How do I properly maintain my Vauxhall Movano's transmission?

I recently purchased a Vauxhall Movano and I want to make sure I am properly maintaining the transmission. What steps should I take to ensure proper functioning and longevity?

Regularly check and replace transmission fluid according to the manufacturer's recommended schedule. This will keep the transmission operating smoothly and reduce the risk of potential damage.

Avoid towing heavy loads for long periods of time as this can put extra strain on the transmission. If you do need to tow, make sure to take frequent breaks to allow the transmission to cool down.

Consider installing a transmission cooler if you frequently haul heavy loads or live in a hot climate. This can help reduce the risk of heat-related damage to the transmission.
