Why is my Vauxhall Insignia not shifting gears smoothly?

I have noticed that my Vauxhall Insignia is not smoothly shifting gears, especially when accelerating. What could be causing this issue and how can I fix it?

This could be due to a worn transmission or a faulty clutch. I recommend bringing your car to a certified mechanic for a diagnostic check.

It could also be an issue with the transmission fluid. Check the fluid level and condition and top up or replace if necessary.

Another potential cause could be a misaligned shift linkage. This can be adjusted by a mechanic to improve gear shifting.
