Hi guys I've just brought a 2012 Volvo V50 r design d3 with a GEARTRONIC box, you get a slight jump when selecting drive now I'm not sure but before changing the gearbox I would like to change the gearbox oil is it possible to do so and if so do you think it will help. As I have been told it is a sealed unit and does not need changing and will last the lifetime of the car BUT who is to say that the lifetime of the car is when the gearbox blows up because of 10 year old worn out oil??? DOES ANYONE HAVE ANY KNOWLEDGE ON THE SUBJECT
