How do I top up the gearbox oil in a 2012 Chevrolet Spark?
I think the gearbox oil is low in my car, but I'm not sure how to top it up. I thought the oil with the dipstick was the engine oil but I was told that I could use that to top up the gearbox oil. Is this wrong and if it is, how do I top up gearbox oil for this car? (It's a 1.2L engine and I have the correct oil).
