What are the common transmission issues in a Vauxhall Astra?

I've been experiencing some problems with my Vauxhall Astra's transmission recently. It's making strange noises and feels jumpy when shifting gears. I've also noticed a delay in acceleration at times. What could be causing these issues and what should I do?

Based on your description, it sounds like your transmission fluid may be low or contaminated. You should check the fluid level and condition and if necessary, have it replaced or flushed by a professional mechanic.

Another possible cause could be a faulty transmission control module. You should have it checked and potentially replaced by a certified technician.

Proper maintenance of your transmission, such as regular fluid changes, can help prevent these issues. It's also important to follow the manufacturer's recommended service intervals.
