Hello
Just had my disco 3 serviced and have been told i have a leak on the gearbox. The machanic says he carnt find were it is coming from but it is defenatly gearbox oil and seems to be from the top. I havnt got any on my drive oil that is ? Can anybody help. Do they have a common fault and is he right in saying that they have life time oil in it so it never gets changed

Any one!!!!!!
