  2. Locate the transmission dipstick, which is usually labeled and located near the back of the engine bay.
  3. With the engine warmed up and running, pull out the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and pull it out again to check the fluid level. The dipstick will have markings indicating the “Full” and “Add” levels.
  5. If the fluid level is below the “Add” mark, you’ll need to add more fluid. Use a funnel to pour the recommended transmission fluid slowly into the dipstick tube.
  6. Check the fluid level again and repeat the process until it reaches the “Full” mark.
  7. Once you’re satisfied with the fluid level, securely reinsert the dipstick and close the hood.
