1. Park your car on a level surface and turn off the engine. Allow the engine to cool down to prevent burns.
2. Locate the transmission fluid dipstick. It is usually located near the back of the engine, near the transmission case. It is usually marked with a bright color, such as orange or red, and may have the word "Transmission" written on it.
3. Pull out the dipstick and wipe it clean. Look at the level of the transmission fluid on the dipstick. It should be between the "Full" and "Add" marks on the dipstick.
4. Add transmission fluid if necessary. If the fluid level is low, insert the funnel or hose into the transmission fluid dipstick tube and carefully add fluid until the fluid level reaches the "Full" mark on the dipstick.
5. Reinsert the dipstick. Double-check to ensure that the transmission fluid level is now between the "Full" and "Add" marks on the dipstick.
