Park the car on a level surface. Turn off the engine and allow it to cool down.
Locate the transmission fluid dipstick. It is located in the engine bay, near the back of the engine. It is a long, thin tube with a yellow handle.
Pull the dipstick out and check the fluid level. The fluid should be between the "FULL" and "ADD" marks on the dipstick.
If the fluid level is low, add fluid through the dipstick tube. Use a funnel to add the fluid slowly. Do not overfill the transmission.
Check the fluid level again and make sure it is between the "FULL" and "ADD" marks.
Reinsert the dipstick and close the hood.
