* Place a drain pan under the drain plug.
* Unscrew the drain plug carefully. Be careful as the liquid is hot.
* Allow the liquid to drain completely.
3. Removing the automatic transmission pan
* Unscrew the bolts securing the automatic transmission pan to the housing. Typically these are 10 or 12 mm bolts.

* Inspect the gasket for damage or wear. If the gasket is damaged, it must be replaced.
4. Replacing the automatic transmission filter
* Find the old automatic transmission filter in the pan.
* Pull out the old filter and replace it with a new one.
* Make sure the new filter is installed correctly in the direction of fluid flow.
5. Installing the automatic transmission pan
