Solution

1. Preparation

Gather tools: a clean lint-free cloth, funnel (if adding fluid), and transmission fluid (check owner's manual for the correct type).
Ensure the vehicle is parked on level ground with the engine running.

2. Check Fluid Level

Remove Dipstick: Carefully pull out the transmission dipstick.
Wipe Dipstick Clean: Use the lint-free cloth to wipe off any fluid on the dipstick.
Reinsert Dipstick: Insert the dipstick back into the tube completely.
Remove and Check Level: Pull out the dipstick again and check the fluid level against the markings. The fluid should be within the "Hot" range if the engine is warmed up.

3. Add Fluid (if necessary)

Locate Fill Tube: If the fluid level is low, locate the transmission fluid fill tube.
Add Fluid: Use a funnel to add the correct type of transmission fluid (consult your owner's manual for specifications) to the fill tube slowly.
Recheck Level: After adding fluid, recheck the level using the dipstick to ensure it is within the appropriate range.
