Do I need to change my transmission fluid in my Vauxhall Astra?

I have a 2010 Vauxhall Astra and I am wondering if I need to change my transmission fluid. I have heard conflicting opinions and would appreciate some guidance.

Yes, it is recommended to change your transmission fluid every 60,000 miles or every 5 years.

No, it is not necessary to change your transmission fluid until you reach 100,000 miles.

It depends on your driving habits and conditions. If you frequently tow heavy loads or drive in stop-and-go traffic, it may benefit you to change your transmission fluid more often.
