Instructions:
1. Park the vehicle on a level surface.
- Be sure to put the truck in _park_ mode.
2. Turn of the engine.
- Always wait for the engine to cool down to avoid burns.
3. Locate the transmission fluid drain plug.
- The drain plug is typically located on the bottom of the transmission pan.
4. Place the drain pan under the drain plug.
- Be sure the drain pan is large enough to catch all of the fluid that will drain out.
5. Loosen the drain plug.
- Use the 3/8-inch ratchet and socket to loosen the drain plug.
6. Allow the transmission fluid to drain completely.
- This may take several minutes.
7. Replace the drain plug.
- Once all of the fluid has drained out, replace the drain plug.
8. Locate the transmission fluid fill plug.
- The fill plug is typically located on the side of the transmission.
9. Remove the fill plug.
- Use the 3/8-inch ratchet and socket to remove the fill plug.
10. Insert the funnel into the fill hole.
- Be sure to insert the funnel all the way into the hole.
11. Pour the new transmission fluid into the funnel.
- Add the amount of fluid specified in your owner's manual.
12. Replace the fill plug.
- Once you have added the correct amount of fluid, replace the fill plug.
13. Start the engine and let it run for a few minutes.
- This will circulate the new fluid throughout the transmission.
14. Check the transmission fluid level.
- Use the dipstick to check the transmission fluid level. The fluid should be between the "full" and "add" marks on the dipstick.
Tips:
- If your transmission is equipped with a transmission fluid filter, you should also replace it when you change the fluid.
- If your transmission pan is equipped with a gasket, you should also replace it when you change the fluid.
- Be sure to recycle the old transmission fluid.
- If you are uncomfortable performing this task, you can take your vehicle to a qualified mechanic to have the transmission fluid changed.
