Troubleshooting transmission issues on a Vauxhall Astra

I've been experiencing some trouble with the transmission on my Vauxhall Astra. The gears seem to be shifting roughly and there's a strange noise coming from the engine. Can anyone provide some insight into what could be causing this issue?

Sounds like your transmission fluid may be low. Check the levels and top up if necessary.

It could also be an issue with your clutch. You may need to have it replaced.

I had a similar issue with my Astra and it turned out to be a faulty transmission control module. Could be worth getting that checked out.
