What is the best way to maintain the Ford Galaxy's transmission?

I just bought a used Ford Galaxy and noticed that it's starting to shift gears a bit awkwardly. I want to make sure I take good care of the transmission to avoid any expensive repairs in the future. Any tips on how to do this?

Regularly change the transmission fluid and filter, and make sure to use the recommended type for your specific model.

Check for leaks regularly and get them fixed promptly to prevent damage to the transmission.

Avoid hard acceleration and sudden shifts while driving to prolong the life of your transmission.
