Final Steps

Once the correct level is reached, reinsert the dipstick securely.
Close the hood and ensure it is latched properly.
