1. Gather Tools and Materials:
Make sure you have all the necessary tools and materials, such as new transmission fluid (check your owner's manual for the recommended type and quantity), a new transmission filter (if applicable), a transmission fluid drain pan, a funnel, a wrench, and a torque wrench.
2. Prepare the Car:
Park the car on a level surface and apply the parking brake. Engage it on park for an automatic or first gear for a manual. Turn off the engine and allow it to cool down.
3. Locate the Drain Plug:
Underneath the car, locate the transmission fluid drain plug. It's usually a 17mm bolt on the bottom of the transmission pan.
4. Place the Drain Pan:
Position the transmission fluid drain pan directly underneath the drain plug. Make sure the pan is large enough to catch all the draining fluid.
5. Drain the Fluid:
Use the wrench to loosen the drain plug and allow the old transmission fluid to drain completely into the drain pan. This may take a few minutes.
6. Replace the Drain Plug:
Once the fluid has drained, replace the drain plug and tighten it securely using the wrench.
7. Locate the Transmission Fluid Fill Plug:
Find the transmission fluid fill plug, which is typically located on the side of the transmission case or near the dipstick tube.
8. Add New Fluid:
Using a funnel, add the recommended amount of new transmission fluid into the fill plug hole. Be cautious not to overfill.
9. Check Fluid Level:
Use the transmission fluid dipstick (usually located near the fill plug) to check the fluid level. Ensure it's between the "Full" and "Add" marks on the dipstick.
10. Replace the Fill Plug:
Once you've achieved the correct fluid level, replace the fill plug and tighten it securely.
11. Start the Car:
Start the engine and let it run for a few minutes. Shift through all the gears, from park to drive and back, while keeping your foot on the brake.
12. Recheck Fluid Level:
Turn off the engine and wait a few minutes to allow the fluid to settle. Then, recheck the transmission fluid level using the dipstick. Ensure it's still between the "Full" and "Add" marks.
Remember, this procedure is a general guideline. It's recommended to consult your car's service manual or consult with a professional mechanic to ensure you follow the proper steps and safety precautions for your specific Hyundai Elantra model and year.
