What are the common issues with Vauxhall Corsa's gearbox?

I've been experiencing some jerking and grinding noises while shifting gears in my Vauxhall Corsa. What could be causing this and how can I fix it?

It is possible that your gearbox oil may be low or contaminated. Try checking and replacing it first before taking any further action.

Another common issue could be a worn out or damaged gear synchronizer. This may require repairs or replacements by a professional mechanic.

Misaligned or damaged shift linkage can also cause rough shifting and grinding noises. Have a mechanic inspect and properly adjust or replace the linkage if necessary.
