Where do you add transmission fluid to a 2003 ford explorer?

To add Transmission Fluid to a 2003 Ford Explorer, locate the transmission dipstick, which is usually found near the back of the engine bay. Pull out the dipstick, wipe it clean, and reinsert it to check the fluid level. To add fluid, use a funnel to pour the appropriate type of transmission fluid into the dipstick tube until the correct level is reached. Ensure the vehicle is on a level surface and that the engine is running while checking the fluid level.
