Solution

1. Preparation

Gather tools: funnel, clean cloth, and possibly a transmission fluid pump.
Ensure the vehicle is parked on a level surface with the engine warmed up.

2. Locate the Dipstick or Fill Plug

Open the hood and secure it.
Identify the transmission dipstick, which is typically located near the back of the engine bay.
If no dipstick is present, locate the fill plug on the transmission housing, which may require removal of some covers.

3. Check Fluid Level

If using a dipstick, remove it and wipe it clean with a lint-free cloth.
Reinsert the dipstick fully and remove it again to check the fluid level against the marked indicators.
If checking via a fill plug, use a funnel to add fluid if the level is low; fluid should reach the bottom of the fill plug hole.

4. Add Transmission Fluid (if necessary)

If the fluid level is low, add the recommended type of transmission fluid (refer to the owner's manual).
Use a funnel for precision to avoid spills.
Check the fluid condition; it should be a bright red color and not smell burnt.

5. Final Check

Reinsert the dipstick or fill plug securely.
Close the hood and take the vehicle for a short drive to allow the fluid to circulate, then recheck the level if necessary.
