Place a bucket underneath the transmission drain plug. Unbolt the plug to allow the fluid to drain.

Unbolt the transmission pan, and remove it. Use a scraper and rag to remove the old gasket and residue on the pan and mounting surface.
- Replace the old filter
Unbolt or pry the old filter off with a flathead screwdriver, and replace it with the new filter.
- Install a new gasket
Apply adhesive to the new gasket, and install it on the transmission pan.
- Reinstall the transmission pan
Mount the transmission pan, and bolt it into place.
- Add new fluid
Ensure the transmission drain plug is secure, and start the engine. Fill the transmission reservoir with new fluid.
