What is the best way to maintain the transmission on a Vauxhall Astra?

I've noticed my Vauxhall Astra's transmission slipping and I'm not sure how to fix it. What steps should I take to properly maintain the transmission and prevent any further issues?

First and foremost, it's important to regularly check and change the transmission fluid according to the manufacturer's recommendations. This will help keep the transmission running smoothly and prevent any potential damage.

In addition to changing the fluid, make sure to also regularly check the transmission for any leaks or damage. If you notice any leaks or damage, it's important to address them as soon as possible

Another important step is to properly warm up the transmission before driving. This allows the fluid to properly flow and lubricate all the necessary components. It's especially important in colder climates.
