How can I troubleshoot the transmission issues in my Vauxhall Insignia?

I have been experiencing some issues with my Vauxhall Insignia's automatic transmission. It sometimes feels jerky when shifting gears and there is also a delay in acceleration. What could be the cause of this and how can I fix it?

Based on your description, it seems like your transmission may be low on fluid or the fluid is dirty. First, check the transmission fluid level and color. If it is low or dark brown, it may be time for a fluid change.

Another possibility is that your transmission filter is clogged. This can cause similar issues and can easily be fixed with a filter replacement.

If the above solutions do not resolve the issue, it is possible that there is a problem with the transmission solenoid or sensors. This will require a professional diagnosis and repair.
