How to properly maintain the gearbox in a Vauxhall Movano?

I recently purchased a Vauxhall Movano and I want to ensure that the gearbox is properly maintained to avoid any unexpected issues. Can you provide some tips for maintaining the gearbox?

Make sure to change the transmission fluid and filter according to the manufacturer's recommended schedule.

Avoid aggressive driving and sudden acceleration as it can put extra strain on the gearbox.

Regularly check the transmission fluid levels and top up if necessary.
