How to properly maintain the gearbox on a Vauxhall Insignia?

I have a Vauxhall Insignia and I have noticed that the gearbox is not functioning as smoothly as it used to. What can I do to maintain it and prevent any potential issues?

It is important to regularly check the transmission fluid and change it according to the manufacturer's recommendations. This will ensure the gearbox is properly lubricated.

Make sure to have the gearbox inspected by a qualified mechanic at least once a year. They can identify any issues early on and prevent major problems down the line.

Driving aggressively and frequently towing heavy loads can put extra strain on the gearbox. Try to avoid these habits to prolong the life of your gearbox.

Consider using a synthetic transmission fluid for better performance and longevity. It can also help with smoother shifting.
