Notice the end of the dipstick opposite the handle. The markings may be notches, holes, lines, or engraved text. Place the dipstick into the tube from which it was removed being sure to insert it completely. Remove it again and check the level on the dipstick. If the oil is low, add only enough oil to bring the level up to the full mark.
Oil is added to the engine by removing the screw cap on the top of the engine.
Check the oil a final time to insure that it is indeed full, then fully reinsert the dipstick. Begin by turning on your vehicle and let it run for a minute while you locate the transmission dipstick. After you have located the dipstick, remove it and wipe it clean with the rag. Notice the markings and reinsert it fully. Remove the dipstick again, and check the level of the fluid.
