I have recently bought my first Range Rover Sport HSE 2007 and so far very happy with it.

However, as I was driving it earlier today a warning light came on shaped like a gearbox.

Any ideas what this could be and can I still drive it around town?

I am taking it for a diagnostic next Thursday but my garage is 25 miles from home.

I'm just concerned that if I continue to drive I may cause some unnecessary damage?
