Steps to Properly Drain and Refill ATF in an Automatic Transmission

1. Step 1: Park your vehicle on a level surface and engage the parking brake to ensure stability.
2. Step 2: Locate the transmission fluid pan underneath your vehicle. Consult the owner's manual if uncertain.
3. Step 3: Place a large drain pan underneath the transmission fluid pan to catch the old ATF.
4. Step 4: Carefully loosen the bolts securing the transmission fluid pan, starting from one end to the other. Loosen them gradually to prevent fluid spillage.
5. Step 5: Once the bolts are loosened, carefully remove the pan and set it aside. Allow the remaining fluid to drain fully into the drain pan.
6. Step 6: Clean the transmission pan and the magnet inside it thoroughly using a lint-free cloth.
7. Step 7: Locate and remove the transmission fluid filter, if applicable, and replace it with a new one.
8. Step 8: Reinstall the transmission fluid pan onto the transmission using a new gasket or seal, if necessary. Torque the bolts to the manufacturer's specifications.
9. Step 9: Locate the transmission fluid dipstick and remove it - this is where the refill will take place.
10. Step 10: Using a funnel, slowly pour the recommended ATF into the transmission through the dipstick tube.
11. Step 11: After pouring a reasonable amount, start the engine and let it idle for a few minutes.
12. Step 12: With the engine still running, check the transmission fluid level using the dipstick. Add more fluid if necessary, following the manufacturer's guidelines.
13. Step 13: Once the fluid level is satisfactory, securely reinsert the dipstick and close the hood.
14. Step 14: Dispose of the old ATF properly, following local regulations.

Following these steps will help you properly drain and refill automatic transmission fluid, ensuring optimal performance and longevity of your transmission.
