1. Turn Off the Engine and Let it Cool Down: Ensure the engine is turned off and has had enough time to cool down.
2. Find the Transmission Dipstick Tube or Fill Plug: Locate the dipstick tube or fill plug on the transmission housing. Usually, it's marked with "ATF" or "Transmission Fluid."
3. Clean the Dipstick or Plug: Clean the dipstick or the fill plug to prevent any debris from entering the transmission.
4. Check the Transmission Fluid Level: If it's a dipstick, pull it out, wipe it clean, and reinsert it. When you take it out again, you should be able to read the fluid level on the dipstick. If it's a fill plug, it usually acts as a level indicator itself and will have markings to show the proper fluid level.
5. Add Transmission Fluid: If the fluid level is low, add the recommended type and amount of automatic transmission fluid. It's essential to consult your vehicle's owner's manual to determine the fluid specifications. Avoid overfilling the transmission.
6. Recheck the Fluid Level: After adding fluid, recheck the dipstick or fill plug to ensure the level is at the recommended mark.
7. Clean Up: Clean up any spilled fluid from around the fill point.
Remember, adding transmission fluid may vary depending on your vehicle's model and make. Consult the owner's manual for accurate instructions regarding your specific vehicle and follow any specified safety precautions. If you feel uncomfortable or unsure about adding transmission fluid yourself, it's best to have a professional mechanic do it for you.
