Can the Vauxhall Grandland's transmission be upgraded to a higher gear ratio?

I've noticed that my Vauxhall Grandland seems to struggle with uphill climbs and I was wondering if there is a way to upgrade the transmission to a higher gear ratio to improve its performance in these situations.

Yes, it is possible to upgrade the transmission to a higher gear ratio but it is not recommended. Your Grandland's current gear ratio is matched to its engine and any changes could potentially cause more harm than good.

Instead of upgrading the gear ratio, you can try using the manual gear shift option. This will allow you to adjust the gear according to the terrain, which should help with uphill climbs.

In my experience, it's not the gear ratio that's the issue but rather the engine's performance. Have you considered getting a tune-up or taking your Grandland to a mechanic for a check-up?
