1. Prepare your materials:
- You will need a manual transmission fluid that meets your vehicle's specifications, a fluid pump or large syringe, a hose or funnel, a drain pan, and new transmission seals/gaskets.
2. Locate the transmission fluid drain plug:
- Your vehicle's transmission fluid drain plug will typically be located on the bottom of the transmission housing; be sure to locate the correct drain plug as there may be other drain plugs for other components located nearby the transmission.
3. Position your drain pan under the transmission fluid drain plug:
- Make sure the drain pan is large enough to catch all the transmission fluid that will drain out.
4. Open the transmission fluid drain plug:
- Use the proper tools to loosen and remove the transmission fluid drain plug.
5. Let the transmission fluid drain:
- Allow all of the old transmission fluid to drain out of the transmission; this could take a few minutes.
6. Close the transmission fluid drain plug:
- Once all of the old transmission fluid has drained out, reinstall and tighten the transmission fluid drain plug.
7. Locate the transmission fluid fill plug:
- The transmission fluid fill plug will be located on the side or top of the transmission housing; be sure to locate the correct fill plug.
8. Use a fluid pump or syringe to fill the transmission with new fluid:
- Use a clean funnel and hose to fill the transmission with new transmission fluid until it reaches the proper level; most vehicles have a fill plug or dipstick that indicates the proper fluid level.
9. Install new transmission seals/gaskets:
- If you removed any seals or gaskets during the process, be sure to install new ones before closing the transmission fluid fill plug.
10. Test drive the vehicle:
- Take the vehicle for a short test drive and verify that the transmission is functioning properly and there are no leaks.
Note that this process may vary depending on your vehicle, so it's important to consult your owner's manual or a professional for specific instructions and guidance on how to flush your manual transmission.
