- Transmission fluid pump
- OBD-II scanner
- Drain pan
- Funnel
- Clean rags
Safety Warnings:
- Ensure the vehicle is on a flat surface and properly secured with jack stands if elevated.

2. Drain Old Transmission Fluid

Locate the transmission drain plug beneath the vehicle.
Position the drain pan beneath the drain plug.
Remove the drain plug using the appropriate socket and allow the old fluid to fully drain into the pan.
Inspect the drain plug for metal shavings and clean if necessary.

3. Replace Transmission Filter (if applicable)

Locate the transmission filter (if your model includes one).
Remove any retaining bolts or clips securing the filter.
Carefully pull the old filter out and replace it with a new filter, ensuring a proper seal.
Reattach any bolts or clips to secure the new filter in place.

4. Add New Transmission Fluid

Reinstall the drain plug and torque it to the manufacturer’s specification (consult the service manual for the exact value).
Use the transmission fluid pump to add the new transmission fluid through the fill tube or dipstick tube.
Consult the owner’s manual for the correct type and quantity of transmission fluid.

5. Check Fluid Level

Start the engine and allow it to idle for a few minutes.
Shift through all gear positions to circulate the new fluid.
With the engine still running, check the fluid level using the dipstick (if equipped) and add more fluid as necessary to reach the correct level.
