Its done 84000 miles.
I don't think I've changed the gearbox oil on any of my previous cars (on higher mileages), but wondering if I should?

if you don't maintain it then it will break

vauxhall say the gearbox is "sealed" for "life"
not really sealed as it has a drain and fill ports, and life of the car being 100k miles/5 years

i keep my cars until they die which is a very long time, still have a 20year old honda civic sat on my drive, engine still runs nicely

i changed my gearbox oil on my insignia at 100k miles, hoping to get this car to atleast 200k miles
